I know you said you've reseated the ribbon cables but have you reseated all of the ones going to the X-drive boards? (Usually on the bottom, and sometimes also on the top of the screen.)

I also am having the same problem. I replaced the Y buffers, the main board, the caps in the power supply.

The Y buffers would not let the TV come on. It comes on with a prefect picture but I have the horizontal black lines. Were you successful re-seating the X connectors?

Thank you

Targa, that is a pretty typical symptom of the connectors not being seated correctly. It's pretty hard to get right. You'll just need to remove them and try again.
