i opened up my uni the other day becasue my screen was not working but the uni its self was as a answered a phone call.. i found that the silver casing around the flex cable had broken and split the wire inside is all coming apart i guess i have to get a new one but is it easy to replace and where could i get a replacement cable
cheers joe
I tried taking out the lcd cable but accidentally broke the pins connecting it to the motherboard. Is there any way to fix that? Or is the touch screen pretty much done for. Thanks.
Hello,
I would like to know whether this problem (broken flex cable connector) is fixable or not? If yes, can you guide me.
Thanks.
Hello,
I have a LG D802 EU unlocked and noticed that it wont charge anymore, so I ordered a replacement flex cable. Sadly, I ordered one for the D801, which I didnt notice at first.
So I replaced the flex cable, it charges again but the problem is that the touchscreen does not work properly anymore (sometimes there are 'ghost touches', so it physically still works).
After a lot of googling, it seems that the problem is that the connector on the right side of the flex is responsible for the screen and is the part that seems to make problems. [Red on the picture]
Another problem is that the one connector on the left side does not fit, as the 'hole' is bigger on the D801 model. [Yellow on the picture]
Is there anything I can do? Maybe using parts from the original flex cable I have, like only the upper things?
I have tried unplugging/replugging the red connector already.

It charges. The alarm goes off in the morning. But the screen doesnt respond and at first it was flickering toward the bottom. Now its black.
Ive torn it down about 50% and dont see anything wrong. The connections seem fine.
There are three photos on the phone I must have for work. Must.
Ideas on repair? Or data recovery? When I plug in the usb to pc I hear the noise and I know its asking 'charge', or 'transfer files'. Without screen response I can do nothing.
Any assistance to get it working or data recovery would be hugely appreciate.
Edit: The glass is not cracked or broken. Ive dropped it literally 100 times. In the first month I fell and sat on it breaking the back cover. I replaced that. That was 2 years ago. Some background of the device.
You destroyed lcd, so replace it or use o Mouse with otg usb c adapter and try to change connection to file transfer

otg usb c adapter. I have the usb c cord. otg adapter is something I need to get I take it. Thanks for responding.
The important thing is you're ok. Lol, all my bikes are worth more than my phone... I hope yours isn't too damaged.
Try disconnect/reconnecting the battery and reboot; a hard reboot.
If you're lucky a ribbon connector, or ground pathway was displaced.
Either the display is damaged and/or the mobo.
The BGA chipsets can't have their solder joints inspected and even finding visible solder cracks is difficult on surface mount components. High G impacts and excessive flexing can internally damage chipsets, solder joints and multilayered PCBs.

A damaged lcd will flicker, not respond and go black? The glass is not cracked or broken.
The glass and digitizer are one piece it appears.

So far Ive found no ribbons disconnected. Ive inspected as close I can all visible connections. Nothing stands out.
A lcd arrives tomorrow. So well see if I get a response when I plug it in...
Like tv, if you punch lcd it won't shatter, the crystal will flood or it just flicker, so yes it doesn't have to be damaged visibly to be broken

The battery may have been damaged, keep that in mind. Make sure the phone has enough voltage and current to run.
XDA is awesome. You guys are the best. You may have thwarted an injustice. Saved the files. New lcd heated and I have clamps on it so it seals, hopefully. The frame was slightly bent which was making it hard to keepit on. Im on the home stretch I think.
edit: What to do with an old lcd...
Next project - unbricking an lg stylo 4 with the ch.co message.

Practice makes perfect... a template would help.
