magnavox 20mt1331/17 top of pic. folded over&shut down
the top 10% of pic. is folded over onto itself and the set turns off after an hour or so. I have to push the power button twice to turn it back on and about an 1/8" of rainbow colored lines appear about 25% down from the top befor the pic. comes back on but once it turns off it woun't stay on long. Thank you for any info.
