Toshiba 57H82 Projection tv: sudden "off-on" problem

I have a Toshiba 57H82 57" 16:9 HDTV-Ready Projection TV. After about and hour or so the tv will shut off then back on in rapid succession. Then after the first occurrence the frequency, will increase incrementally until it happens about every 30 seconds or so. If I turn the tv off for a few hours, the whole sequence starts over.

Sounds like a bad tuner/decoder on the Qam analog side of things. You can bypass this with a Clear qam converter box or a analog to digital tuner box or simply having this repaired upwards of $200 bucks.

Thanks for using
