Hitachi P50S601 problems.

[Blabel182]

Hello all, I was given a Hitachi P50S601 plasma for free with bad caps on the PS board. I replaced them and now the TV powers up and has great picture on the top half of the screen, but the bottom half of the screen has black lines going through it. My first thought was the lower buffer board. It was cheap, so I replaced it. Still the same problem. I am 100% sure that the ribbons from the panel are fully seated. I'm beginning to lean towards a bad Y-SUS but wanted some opinions first.

Pictures of the boards ?

Here's some pics. The Y-SUS, SDR-U, SDR-D, and what the TV is doing. Like I said, the SDR-D has just been replaced with no improvement. If I play with the pin 5 on the ysus board where the sdr-d board attaches with a small probe I can make the lines lighter and darker but they never completely go away.

Does seem like Ysus to me.
