Hello, my name is ***** ***** I'll assist you. I'm sorry you're having trouble with it.
I need additional info to troubleshoot the issue.

- How old is the TV and how long it have had the problem?
- What video devices/ sources (such as cable box DVD player etc) are connected to TV and does the problem occur on all video input sources?
Thanks.

Hi Shahid
The screen is about four years old.
I has a DVD player plugged in but unplugging that does not alter the problem.
I've had the problem for about three months
It is only the turner that is the problem

Thanks for the info.

Have you tried to restore default settings in TV and run initial setup to see if it helps?

Sorry to hear that, it seems tuner mounted on main board of TV has got internal failure and causing this problem. Either replace main board of TV or get set top box that would have builtin tuner (also known as external tuner box) and hook it to TV, plug the antenna/ aerial into box, run channel scan to keep watching channels on TV through external tuner box. This way you wont need to take the TV in repair shop for main board replacement.

I trust my input will help you out. Please feel free to respond if you have any additional questions.
