I guess that is a Verizon Cellphone. It is most likely that the LCD has lost grip or contact from the main board or has gone bad . 1. You may disassemble it and check the LCD contact points on both the board and the screen...detatch attach it firmly or
2.You may have to replace the LCD completely.See what the LCD looks like here ....

I hope this helps you.
Good luck !

Is there a simple reason why the screen on my samsung mobile has gone blank.the phone can still turn on and off and keys still make sound when you press them as they normally do but nothing on the screen...


Hi,

The problem is from the flex that connects your screen to the phone's main board. This flex must have worn out that's why your screen is not displaying any picture.

The problem is common with flip and slide phones. The flex gets worn out as a result of constant opening and close of the flip or slide phone.

I would urge you to replace the flex and I am assuring you that your screen will display picture again. You might also be lucky to find out that the flex is not well fix, that is, it may have loosed contact.

If you cannot change the flex yourself, maybe you should take the phone to a local repairer within your vicinity, so that the flex can be fixed/replaced.


Take care.

When i turn the phone on the screen is completely white. I can't see anything and therefore I can't text or call or do ANYTHING on my phone.


Hello,

The phone is a flip phone, it means the flex on the phone screen of your phone as gone bad and will need to be replaced.

all you need to do is just to replace the flex and your phone screen will come up.

Screen gets distorted and turns white


Hi,

The part that is bad is the Ribbon flex cable that geos from the main board to the LCD board. Over time the cable becomes chaffed and will lose continuity between the traces. It can be fixed with

Tessco Part #: GH97-07715A

It does need to be soldered on the LCD side.
