Help. Antenna/Cable switch

[captpar]

I have no power to my OTA/Cable switch. Can somebody tell me where that switch terminated or starts from , is there a box behind the TV that these 3 wires start/terminate from ? Checked for a blown fuse first but only fuse marked antenna was good but I changed it out anyway . Multimeter showed no power to switch. Of course wires disappeared into the walls. Will pull front TV this weekend to see if these wires appear somewhere behind TV. Any advice at this point will be greatly appreciated. BTY the TVs are stuck in the antenna position vice cable. It doesn’t effect my satellite.

The picture shows a small black button - the ON/OFF switch. When it's ON there should be a small pilot light lit on the wall plate. If that switch doesn't light the light, pull it out and check for 12v going to it.

Pull the assembly from the wall, fuse on many are on circuit board.

Wow your fuses an circuit breakers are marked, I think the refer, furnace and AC are the only ones in mine.
