Hi,
I got this weird problem and im not sure is this a hardware problem or not. For example. when using menus with white background, the background goes partly blue. Sometimes the graphic error is only blue lines in some part of the white background.
but when checking one option in same menu the background turns normal or atleast there is some change in the background. So these errors reacts only when changing options. And theyre always in the same position when going the same menu.
Also when using camera. the view is messed up a bit. there is a clear line somewhere in the picture when going dark to bright. With my english its hard to explain especially when i dont have any idea what is causing this problem.
Below are two attachments that explains the problem much clearer than i can write:

And before you ask. Yes, it has dropped and i have replaced the glass. But i got it with broken glass so i dont know was it like this before it dropped and the previus owner couldnt tell either.
Any possible solutions?
Thank you in advance!
Sounds like a hardware issue, just for the heck of it I would open it up and check the ribbon cable to the digitizer/screen, it could be loose.

Checked it. Same problem. Tried to change brightness level, hard reset, rooting etc with no luck.
Its just so weird that in some situations the screen looks totally normal. only these few situations cause errors in the screen.
Hmmm, there are dialer codes that are used on phones that run a series of tests to check screen performance and output, don't know if this can be done on a tablet, but I would research it.
The only other time I heard of this was on a phone that recovered from falling in a toilet, the phone was dismantled and cleaned and assembled and it worked fine for over a year, the only glitch was an occasional color spasm on the screen similar to what you discribe.
Pp.
Thanks for the tip! Need to look for those codes when i get back home. I removed the logic board and cleaned it with denat. alcohol. No visible damage at least! trying to assembly it back later today. I decided to order a new LCD flex cable. Its the cheapest part to change.
No luck with the codes i found. after cleaning still same graphical problems. Now i can only wait the new flex cable and hope it will fix those errors.
Anyways thanks for replys and suggestions. :good:

Hello all, i have myself an 02 XDA Exec, but during the light of a soft reset
the screen is now working with fault
it looks like there is some sort of high contrast or the in could be bleading on the inside, but the touch feature works, will display pictures
Notice how the screen has different shades, but also patches in the corners of the screen, as ive mentioned the touch sensetivity works fine but the screen looks to be a bit pixelated and and in a different sort of contrast (i am currently reading up on the dis-assembly of it so if its something internal please say something about it)
and no i havnt banged it, smashed it, tried beating it up etc, i honestly dont know whats happened to it.

this is my today screen after a hard reset, basic windows mobile default, look at the different tones of colouring, the sort of slashes across the screen and the shades in the corner of the screen, and im not sure why, although i dont think it really can be ink bleading as when the phone is turned off the screen is as it should be, just off.
Now i will try out the camera on both sides, from the phone and from my camera
Camera's Side
Notice how the screen is in a sort of negative/contrasted style, not one im enjoying thats for sure, but coming from the phone the results are different
Exec Camera
notice how the camera still processes the image properly
which leads me to believe something is wrong with the screen
maybe some part of the frame is being pressed against it or something like that
i will be monitoring this thread closely and please help
With Many Thanks

Does it have this pink tint in reality too? (not only on the shots?)
If it does (and a hard reset doesn't help), then, one of the color transfer wires may be dead or have "only" developed a contact error (or, plainly, they have just been removed from their socket. This happened a lot with other models.)
That is, I'm pretty much sure it's a cheaply fixable problem. Try disassembling your casing and try to rearrange the wires.
pink/purple tint, but the screen apears in perfect shape
any guides on getting into the screen,
thanks very much.

there are several; see the "smashed my Universal screen" threads; some of them link in the official HTC disassembling guides
I have a treo 750. Its used and I don't know what the guy before me tried to do with it, but it looks like all he did was install the official WM5 to WM6 update. My problem now (and part of the reason he sold it) is that there seems to be some serious screen corruption. I'm inclined to think there may be a driver issue? I cant even see the bootscreen. All I can see are a couple of vertical and horizontal bars (mostly around the top) with a multicolor spectrum. The rest of the screen is blank. Hard-reset, soft-reset, neither works to fix it. Oddly, if I access the device through MyMobiler and regedit/change to font to something that it hasn't used before (ex. calibri, arial) it seems to bring it back to life... still no boot screen, but the os will work fine. If I put it in standby mode and then try and bring it back on, I'm back to the corrupt screen. At the moment I've turned off the power-idle feature and just let it go to backlight off while leaving the device on all the time, but I cant leave it like that forever. Any thoughts? Am I able to update the display driver or something?
PS. Display works on my PC through MyMobiler with no problem.
Thanks in advance.
having exact same problem
I am having the exact same problem. The only way to avoid the display corruption seems, like you said, to avoid putting the phone in standby mode... but then leaving it like that all day will drain the battery very fast, obviously.
I'm curious as to what the cause is. My phone is out of warranty already. Purchased summer 2007.
rjackets, have you done anything since your post?
Hey i Still have the same problem, did anyone find an answer yet?
Is this what you're seeing? http://commons.wikimedia.org/wiki/File:Bootloader.jpg
no, it's like all the 1st vertical pixels get extended to the right end and the lines keep flashing, i kind find my battery atm but it looks something like this texture, just with pixels:

A few weeks ago my Sensation screen turned to colorful pixel snow. After opening the sense lock ring and flipping the main screen for a few times it became ok. A week later it went back to the snowy screen permanently.
I went to recovery and re installed the Rom (revolution 6.80) and the problem was solved. A week later I got the snowy screen back, but now the snow appears the very first moment the device is powered on.
Due to the face I had airdroid on the device I managed to connect it to the computer and see the mobile screen on the computer and it looked as if everything is ok, I could see the sense and all the screens and operate all the applications by looking at the computer and touching the snowy screen.
I bought a new screen and connected it instead the original and I still got snow....so I know it's not a screen problem.
I do not have warranty on the device and local labs will charge half the price of the device for fixing it, so I prefer to find out what's the problem and but the parts myself and replace them.
Anyone has any experience with such a problem and fixing it?
Thanks a lot
Try using a blower, those that people use to blow off dust, blow off every spec of dust you can see on your device, clean the connectors of the screen too.
Then, try installing a rom which is not ARHD, and test it out. If all these doesnt work, it might be your GPU hardware is faulty.
I already cleaned all the connection and checked that everything is connected correctly but it didn't help.
Do you know where the gpu seats? maybe if I knew what it looks like i could check problems around it or replace it.
No one knows how to solve the snow problem? :crying:
That's it? the device is dead? I used it only for one year...
Can you take a photo of it and post it?
Then we know exactly what you're talking about

wow... I've never seen anything like that before. Hopefully someone else can help
maybe the connector of the lcd panel is disconnected a little bit.
I bought from Ebay defective Sensation, it has exactly the same problem.
Did you find what you HTC was wrong?

I'm also having the same snow problem on my HTC Amaze, for the above i assume there's no fix to this as i was about to purchase a new screen.
This phone is a complete lemon so perhaps it's a blessing
Seen that 2 days ago at a friends phone. No solution oder fix for that?
Good day my friends,
my OPO from the very first batch in early june 2014 works perfectly. My second One, bought in september 2015, worked also very well. Until yesterday when I noticed that the display is completely full of horizontal lines, all aligned with the same space and the same size.
I thought it could be a problem with CM13 and updated to the latest release, but the issue persisted. I updated to the latest firmware because it made a lot weird stuff in the past - nothing changed. I read about some DPI problems when setting up a custom DPI in settings, you should set the same DPI in your build-prop. Did it and nothing changed. Finally I switched back to the CM12.1 release candidate from november 2015 and .... the lines were gone. I was very happy, but confused because it seems I was the only one having this problem.
2 hours later I was randomly checking my phone... and the lines were back. They started to get visible alongside the upper edge, in the statusbar region. After some time the whole screen is full with lines. After some time with display off there is a big shift and you can see everything double (unfortunately no image of this). I got the doubt it may not be software related and made a screenshot and sent it to my other OPO. And yes, there weren't any lines. So I think it is indeed hardware related, but I was not able to find something similar. Many results for this big line at the bottom which occured in late 2014, but nothing similar to my problem.
Before asking for a RMA I'd like to post this here, maybe someone knows what is wrong. I really hope it is not hardware-related and I can refuse to use the (not well working) RMA and support of OnePlus.
And NO, my device didn't fall down or something else. To be honest it isn't really in use, I just use it an hour a day
I made some images for you to see my problem. Maybe you saw something similar on the internet. Thank you in advance.

After some further investigation I found an angry comment which states "horrible horizontal lines". Moreover it seems to be clearly a hardware defect when a LCD panel shows lines..
Go for RMA, faulty connector pins. Maybe from the factory, maybe from yours. Higher air moisture can produce chalk on the pins too, even while they plugged in
hello fiz:ik,
can you please tell me that how this issue was resolved? as i am having exactly same issue with my OP3T.
Afternoon all.
As per title. After installing Renovate 3.0 today, I noticed that I've "lost" about 5mm at the bottom - just a thin black bar under the display.
Thought the ROM was the culprit, but I've reflashed 5 or 6 Rims and it's the same.
I've tried all display resolutions, immersive mode, different themes, clean installs, soft reboots, too many restarts, toggled everything I can think of- the same. All screens, all apps.
Driving me absoeffinglutely nuts. Any help appreciated!
Have you tried flashing back to the factory firmware?
Take a screenshot, does the black bar appear in the screenshot? If not, the display panel is broken, if yes, it's a software glitch

No, doesn't show in screenie, didn't expect it to. Find it hard to believe it's physical damage - never dropped it, Otterbox Strada wallet, but somehow the display is FUBAR.
Seen one similar problem after googling, on the S8, no obvious cause or solution.
Going to wipe everything including system and all storage, flash a stock in Odin and cross my fingers.

Very odd, if it appeared right after you installed the ROM, a software problem is possible. But I still wonder how it's possible for a part of the screen to render on a screenshot, but not on the actual screen.
