http://www.tvrepairinfo.com/ Sometimes a seemingly difficult problem has a simple solution. Before getting carried away and replacing perfectly good circuit boards make sure you check the simple things. In this case we started thinking the Plasma TV panel or lower address board was bad, but further investigation revealed the ribbon cable needed to be re-seated.
This was a Samsung Plasma TV model number PN50A550S1FXZA. Other numbers related to this TV are LJ41-05571A for the Y-sustain board. and LJ92-01531 was found on the logic board although both none of the boards had any problem.
