My samsung 55" rear projection tv will not turn on. When I plug it in, the musical chime sounds indicating it is turning on. The red light on the front will blink for a few seconds, then the tv powers off. No picture, no sound. The cycle just continues on and on until the tv is plugged in. A repair tech came out and replaced the power supply board. The tv worked for a couple hours and then I had the same problem again. The power supply board was replaced two more times before I was able to finally convince the repair tech that the problem was something else. He told me it was the digital control board. I was fed up with the service (and of not having my tv for over 6 months), so I told him I was going to try a different avenue or repair facility. Any help to at least confirm the issue before I try to get it repaired again will be greatly appreciated. Thanks in advance.
