FIRST, its not the sleep fuinction. Checked that and its off. It doesn't happen with every source. The xbox works fine, the VCR Movies work fine. It only does it when the Dishnetwork is being used. Here is what happens: Turn on Sat and TV. (Sat rec. is wired directly into TV, TV is a 37" Panny HDTV, about 2 years old if that) we did this several times, TV will stay on anywhere from 5 minutes to 30 minutes and then shuts off (Never the same always vary's). It must be unplugged before it can be turned back on. Any suggestion or reasons why its doing this?
