The above set came in dead. Customer said it got harder and harder to turn on, so they left it on all the time. (Never heard that before, have you? 
)
Anyway, I found and replaced half a dozen 3300uF 10V caps in the SMPS, hit the switch and it fired right up, but no celebrating for me.
There is a picture, but it has a lot of reddish sparklies in the main viewing area of the screen. There are fewer in the top part of the screen, and none within 3 inches of the edges of the screen on all 4 sides. The bottom half of the screen has a very definite pinkish tinge because of the sheer number of them. Also, there is a reddish line across the screen right at the half-way point, but it fades out toward the edge of the screen too.
I think it's important to note that the TV does display a picture, and most kids think it's a fantastic TV because it has a big screen. They don't notice the red. I do, and the customer will.
Part of me says "Z-sustain board is causing the sparklies."
Another part of me says "Nope! Y-sustain, since there's a line!"
"But the line isn't complete all the way across! Z-sustain".
I'm feeling like I'm multiple personality here. Anyone seen anything like this? Any suggestions? And sorry if I didn't search properly. I did punch 50PY3D into the search and got nothing. Going to try a few other search terms.
