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 - Have you tried to unplug TV and cable box power cords from wall outlet for 10 minutes to reset, replug back in, let cable box reboot that may take several minutes and check?If not yet, please try it now and reply back with the result and if problem resolved then a positive rating to answer would be highly appreciated.
OK, I hope rebooted the cable box as well.
can you recheck TV model number as UN48EH5300FXZA seems incorrect and I'm having hard time to get related manual for troubleshooting purpose.
