Hello, I saw that someone else asked a similiar question before but they did not word the question correctly and got little help.
On my HTC EVO logic board, there's three tan "ports" (I don't know what they are actually called). One for the front camera, one for the LCD, and one for the front panel.
While walking home one day, my screen started showing a dark spot. The spot got bigger, and I decided to take apart my phone (something I'd done before a few times) and try to clean things up. I put everything back together, and the LCD would not come on. After numerous tries, I finally decided the LCD was damaged. As I went back in the phone, I saw that regardless of whether you flipped the black tab on top of the LCD tan 'port' back or forward, the cable was capable of being pulled out, e.g., it was not secure. At the time, I thought nothing of it, but now that my new LCD should be here, I'm worried.
Is my LCD not working because the 'port' is broken? If so, what can I do to repair it? (I heard it is very difficult). I'm worried, because I paid a lot to buy a new LCD and will be unable to send it back.

Also, my front panel cable never sits 'perfectly'..that is, I have to connect everything else first, and then try my best with the front panel. The tape does not stay down flat completely.
These sorts of connectors can be fixed,but there is quite a bit of skill involved. Upload a picture and I can tell you better how hard it is. What I can tell you is that you probably cant do it yourself. I base this on the fact that those who have the necesesary skils will instantly know its going to be a pain. In fact,its easy to screw it up ,and sometimes you do,even if you DO know what your doing. Since I dont want to take my phone apart,Ill need to see a picture of it before I can tell you anything more. One thing to keep in mind is that sometimes the ribbon cable CAN be pulled out anyway,and is making good contact and there is some other problem. If you have not installed the new LCD,install it and see if it all works. If so,your good to go. As a general rule,the connectors are delicate and its not a good idea to pull them out. In fact,dont disconnect them if you dont have to. They have a limited number of connect/disconects they can take and they are very easy to break.

Well, I don't really have a means of taking a quality photo except with my computer webcam but I'll try in a second. I can't really show you because there isn't much to see. The little black bar that flips up and down to 'lock' the port is ineffective; the cable can be pulled out regardless. I know I can't fix the port/connector by myself, so I'm hoping that's not the issue. You have given me a lot of hope though. The new LCD should be here by Wednesday at the latest, so I'll be able to test it then.
Does my front panel affect the LCD? Since I dropped my phone on the corner, even with a new panel it does not sit 'perfectly'. I don't think they're related though.

I dont think so. I bet your ok. Just dont keep playing with the connector. I know,Ive done it. I sit there messing with it,wondering,is it broken? Is it good? Then the little black peice comes off in your hand or the plastic breaks and "well its sure broken now!" Remember,that little latch does not so much hold the cable in place as hold the cable against the contacts,if its making contact,its good to go.
Hi, all. The new LCD I receieved did not work. There are very minor differences in the two; such as some type of blue gunk on the silver part of the LCD, the connector is more of a dark orange on the new one while the original is a yellow-orange, etc. Also, again, the connector does not 100% fit in the slot. It goes in, but a small corner sticks out a bit and you have to either hold it in or clip it in [which I can't, because the black clip is broken].
The only possibilities I can think of are
A] Because the little black thing is damaged, no LCD will work in it. Therefore I need a new phone.
B] The LCD does not work.
C] The LCD is the wrong size.
At this point I want to just give up and get a new phone, which is very heart-wrenching because I love my EVO and I doubt I can afford the only other phone I like, the Samsung Galaxy S II Epic Touch 4G.
Is anyone able to identify what connector is used on this phone for the LCD? I broke a pin on the connector while trying to repair a cracked screen. I would like to buy it and re-solder it on to fix the phone.
Can someone link the correct connector maybe from digikey.com?
Broken latch
I too have a problem with the connector... the plastic part that connects the ribbon cable to the main board has broken. There must be a place to buy these tiny plastic latches... does anyone know? Your assistance will be greatly appreciated!
Mac-
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.

Hi guys,
I had my Gnex for more than a year and thought I was one of the lucky ones without USB wake problems. That is, the USB port thinks it's being plugged in or unplugged causing the screen to turn on and subsequently kill your battery. Unfortunately, I started noticing the phone turn on occasionally. Then, it progressively got worse over the course of about 6 weeks to the point where it had to be plugged in several times a day.
One of the tricks that helped in the short-term was to move nudge/coax the contacts in the port in an upward direction. So, with your phone facing up insert something very thin (ideally plastic or paper-based) between the bottom of the port housing and the nipple thing that sticks out that has all the copper contacts on it. There is almost zero room, so you'll need to search for a suitable tool. Once you put a bit of pressure in an upward direction for a few moments you'll find your phone doesn't wake up at all, or as much. Unfortunately, that only helped for a while.
I'm not sure what the cause of problem is. I hypothesize that corrosion occurred when I left my phone in the washroom while I had a steamy shower every day for a few months, but who knows.
I found no suitable software workarounds.
I didn't want to junk the phone, so I ordered a replacement part for only $5.99 + shipping. You can find the part here: Witrigs. Given the price, I suggest you order two. I don't recall the shipping, but it wasn't expensive. Delivery was around 7 days to Canada (from Hong Kong). Website is definitely legit. Maybe add some other parts to your order, if you feel so inclined.
The install wasn't too bad. I'm a dummy and thought I would skip steps that I didn't think were necessary, like removing my sim card. Don't skip steps! The iFixit instructions I followed don't seem to be around anymore. There are guides on YouTube etc that are helpful but they make it look way too easy. Expect to struggle with removal of the screen from the casing. Be careful when you're jamming around into the edges because there are many delicate sensors and buttons which can be broken. Credit cards work well. Overall it's safe, just use your common sense.
Overall, the replacement wasn't too bad. Unfortunately, the replacement part was IDENTICAL to the outgoing port. I was hoping there was a revision, but no dice. I'm glad I bought the second replacement port, just in case I have the same problem in the future.
Anyways, I did this a few months ago and am trying to remember the best I can. I hope this might help somebody.

Thanks for sharing your experience,MO and advices; I can remember several that had the issue and some fix it by just working around the usb port with a suitable tool, others tried to replace the part without sucess, and others with sucess;
Offtopic: I think this thread belongs in General, no question here. Reported.
Replaced my charging port + flex board yesterday. Ordered the replacement from Aliexpress for $3.something and free shipping! Took around 2 weeks to reach me, but the part works perfectly and you can get faster delivery by paying for express delivery.
The iFixit guide is still there:
1. http://www.ifixit.com/Teardown/Samsung+Galaxy+Nexus+Teardown/7182/1
2. http://www.ifixit.com/Guide/Repairi...+LTE)+Micro+USB+Charge+Port+&+Main+Mic/9641/1
Also looked at various youtube videos before I finally undertook the replacement.
Cheers to everyone who fixed their own phones!!
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 guys, I have several problems with my HU. It have some bad contact over the MCU board and cant find it.
I trying putting little tips of cork under the board and I had relative success but on the road.. still fails..
the symptoms are related to TFT in first place, white screen and some times suddenly reboot.
I can hear a sound like fried when is in a bad contact. If I press over the board, it rects, but when release the pressure, bad again.
It make me nuts.
Im thinking to do a REFOUND in the oven... I just try everything.. no solder points damage at simple view..
Please, if any body here have deep electronics skill, let me know.. need some help.
Thanks

If you haven't ready, try obtaining one from your seller. If seller won't, check for a similar unit from another reseller.
I got my replacement from Xtrons, you've just got to figure out who to contact. Also Hotaudio, their guy is brilliant.
