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.
Hi

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.

i tried searching the forum but couldnt find any info on it.
the external speaker on the htc one x stopped working but if you tap the back casing the speaker works for few hours and then the problem comes back again. i tried flashing a new rom it works for a bit and and then had the same problem again. is there any suggestions what could be done to solve this issue?
Maybe you got a defected HOX ??

found the fix. it was the contacts that connects the speaker module to the board, may be the contacts( the same type of pins that caused the wifi issue) on my HOX got pressed too much i guess, probably going to solder the pins when i get home as of now have it taped up for the testing
i had the same problem when i openned my HOX, after closing, back button led and speaker didn't work, i disassembled and reassembled again and it works, so watch out if you'll open it!
I see ... Hope you get it fixed then
soldered all four connection, did a test didnt work so i played with the speaker connection a bit and it worked. i guess the speaker had a loose connection or something as of now placed a bit of masking tape and closed the housing. working so far now. i guess the problem is with the chip where speaker is plugged
Had the exact same problem, although it degraded to the point that tapping the grille only brought sound back for a second in the end.
Got HTC to repair it along with the wifi.

Hello guys, after screwing up my phone I'm using my tablet a lot more. So i'm experiencing some problems. The screen problems increase when i use the tablet more often, but i don't have this phantom touch problems it's actually the screen stop working. It just stays on lock screen and me unable to unlock it, i restart the tablet and still doesn't work. However the strange part is that when i hit the back of the tablet in something it immediately starts to work??? I know about the N7 touch screen issues, but i thought they were software based? But mine looks like it's hardware problem? Can you explain me and help me? Thanks.
Can somebody answer me??

If it's hardware, it's most likely, though not exclusively, the cable connections. You need to take the back cover off, and reseat them one by one. Takes a little work because there are 3 cables, one with 2 prongs. Reseat all of them if you can since you don't really know which one caused the problem.
Warranty?
Ok i saw some videos that it may be replacing the screen cables just as you said, but i have warranty. What to do? If i take it to warranty center it's most likely it will work there at the moment? It stops in random times.. What to do?
Removing the back without voiding the warranty is very simple but make sure that you will wear some sort of protective gloves and not touch any copper foil at all ( or you end up with finger prints.. ). Simply reattach the touchscreen connector cable only and you´re good to go.

Thanks for the info. Actually i can fix it easly not by hitting, but just by pressing the back cover. I saw where the cables are in a video and can permanently fix it by putting something between the back and the cables to keep thwm in place. And when i press they just go in place. For now i will just press it when needed. If the problem increases i will open and reattach all cables in place. Thanks for answers.
I have a KGL unit with RK3188 quad core CPU and 1024x600 screen.
I was working with custom ROM (made by Malaysk)
I didn't update anything recently.
Suddenly that morning, the screen is black.
I am able to hear the radio, and Bluetooth calls are being transferred through the unit, but the screen is totally black, zip, nada, nothing at all.
Any ideas what could get wrong?
I've had this happen before also. Do you see any boot logo at all?

I see nothing at all. Black all over the way.No logo

Did you tried to enter the recovery or it is shows black screen also?
If yes, maybe your display panel is wrong. If you seller ignore your messages, try to check your panel's contact to the board.
Check to see if you can get into recovery. If screen works, turn off lights when in rom. I had issue with auto brightness which was too low. Only way I could fix was to wipe and reinstall and turn off auto brightness.
Just updating... it was a hardware problem.
Flat cable problem + certain transistor.
Thanks for your comments.

The buttons were OK, I was able to listen to radio, switch stations (via the wheel control), and even BT calls went through.
That made me guess that this is a hardware problem, and not software.
and no matter what you did you never got video ? Ive got this same problem but after a hard reset Ill get the video back sometimes.

Actually, I even didn't try to hard reset the unit.
Took it from my technician, and it was working, without any hard reset.
To be precise, I'm going to visit him again tomorrow, since the colors on the screen are a bit on the green side, and a bit smeared.
Not a disaster, but not as it should be.
I guess one of the flat cables inside the unit, is not in its place.

I had a similar issue - would lose screen output, it would go either black or white. Touch screen would still work, and radio/BT as well.
Then I'd disconnect the flat cable and reattach it, and it would work for a couple of days. Final solution (it seems) was to hold the flat cable with tape/hot glue!
Thank you, mine just went out again, it was fine for a month or so after reseating all the ribbon cables in the ZIF connectors, I'll do it again tomorrow and try securing them with some tape.
