I've got an xbr55930d. It currently has backlight,sound from menus, but no picture. Replaced the main board, DPS/frame rate conversion board, and also tried a new T-con. After further testing the T-con to panel isn't getting voltage. Avdd is at 0v. Jumped twelve volts to avdd and got the panel to react and display verticle grey lines. I'm not sure how to test the boards on the panel and repair them.

I think the same thing is happening with this T-con described in the linked thread. The T-con is shutting down due to a failed component on the T-con or panel boards. I'm not ruling out panel at this point.
