TRIPLE IMAGE THE IMAGE IS TRIPLE 3 COLORS IN THE SCREEN

Watching tv turned off turned back on later 3 hours then sound no picture.. if you walk up close you can see outline of picture faintly

This would be the decoder/tuner board giving out, Your going to need to take it in for a replacment of that board.

you can try to unplug it for a while and see if it resets but i doubt that will cure anything long term. Proscan is known for this issue and have been known to have bad decoders in them.

Thanks for being considerate and leaving a ratings and feedback today.
