[Q] No dislplay after replacing screen - Windows Phone 8x by HTC

Hi everybody, I have problem with this phone. I tried 3 difference screens (replacements without chassis) and everytime was the same syndrome. Can not turn on the screen and after touching digitizer, can feel vibration so touch screen works. Its not possible I have 3 broken screens.Under youtube disassembly tutorials I also have seen many feedback form people who have the same problem. Anybody know what can be wrong ?
Thanks a lot for all comments
Cheers!

Broken Fuze, Touch Screen Doesn't Work

Recently my Fuze's touch screen completely stopped working, and a little blue drop appeared on it. Looks like others have had this problem before but I can't find any solutions on here or any success with fixing it (if anyone has any ideas, let me know!).
Anyway, what's the going rate on a Fuze in this condition? Do people still buy these for parts?

[q] help me !!!!

I have bought it month ago, and it looks like I found the problem on the sensitivity of the touch screen. I feel the sensitivity of the touch screen is less sensitive, so I have to touch the screen a little harder to be able to run it. I've tried removing the screen guard, resetting the phone, and update it but to no avail. I think to try to find the calibration software but it is hard to find. Anyone experienced it too? please help me resolve this problem .. Thanks in advanced
Thats a normal thing. I have experienced it too. But after time you won't notice that.

Black screen (but backlight ok) after screen replacement

Hello
I just replaced a broken screen on my moto g (broken glass, but display+touch was OK).
Once reassembled, the screen remains black, but the backlight is working and the phone is booting (I can even see its content via usb).
I also tested with old broken screen but it's the same.
I even found a thir lcd to test, and same result.
Does anybody already experienced same thing (I think yes, because I saw such comments in disassembling videos).
Does it mean I damaged something on the mainboard ??? what could it be ?
Thank you for your help
Hi, did you ever fixed this problem? I'm experiencing exactly the same.

Click to expand...
Click to collapse
Yes, same problem here. Anyone have any ideas ?
i had the same problem with my moto g and the problem was the screen brightness was turned right down, so best thing to do is try goto top of screen with your finger and try scroll down and swipe across where the brightness bar is, (if you get what i mean lol)

LCD screen freaking out

Hello everyone, I must first thank you all in advance for your time to consider the issue I'm encountering.
Background:
Android 4.4.2
Unlocked Bootloader
Rooted
Able to boot into recovery
Issue:
Out of the blue it seemed I started suffering from the black screen issue, so I power cycled the phone and still had no display.
I took the phone apart to see if it was a small issue of the LCD ribbon cable getting knocked and managed to get to this stage.(See video link below, please excuse the coughing the household has got man flu )
Video Link
So I managed to get it to boot up and the screen is very glitchy, the digitizer is fine as shown in the video.
The Punchline
If I've already determined the LCD issue is at fault then why am I asking your kind folk for help you may ask?
I'm asking because I want to be sure it is merely just a LCD fault and not something deeper. I don't want to order a replacement screen only for the issue to persist.
Update:
Navigates settings fine, tried disabling h/w overlay to force GPU rendering but that made no difference. What also happens if I were to swipe left and right again on the app drawer the screen would eventually just fade/burn out to black and not turn on again unless I rebooted.
This leads me to suspect this maybe deeper than a LCD issue and more a hardware issue in regards to the CPU/GPU.
Thank you all for your time.
Kind Regards,
Ryan
