I have only the bottom 1/6th of the screen functioning even after replacing the Y Main and buffer boards. I'm thinking that before I throw any more money at this set that I'd like to verify that the PDP isn't bad. All voltages are good.
Here's my idea:
Remove both Y boards from the chassis but provide solid grounds from the boards to the chassis. Move the 6 buffer ribbons up one position, leaving the top ribbon disconnected and no input to the bottom of the screen. I know the bottom ribbon is providing good signal to the PDP. If the image moves up the screen by 1/6th then I know the PDP is good.
Will this work?
