PGM Motherboard Issue...

[Sparkoids]

It isn't the games - they all run OK in another console. I have cleaned the contacts and removed the daughterboard to ensure the connectors are completely cleaned with IPA.

All hardware tests without a cartridge pass perfectly so I am completely stumped. The carts go from booting to black or dimmed frozen screen, some don't boot at all and Bee Storm 2 always gets to this screen.

I swapped connector daughterboards but then neither console worked so swapped them back and went back to this.

Any ideas please?

I presume a Revision 5. It says IGS PCB NO-0133-5 on it and the silkscreen in the middle of the pcb says K87B4003A.

I'd be surprised if there is NOT any Battery / track damage to this unit.

It's actually OK on that front. I am trying to get a Rev 14 from China on Aliexpress but no luck at the moment. That's a great PGM site you run btw. The board was working OK until recently

If you want a REV 14. I can sell you one. I normally sell them as a "Pre-Modded" motherboard. But i can just sell you a stock unit instead.
