Seems like it wants to scan channels all the time . As soon as we turn it on. It also shuts itself off in 60 seconds after scanning

Hello, my name is*****'ll be happy to assist you. I need additional info about TV to troubleshoot the problem.

- 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?

- Is it coax cable plugged into antenna pin at back of TV?

Thanks.

We were told to turn booster off for hooking to cable. I have tried both ways with no results

It seems TV tuner mounted on main board has failed for some reason that is why it has become unable to receive signals through antenna or cable. Swapping the main board will help to resolve the issue, required main board is available at following supplier for $40
