My TV (connected to Xfinity HDTV box) periodically goes black.
I don't think it's the cable box, because I can rewind the program, and the black screen is not part of the broadcast.
I've seen some other posts on this, but no definitive fix. Is this hardware issue, or fixable with update? (I think I have the latest updates for this TV.

My QLED purchased in Oct 2017 screen goes black. It starts off black and the only way I can get it to work is to unplug the power cable about 10 times and then if finally comes on however it still goes black off and on while watching. It seems to be gettin worse as the months go by. this was happening last year and I assumed it was the cable box but then it started happening on all inputs and now it happens all the time and I cannot even turn the tv on some days.
