Tv turnes itself on at around 10pm if we are not watching it. It started at about 10:20 pm and seems to do it a minute earlier each time it does it. No cable is showing. Just snow on channel 23. I have to to press the cable button on the systemlink 6 a v remote and then turn it back off. The cable is hooked to VID1 thru a Magnavox MOXI.

Re: tv turns on by itself
If your TV is turning on by itself at about the same time each day you may have a timer activated, turn it it off, the TV's micro might need too be reset. To reset unplug your TV from the a/c outlet for at least 5 minutes.

If you're having the TV set completely turn off, then on, which will be accompanied by audible relay clicks, then this is a problem relating to bad solder connections on the main or convergence boards which will require someone with a sharp eye and savvy with a soldering iron. Most of the time, bad solder joints will be around the convergence amplifiers or in the high voltage section.
if it turns off and the timer light starts blinking you have a bad dm module, very expensive, it the light doesn't flash you have either bad front switches or something on the signal board, you can remove the speaker grill and disconnect both plugs and use your remote, this will disconnect the switches. if it still shuts off, you need baord repair, may be a bad solder connections, may be a chip/board needing replaced, you need a repairman and alot of money at that point.
after it warms up, and starts your problem. turn tv off. unplugg it. then feel the tops off all the caps for heat. also check the hv wires for leak and fluid leakage on boards. could be a possible broken trace or cracks in solder. possible in signal board.
I had a friend with the same problem. He had to clean the components and fans in the set. The accumulated dust had caused the set to run hot and a safety switch was the tv off. He purchased a few cans of compressed air and, as he blew the components and fans out, used a vacuum to capture the blown dust. Good luck.
