- Thats the problem, there is no picture what so ever. The screen doesnt come on at all. Do you have any idea wich board on it could be bad? I have had it for almost a year, but I bought it this way. The person I bought it from had only had it 3 months when the screen stopped working.
Study the screen at several different angles; you should be able to see some ghostly images if the video chain is OK.
If you can see this, either the backlight supply or fluorescent light source has failed.
