Report "My RCAPS56670 television comes on and sometimes after its been on for a while the picture distorts, I then turn it off and turn it right back on and the picture is perfect the longer its on the shorter the periods are before it starts doing this every couple of minutes. Sometimes when I first turn it on we can get through an entire movie, but when it starts messing up the picture it just keeps getting worse the picture darkens from the top and the bottom almost looks like an hour glass shaped picture lying on its side, so we shut it off and turn it back on and it works fine for a few minutes then the picture does the same thing how do I fix this problem?"
