Facing TV Problems? Ask a TV Technician.
Hello, I'm Shahid.Sorry to hear that you're having trouble with this but I'll do my best to help.
- 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?Thank you.
OK, is the TV connected to HD cable box for channels?
Have you tried to reboot cable box? disconnect cable box power cord from power source/ wall socket for 5 minutes, reconnect the power and let cable box reboot that may take few minutes and check picture.
Please reply back with the result and if problem resolved then a positive rating to answer would be highly appreciated.
