Hello, I'm Shahid. Sorry to hear that you're having trouble with this and I'll do my best to help but need more info to troubleshoot the problem.
- Does the screen glow/ show backlight or any graphics appear when turning TV power On?
- Any idea how old is the TV and how long it has had this problem?

I love this site! $9 instead of a repairman or new/used frig can't be beaten. This older woman will worry less now that she knows about this site. Bless you all.
