No Display after dropping phone - LG G7 ThinQ Questions & Answers

Hi,
Unfortunately for me i dropped my phone and cracked my tempered glass in several places. gladly the screen underneath was perfectly fine after drop however, it has developed a fault as the screen won't turn on at all. I tried turning it off and restarting and although i can hear the boot up logo sound i see no picture at all. i can receive calls but cannot answer due to screen not displaying.
The screen had four main pressure cracks.... one is top left, one on the ear speaker, one bottom middle and one bottom left of phone. hopefully you can see it in picture.
Can you give advice on what to try or do to resolve this? will i need a new screen or disassemble to see what the issue is?
I've only had the phone for 2/3 months at most
Thanks in advance

looks like i will answer my own question....
i bought a replacement lcd & digitiser, one complete unit and swapped the necessary components over to new screen. all is working and good. not sure if the screen is repairable but there are other parts inside this screen worth selling on. it still has a non cracked immaculate screen along with the charging port and other stuff inside old screen.
at a cost of £70, i consider this an expensive fix
Thanks for the input kakawak
cheers

Touch screen problem after switching LCD

Hi,
a while ago, I cracked my Uni's LCD. So I ordered a new one including the digitizer, opened my Uni and swithched the displays. Now at times, the touch screen wouldn't work at all - unless I tap the upper left corner (the start button; in portrait mode) or the lower left corner (the left button or slightly above it; in landscape). After that, tapping everywhere works normally. Does anyone have an idea what this could be caused by or how to solve it?
Thanks in advance!
I'd make sure your contacts are very clean. If you think maybe they're not, then take out and clean contacts with dry cloth or contact cleaner and re-insert.
Also, make sure there's no debris around screen. That nothing is pressing on digitiser anywhere else that gives false postive for it.

Generally, all touch problems are associated with a digitizer. Without actually seeing your device I assume your digitizer is faulty and the problem may be either improper adhesion or the soldering joint improperly formed. Adhesion problem may be resolved by warming the screen with a blowdryer, no need to get it hot, just slightly warm all over and smooth with a soft cloth as if you are applying a screen protector, it loosens the special sticky gel that attaches the digitizer to the LCD and usually helps in cases where sensitivity is sporadic or screen calibration returns wrong response. Check for any bubbling, although not seen when the screen is viewed directly, some may be noted at the angle.
However, in your case there are certain points that need to be pressed in order for it to work, so I take it, the screen works most of the time and the problem is intermittent, the corners that need to be pressed might be the ones where adhesion is not up to scratch.
Try re-assembly, if all fails - contact the screen supplier, faults can happen, especially in non-OEM parts.
Do keep us updated if you find the solution, I am sure all members can benefit.
Problem solved
Well over time, the situation changed so that the touch screen didn't work at all, unless I was pressing one spot above the LCD fairly hardly, at which time it worked without problems. Once I stopped presing the spot, it stopped working again.
So I tried opening the Uni and disconnecting and reconnecting the LCD FPC (which was located just under the spot that needed to be pressed), which seems to have solved the problem

Rainbow marks on screen

I was wondering if anyone can help me fix a problem I've got with my tp2. Basically the device turns on and I can make phone calls and use programs fine. However I can't use the touch screen at all, the hard buttons all work, but touching the screen has no effect.
When the screen is turned off I can see a rainbow pattern on it and it moves to my touch. This could be water damage but I don't remember dropping it in water. The water mark is red on the phone and battery, so it probably is water damage.
Just wondering if anyone knows an easy fix for this. Thanks for reading
Just had exactly the same thing happen this week. At first if I turned it off and firmly pressed my thumbs up the screen (as if I was pushing the rainbow marks to the edge of the screen) I could get it to respond for a while. Then it started to get larger spots and now I can't get it to respond no matter what I do...
If the touch screen is not functional, then you'll likely need to replace the digitizer. I would suggest purchasing the LCD/digitizer combos, as they are easier to install for first timers.

Screen not displaying anything at all

I know it turns on, it vibrates, and the notification light turns on and stuff, but the screen does absolutely nothing. The bottom buttons work fine. I dropped it on a tile floor screen first and it cracked, most of the crack being centralized in where the lcd ribbon is on the top left. The screen doesn't look cracked or anything. I tried opening it and reattaching the ribbon, but it didn't work. Any ideas on what could be wrong and how to fix it? Id rather not have to spend $300 for a whole new screen. Thanks

That screen is gone as you allready suspected. Take it to a service center or replace it yourself.
so nothing else could possibly be wrong with it? I just don't see how a cracked screen could do this
Go to the nearest Samsung repair center ,and pay 500 $ for it..Or replace it yourself but this means you'll lose the warranty.I feel sorry for you and for your N2..Why did'nt you bought a case?I actually have the Samsung Cover + and my dad dropped it .Nothing bad happened.
I called samsung and they said it would be $180 to fix it which seemed cheap but I don't know. I'll probably just sell it as is, buy a temporary phone, and wait for the s4 to come out. I had a case on it, but not the flip cover ones because they were annoying and didn't protect the sides at all. Plus this was a little more forceful than a regular drop.

White light spot on screen between sim and sd slots on T325

EDIT: Someone please move this post to troubleshooting, this is between my first posts on this forum, sorry.
Hello,
I have an issue with my T325, I have a white light bleed spot that is visible only on white or light pages between the two slim slots (in the middle of the screen but a bit to left). They are not dead pixels, many cheap phones have such a brighter spot.
I bought the tablet brand new 5 months ago, I have warranty for one and a half more years but it takes half a month or more until they see, repair and return the device if I send it in. (I haven't paid for premium service)
The spot appeared about 3 months ago but I told myself that I will not change my otherwise perfect screen for a brighter 0.3cm white spot even if it's a little annoying sometimes ( I had already exchanged two tablets until I got one without dead pixels or dirt inside the screen). I haven't dropped, pushed the screen on that point or did anything that could have damaged it.
However, at the beginning of this month i wiped my screen with a cloth that had something very hard on it and I didn't see and managed to get a deep 1 cm scratch (I can actually hook my nail in it) exactly in the middle of my screen and I didn't have a screen protector (who needs one on a tablet ? ). I am thinking on convincing somehow the service to change the screen because of the light bleeding. The two issues are unrelated, there is only one scratch on the screen clearly from a swiping motion.
Does anyone have an idea on whether the screen is defective or there is some strain in that point ?
Did anyone have a similar issue and managed to solve it ? Should I try sending it in ?

Ghost touching + Black screen

Dear valued XDA members
Greetings...
My Xiaomi Note 5 screen broke a year ago; I just woke up and found out:
- The screen is flickering
- Ghost touching
- Colored lines appeared
- Eventually everything went into black
Today I decided to repair it... A brand new original screen; so I went to the repair center and the guy changed my screen infront of my eyes.
When I got back to home, ghost touching happened again in a crazy way, I can't use the phone at all, moreover after reboot the screen became black, I can hear sound only.
I am not sure what is causing this, since the screen is new, and the software is fine.
Anybody has a clue what is this?????
I added photos of the broken screen, and a video after it was replaced.
Thanks in advance
Bad cable, connector, or pins not properly seated.
Loose ground. Failed mobo.
Try a hard reboot if you haven't already. Take it back to the tech, they may have a better plan.
