We have had a Samsung HDTV for a couple of years, and up till now it has worked great. The picture began showing curvature, then started going out, reappearing, going out, etc very rapidly whenever the set was turned on. When the picture would fade out, the audio would get very loud and distorted at the same time. During the days leading up to this event, we would hear loud "popping" noises coming from the set periodically throughout each day. A cable repair tech was here delivering a new HD box, and when hooking up the new cable box, he got shocked mildly. He hooked up some instruments and told us the television set was "pumping out excessive voltage", way beyond normal limits. He said that instead of using the electrical house ground, it was using the cable tv coax to ground. What would cause a television set to "output excess voltage"? What might the fix be, and what kind of costs are we looking at?
There are 2 probable cause,...flyback transformer leak out and ur power supply goes high- v.not 4 to fix it too risky..both of this cost much..
