  • Board issues

    Today I picked up the following boards
    TMNT
    Simpsons
    Growl
    MIA

    None of these boards work 100% as I think the cab they were in was running at 13.5 volts which may be the source of the problem

    THE TMNT has corrupt back ground graphics at the start but plays and looks okay during the game

    The simpsons has good back ground graphics but all character or dynamic images are corrupt

    Growl does the same thing

    MIA does not even get past the first test screen.

    Any ideas the only one I really want to fix a run at 100% is the simpsons the rest I will sell if there is not an easy fix.

    TMNT and Simpsons bad mask roms or pins have lifted on customs or customs foobah. Will not be rams as it would not get past the ram test at the start.
    Unfortunately despite what some people think board repairs are not always easy fixes like reseating roms.
    I just finnished fixing 2 TMNT and those Mask roms are a common problem.

        Mask roms are the big 4 or 8 meg roms either 40 or 42 pin. Customs are the 4 surface mounted chips can't miss them. The legs can lift up and need to be resoldered down. If its the Mask roms they will have to be removed and replaced.
