Hello
TV Technician: Shahid, Technician replied 4 months ago

Hi, lets start troubleshooting..

- 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?

It's only on the tv. Stereo, fm receiver DVD drive all ok! Just happens on the tv!
TV Technician: Shahid, Technician replied 4 months ago

OK, you mean problem occurs when watch TV channels, is this correct?
If so, is the TV connected to cable service or hooked to antenna to get local channels?

We are on cable service. That is correct. The hum only occurs when we are watching tv!
TV Technician: Shahid, Technician replied 4 months ago

Thanks for the info.

Problem could be coming from cable box as TV shows no issue when watch DVD etc that means TV itself is OK and problem is within cable box, lets try easy thing first that might work..

- Have you tried to disconnect TV and cable box power cords from power 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

Due to the nature of the problem, it may take a few tries back and forth before we finish the troubleshooting and fix the problem. If this fixes the problem, please rate 5 stars.

If above suggestion doesn't fix the problem, please reply, and I will return your response as soon as possible.

Rating negatively does not instigate a refund, but you can always request one from me if your problem is already solved.
