[Q] HELP! White lines on black screen HTC Desire CM7 - Desire Q&A, Help & Troubleshooting

A few days ago I succesfully (at least I thought so..) flashed my Desire to Cyanogenmod 7 using Amon-ra and it worked perfectly, until today out of nowhere my screen is black with a couple of white lines from top to bottom. One minute it worked as normal, and a couple of minutes later when I pressed the top button to unlock it, the screen was all weird. The touch functions of the screen seem to work as normal, I can unlock the screen, shut it down, power it up, enter my pin etc (blindly) but I see only the vertical lines so it's hard to check what's going on. I do see that the lines "move" when something changes on the screen, like when I unlock it, I see that the screen does react on it, but only some lines appear, move or disappear. For the rest, the sound works as normal when I turn op the volume, as does the vibrating.
I have a PVT4 S-on (thats all I remember) if it makes any difference.
Picture is from a camera, not a screenshot. Looks a bit yellow or so but the background is black, and the lines are white.
Does anyone know what it caused and what I can do to fix it? Maybe reset it or reflash it someway?
Many thanks in advance!!

Where's the picture?

You might want to give HTC a ring.

Request from puntchiel, a picture of his mobile phone:

Hm I forgot the picture, my friend len posted a link for me, for Im not yet able to do that cauz Im a nub
Thx len!

Yeh, send it to HTC or your carrier. It looks so ****ed

Well, sending it back and profiting from my insurance is my last option cuz I wont have it back for at least a month. Does anyone know what it could have caused or what could be a way to solve this highly annoying thing? I can't imagine that it is a hardware problem that occured this sudden... And the screen is reacting to my input but it only shows the frikkin lines! So I hope that it is a software problem. I just have no idea how to solve it, so thats why I'm asking the pro's on this forum

And btw, if I'm sending it back I need to make sure that they don't find out of the custom software on my device. That leaves me only two options I quess, fixing it or completely smashing it... So if someone at least knows how to use a RUU or something via my PC (without having to use the screen of my desire), your help is very much appreciated!!!

Ohh yeah thats helpful; i am sure he did not think to contact htc himself

That picture recalls bad experience with my ex Nokia 5800xm. I had to replace display.
Maybe it is not same case but it looks same.

I have exactly the same problem, flashed cm7 on my desire a few months ago.
Worked all fine.
Then yesterday all of a sudden i had a black screen with white lines.
Maybe you, puntchiel, have found any sollution?

I'm sorry Hanswurst, I had my ensurance company pick up my device and they replaced the screen, so I asume it was a hardware problem. I wish I could help you buddy. Good luck with it!

Help my phone is dying!!!

I got my hermes from my friend, (HTC X01HT), she didnt want it because she dropped it and the ringer didnt work. it had only gotten unplugged, so i opened it, plugged it in, and had an awesome phone.
I dont think this is normal, but from the time she gave it to me, the screen made an awful highpitched ringing noise, (very uni-directional, it was weird).
Anyways...
now, the screen is just white. for a little while i could get the screen back, just by opening and closing the slider and hitting the power button a couple times.
Sometimes the today would display, then it would jarble up a little bit then fade to white, but i cant even get it to do that anymore.
Anyone else seen this issue? i'd hate to get rid of a perfectly awesome phone.
Thanks!
(also, if someone could post a picture of the device locked screen, where you have to enter a PIN to use the phone, that would be great, im trying to get into the phone with activesync, but its locked, and i dont know where to push the buttons.)
thanks!

Looks like the screen is unplugged, really. Maybe you need to disassemble further, like http://www.pdacenter.ru/razborka/razbor_hermes/ shows?
keep in mind, it worked fine for almost three weeks before the screen issue started... but i will try that when i get my hands on a small flathead again.
There's a whitescreen & D-Pad failure issue that can be caused by many things, including DROPPING the phone.
I wrote a guide about it which seems to be quite successful for many people.
http://forum.xda-developers.com/showthread.php?t=321163
so after trying a hard-reset, (which somehow displayed on teh screen), and clicking no, i was able to get the screen back... only this time with the moved screen problem, wrapping around at the top about 1mm.... and the buttons didnt work.
i tried your guide, but now im stuck at the white screen again... :/

Blank screen

I have been using CRC 12.11 for a while. A strange problem started all of a sudden. My screen went white although it is working. Soft reset didn't solve the problem. Hard reset solved the problem for a while and then it came back. I noticed this at the time it happens. While everything is fine, the screen fades out, a few lines like scratches appear and then the screen stays white. I hear system sounds, the phone rings but no display. What has caused this?
I flashed another ROM but when my phone restarted it was still white. I hard reset and now I am waiting. If it reappears, it means it is a hardware problem right?

I had this same weird issue once on my rom, i think it's because of the Big storage bug.. Flashed OEM rom and went away.. only saw it once!
I reflushed several ROMs that I used to have before without problems and still have the same. I can't install OEM, I think it's because of the bootloader version but I don't remember exactly the procedure to correct this and I don't know if it's worth the effort in downgrading to OEM.
Another thing I just noticed is that the screen is not aligned in the center. There is a small gap on top of the screen as if the image has moved downwards. Maybe this is the cause of the problem. Noone had similar issue? I don't believe it has to do with big storage because I have been using it fot a while and this never happened before, not even once.
Any ideas will be apreciated as my only choice right now is to buy a new phone.
same thing
i´ve been looking around and some people say is because the magnet in the pouches, affect in some way to the screen ribbon or something like that.
that is a common problem with the hermes, if u search the forum u'll find a couple of threads like this.
it's a hardware problem, next symptoms will be the green/red buttons and d-pad stoping to work
I know theres a few links in the FAQ about the white screen issue, its fixable in some cases.
problem solved!!!
i just took it apart, one of the ribbons which connect the green and red buttons was kindda folded also the connectors , so i just blow some compress air and tried to unfold the ribbon, put it back together and voila! like new. Just be carefull cause it´s like fragil.
same exact problem word for word
The same exact thing happened to my hermes. I guess I can attempt to put mechanical skills to work and fix this problem.

black screen phone still works - Help?

Ok..i searched the forums and didnt see the problem i have ran into so any help is appreciated.
I get a black screen but the phone starts up and runs fine..i can fiddle with it and make calls etc..the screen is responsive to touches..just black entirely. But...on occasion it will decide to show the start up Touch Pro screen and stay there..and on occasion i can get the hspl screen to show up..but its very infrequently and seems random.
I have reinsalled the hardspl..i have reinstalled the ROM several times..i have task29ed it..still its working but the screen is black.
Im assuming there is nothing wrong with the screen as it does work fine on occasion (just never gets past the opening screen)..so any suggestions?? Please help.
Let's try this
Did you try to go back to the original ROM, or a factory rest - check the manual for that.
Also, try the shortcut in the manual to get to the boot screen.
Good luck...
Black Screen
It is your light sensor, either it is malfunctioning or it has driver corruption problems, probably the light sensor. I posted a fix a couple of days ago that cured my tilt 2 of essentially same problem. You must remove all reference to polling light sensor, ie, backlight automatic, keyboard backlight and phone backlight off on calls. Review my earlier post for details

HTC One X Screen won't turn on, touchscreen still work???

I have been using the HOX for over 2 months now but this morning my phone display suddenly doesn't turn on even the backlight key still on and touchscreen still work ( when I sweep my finger up the unlock sound still play, and I can even adjust the volume of the phone, etc... ) I have no ideas if this is a software or hardware problem and how to solve it, I'm still on Stock Rom, Stock Kernel,... Please help me
try to reboot pressing power button for 10 seconds, if it'll not work, it can be hardware problem, as i understood you haven't unlocked it, so you can send it to htc and they will repair it, or if you can, you can change it by yourself,
have you tried starting in bootloader and factory resetting?

Yeah I tried to reset the phone, ai first it worked. But when I turn the screen off and doesn't use it for a few minutes, the problem is back again, It's really odd, I have heard about lots of HOX Screen problem but I haven't seen this one before
So the screen works in bootloader?

Sometimes it does, sometimes it doesn't. Really weird, it feels like the phone has woke up but the display still "think" that it still in standby mode
Hardware fault for sure.
Same Problem
Hey, ive been using my international HTC One X for about two months too now and there have been no problems. ever since the update to 4.0.3 ive been facing exactly the same problem. The screen does not turn on a lot of the time but the touch is active. Have you found any solution to it?
It would be great if you could help me out.
Thanks

I have the same problem now. Using it completely stock, the screen doesn't turn on. Well.... Except for the times I visit the Vodafone shop to get it fixed....
Their first reaction was a defect in the screen, so they ordered a new one. I brought it yesterday again and it is now in for repair.
I don't know if this will solve the problem. How did they fix yours?

I get my HOX fixed last week and I worked normally again. But after 2-3 days, the problem is back again. I contact HTC and they said they even replaced my MOTHERBOARD and Screen. Wtf is happening???

hey guys
I had this problem a month ago, i know its frustrating.
anyway the only solution is factory rest from boot loader and flash RUU (worked for me)
the first time i had it, i did a factory reset, all my pics music were gone, phone went back to normal( stock, locked)
after a day the problem appeared again, second rest.
flashed RUU and the problem is gone. thanks god i have been using my HOX about a month science that problem and every thing is working great.
im sure its a software issue and I recommend every one to back up their files(pics,music)
just flash RUU and good luck
Lol, exactly the issue I had recently had with mine. Sent it backto htc, let's see what they would do about it.

My colleque has the same issue with his One X.
It started with suddenly everything on his screen looking "zoomed in", so everything double size, looking ugly as a mofo, and not usable. After locking the sceen and unlocking again, it was fine.
Monday suddenly also screen didn't want to turn on anymore. Did the hard reboot for him, and it worked again... Untill he locked his screen and wanted to unlock, same issue.
Also, that time when doing the hard reboot, screen didn't turn on at all. Did another one, and worked again.
He's now sent it in for repair, this definately sounds like ahrdware issue, even full reset through bootloader didn't help.

Yup, exactly the same problem I'm having, I sent it to HTC, they said they fixed it by replacing the motherboard, but now it is happening again, I will have to send to HTC again.
This just happened to my phone... Has anyone else solved it? Is reset and flashing RUU the solution?

I have the same problem right now.
It started last week when I was using Flipboard and suddenly everything started zooming in and stuff (same as mhulsegge above). It was resolved by locking my screen and unlocking it.
Last night, i've been getting the black screen when I try to unlock my phone. The touchscreen still works but the screen is just blank. It turns on if I keep locking and unlocking, but it's getting annoying.
My phone is an international One X (duh) bought in Hong Kong and I'm currently living in Canada so it would not be possible to send it back for repairs. Plus my phone is rooted and I am currently using the latest MIUI ROM (2.9.21). I have been using an app called "Sleep" which tracks your sleeping patterns. It requires you to place your screen face down on your bed when you sleep and the accelerometer will track your sleeping patterns and wake you up at the most optimal time. I assume that for the accelerometer to work the screen has to be on, so I am wondering if this can be a screen malfunction (overheat or overuse) problem since the screen has been on for so long (every night when i sleep for around a month).
Since sending it back is out of the question for me because of where I am living right now and I have voided my warranty, I am downloading other ROMs as we speak and seeing if it is a problem with my ROM. I will keep you guys posted.
-edit- I have tried factory reset and reinstalling my ROM (with a full wipe). Still doesn't work.
It´s probably not your rom since I use CM10 hand have the same problem and others have even been running stock and had this problem. The only one who seems to have solved this (at least in this thread) flashed RUU, so guess I´ll go try that now...
Would be great to hear if anyone else has solved it, and how!
edit: This has to be a hardware problem, if I push on the screen it starts working! Its like something is loose, and when i press on the screen it gets connected again.

Good tip, but I tried a gentle two-fingered push (zoom pinch) and the backlight turned itself on with very little pressure, certainly not enough to flex the screen. I believe that it is a state issue related to zoom, but will try again and report if the issue returns.
Screen black after replacement lcd display unit
Hi,
My HOX touchscreen was broken, the touch and everything was still working. I ordered a replacement lcd display Unit and replaced the complete display and touch. After replacement the screen is completely black but the phone still works. The touch buttons on the bottom still work and i can use the volume buttons. I replaced the lcd display unit very carefully and i am sure nothing is broken etc. So the touch is working but the screen is black. I tried 2 display units and both show me a black screen.
Does anyone know how to solve this problem? Did i forget to do something during the replacement?
Please, i need some help with this issue.
OneX has too much issue with Screen . WTF with HTC?

[Q] Wildfire S screen sometimes refuses to turn on (Standard ROM)

Hi guys I wonder if you can help me. My friend broke his Wildfire S screen and asked me if I could fix it. I got a new glass / digitiser from eBay and replaced the screen. All look fine to me so I took it back to him.
It seems since replacing the screen the phone sometimes refuses to wake up when clicking the lock button, or when an inbound call arrives. The phone rings but there is no sign of life other than the ringing noise. If you then plug in the charger the screen will turn on and you can use the phone as normal. I've tried a factory reset on it but nothing seems to help.
I haven't replaced the LCD just the glass/digitiser, and can't think of a reason in doing so would break other functions of the phone. Can anyone help or suggest what might be the problem here? I'm a competent repairer and have replaced the screens on many Laptops, iPhone's and iPad's but this is my first encounter with a HTC.
I believe it is a stock ROM branded O2 - Details from the phone are ...
Android Version - 2.3.5
HTC Sense Version - 2.1
Software Number - 2.26.206.1
Kind Regards

i have a similar problem,
I have replaced the digitizer but the phone doesnt start. I press the lock buttom and the phone vibrates, but the screen is black, nothing apears...
What can i do?
I would like to know...
I've no idea been trying for ages, I'd like to try a newer ROM but can't get the phone in to S-OFF.
I've done the whole HTC Dev thing and unlocked the boot loader etc, but can't find a stock rom / RUU that will flash to it.
And here's me thinking this site was going to be helpful and full of people who knew what they were talking about!
