Getting 4 blinks from power button LED..tv won't turn on...keep hearing a reset switch ticking in back of tv...It used to cut on after about 2 resets ...now nothing. And prior to this matter, after a couple of hours of being on, tv started iving weird pictures. When cuts on picture is fine, just can't get it to turn on. I tried to unplug it for a few in. Please Hlp!!
