Dear JA customer,

 

Thank you for your Just Answer question.

 

So that I may further assist you, I need some additional information.

 

Are the stripes vertical, and across the entire screen?

 

Can you see any menu?

 

Thanks

Thank you.

 

There are several possibilities here including the Logic Controller, Vertical Buffer's and the PDP.

 

A common fault is the Logic Controller board, it addresses the vertical Scan Buffer IC's. An experienced technician would first inspect the ribbon cables and buffers for any burnt spots, if the cables are burnt then the PDP would be at fault. If no burnt spots are found, then reseat the ribbon cables to the Logic Controller board and replace as necessary.

 

You can view a picture of the Logic Controller board at this link. The exact one for your set would have to be matched with the part number on the board.
