    Tried to upgrade battery to NVRAM chip on my Sega Space Jam and when I put chip in game booted up to the display screen and then picture after that on DMD. Had sound and all GI lights on. Took chip out and put back original RAM chip plus I bought a new on from Marco. Now only have GI lights. Reflowed I/O board pin connectors and no help.

    All fuses ok. On I/O board 20 and 50 volt red lights not on. On MPU L200 red light is not on and on I/O board L204 red light keeps blinking.Reset did nothing. Game worked prior.

    A couple months ago same indicator red lights out the 20 and 50 volt. I moved the harness towards the top and it was fine. Reflowed MPU also after chip swap did not work.

    Here is video of the board after I turn it on.
