Question about Panasonic PT-51G44 51" Rear Projection Television
My 51" Panasonic TV has blown the PC Board/ Power Supply (Part # TNP2AA045S) for the second time. I am wondering what keeps causing this to happen. When the TV was working, there were faint wavy lines on both ends of the screen.
It would seem that a surge protector power strip would also fix your problem.

If it blown the second time, you should start to look for a bad or leaky electrolytic cap. visual check first if there is any deformed cap w/c is it's almost bursting on the top, try near the H-output, look for bad ones and your problem will be gone. hope this help

What hendrix is saying is there is a small disc device called a thyristor that goes across the ac line input and an power surge we call it will be stopped there. This thristor is nothing more then 2 silicon diodes back to back with a reversing current of 150 to 170volts rms. Now how this works is if there is an overload or power surge comming intop your house or apartment this devise will conduct at the voltage they are rated for and short cuicut and blow the main ac fuse. Every thing I have thats electronis I install these diodes and havent had a blow out with my electronics since then but have had other things that plug in like the toaster or smething like that..

Power supply can get blown from high-voultage. TV has a mechanizm that shuts it off in cases oh too much current through the system, in order to protect it from getting blown. its only a shot in the dark here, but maybe this mechanizm is broken. use a DMM and measure the voultage in the system, in order to determine if it is normal. I assume you already checked for the obvious blown fuses, bad solders etc. sorry I couldnt be more helpful. good luck.
