Question about Samsung HP-T4254 42 in. Plasma Television
Your Y-Buffer Boards are going bad. There are 3 boards here. The Y-Buffer Upper controls the Displays top half, the Y-buffer Lower controls the Bottom half and the Y-SUS/Main controls those 2 boards. Usually when one goes they all go. The Boards are located on the far left of an opened set. They are the skinny boards going up and down. THey are connected directly to the Y-SUS on the right. However you can have good buffer boards and a bad YSUS. I have replaced the buffer boards on sets only to discover it wasn't those boards it was the YSUS
