Question about Cell Phones

1 Answer

I replaced my lg cu720 lcd screen and now there appears to be no display what so ever. The screen simply glows black. All the sounds and button lights on start up work.

    Yes, the procedure was pretty much exactly like that. The thing is, that when I even try to plug my old LCD back in... the crack glows white and the back of the old LCD glows pearl just like the new one. It seems that the connection if probably messed up, but no matter how many times I retry everything, its the same result.

    Before I tried replacing it, the cracked LCD would still display colors. Now however, it shows nothing when I try to put it back in.

Hrm, it sounds like one of two things is going on, either the cable connection to the new LCD is loose or the actual new LCD is dead. Just to verify, did you go through the steps similar to what is found on this site:

Did you get the LCD from somewhere that will allow you to return it for a new one? I've definitely seen my fair share of bad LCDs right from the factory.

Thanks much, hope this helps!

    Does your original lcd have similar issues to the new one, or it has a crack in it but you can tell it is displaying colors and info? I am still leaning towards a possible bad new LCD. It definitely isn't all that uncommon.

    Oh I see, so the old one is doing a similar thing now? It sounds like the actual LCD connector is possible damaged on the mainboard of the phone. They are extremely sensitive and really aren't made with replacement in mind. You may have to get a new mainboard for the phone or just replace it overall. Hopefully you can still return this new LCD. Sorry about that =(

Screen is black but it still works


Their either is no link between the PCB and the display/screen or the display/screen has worn out. Try getting the phone serviced at a nearest LG service center.

No display in my lg shine cu720


What happened in the first place to make your lcd screen go out? there is a chance that the problem was not the screen, but the phone it self. did you drop it in water, or jus cracked screen?

Replaced the screen but there is no image coming up, just a lit up black screen.


if you could see any image from the broken lcd before changing it so your new lcd is not working or no installed right
and if not you may try the cable or the hard shock that broke your lcd effected the main board
