Display screen intermittently goes to scrambled colors its a Lg Rumor


Hello first of all

Hey man how are you doing i used to work for sprint as a tech you need to take it to your nearest
sprint service center. Once your there tell the repair tech that you need a flex cable replaced.

A flex cable is a cable that runs from the main board to the lcd screen and the problem with the rumors flex cable is they were getting scratched when you slide the phone open and closed.

All that being said its free to you to have it replaced as it what sprint calls a known issue so even with no phone insurance it a free repair and takes about 15 minutes if there not busy. I posted a picture of the part below.

could you please rate me 4 thumbs up if it helps you thanksjamiesturm29_0.gif

I Have a LG Shine Cu720 and the screen has stopped displaying anything, what could be wrong?


Hello,

The problem is from the flex of your phone.

The flex is the mechanism that controls the sliding of the phone, and it also carries information from the board to the screen.

Once the flex if faulty, there would be several kind of problems coming up on the screen.

Once the flex is fixed the phone will be in good condition again.

Take care

My lg cu720 powers up but nothing displays on the screen


Hello,

problem can be solved.Since it is a sliding phone you need to look out for two things:

the flex of the phone
and
the screen of the phone.

The flex.It connects the phone board to the board of the screen that makes the screen to display.You can loosen the phone to check if the flex have shifted and it needs adjustment for it to display.

The screen can also be the course of it not displaying. Lose the phone and check with another screen to see if it needs replacement or not.

I would advice if you do not have the knowledge of to lose the phone ,you can take it to a mobile engineer around to prevent further damage.

Have a nice day.

LG display is completly black, however the phone works


The problem is either in the the flex ribbon connector, connector terminals or LCD itself. Disassemble the unit then check the flex ribbon connector for any crack or damage. If no apparent damage is found, clean both the flex terminals and the connector terminals. Resoldering the connector terminals is also suggested. If no result, LCD is damaged, replace it.

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?

Screen blank and slide lose


Hello meashaw...
Looks like your phone's flex is damaged. You bring it to LG's authorized service center and they will fix/replace its flex for free if it's still covered by a warranty. That's what I did for my slide phone also (other brand).
