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...

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

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.

OK, I've replaced the micro-usb socket last month, and I saw a weird part of the device, that was look like an antenna.
it's weird plastic which covered by flexible PCB with some traces and net without parts.
by mistake for finding an external antenna for our Galaxy I found out this link on ebay
http://www.ebay.com/itm/New-GPS-Sig...320146?pt=PDA_Accessories&hash=item43b3adcad2
this is the same part I found in my galaxy, just in my galaxy it was white (I9000T January 2011), I looked in alternate device and it was black and less unstable (moving).
maybe this can help us with our GPS receiving?
I've ruined my GPS part when I tried to close the back cover of the device with power, but the traces was untouched, and the GPS working regular (bad but you know).
how it is mounted??
It's just staying there touching the traces

Sorry to bump an old, old thread but I was searching for help with poor GPS and I now know that the thing the OP is talking about is actually the GSM antenna which is located in the bottom of the housing - near the mic.
If you want to replace the GPS antenna, well, its not much more than a sticker and you should just buy a replacement middle chassis because it will already have one (along with wifi/bt antenna)
Weird thing is that you'll find lots of people selling that item as a GPS antenna - it definitely isn't though.
Hey guys! my name is chris, im a Mobile repair tech
I have my own company its 777 Mobile Specialists
So heres the problem i have, a customer has brought me a galaxy s3 t999 with the complaint that its not responding to touch anymore.
Initially i thought it was the Digitzer, and i told her the screen was a pretty expensive piece of hardware, so after some more testing, i put another logic board in with her screen and whaddya know? it works perfect, i tried multiple logic boards, all work with that screen, however hers does not.
Now with that being said, i did notice that there was some corrosion inside, it looks like some water had gotten into the phone, she speaks spanish and i dont so it was very hard to communicate with her in the beginning so i didnt get the actual cause of the damage.
Could you guys tell me possible what area of the board controls touch activeness and response? if need be i have many extra boards and i can take out what ever parts i need if found.
Thank you guys. ive been a member for a while but have just never posted much, but you guys are amazing, ive been using the roms here for quite a while and tutorials are awesome!
Thanks for reading!
It's been about a year since I worked on any GS3 internally, but if I remember correctly, you'll find the connector to the screen + digitizer on the lower left face of the screen off to the side. That should lead to the main board. If you look on ifixit, or even maybe YouTube, they have videos of GS3 disassembly that explains the components as they go along.
Sent from my SGH-T999 using XDA Premium HD app
Well actually i have it apart, and ive taken many apart, what i was basically asking is if anyone knows the actual location of the chip or resistor that controls the actual touch response to the digitizer, or even which pin on the connector is involved so that i can trace it back, because ive examined the board very thorougly and i dont see anything damaged or burned, but you know which these things, you cant tell that way most of the time, so i was going to do some multimeter tests and see what i get if i can locate the damn thing.
Anywho, thanks for your reply, but if anyone knows exactly what im looking for id be very grateful
Does the Teardown help ?
Damn, ive had no luck, the phone was water damaged, the LCD works perfectly fine wi th any other logic board and this logic board does the same exact thing with any other LCD, can anyone help
Anyone have any idea? Q.Q
Hello
I just replaced the screen on my nexus and now the touch won't work. It doesn't respond to anything, maybe you guys have some ideeas . Maybe you can see something wrong in the photos I've attached (sorry for potato quality).

Did you replace the combo or just the touchscreen? Did you test it before when everything hooked up before taping it to the bezel? What kind of tape did you use? You may want to post a higher resolution thumb of the area where the ribbons connect to the board.

Nope I didn't test it but I put some tape that is easy to remove so i just removed it checked all connections, nothing seems wrong. I attached some new photos (best quality i can get right now). Also I replaced the full combo lcd+touch. Thanks for the reply.

Nothing looks out of the ordinary in those pics, though I don't see how one can replace the combo without removing the boards. Can you explain that as some step in the procedure might cause this. Instead of guessing too much, let's take one thing at a time.

Any revision number on the digitizer? I know that there are different revisions of the daughter board and that if your tablet came with a 1.3 board and you replaced it with a 1.4 board the touch would not work, but I don't know if it is the same for the touch screen

I looked at the clip, and it seems ok, except the emi tape hanging from the frame would not stick to the back of the lcd that way. I don't know that it should make a difference since yours is totally unresponsive to any touch. Same case with the missing one going on top of the touchscreen connectors.
There have been cases with other Asus models where you'd need to re-flash the touch firmware before it works. If the daughter board had been working before you replaced the screen, you can either (1) re-flash a stock rom (444 to be sure) using fastboot, or (2) if you're on custom Kitkat (I don't know about Lollipop), re-flash said firmware following the instructions HERE. Remember you have to have one of those kernels mentioned therein installed for the firmware to stick.
I don't know that the touchscreen version should make a difference since they all use the same rom wih the same touch firmware embedded. Unless the rom contains many versions that would automatically select one fitting your hardware version, in which case you should flash the official Kitkat.
Failing all the above, I'd conclude the touchscreen itself is bad. It's a rare occurrence, but has been known to happen. If you bought it from a reputable seller, you should be able to get a replacement. Don't hesitate to ask if something is unclear. Good luck.
I have the same problem. I bought two digitizers and lcd, and both times the problem is the same. I checked for a rev number on the digitizer, but with no luck. The tape I used was M3 300LSE. Already flashed 4.4.4 stock firmware on Flo kernel, but it didn't work.
I can't believe I bought TWO broken digitizers from two different sellers. I will retry the flash...
I tried to see if there is any recognizable serial number on digitizer, and I explain what I found here: http://forum.xda-developers.com/nex...xus-7-2013-touch-screen-unresponsive-t3035124
I'm sorry I'm posting about same issue in two different threads, i did open the other one cause I didn't see this one...
