Strikers 1999 PCB issue

twalden · Mar 4, 2010

I have a Strikers 1999 PCB (Psikyo SH2 hardware). When I let the board sit for a few months without powering it on, it takes 2 or 3 power cycles to get it to power up. As long as I turn it on every few days, it seems to be ok. Possible bad caps or something else?

You'll find that at least 9 out of 10 capacitors on game boards are used for sound. As they are supplied with a regulated DC supply, no caps are needed for power.

Does the board use a battery by any chance? Thats about the only thing I can think of.

+1. Corrupt NVRAM will cause all kinds of odd problems.

Thanks for the help. There's no battery, but I'll try replacing the NVRAM if it's an easy chip to source.

Look to see if there's a PIC chip on there for security. If so, reseat it and resolder the crystal connected to it.
