Check your componet connections to the TV, Componet cables use green,red, blue and red and white for audio, check the green cable go see if it came loose, because if it is the picture will be B &W.
This could be a poor connection with the LVDS cable which runs from the main video processing board to the screen, or a fault within the video processor on the main board. Worst case scenario is it could be a fault with the screen itself.
One of your "X" buffer boards is defective. In Panasonic plasma tv's they are located at the bootom of the set and connect directly to the plasma diplay panel via a thin ribbon cable. The board you want to replace will be directly in line with the discolored vertival line in the picture. The part number is on the circuit board and usualy starts with "tnp..." or "txp..."
This is a result of poor conversion of a SD signal on a HD channel. Go into your settings and adjust the h/v settings to move the line off the screen. You can do this with a combination of v-position or vsize.
There are individual drivers for each line of plasma cells in the display (horz. & vert.), but they usually are an integral part of the display module that can only be repaired by the manufacturer. A new 42" HD-ready set with more features can be bought for 50-75% of what was likely paid for this one. The cheapest thing to do is learn to live with it. (That's what I'd do until the set got worse or the prices got even lower.)
