Hello. After I had to change the motherboard and the rigid flex board (and everything works fine) my screen started developing strange colour problems. It can't represent dark gray and dark blue correctly. I have uploaded a picture of my homescreen and a picture of a gamma test.
Here is the gamma test image on my phone, and here is the original. That is my homescreen and that is the image on it.
I have ruled out software issues because I reversed back to WinMo6.5, then to Android ICS NAND and then to Adnroid JellyBean on 4ext (with the accompanying radio, magldr etc.). I dissassembled the phone once more and checked the cable connection form the screen to the motherboard. Is it 100% certain that the screen is irreversably damaged? I think I know the bitter answer, but U just want to make sure

i fear it's damaged... i had a screen issue on my hd2, tried with android and with WM 6.5 but i had to send the device to HTC to get the issue fixed... now, after screen substitution everything works fine
it would be useful if you can provide a screenshot taken by the devices, so we'll understand how Leo thinks he represents colours

Hi helpers! In the camera viewfinder image and in the resulting photos/videos I get a thin blue vertical (or other color) line where the lower edge of an app title bar would end (on the right hand side of the screen) This didn't happen when I had the standard O2 xda neo rom (which probably came with a different camera app and driver version)
Am using: HTC camera ver 3.02 build 23018
Do you also get this thin vertical line? Its incredibly annoying...
what ROM do you use, search I posted drivers of the camera here
do you overclock your CPU?
Have got the permanent thin blue (or green line) in the viewing area and in the result picture since moving from an original o2 germany rom.
Specifically I get it with:
- NVID 2.2 WM50 (the rom used to switch to, before upgrading to WM60 - this ROM upgrades the SPL and IPL!!)
- Smart1v2 WM60
- TrueNeytral WM60 1.4 (newest version)
And no I'm not overclocking. However, even at 270Mhz the camera takes good fotos and videos with no strange colors (NVID and SMART1 cameras were unusable overclocked).
Am currently running the TrueNeytral WM60.
Is no one else getting this? Very strange. I would be grateful for any help.
Try dissamblying your phone and check the camera flex for dust or something. Plainly unplug and plug the camera once again.
Can you unplug the camera??? that would be fantastic!!! I am actually not allowed to take the phone to work as it has a camera in it.
How do I do that? I've opened up my phone and couldn't see where to unplug... do I have to pull out the whole daughter-board?
you have to open the whole phone to see the board. check out on google or here for dissamblying toutorial. Its pretty much the same as magician or charmer.
thanks, I'll give it a try (again).
dust or unflixable will not make a then vertical line I think
it may be driver (((I had one with ATI RADEON, gone when have new driver))) try the 2.20 official Qtek
or hardware, the device has a big shock and it can't be fix
I get blue dots in low light places when have more light it gone
I hope it is dust or if you plug it and unplug it it will be slove, but be carefule you will lose warranty if you have one check the warranty services
Due To Overclocking Only
1. disable overclocking causes remove thin blue/green line from camera
i have this strange behaviour taped it on camera, have a look:
http://www.vonkuttenberg.com/temp/pub/mda_compact_poskakovani.avi
have you ever seen that? what do you think? i have this phone without guarantee, flashed to czech ROM 1.13 about three weeks it was fully ok and now after few weeks it makes this things half a time i am using the phone + fading out to white colors or color stripes which are not seen on video... works ok, calling ok, but just the display is strange, no falls, nothing why to start... hardreset did not helped.
PS: gray case is just changed from charmer, but it is magician.
Check the flex cable connection from LCD. May be it's not connected properly. Unplug it then clean with small piece of cotton and little alcohol, then connect it again, but be very cearful, becuse it's very sensitive. If the problem still persist try with another working LCD.
Post results pls!
Sorry for my bad english.
Motto:
If you ever walk down the stairs wearing slippers and talking on the phone make sure your free hand is next to the stair handle...
The phone went down through the staircase gap - from the 1st floor directly to the ground.
Aside from the aesthetics and the potential hazard of small pieces of glass going down my ear, everything seemed to work and I could use the phone with full functionality.
I just recieved the phone from the local HTC service after 2 weeks.
I thought only the digitizer will be replaced but instead they replaced the whole touchscreen assembly with 200 Euros:
- screen (digitizer + LCD) ~142 Euro
- middle chassis ~18 Euro
- keypad ~23 Euro
- service fee ~17 Euro
I was told they couldn't replace only the screen because the whole module comes pre-assembled by HTC.
I still don't believe that but I decided not to reject the repair (+ find another service + wait a few more weeks + risk the same or other issues) for the extra 40 Euros...
After thorough testing all day long I find everything is in place but I also notice some differences compared to the original:
-the green LED is not working;
-the screen is noticeably darker on auto-brightness level
I don't think it's a software issue because I reflashed the stock ROM and also the light sensor works, so I guess:
- either the hardware parts made by different OEM are not the same
- or, the sensor and speaker modules weren't remounted properly
Anyway, for now I'm happy to have the phone back and thought it would be nice to share my experience with you...
Edit:
not only the screen is definetely darker in any OS (WM6.5, Android, WP7) but the whites have a subtle green tint
i'm afraid i'll have to send it back but i'll go with another HD2 this time, to prove I'm right...

yea deff send it back. they use returns for parts, so you probably got one that some minor tech took a quick look at and thought 'yea that works' and put it in the spares pile.
thanks for the advice samsamuel
this cannot be "htc authorized" service quality, i am very disappointed...
im 100% its not original lcd... i change lcds ( not hd2 ) every day and how you described definitely thats not right lcd... so like samsamuel said send it back.
things start to get wierder...
the screen seems to get better by itself
to be sure my eyes don't fool me, i compared the min-max backlight levels against both another hd2 (in android) and a desire.
i don't understand how but it looks fine now, even the colors. i use a custom color for the live tiles in wp7 - yesterday it didn't look ok, now it does...
still, the green notif led doesn't work but i don't know if it has anything to do with the screen. as i saw in this video, it looks like the notif leds are integrated in the receiver:
http://pocketnow.com/hardware-1/official-htc-hd2-disassembly-assembly-training-videos-leaked
the most annoying issue however is something i discovered only yesterday. the g-sensor doesn't work at all in any android buid. what's strange is that it works perfectly in both wm6.5 and wp7...
as i found out, i'm not the only one having this issue:
http://forum.xda-developers.com/showthread.php?t=1069578
it's like i'm playing in a "twilight zone" episode...
UPDATE:
the phone came back from the 2nd trip to the repair shop.
- the issue with auto-rotation in android was related somehow to the compass (magnetic field sensor) which apparently didn't work in any os - solved by motherboard replacement (under warranty)
- about the screen brightness - it's not a bug, it's a feature - as i was told, all the screens in the new batch from htc have a slight yellowish tint (visible on white) and i have to live with it
- the notification led works now
Today my hd2 has shown some strange color issues: Grey / Transparent black causes a grin/yellow tint. I did the usual troubleshooting (soft and hard reset) but it did not help. I also read some old threads about it saying that I should flex the screen to make it go away (http://forum.xda-developers.com/sho...m.xda-developers.com/showthread.php?t=1003265). I tried that without luck though I'm not sure if I "flexed" the screen enough but I'm afraid of breaking it.
Anyone an idea what caused this problem? I did drop the phone a few times over the years, however, today, when it all started, not. Secondly, I can't really think of a broken screen as it seems that only a specific grey is tinted yellow/green (the grey whatsapp uses for their contact without photos and the grey used for the keyboard when you eneter your pin.
Any help is really appriciated... Don't want to loose the king :crying: as this color issue makes really unconfortable.

EDIT: I'm on a european hd2 with the latest Pdaimatejam WP7 rom (v8.2) and I even tried to reflash the rom... Seems a hardware fault:crying:
Today morning the issue faded away without doing anything at all . Might be that the screen got somehow pressure causing some disorder of the fluid crystals and with time, they reordered themselves...
I've got a D801, and ever since updating to 30c I've been getting white lines on the screen. Does anyone know how to fix it? I tried testing the antenna for interference with the display, but couldn't get that fix to work.
Here are some pictures of what the screen looks like.
Install stock KDZ with LG Flashtool 2014. If it is software problem, it should be fixed. If it is a hardware problem, check screen connection on mainboard.

Tried it. The problem still exists.

I'm leaning towards that as well, but the connections all seem to be seated properly, unseating and re-seating them didn't help, the orange ribbon cable has its kapton on it (and providing extra insulation with some electrical tape didn't help), unplugging the antennas didn't help, trying to keep the ribbon cable as flat as possible didn't help, etc..
Thank you for the suggestions though. I really appreciate it.
Here's a quick bit that I added to my post on reddit about this:
edit: The markings on the display ribbon cable say LG and none of the kernel fixes seemed to work, so it's probably not the kernel issue. I'm guessing that it's either something more serious with the mainboard/orange ribbon cable than I can fix (like the link above talks about, with some people mentioning potential shorts), or possibly a more severe version of something like this (a lot of the symptoms seem to be the same).
I should note that there are both horizontal and vertical lines (lining up with whatever is on the screen), primarily white but there are other colours as well if only other colours are on the screen, it gets worse the longer you leave the screen on, it has a bit of a white mist looking thing to it as well, it is substantially worse on any screen with white on the screen than what it looks like when it is an all-black screen (although there are still issues then), **it is present at all times (including in the bootloader, in the recovery, and on the LG screen)** and it has an after-image of whatever was on the screen recently (even if you turn it off and on again, it will still hold the after-image).
I'll update if I find a fix.
