I basically got my blast almost a year ago. It's been working fine until today. I hadn't test the voltages on my boards recently, but last time I did (who knows maybe a few months ago) everything was in a decent range (+5, +12 were both very close to where they should have been)
Anyways, get a new board today, and start by going through the test mode to change the settings, I'm changing a few dip switches, and then the test screen freezes..I turn it off, back on, and only the initial ram test info shows up (all as good)
I test the voltages on my board and they are at 6.9V and maybe 15V or so...I lower the voltages to about as low as the dial will take them to 5.69 and 13.XX something..Anyways, the new board will now not turn on other than the ram test...Run another jamma board and it powers on, runs/plays fine, and the voltages show the same as before (5.69 etc)..
I guess my question is: Can power supplies just go bad out of nowhere? How often am I supposed to check the voltages on my boards? Did I most likely kill my new game board? How easy it to change a BC psu? Is the PSU most likely the problem?
