How do I open my lg vx8700 to replace the ribbon connector? Should it be replaced or can it be repaired or cleaned?

It cannot be cleaned or repaired, the flex cable must be replaced. This is a very difficult task as the entire phone needs to be disassembled. There are many small parts to deal with not to mention your new flex cable is very fragile and can be easily damaged in the installation process. Its best to have a tech handle this one unless you are very brave....... lol

My lg vx8700 has only been used for a month and the screen goes blank on it about 7-15 seconds after I flip it open.


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.
This is a common problem 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 will suggest you replace the flex on the screen of your phone to solve the problem.
If you cannot change the flex yourself, you can take the phone to a local repairer within your vicinity, so that the flex can be fixed or replaced.

Take care.

Compatibility with LG VX8700 - connects but won't work when button pressed

Seems I may have the same problem, I just returned the first Jawbone, second one is displaying the same problem - it pairs but then won't recognize or interact. Sad if it's my phone.
