Samsung pn50b450bdxza version s602 has a white bar going down the right side.

SOURCE: I have a white bar on the right side of the screen.

This is caused by either a bad address board (low $) or a bad plasma panel (high $). The only way to know is to replace the corresponding address board and see if it repairs the line. Hope this helps.

PiP or bad connection. disconnect the set with all cables and reconnect and see what happens
