My Philips plasma is a replacement for a broken Akai edtv.
The difference in picture quality is amazing, however, there is a thin white line that runs top to bottom, about 5" right of center.
Is there a simple fix?

Vertical lines aren't generally caused by a bad panel, horizontal lines are...remove the cables going from the Tcon board to the panel, both at the tcon and panel, wipe them down and re seat them and see if that takes care of the issue, if it doesn't replace the timing board, I don't think this is a panel issue
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..."
It will burn into the screen overtime. The Akai units have a resistor on the address board that feeds the PDP that usually has a crack in the solder on one or both ends of it. There are about 4 address boards that are right below the panel itself and the suspect one is the board right below the line that is appearing. Have someone with solder skills repair it.
