Yes, I checked the power supply voltages and they are exactly right on. I just received the new Y sustain board and installed it. Still a few sparkles but almost gone. Of course this is on broadcast stations. I hooked up a blue-ray player and pictures looks perfect no sparkles at all. Also with the replacement board (y sustain) the lines don't pair up anymore, looks pretty good. I think I will put it back together and see how it goes.
