Hi,
I have a HTC Desire Z, one day I pulled it out of my pocket and the screen was black with white lines. After reading that it was most likely a faulty LCD, I purchased a replacement from ebay. I installed it following the instructions in this video

After installing it the screen remains black. I can hear the start up music playing but the screen is black, no white lines like before. I even tried reinstalling the original lcd and the same thing, no white lines. Also after starting the phone up the front seems very warm.
Could my replacement lcd also be faulty or does the problem lie elsewhere?
Thanks in Advance
Ok, I took it apart again just to double check the lcd ribbon. It was on good, however I took it off and put it on again and now the screen works!
However the brightness is set to the lowest and even if I change it to the high setting it remains the same. Also the automatic change doesn't work either. Any Ideas?

My screen turns to random color from pinkish to red and purple to monochrome(black and white). It started when I highlighted a text into my message box and then suddenly it turns to pinkish red display. And then everyday the color changes randomly.Here is the display.
Hi,
does it also happen while boot, or when you in recovery, etc... ?
If yes, it is probably a hardware issue. If you are under warranty, send it there.
If no, you can try to disassemble and check the connectors if all is firmly in place.
I also read once about a broken display. Spares can be found on ebay, etc.
Yes it happened also while booting. I am not sure what to do with this problem if there's just wrong with the amoled adapters or i need to buy amoled display.
Hi,
well if you think you can manage it, you can disassemble it. How to's can be found on youtube.
Check if anything is loose. But be careful not to break any thin wire.
Hello,
I disassemble my Desire to replace the cover of it. The AMOLED display and the touch screen worked with no problems. I disassemble every part but had some problems by removing the touch screen so it was broken in one corner. I ignored it, replaced the cover, put all back together and attached connectors for display, keyboard and touchscreen. After that I start the phone but now I get only a black screen. I see nothing on the display but my phone starts because I feel the vibration and the lights of the buttons are glowing.
So, is there any option to fix that or is it now completly broken? I'm really sad because it worked with no problems a few hours ago and because of this cover replacement I have no video screen now.
On Ebay I can get a new AMOLED Display for 40$ (30-40€). Should I try this or is maybe the main PCB broken? The broken glass of the touch screen can not cause this problem, wouldn't it?
Greets,

Hi guys, I recently replaced the glass on my note 2 and the repair was successful. Everything on the phone is fully functional.
However, I notice that the phone sometimes switches to a strange discolored mode and then back to normal.
When the display is discolored, it looks like what is happening in this video:

So does anyone know what the issue is? Have I damaged the ribbon cable somehow?
The LCD and digitizer seem to be unscathed. When the screen is not in "discoloration mode" the colors are crisp and clear.
Something really strange I've noticed is that sometimes the screen only discolors when I pull down the status bar. It will only be discolored for the status menu. The rest of the screen will remain fine. This does not happen all the time. Sometimes the entire screen has no discoloration at all.
I'm not sure what I've done but, any feedback is appreciated, thanks!
Hi,
Unfortunately for me i dropped my phone and cracked my tempered glass in several places. gladly the screen underneath was perfectly fine after drop however, it has developed a fault as the screen won't turn on at all. I tried turning it off and restarting and although i can hear the boot up logo sound i see no picture at all. i can receive calls but cannot answer due to screen not displaying.
The screen had four main pressure cracks.... one is top left, one on the ear speaker, one bottom middle and one bottom left of phone. hopefully you can see it in picture.
Can you give advice on what to try or do to resolve this? will i need a new screen or disassemble to see what the issue is?
I've only had the phone for 2/3 months at most
Thanks in advance
looks like i will answer my own question....
i bought a replacement lcd & digitiser, one complete unit and swapped the necessary components over to new screen. all is working and good. not sure if the screen is repairable but there are other parts inside this screen worth selling on. it still has a non cracked immaculate screen along with the charging port and other stuff inside old screen.
at a cost of £70, i consider this an expensive fix
Thanks for the input kakawak
cheers
Hello, today I replaced a broken lcd in my Redmi 7, my problem is that before replacement, I could see something on the broken screen (red, green and blue lines), and now after I replaced it the new screen shows nothing, even the backlight doesn't work. The phone boots normally, and even the digitizer works, but the screen is black. Oh, and also now the old screen doesn't show anything. What could be the matter of it? Please, any help would be appreciated.
