This Magnovox TV has been working great, just recently the little green "AV" box and green "stero" box shows up on screen and the picture gets wavy and the red and green colors seem to dominate the screen. First we thought is was a bad AB switch box we are using between the cable box and the DVD player, but I unhooked the switch box and ran the audio visual wires directly to the TV and the same thing happens. The TV will work fine for a while and then all of the sudden the picture color gets bad and goes away. My wife seem to think that jiggling the wires in the back seem to make it better.
