Horizontal lines	Can't Post

My Hitachi P50H401 has horizontal lines in the picture.Starts out abot 6 at the bottom then skips about an inch and there is about 26 lines,skips again the same amount and there is about 12 lines.I have replaced power supply,Y sus and upper and lower Y drivers.I've spent more than I should have but now I want to find out what it is.

VERY carefully re-seat the ribbon cables going from the panel to the Y-buffers.

These sets are the most difficult to seat these cables properly, and the easiest to blow the buffers if the cables are not seated correctly.

Thank You Thank You,I paid money on the internet for people to tell me it was the panel and couldn't be fixed.I've now learned one more thing from experience horizontal lines can be caused by upper and lower buffers not seated good.Don't think I'll have to write this down I'm sure I'll remember this symtom
