Hey all,
I recently got a Kaneko Gal’s Panic (EXPRO-02) board that I’m trying to diagnose the issue with. As the title suggests, I’ve repeatedly gotten GRAM Error, address 0052000[X][X] (the two lower bits swap every so often). I replaced the U52 RAM chip (41464) and tested it with known good ones,but there was no change. I also tried removing U27 and U41 (both causing BG Error). What should my next steps be? I have a second board I’ve been pulling various chips from to test stuff. The photo I attached is of the board that I am trying to fix but I will be glad to add one of the second board if it would be of any use.
