My First Post! How's it going everybody! (Newb Alert)
I just purchased a Bell HTC Desire Z from a classified ad off of an older man who found that the phone wasn't fully functioning. The poor guy probably paid around $400CDN for the phone, but I ended up eventually buying it from him for $250.
Here is what is wrong with the phone:
1. Power Button-does not work, neither on or off...basically fully unfunctional and only way to turn phone off is battery pull...fun stuff! (planning on using the Teardown/Repair guide by verkion - recommended?)
2. The In-Call speaker (where you put your ear while talking on the phone) seems to have very limited sound, perhaps something has been destroyed on the inside, how all other sound mechanisms work, such as the external speaker and internal speaker w/ headphones. (planning on using the Teardown/Repair guide by verkion - recommended?)
3. The Digitizer, well parts of it (along the left edge of the phone when upright) are unresponsive, so called blind spots which when touched are unresponsive on the digital keyboard along with the home button (house shaped icon) - especially frustrating when browsing web pages because I have to click back like 10 times to get home... (planning on using the Teardown/Repair guide by verkion - recommended?)
4. It is a Bell branded phone, Locations does not work! however I have done the research on the forums and I think I can figure out the whole Rooting thing out, but advice is appreciated! (planning on using gtrab's FAQ for Dummies for the rooting, s-off, and de-branding)
Now...I am not really technologically inclined to the level most of you probably are, but I am good with my hands and really interested/curious about this whole mission I need to complete, so I can fix this phone myself instead of paying $100 for cell phone repair...plus its a nice challenge right?
Do you guys recommend that I take care, or at least attempt to fix the power button issue before I root the phone to a previous, unbranded firmware which will allow me to use Locations? This only makes sense right, because I am going to need the power button for that process?
I know this is a lot to ask, but I just need some pushes and shoves to get me on the right track to try and get this to work, so if it is technologically impossible or excessive...please let me know how I can fix 4 of these problems methodically in a safe and professional way!
Once again, I appreciate it.
Thanks in Advance
EDIT: My prediction is that the individual who originally owned this phone dropped it and as a result the digitizer, power button, and speaker were all affected...but of course I am no expert.
To me it sounds like the flex cable has been damaged. It would definitely cause all these things at once.
I'm pretty sure you need to fix the power button before rooting because you need the power button to actually root it.
Hmmm,
Never thought of that but it sure seems like a better diagnosis. The flex cable originates in the bottom half of the phone in the same compartment that the z hinge is found right?
It is also the flexible strip that runs through the middle of the phone when the hinge is half-way positioned, connecting the lcd/digitizer to the main motherboard of the phone?
I geuss replacing the flex cable would still involve the Teardown/Repair, however I dont think I will need to replace a power button, speaker, or digitizer IF!...that is the case.
Any other ideas on this?

Yes thats the flex cable, it is built into the pcb behind the lcd, so the whole pcb has to be replaced AFAIK. Yes it requires a full tear down to do it, fairly basic to do, my phone is in pieces atm because the lcd needs replacing.
If the flex cable is the problem then none of those parts need replacing, it would be very unlikely in my opinion for all those parts to fail from a drop without it being flex cable related, possible though.
Link to the teardown, some steps in the middle are unneccesary for what you need. http://tjworld.net/blog/htc-desire-z-tear-down

Hey, do you know where I can get a replacement pcb if I decide to take that route man? Seems hard to find that as a single part for sale...
I assume people replace their whole phone if they have a problem like mine :/
You wasted your freaking money on that phone!
250 is a huge waste!
You might as well add a line to your friends for the contract price.

it's not THAT bad...considering a brand new one unlocked DZ goes for 450+ and i knew I could fix parts of the phone so for -200 cheaper...i don't know bro!
I just need to know if a replacement pcb is possible to get, or maybe just the flex cable is damaged in which I wouldn't need to replace something so crucial.
Who knows what to do?
EDIT: 450 where I live...Ontario, CA.
...i dunno...could even be water damage that did the deed to that phone....in which case you could be replacing a pcb...or not....I've seen water-loged phones come back to life before....sad thing is it might cost you a few to fix it properly...
Totally agree 250 was to steep...that guy probably paid 79 on contract for it....

Wow about the whole coming back to life thing you just said...thats exactly what my digitizer just did, so the left side of my lcd is now working including the home button!
Im guessing the touch panel ribbon was loose but it somehow shifted to functionality.
Great...now for the in ear speaker and power button, and 250 wont seem too bad!
Edit: anyone know how I can look for past signs for water damage like a colored change in a sticker or something?

There are 2 water damaged indicator stickers, 1 under battery and, 1 under the back housing, you can see it through the opening where the top tab of the battery door latches.
Edit: Forgot.... 1 on the battery too.
What color would the stickers be? They are both white, does that mean anything?
If they are pink they got wet.

^^ What they said.... Pink or Red
250 is quite a bit for a device with issues, but good news is it isn't water damage by the sounds of it.
I'm an aviation electronic tech, and your symptoms definetly sound like a loose interface ribbon. If I were u id haul it apart and reseat the flex cable you guys are talking about. I would put a 85% chance that's the issue.
good luck, and welcome fellow canuck to xda and dz family

Sounds good guys.
However...even if it is probably the flex cable that is causing the remainder of my problems:
1. the in call speaker being super quiet
2. power button not working
Is there any other chance that the speaker and power button areas have loose connections? what should i look for when i open the phone aside from ribbon/flex cable connections?
I need to get the power button fixed because then i can move onto rom modifications and stuff to finally get locations!
Where can i get a htc desire z/g2 motherboard??
i dropped my phone and something inside of it something got loose, now it wont charge or turn on
Just took it to a repair guy, he opened it up and said everything seems fine....no corrosion or anything from water...but the phone wont power on....any one here have any ideas? just shoot em, im willing to take anything

I bought a second hand phone and it did turn on however there were a numbers of problems with my phone, it had a power button that didnt work, unresponsive parts on the lcd and a quiet in call speaker.
Your best bet before trying to replace the whole pcb is opening your phone using a teardown guide
http://tjworld.net/blog/htc-desire-z-tear-down
Make sure you read it a couple of times and go through the pics so you know what your dealing with, find the power button, make sure its intact and adjust the ribbon cables.
Otherwise just find a cell phone repairer on a classified ad like criagslist or kijiji.

Yes. Start simple. First check your electron hose to make sure you are getting power to the device. Also check the battery as well as the prongs that connect with the battery tabs. If things are good there, then think about tearing into the phone.

no no, dont say that. This phone was fine for 3 months, i dropped it at a club i went to and water got inside the phone....i took it to 3 repair people and they all said the Main PCB motherboard is damanged (water) soo does anyone have any idea where i can find a motherboard?? i have no problem with costs of replacing it. As long as its not more than the phone itself.

Hey i found these 3 ads on ebay...do you guys think that a swap of the motherboards would be fine? heres the ads. I contacted the seller and they said the battery was used and thats it but phone seemes operational....i know its a risk, but is it worth it guys?
..need help on this one.
why swap the motherboards if the new phone is working fine. Just transfer data and you're done surely?

Reason being the other phones have minor problems, like speaker doesnt work, or some of those phones wont pick up signals and i think thats due to a bad radio flash or if i just flash a radio everything should be working fine.
can someone please clarify this? if i buy a phone with a speaker problem and transfer the main PCB board to my old phone...will there still be a speaker problem? or is the speaker a separate unit itself and not related to the pcb board?

one of the phones i am bidding for says it might not be able to guarantee a connection to mobile network (send sms,make calls) could that be a radio flash problem? would i be able to fix that??
another is one of the phones boots on and shuts off, i take it that could be a bad flash or something? its only about $20. just trying to weigh my options cause the new phones are lkike bidding for $350 lol im not that rich yet
I found out that my MOTHERBOARD is fine. There was water damage but not enough to go inside to the main board! My dad tested the battery voltage and found i wasnt getting any voltage.
i went to future shop and found a lady to let me use her battery and sure enough the battery was working and phone powered on!!! so i guess my battery was shot from dropping and popping out of phone while recording a video.

Those look like the batteries I got. They were about 1/2 of the claimed mah rating. Worst case, they wiill get you running, and that charger is pretty good.

Hi all. In need of a bit of advice here. Hope this is in the right forum.
My beloved DHD has suffered from one too many falls. Despite being protected in an Otterbox Commuter case, he now lies on his deathbed. Even though I was considering an upgrade, I'm thinking I might want to stretch out his life for as long as possible instead. So I've come here to ask for repair advice.
- The phone seems structurally sound from the outside, no damage besides minor aesthetic scratches from before the phone was protected by the Otterbox.
- It appears to boot. Makes the vibration noise etc. Heck the alarm even went off the other morning, at the set time of 0630.
- Screen does not function at all. Lifeless. But not broken in any way externally. Because of this, had to pull the battery to shut the alarm off.
- When plugged in to charge, charging light indicator does not illuminate.
Any ideas?

Cheers, although I'm gonna try a different approach for now.
Any ideas? Can anyone point me in the right direction of some advice?
Sounds like 2 things. Broken lcd and a broken charging port. It wouldn't be worth repairing. You could buy one second hand on ebay for aboot £120.

Thanks for that. Considering trying to sell it broken, for parts. Only thing that concerns me is any sensitive data that may be readily accessed by someone who knows how to get to it.
Is there a way to wipe it?
You could use another dhd with the same firmware and copy the key/button presses and reset it in bootloader mode.

Could also be that the connector for the screen has been dislodged due to being drop to many times you mite try opening it up and see if it is that.

Hi, thanks for the response. So I assume you're referring to this part here?
http://www.parts4repair.com/htc-desire-hd-lcd-screen-fpc-connector/
Seen in this disassembly video from the 3:05 minute mark?
http://www.youtube.com/watch?v=JfatoeWbMRk

I have a problem similar to yours. But in my case, I'd turned the phone off to go to the cinema and the LCD and touch never turned on again.
In order to erase your data, did you try overwriting a stock rom? (In case it's just the charging LED that is broken)
That sucks! Self detonating phone. Does yours still vibrate and 'turn on'?
Haven't actually managed to clear the data. I'm ordering this part here (http://www.parts4repair.com/htc-desire-hd-lcd-screen-fpc-connector/) and I'm going to attempt to pull it apart and fix it.
If I can get it to work again I'll sell the One V I'm using and go back to the old faithful!
Well this saves me from starting a new thread haha
Anyway i am having the exact same problem as you have.
My dad brought home a Desire HD from work wich was not working so i am trying to fix it.
The phone boots, it vibrates ones and after a minute it makes the boot sound.
But nothing responses and the lights wont turn on.
Also no charging light..
Also it does not charge but usb does connect.
Could this be the FPC connector or the screen?
Hmmm...interesting, exact same issue as mine.
Well, I've ordered the FPC connector replacement part I linked above...going to attempt to play around with it when it arrives and see if I can breathe new life into the phone. So I can tell you how that goes...
Although:
1. Would the charging light and screen problem be connected? Is this feasible? Or does it suggest something else is likely shot?
2. I believe the FPC connector requires a solder to replace. This could be a bit ambitious on my part to attempt to repair...any ideas on what sort of a solder would be suitable?

no clean flux core solder would work best, preferably something very thin (about .015"). A small bottle of noclean flux would also help and you probably will need lead free solder as that is likely what they used on the board to begin with, and lead and leadfree dont typically mix as well.
Thanks for the quick reply...
Something like this?
http://www.oritech.com.au/productDetail.aspx?productID=23244
What sort of iron would be suited? Would any of these suit?
http://www.oritech.com.au/categories.aspx?categoryID=321
Would you say it'd be a difficult process? I've soldered before, but a that was a while ago in high school...
Also the cost of all this equipment will far outweigh the cost of the $3 FPC connector spare!

yes, those should both work fine. ya it is costly for equipment. i have a edsyn iron i use at home and solder i get from work. i would say it can be tricky, i havent seen the connector but im sure its similar to other inline ribbon connectors. remember, short burst soldering, heating it for too long will take the pad off the pcb, and repairing THAT can become very difficult.

Hi guys,
I just have an issue caused by me. When I've opened the phone I've managed to damage one of the components and that cause my vibration motor is not working anymore unfortunately as it is a part of the circuit for it. I'm just about to change it but the problem is I don't know what is the value of that component as I couldn't measure it as it was damaged so much so it wasn't possible to do so.
I would like to ask if is here any1 who can tell me what is the value of that SMD 0402 capacitor ( value in F = farad) - ( see the picture )?
Only problem is if some1 want to check the value it is mean that the capacitor have to be unsolder at 1st to do so. So please, if is here some1 who can do that for me I would really appreciate
Or maybe some1 have the BOM (bill of material) and schemes of HTC One X ? that would help too.
Cheers guys
DAMN! i doubt many people would want to do that mate, bit risky opening it!
Actualy to open the phone is not risky and it is pretty easy.Only thing is to unsolder the cap ad than solder it back that may be tricky and that would need a good SMT experienced person.
I just hope we have some1 like that here (except me lol )

If you get a multimeter and see whether the capacitor is across the power rails if thats the case then more likely it would be a decoupling capacitor that decouples the inductive spikes from the motor when running. I would take a guess that it would be in the order of nanoFarads maybe 100nF.
Even if this component is open circuited that wouldnt stop the motor from working are you sure you haven't put excessive force on the capacitor and it has subsequently levered up the flexible pcb and open circuited a feed i.e. track)from the controller chip that feeds the motor?
For such small work I have a handheld microscope with an inbuilt lcd screen. makes life easier
you need to look more closely in that particular area if theres a minute tear on a corner or 90 degree bend of the flexible mylar pcb
I have checked that under 8x magnifier and I couldn't see any other damage other than that crushed capacitor so I guess it is only that. But to be sure I will check it once again and I look closer on the whole circuit and all the paths
I can't check it at home as I don't have any equip here so I hope I will have some free time at work tomorrow
But thanks fro info, it may help

1st HTC Reply
Thank you for contacting HTC regarding your
My name is Olga and I am a Technical Support Agent for the HTC Written Team.
I understand you are having problems with the vibration on your device and would like to know how much such component would cost.
I am very sorry this has happened and now you are having issues with your device, I have spoke to my supervisor about your query and can confirm that we do not have any rough prices of any of the components for our devices.
The reason for this is that we do not sell the components and use individual parts from different regions. The only thing we can do is book your handset in for repair with us. Please note that if you perform a repair yourself or use a 3rd party repair centre, your warranty with us would be void and in case the phone would need any future repairs, there will be a cost, even if it is a manufacturing fault.

Thank you for your email.
I am afraid we are not able to view online content, I can not view the links.
In regards to the components, we don't have any information regarding the components on our devices as this is something that is only available at the repair centre. Each device has a part number assigned, this lets the repair centre know which component and type exactly is needed for the repair.
I am sorry we are not able to provide further information regarding this as this is not something available for the public/customers. I have double checked this for you with my supervisor but I am afraid the only thing he advises is to have a look through the Internet for more information.

Have you a feed at the motor? Although if it sees the caps open circuit it may just stop the supply anyway.
That's a resistor isn't it? Not a cap.
I haven't tested the circuit with multimeter in any way but it is a capacitor for sure and not resistor.
SMD resistors have the metal contacts only from top-front-bottom side of the component
SMD capacitors have the metal contacts all way round
There are caps on that circuit, some are black and some grey color .
Only problem is that the caps don't have the value marked on the body as some resistors usually have, but normally bigger than 0402 package, so from 0603 and bigger as on the 0402 and 0201 would be really hard to read anyway

Might be worth getting a meter on it then, while setting it to permanently vibrate somehow.. Sure they're apps for that.
Unless your positive it is that cap, then id just pop it out and take a trip to maplins. I've soldered SM parts on phones before, it's fiddly but its possible. They were 50 quid Nokias mind, not 450 quid htcs. Fine iron, and don't get it to hot.
problem is I couldn't test it as the cap was cracked on half so no way to measure
There is no problem to solder/unsolder for me as I'm experience (work in Electronic manufacture business for some time )

If the SMD package is brown in color then it will be a capacitor. if black with no marking then may be a resistor or an inductor. if it is the latter then that would explain why the motor doesn't vibrate.

Surely you understand that HTC can and will not help customers with voiding the warranty of their phone? They support the devices as they are sold and if you decide to open and break the phone yourself you're basically on your own. Helping out with this issue would be to spend time and money to help a customer who has already agreed that no help will be given. Not to sound harsh, but you can't possibly expect any manufacturer to help out with such an issue?
Your best bet would be to contact a repair centre, not HTC. Regenersis, for example, might be able to tell you what component that is.
They only cost Like 50 p for that capacitor

well, not yet as I still haven't found what component is it.The HTC won't help as I posted before and I haven't found any1 who could.
But as someone mentioned here before that it may be a resistor instead of capacitor, so I've risk it and I just tried to shorten that pads and vibrator is working.
Problem is I still don't know what component should be there and I'm afraid that if I leave it with just a link between that may damage the whole circuit in time.
So it looks I have to live without vibration or send it for repair what I would have to pay for it.

My thread has been getting a lot of hits and HTC are monitoring it and possibly all my posts (I may be a little paranoid). Which I am grateful for as it is great to know that HTC are doing their best to fix the issue and I encourage them to follow my thread.
I will try forwarding this thread to Urban Strata (HTC Rep) and politely ask him if he can help. I will also try asking at HTC for you, I need to ring them next week on Tuesday anyway, maybe I can persuade them to help you, I did help make HTC aware of the WiFi issue and how many people where affected by it, maybe they can answer this thread to help us. I feel sorry for you mate and if I can do anything I will
Don't get your hopes up though and continue trying to find a solution yourself.
<EDIT> I've sent you a PM
Many One X owners, including me, has be having from display/screen issues that are quite annoying. And apparently, none has a definite answer as to what the main cause is. hTC has exchanged all those faulty devices, claiming it's a "hardware" issue...while in fact, it's their stupid back covers...i'll explain as we speak.
First, to know what screen/display problem i'm talking about, please refer to this Video.
Few days ago, i got my hands on a "Dead" One X...but i just refused that fact...because it just works! but no screen....screen is always blank....can touch it, go to dealer and make a phone call even. Sometimes the screen turned, sometimes, and it was like in the video, exactly like it.....so what's the problem?!
yesterday, i'll be honest, i got mad at this phone and held it with a tight grip...my finger happened to press just above something...and the screen turned on! worked great in fact! i was astonished! it just worked....but, oops, i turned off screen, then when wanting to turn it back on...blank...
I kept pushing on the back casing of the phone, trying to find the same place that made the screen turn back on...and viola, same place pressed on, screen back on.
Wanna know what's causing all of this?
Here you go:
Click me!
And those connectors Should be in good contact with this on the back cover
Click me too!
But you know, hTC ****ed this one up, just like it does on most devices with connectors on the back cover...*sigh*...like the sensation for example...
So what to do now?
i tried a bunch of things, and almost broke those connectors with a stupid thick aluminum foil on top of them...
also i tried bending them up, but that doesn't help either, as when the cover pushes them down, their shape will change and well...didn't work.
i also tried putting aluminum foil on the metal connectors on the actual cover...didn't help as well!
it seems only pushing on it from outside does the trick!!
i also tried pushing on the connectors together while the back casing is off, didn't work...as it seems there must be a triple connection...board, connectors, and cover...
I think the only solution would be with a new back casing? but...if hTC f****d it up with this one, wouldn't all back casing suck too?? or is this a manufacturing problem that the connectors are just short and won't connect well?!
here are pictures of how the phone turned on magically after pressing over that connector, and another of how the screen gets messed up when the, well, there's not a good connection...Thank you hTC!
Sample 1 Sample 2
Tomorrow i will buy a new back casing and report if that helped me or not.
I only came to this because i have no warranty...if you have warranty, please consider an exchange!
Oh, and finally, i was able to get into bootloader, first time i saw that screen! always has been blank!...pushing on the connector also did the trick.
Finally!
Soooo...comments?
If anyone has an idea on how to make the back casing come in better contact with those connectors, please let me know.
UPDATE
Hmm, why did you put this into Q&A?
what? in a bad mood and wanna bash me?
where should i put it then? as people with such problem would come ask here, am i right?
EDIT: lol, it's all good now ^^

Well nah, would post it into General , as this was more like a guide. I wasn't bashing.. and not in a bad mood... If anything I bumped your thread up...
Also wanted to say that those contacts and that case seems to be f..cked up in general. As next to those you have the WIFI ones which in another thread, thats in General is shown how to fix...
My first comment was a compliment and you could clearly see I was smiling as I am on my avatar smiling. No reason to get defensive...

oh well...also WIFI connectors are bad?...no wonder SIII is flying and hTC is dying...
anyway, maybe a moderator can take this thread to the general forum, thanks for pointing those things out!
and sorry i seemed mean, but many, really, many users have nothing better to do but nag...trolls
thanks ^^
Soldering would fix this!
putting two round solders on the gold plates of the back cover. i will try that tomorrow. but i fear they would squash the connectors on the board? as that's what happened when i used two tiny balls of aluminum foil....one connector got squashed by it and i had to push it back up and play with it to make it look normal again.....hmmmm

Moved to general forum hope youll fix it bro...
So it is a hardware fault,would never guess that...in the general forum you have a topic with the name "wifi fault" give a look on that

*nods* already took a look at that
will try the soldering...or connecting a wire between both connectors...one of those should work

waw another fellow citizen
so before we go ahead and go
doooom gloooom htcccc suxxxxxxx
lets first affirm tons of people have no problems with their wifi and their screens
so yes those connectors issues whether screen or wifi are another forum of a manufacturing defect, things might not be perfectly aligned and hence the issue
the flickering issue your thread title suggests finding the source of, isnt related to this, 90% of the corruption we saw out of box on the HOX turned out to be software including the back-light flicker which HTC fixed by readjusting the LCD voltage
moving on to your question a new back cover might very well fix it unless the misalignment is on the board
but im wondering why is this pin related to the screen to begin with? the Sensation didn't have such a pin you could remove the back cover and the screen kept operating, also the disassemble photos that were posted for the HOX showed the board and screen running perfectly without the back cover
as for the stupid copper foil, make sure you don't loose it unless you are planning to make a bomb its added to distribute Tegra3 heat

Before you do that, please check the WIFI thread. There was already one member that described that soldering or adding a wire might be possibly harmful in the long run.
Changing the electricity stuff, how its called, the resistance or something (for the antenna though)
I'm having the same damn issue (check the picture) and thanks to Arabology for the well explanation on the problem. what I did was to send my phone to the service center and they told me it will take 3 working days (today was just the 1st day) for the technician to diagnose the fault and decide whether to replace the device or to repair it.
given that its a well known defect - should I just demand an exchange for a new device just incase if they revert that they repaired my phone? because I am sure the chances for the problem to reoccur is high.
Also just so you know I purchased this phone only about 3 months ago in HTC roadshow launch of OneX in Malaysia. HTC needs to come out with really quality products otherwise they will loose all their customers to samsung & apple (I believe they already lost major % of their loyal customers to their rivals)
oh well hope to get a good news soon. will keep u guys posted.
Update:
well, My One X is just cursed, few days ago it feel off my hand and the screen got cracked. now i'm waiting for my local repair station to get hold of a One X digitizer.
ALSO, HUGE NEWS, seems i was wrong. it's not the connectors. it's the whole part where there is a copper kinda sheath over it...i guess that's where are the cores are plus the Nvidia Tegra chip??! turned out, when i push there, that the screen lights up. at first i thought it's the connector, coz that's the most reasonable right?
what could be wrong under that? well, that place can be taken off, there's a metal housing that can be lifted off....idk, nothing seems wrong there...but seriously, just a slight push lights up the screen! so now i'm using the oldest trick in the book, i put a wrapped paper at the back of the casing, just where it will push over the place i talked about, and now screen is always on....just this small push does the job!! no more flickering!
i repeat, it's not the connector nor the back casing.......only God and hTC knows what's going on...
i did further investigations and tried to relate the "push" to any connections that could be on the board from the other side, but after disassembling the phone, there does't seem to be anything on the other side of the board that needs that certain force to help the screen to light up....idk, this just boggles the mind.
...anyone has any clue?!?
BTW, phone is working great even with the cracked screen, playing Dark Meadow just fine

i say you should demand an exchange. hopefully the device they'll give will be of a different tier of products that doesn't have that silly, unknown problem.
also, i'm pretty well sure that they won't repair your device. as i read many users regarding this issue, all of them got an exchange......seems pretty messed up. and i doubt my paper trick will hold long before this issue comes back

now that i have a paper inside my back casing, i can see that my WIFI connection is not at it's best, because of the extra space it took. so i'll most probably solder all the connectors

there was some guy, who posted a youtube video of when he pushed a certain area of his screen (the front part), it would switch off!
It only did it when pushed in that area, it was literally like a second power button.
Sorry I don't know exactly what it was, just the fact that somebody else had a similar problem!
HTC repaired my phone as the screen was faulty, it had a yellow tint, when i sent it for repair it did have screen flickering, ever since its come back, with a new screen, i rooted it and also put in the NEW ARHD rom, 2.05.2 base or something, it has stopped flickering :fingers-crossed:

Finally found someone with the exact same problem. I haven't been able to use my hox properly for weeks. Think I need to be sending back to HTC
Sent from my X10i using XDA
Finally I've got my OneX replaced with a new unit.:laugh: Hoping this will not have any sort of hardware faulty anymore.
interestingly. while waiting for my turn in the service center, I was just talking to a guy sitting and waiting beside me who came to report a problem with his OneX
and apparently its his 4th time visit to the service center. And all his previous 3 visits ended up with his OneX getting replaced each time....and each time with a different hardware issue (screen flickering / dead pixels / color faulty). Oh man....I thought the OneX was the best quality product from HTC.
and now I'm having a slight regret that I shud have just waited for another 2 more months and bought the SIII instead. God knows what other problems my OneX is going to come up with.

Probably what's referred to as a dry joint or some other connection not connecting very well, not uncommon in electronics.
You need to get it repaired or replaced, simple as that. If it is a dry joint under one of the chips that use a ball grid array of solder points, you will never be able to sort that out yourself and it would be scrapped more than likely rather than a repair attempted for such a fault. To repair, it would need to go into a special over to heat it enough to melt the solder under the chip. Exerting pressure will just eventually make things worse as you can end up fracturing more of the soldered connections as there is little give to resist flexing.
