[Q] replacement LCD not turning on.

Hi, I have a droid 2 global, it belongs to my friend. She dropped it and this screwed up her touch functions. The screen was turning on but she was not able to get any feedback when she touched anything on the screen. I told her i'd try and fix it for her, first thing i did was ordered a new digitizer thinking this was the problem, unfortunately it was not. Even with the new digitizer i couldnt slide to unlock or feel any haptic feedback. I reopened the phone and looked for another possibility to the problem, i found a little tear in the flex cable connected to the digitizer, lcd and keyboard, somehow in the process of removing everything i think i may have ripped it. I ordered a new one of those, put it all back to together and this time the screen didnt turn on, however when i touched, it responded by vibrating. So that solved the previous problem. But now i have a new problem, the screen just stays pitch black. I was reading around and some forums said i may have short circuited the lcd through ESD. so i ordered another lcd, i put a new one in thinking this would fix everything, but still the screen stays black. Im resending the lcd back and gonna get a replacement, hopefully the one i got was just faulty. Does anyone know if it could be something else thats causing the black screen?

[Q] TF700 Dropped Display Issues

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 ??

Display problem

So my phone suddenly started flickering out of the blue. And had lines going down vertically. I restarted the phone and then the display was fine but the touch screen wouldn't work. Upon another restart it was just a blank screen with white vertical lines.
Figuring something must be wrong with the screen I ordered a new one, and upon install the new screen has the same problem. Blank screen vertical white lines.
Not sure if another component is faulty.
What do you guys recommend?

Did you drop the device? Sounds like component damage somewhere

Not sure what happened, just started happening randomly. I know its a hardware problem not a software problem. What component could it be?

So the mic piece has a long strip that connects to the motherboard and when I press down on it or wiggle it, the screen flashes so im assuming that component is malfunctioning, and I found a replacement piece on amazon for $17 bucks with prime shipping so hopefully Wednesday the replacement piece will fix my issue.

Problem with Display-exchange

Hello,
First of all i dont know if this is the right forum for my question. If not so please notice me.
After my Z5 dropped on the floor i got an broken Display. I bought a new Display and changed it, but i think i broke the LCD-Flexcable after i pulled carefully on it to get it inside the case. The effect is after phone turn on i get only the backlight but the screen remains black. So for a test i switched my old broken display in it but the effect is the same, only backlight and black screen. After a few seconds the phone led blinks 3 times red and the phone restarts. What the heck is now? Anybody get the same case? I handled the mainboard with care, dont remember to damaged the connector in anyway. Does the Flexcable needs to be protected with a tape so it couldnt be grounded on someway?
Sorry for my bad english. Thanks for any help!

After a second and a third display swap the error is still the same. It seems somehow i damaged the motherboard. I swapped the phone against a new one.

Please help, same problem ...

Charged the phone while I was doing some work ,I unplugged it at 90%,at the moment I didn't realized that the screen is yellow.After a few days I saw that the screen was a bit odd,if the screen shows a black photo,were the yellow spots are white.

Did it fall on the floor, took bad bumps, stayed on a heat font for a long period..? It's too much bizzarre to face this as a result of a software issue/error. You could try to send it to service center saying that you found it like that from one day to another, if it isn't a result of an accidental impact caused by you they should fix that by replacing the screen.
