Hello,
It seems that flat cable which connects the slide-out screen is broken: the touch-screen doesn't work, and there's a white lines all over the screen while opening the device.
I've made a call to my local service center and they said that I need to change the whole touch screen because the cable is glued to it.
Is it right? Is there another way to fix the device rather paying $300 for a new screen?
i have also the same problem For my PDA2K , my flat cable which is comming from the screen under the slider is broken ,, half of the cable , i have the orange cable ,, is there any way to fix it
Thanks

I had the same problem on my Universal and opened it to find out what happened.
I found the cable connecting the LCD and touch screen completely twisted.
Someone has played with it turning the screen in the same direction for many times without unscrewing it every time.
I manged to fix it partially soldering some wires that had gone loose.
Some wires were impossible to handle so I need a new wiring cable (it's a bunch of single ultra-tiny wires).
Now screen, mike and headpiece work again, but not the touch screen.
Do you have any idea if such a spare part can be found anywhere?
Possibly that would solve also your problem.
Who can have spare-parts?

Hmm....
Actually, not only the flex cable is originally twisted and looks funny out of the factory, you cannot turn the screen in the same direction more than it should be turned (e.g. from opened clamshell it only goes 180 degrees clockwise and cannot be turned anti-clockwise other than returning into its original position), it is stopped from turning by the way the hinge is designed. It is done specifically to prevent just the thing you described.
Generally even when some wires detach, the cable still performs fine, as the wires are not isolated and bunched together, as long as they do not detach from the connector itself. The fraying can happen when the flex cable is reinserted into the main case too roughly or one time too many, as the opening is fairly small and both cables need to be bent a certain way to fit through and pulled through in a particular sequence. Your problem could be caused by a faulty digitizer, it is connected to an LCD and if LCD performs fine, yet you lost sensitivity, the problem is not with your flex cable.
Cables can be purchased on Ebay. And so can digitizers (they are around $17-$20, but you need soldering to get them fitted to your LCD).
Hi all,
I just replaced the flat cable of the phone, the one that connects the two phones parts together. The phone was having issues with the display when going to landscape-mode and the mic stopped working recently so I replaced it following this guide:
Anyway the display problem is solved by replacing the faulty flat cable but only a new problem occured.. The screen does not respond including the capacative buttons and the big scroll button, its looks like the whole display unit with all its buttons is not working. Any suggestions? I will be taking it apart again and check if all cables are well suited but besides that someone might recognizes the problem
Thanks in advance!
Could be bad connections, the new cable you put in could be bad or by coincedence the digitizer went

Hey guys, I am having problem with my One X.. I bought new replaceable LCD screen and digitizer yesterday. I ve assembled it without any problems, even with connected LCD/digitizer and everything worked fine... But When I tried to screw the motherbord to the house frame, suddenly the brightness of LCD starts "blinking" (lowering and raising).. I think that this issue can cause lcd flex cable...
Can anybody tell me the voltage of this cable/connector or does anybody have any solution for this?
Thanks in advance
Edit: Found some article that says, it could be defective LCD Screen FPC Connector.. Can anybody agree?
After display replace speaker won't work if mother & daughter board touch each other
Yesterday I replaced the screen of my LG G3 titan black (D855 screen) everything worked perfect but after reassembling and turning it on the android showed me that the headphones are connected (which they are not) and the speakers therefor doesn't work. Also the mic is not recording.
If I disassemble the bottom 4 screws and push the mainboard away from the back of the phone towards the screen using the micro usb plug the sound is working.
I looked closer at it and realised that as soon as the mother board ist touching the small daughter board the headphones show as connected.
I wonder what I can do about it?
Put a non conducting tape between the two boards?
Remove the daughter board?
Anything else?
