Can someone identify a possible solution? Fuses f10 and f11 blow at power on, though maybe rectifier but switch them out from working pin same issue.

Saying aux power supply for sound board, im not able to bootup. Unhooked them to try to get startup but still nothing all dead but a few lights on pf. Now im getting this on dmd, replaced u8 no luck.

looking for ver.5 game romset to update the my pin to see if that helps. Please let me know you have one you can email me. Thanks

found romset on vpforums, has
arom1 512kb
arom2 256kb
drom 32kb
dsprom 512kb
gprom 64kb
yprom 32kb
Can someone help explain each rom, the two i think audio? drom-Display? dsprom? gprom-Game Rom? yprom?

64kb seem low for game prom?
Original shows a M27c512 prom but a copy of it shows 64kb, would think the newer version be larger, 64kb to small for a 512kb eprom right?

Please assist as i am working on it atm late night,
