They are all LG 40 inch above a bar. 6 mos old.

Technician's Assistant: Does the TV menu work? Do you have the same problem on all sources/inputs?

I have 4 Comcast boxes feeding the TV's it's the same on all boxes but some TV's are fine

It is just random

Thank you for your question, my name is ***** ***** I look forward to assisting you.

Please note, a rating is only needed when we are finished.

Can you please remove the power to the TV (so unplug it from the power socket).

Then on the actual TV, hold the power button for 60 seconds then release.

Then wait 10 minutes, connect the power again to the TV, turn it on and tell me please if it is now operating correctly.

Let me know the results please

Comcast box. 4 of them. Denon receivers. RT1 remote control system

If you connect it to another device then the comcast box, such as a DVD player, how does it then look?
