Horizontal Lines on screen, any ideas?

Block Image

Hello

I am new to repairing so bare with me.

As shown in the image, the screen has horizontal lines and i have no idea on how to fix it. I have taken it apart several times and given it a very thourough clean. The circuit board looks brand new, soldering is fine, pathways are fine. The only thing i can think of is that there is something wrong with the screen itself and the rubbery things that the screen is attatched too. I have no clue on how to fix something like that and have found no repairs online for it.

Any help would be appreciated.

Cheers

Tim

Hi

Thanks for the reply and advice. I have tried everything you suggested but still to no avail, but i did find out that you can remove those rubber strips from the screen very easily to clean them. I have attached (not great) pictures of my VMU to see if anyone may have any ideas in the future.

Cheers

Tim

Hey there,

It looks like an issue with the connection from the screen to the board. The only thing that's really holding the screen to the board is the plastic case, so try tightening the case screws a little bit. Otherwise, try removing the screen (It's not soldered in place and should pull right off) and cleaning the zebra strips and contacts on the screen and board with 90% rubbing alcohol.

best of luck to you
