Why no picture or sound on my virgin tv screen


Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

Blank white screane. When i open the camera to take pictures the screen doesnot show any thing it just blank white . the zoom and other thing work


Sounds very strange, hope it isn't serious. Maybe try removing and replacing the batteries. Sometimes a reset helps problems like this. I have the same model.
