The replacement YSUS board came in today. I checked the fuses and did a visual inspection...all looks good. Upon installation, still no picture! When I turn the set off, there is an ephemeral, barely perceptible flash on the panel. I also noticed that all three heat sinks on both sustain boards don't get nearly as warm as they did before, and in particular, the larger of the two YSUS heat sinks stays stone cold. No fire or smoke, though! Upon closer examination of the new YSUS board, I found the small surface mount fuse near the bottom row of capacitors to be ...odd. With my multimeter, it tests differently than good, but not completely open. I guess this is the problem? I'll probably ask for my refund now, and hope a better board becomes available.
