white screen after fixed touch screen :(

Hi, i'v got a problem. I tried change my digitizer and, when im done, now lcd doesn't work, because it is still white...:/ What can i do now? any solutions?
Thanks a lot

Check your connections. Pull apart and re-seat everything to ensure everything is hooked up good.

everything is fine :/ still white screen

Perhaps you zapped or damaged the LCD when you were working on it...
You could try replacing the LCD too -- but at this point I think I would send it to the professionals
HTC repair or someone like PPCTechs

Don't know if the screen set up is still the same. But when I replaced the screen on my Universal the wiring for the touchscreen was stuck down onto the lcd wiring, as they both shared common earths. Maybe worth a check before spending more cash?

i have the same problem, the screen was working fine before i replaced the new digitilizer and now its just white but i can hear the tablet playing so it must be the screen.i checked all the wiring 4 times now! any idear???
:crying:

Slide the phone open and apply some pressure near where the angle of the opening is (back of the LCD below the SIM, where there is a bar). I had the same issue and this fixed it.

Droped my HTC and the screen is black!!

if you call it from another phone what it does it vibrate only!!
what do you think the problem is?
any solution?
thank you and sorry for opening such thread for this proble

screen black
Probably the internal Flex-cable is released. You must open the Diamond, removing the screws and see if the FLEX CABLE below SIM-CARD not this out.
Look for a tutorial to learn how to disassemble it.

Help!!! Problem with HTC HD7 screen

Hi, I recently dropped my phone and now the screen is blank. When i turn on the phone the whole screen is blank, the phone vibrates when it powers on but nothing is visible. Even when i get calls i cant attend them. There are no scratches or cracks on the screen after the fall. This is the first time i have experienced this and any help is appreciated. Thank you

I think the LCD is connected to the phone's main board by a connector that snaps into place. If you dropped the phone, I think it's a possibility that this connector could have popped out. It would only take a few minutes to open it and check for this. http://www.youtube.com/watch?v=0A4zbBKkcKU Skip to 2 minutes and 50 seconds into the video and you will see this connector.
Unfortunately it's possible that when you dropped it, the LCD screen was damaged even though you can't visibly tell just by looking at it.

thank you very much will try it

Backlight problem after replacement

Hello everyone,
I have got one problem... I broke digitizer of my HTC Desire 500. So I order new one and to be sure, also LCD screen. I replaced, and...
After turning on, everything works fine. Digitizer works properly, screen shows normal picture. But after few minutes - restarts (I don't remember well) backlight of my screen goes down and now it have no backlight at all. I rebooted phone many times, I remounted screen and digitizer to be sure that connections are fine - but no results. I restored factory settings of phone with no effect too. :/
Please help, what happend? What could be the source of problem? I don't want to order new sceen if it could beak too ;/ I read other threats about coil problem in other HTC, but I cannot find any coil in my Desire's motherboard (maybe it is hidden under plate that covers CPU and other parts). I performed tests of light sensor and it works fine. Buttons lights fine too. The problem refers only to LCD screen, and backlight doesn't respond during test.
Anyone help?

same situation
Hello kowal_luki,
I'm just in the same bad situation.
After a bad fall of the phone the screen broke so I ordered a new one for replacing it.
Opening the phone I noticed that also the LCD (and not only the external screen) was broke so had to order also the LCD.
As precaution tried to power-on my device without a complete assembly and everything seemed to be fine, so I decided to glue the LCD to the outer screen (the touch screen) with a LOCA TP-2500 glue.
Then I re-assembled it up: at first the image was a little bit disturbed but the back-light was working; after few second the back-light turned off. I checked the cable, after that the image went perfect but the back-light still dead.
Did you find a solution for this -still not explanable- problem?

[HELP] Black screen on new phone screen

Hi, my screen broke recently and i can't use the tactil touch. I can see the image but can't use. So i decided to buy a LCD + Tactil Touch + Frame. I didn't mount yet the screen. I only disconneted the screen flex and connected the flex of the new screen. But the problem is that is black. The screen seems to turn on but i don't see anything, is all black.
EDIT: I don't know where to ask. I flashed to the stock ROM, 4.2.2 and still black. I updated to the last version Sony has for my phone, 5.1.1 and still is black. I don't know what more to do. Is all working good, even the sounds when i touch the screen. But i can't see anything the screen is working but there's no image. My phone is Xperia Z.

Anyone?

Please help!

Broken screen? Is the old one still working? If yes: return the new and broken display and get a replacement!
The touch("screen") and feedback (vibrate and sound) will work without the lcd! It is a different layer on the screen and is seperatly connected to the mainboard of the cellphone. Also your screen could be working and your backlight not! Turn on the phone and point a bright flashlight on the screen, maybe you will see something, but even then, get a replacement.
