Hello, I'm Shahid. Sorry to hear that you're having trouble with this but I'll do my best to help but need more info to troubleshoot the problem.
- Could you please get me the complete model number written on back cover or side panel of TV?
- What video devices/ sources (such as cable box DVD player etc) are connected to the TV and does the problem occur on all video input sources?
