[Q] Motorola defy LCD screen not working after drop - Android Q&A, Help & Troubleshooting

I dropped my defy face down while talking on the phone. The still works except for the LCD display.
The phone rings when I get calls, I can answer and talk on the phone. But the LCD screen is blank. I can see the backlight is on. But nothing on the LCD.
I am not sure what is damaged. Is the LCD screen damaged or did some electronics get damaged?
I opened up the phone and tried reconnecting the screen. But no use.
I also froze the phone overnight. But again no use.

[Q] Blank screen after replacement?

Hi,
I got a HTC Legend with a broken screen and digitizer.
I replaced the screen and digitizer without any problems.
I turned on the phone, and the screen went on and showed the android boot screen.
30 seconds later the screen went blank, and now it doesn't work.
It's like the screen displays white/black pixels every second ribbon
The phone still turns on and plays the "startup sound".
I have cheched the ribbon cables, but they all seem fine.
Is the screen broken or is it something else?
Any suggestions to what the problem is?
Thank you for your time
My Legend screen was cracked a few days ago after the phone fell, I was looking to get a new screen as well. Where did you get your replacement screen from? It looks like you got a faulty screen based on what you've said.

[Q] HD2 no backlight but touch screen works.

Hi I recently dropped my T-Mobile HD2 in a puddle of water very briefly i took the cover off and battery right after it happened and wiped everything down. The phone worked flawlessly for about 6 hours then I finally got a black screen. The phone will turn on boot into android(2.3 NAND) and the touch screen works plus im able to recieve calls and messages BUT the only way to tell is to use a bright flashlight to see the screen as I have NO BACKLIGHT. Help me please?
You have probably dead light emission layer. By all means, LCD is to be replaced.
You shouldn't turn phone on immediately after accident. Removing battery immediately, complete disassemble of every possible piece and letting it rest for 2-3 days in warm dry place is a proper way to do this. Next time of course.
So just replace the LCD? Should I order a digitizer with it? Thanks in advance.

LCD Backlight is on but there's no video output

Hello!
My phone fell from a high place some weeks ago and the screen shattered. Touch was unresponsive, clicking everywehere, but LCD was fine, i could see everything on screen normally.
Ordered a new screen. Changed it, but when I turned it on, only backlight of the LCD was visible, but it was displaying nothing. I thought it was a defective screen (either way, it was, lots of stuck pixels), sent it back and bought another from the same seller. When I changed it and turned it on, again, no video output, lcd would light on but woundn't display nothing on screen. Googled a bit, found out it could be a defective fuse on the motherboard, and that soldering it again would solve. I know nothing about this kind of stuff, so I picked up a tweezers and apllied a little force on every fuse, because I thougth that way I could try to solve it. Well, it worked, kinda. I put the screen above that blue plastic glue only for testing, and it worked, I felt reliefed for seeing sony boot logo again. Figuring out it had worked, i took out the screen, took out the blue plastic, and glued the screen back on. For my surprise, it had the same problem as before, and it doesn't matter what I do now, it wont work anymore, only displays a black backlight with no video.
Could anyone help me out with this? Give me a hint of why it worked once but not anymore. Could it be there's really a defective fuse, or it was just a coincidence that it worked after it had force apllied? Also, the Screen flex is kinda loose, it keeps coming off all the time, and it's really hard to plug it to the LCD sometimes, is it supposed to be like that, or could it be the culprit? Also, touch is working normally, i can't see nothing on screen but i can click and feel it vibrating.
It's kind of a big text, but that's the way I could explain it. Sorry for the bad english, it's not my native language.
And thanks in advance if anyone can help!

Touchscreen ghost touches(screen flickering)

Hey guys, recently I had my Z2 sent to a service shop because it wasn't turning on or charging. The guy at the shop said that it was the battery fault and he changed it, but he also told me that the screen was not working( flickering, ghost touches, unable to work on it). So he put my old battery on and when I went home the phone actually turned on and booted up, but still I had the screen problem. So whenever I touch the screen it doesn't respond and it touches by itself. Tried putting it on rice for 20 hours, dried with a hairdryer and assembled dissamssebled the screen jacks, still the problems wasn't fix. Do I really need to change the whole LCD or is this a problem that can be fixed?

Yes, you have to change the screen, or more precisely, the digitializer.
But since the LCD and the digitialier come in one-piece, you have to change it as a whole, but at a much lower price, as your screen can be sold again and recycle the good LCD panel.

So replacing the LCD would fix the problem right? That's great then because I found an LCD with a very low price (20$), completely new on ebay and I sucessfuly dissassembled the old LCD out of the phone. I'm gonna buy it as soon as possible. Thanks man.

Screen start flickering when in charge

Hi guys,
when my phone is in charge at 100%, after some minutes it start to flickering when there is at least an orizontal black line and a white part, for example if there are 2 notifications there is an orizontal black line that separates the two notifications, right? The white part of the notification start to flicker. I tried to hard reset and nothing changed, and also got my display replaced and nothing changed (huawei customer service said they will replace the mb, but idk if this will solve my issue).
Anyone have this issue or it's really a faulty mb ? I tried searching online but it seems that no one have this problem.
I'll upload later a video that will show my issue...
Have you dropped the phone? Even from a small height it could cause problems.
My old p10 plus fell out of trouser pocket and hit the inside of door panel but was enough to cause screen flicker.
I had a hairline crack in digitiser/screen.
It only showed when screen brightness was on low or if phone was cold.
Got the screen replaced and was ok after.

I dropped my phone only 1 or 2 times and always with protection, but even after the display replacement the problem didn't solve. It only flicker when it's in charge and already at 100% and when I unplug the charger, it stop. I noticed this problem only after I got my display replaced for the gluegate... but even after a second replacement nothing changed. I hope after the mb replace, my phone stops to flicker.
I have the same flickering problem with my Mate 20 Pro and have never dropped my beloved smartphone. For as of right now, the current (.232) update may have resolved the issue but it's only been a day since the patch. I will see how it goes.
edit: nope, even after the (9.0.0.232) software update, the flickering issue still remains as the original poster has described.
