Okay so yesterday I came back upstairs from doing some stuff downstairs. i pulled my phone out of my pocket and bam, there's a white screen with colored lines all over my screen vertically. Almost like if you would take the screen and stretch it as much as you could. You can t see anything. So i decide to see if the touchscreen still works and well, it does! I can even receive phone calls.
The phone is rooted, and has a cracked but functional digitizer, no water damage nothing. I have tried turning it off and on, and well in order to take the battery out i would need to open it, which i only want to do if i need to replace the LCD.
So my question is, Is it the LCD that needs to be replaced, or could it be the hardware. Any fixes guys?

I think that the LCD Panel is damaged, it is not the hardware since your touch screen is working and colours can be visible on the screen. So just change the LCD Panel:thumbup:

I recently got a touch pro of a friend with a damaged screen that didn't turn on but the touch screen was responsive. Apparently he sat on it and the screen broke.
I then acquired it and replaced the LCD screen and i turned it on but all it shows is a blank black screen with the backlight on. I was tapping while it booted up and it was making that beep noise so i know the touch screen works. What do i do now.

if the lcd is damaged and you only replaced the digitizer then that wont solve the problem, the digitizer just sits ontop of the lcd and recognizes your touches, hence why it mite know that your touching the screen but the screen is still blank

I replaced the LCD along with the digitalizer. Tats what i meant.
Sounds like either the new screen is inop on fit (fraid you need another to test, then send the first back as faulty), or the fault is not the LCD itself.
Possibily its the wrong screen, or its not installed correctly, or you damaged either the screen or the controller when installing.
I'm afraid you dont have many options - take it apart & rebuild to ensure correct parts & fitment, spend £££ on alternative parts to see whats broken (or serious £££ on test equipment!), send it off for repair or give up!
I'd go for option 1 first
If your friend sat on it hard enough to break the screen, i'd be looking for any damage / cracking to the boards / ribon cable mounts and be looking very carefully at the mountings of any IC chips. Incedently, when (s)he sat on it, did the screen work at all? and was it 100% working before they did?
Okay thanks for the replies. I just bought a flex cable where the slider thing is because the old one looked a bit old and flexed out and on inspection of the old screen i found a tiny rip on the screen's flex cable too. I wait for my cable and see if it works and if it doesn't then i'll sent the screen back as faulty and get a new one and if that doesn't work then I'll give up and sell it again
hi
sorry to wake up an old thread.
so what's your solution/conclusion?
is it the flex, or the LCD that broke?
i have the same problem right now.
thanks

I dropped my TF700 with the dock and it fell on its back(tablet). It closed shut and when i tried to restart it i do not see any display
later the display comes up but in jagged lines half black and half display, the touch doesn't seem to respond , i can see that it boots
and i can access it on my computer all the files and entire system but i cannot do anything with touchscreen and lcd. after repeated touching
it has the touch sound that comes not very often.
I opened the screen and i see no physical damage to the screen. Is there an inverter board of LCD that might have gone bad due to that
or has any one faced this problem , so that even if i have to order a replacment part i know which one to order first i thought of
ordering the LCD + Touchpanel but it looks like i am doubting that the LCD has gone bad.
Can anyone please help if they have faced this issue ??

Hi
I am trying to fix my Nexus 5. Couple months ago I dropped a mug on the phone. The result: cracked screen. I ordered a new screen with the whole front housing so only thing I had to do was remove cracked screen with frame and replace it with new one. When I did it I turn on the phone but I saw only a short blink of the screen. After lots of attempts of I came to conclusion that I probably damaged the new screen or it was already damaged. So the screen is black. When I plug the phone to PC everything works perfectly. I can browse the memory etc.
I would like to ask you whether my conclusion is correct and the only issue is the screen which has been damaged by me or the seller.
One more thing is that when I charge the phone or it is attached to the PC beside the black screen I can not also see any light from notification led.

If the old screen can still display an image, move the parts back to the old screen to check for issues.
HI. Thx for reply. I don't remember whether cracked screen was functional in terms of displaying image. I will try to attache the old screen and will let you know.

Hi,
I have a clients phone, They dropped it into water. Phone LCD worked fine, touch screen did not function correctly, and the bottom soft buttons were activating. making the phone unusable.
I orded a new screen, and decided to test it, before installing it. After removing the mid frame, I plugged in the LCD to find a strange grey snow pattern. I disconnected the battery, reseated and checked the LCD cable. I got the same pattern,
I was positive the new LCD is faulty, but not 100% sure now.
I reconnected the old screen and have a similar but not identical pattern. I can understand breaking the old LCD while taking it apart, or getting a faulty new LCD, just unlikely for both to happen.
Are there any other connections I should check. What do you guys think?
