I've had this tv since towards the end of Jan and have had no problems till tonight...All of a sudden it won't pick up 3 channels AND It won't turn off... Anyone had this problem before? Any idea how I can get it turned off short of unplugging it and maybe ruining the bulb? It can't be storm or power surge related as it's hooked up to a Monster HT UPS 1000 and a Panamax surge protector...
