    Coils look ok usually the knocker coil shows burning however this one is clean

    Player one display should be replaced as it is showing some burned segments the credit match board shows a burned resistor this is likely related to player one problem.

    Very common to see burned resistors on the driver caused by a stuck cpu and allows higher current to run thru the lamp resistors

    An upgrade can be done to eliminate them.

    Replace all capacitors

    Batteries can be eliminated to avoid future corrosion problems.

    Replace the 40 pin connector between the cpu and driverboard.

    Replace all scanbe sockets the upper row of Roms ic 26,22,and,21 seated in the scanbe sockets could be eliminated using a combo rom at IC 14
