    A Tale Of Two Main Boards, Phillips Plasma

    I had a Phillips Plasma (don't have the model number handy) that I did something stupid with. After changing a bulging main cap, I plugged a connector from the power board to the main board in the wrong socket and was rewarded with a fine wisp of smoke coming from the main board..

    OK, enough of the back story...

    I bought a replacement main board and hooked it up.. It worked... Sorta...

    The display only covers the left 2/3rds of the screen...

    It occurred to me that the board I bought might not be the exact replacement. Like putting a Main Board from a 40" into a 50" TV.. You would get a size disparity..

    But, the boards are virtually identical.. The only difference is the top set of numbers/letters on the pictured labels..

    Other than that, the boards are numerically and component/connector placement identical..

    Now to throw another idea out there, it's POSSIBLE that the TV had this problem PRIOR to my connector-challenged issue...

    So, my question is two-fold..

    1- is there some difference in the main boards that would explain the lack of full screen

    or

    B- if there isn't any difference in the main boards, what could cause the display size issue??

    I realize that exact model number of the display and a pic of the display while on would help. I can get those tomorrow when I go to my shop...

    Any hints or tips would be greatly appreciated...

    I don't know but a search of the PCB number lead me to this.



    Failure to configure the SSB can result in no picture, the picture being severely
    shifted on the screen, and some features not functioning.

    part shows it used in 32,42,50" Tvs , both LCD & Plasma

        Incidentally, which number on the PCB did you use??

        Disregard

        Seems I had the information when I posted...

          Go in to settings menu. You will find an option there for screen
          Size. I only barely remember due to seeing this a long time ago

            Try swapping the eeprom from the old board to the new board if there is no option available in the service menu. Identical components doesn't necessarily mean identical boards.

              That did it..

              The tag on the back did not have a SCREEN DIVERSITY CODE on it, but a search of the BadCaps forum produced one.. 085

              So, I am good to go.. Many thanx to all...
