Hello All - just picked up a Samsung 50" plasma free off CL. Owner said it "stopped working during the recent storms" so I'm guessing lightning strike, but who knows. I've repaired multiple LCD screens of various sizes, usually just some capacitor, resistor and/or transitor replacements. Plasma is new to me, and looks a little tougher.
I plugged it in, and immediately the front status light came on blinking blue, and I heard the standard "boot" sound/jingle as if the TV was coming on. This seemed to be a positive sign. Then after about 10 seconds I heard electrical discharge sounds, zapping sounds, and quickly unplugged it. Before I did, I saw a bright flash from the back. Bad, of course. None of these symptoms were mentioned by the original owner, only that it "stopped working".
I popped open the case, and checked the area I saw the flash first. From the back, it was the upper-left area. I took a look at the Y-Main, and as you can see from the image, the components there were completely obliterated. I can't even tell what was there. Reviewing the service manual now and starting my testing.
Can anyone provide some general direction? Based on what got fried so far in the image, am I already in too deep to bother trying to repair at a low cost? Off to do some testing - advice is welcome, thanks!
