    Panasonic 50" Plasma A Board

    Thanks to help from posts and attachments on this site, I just got a replacement A board TNPH06921A for my TH-50PX75U and voila I have a picture!!!

    However it only fills part of the screen, about 41" diagonally to be precise.

    I think this board is also used in 42" plasma tv TH-42PX75U. What do I need to do get the full picture?

    ps. The board p/n is exact match for what came out of my set.

    what revision did you get? TNPH0692 will be the PCB , 1A is not relevant but there should be a revision suffix usually 2 letters which is important to match the correct board for the size of the panel. Does sound like you got a board for a different model.

    Have a look here for the different versions that apply t each panel variant

      My old PCB was Suffix "AC".

      The new board is "AB". Does this mean the new board is not compatible with my 50" TV or is there a fix?

          well if you're stuck with the board and can't return or locate AC the only suggestion I have would involve eeprom swapping. What you'd have to do is get the serv manual for both then compare the eeprom numbers used in each. find the ones that differ and swap them from you're old board to the new one and hope that sorts it. It should as the only difference is the data loaded on these. You won't have to do all but I'd expect 1 -2 chips will be different without looking at it.

            Unfortunately, the only fix is the correct suffix.

            You'll have to keep looking. Ebay, ShopJimmy, Google. You can try to send the suffix AB board back to where you got it.

              If it's only A board been changed these are what to compare to the 42

              this is what should be on the Ac version. Find the difference and swap those, the numbers are what are important.
