So my NAOMI just stopped working. Not sure what is wrong. Here are the symptoms:
 Upon power up, NAOMI fans turn on, then shut down after 5 seconds
 Machine is turned off
 Power is turned on immediately, no fan activity
 NAOMI is allowed to rest for a period of time, then is powered on. Fans turn on again, but shut down after 5 minutes
I have a Capcom I/O board. Also, I pulled the JAMMA connector off the I/O board and plugged another PCB, no luck either. I am seeing the LED on the board light up (MK1), then it shuts down. Is this a power supply issue? Can the power supply be fixed?
Or given that I have the Capcom I/O board, I don’t have a GDROM, can I just use an arcade switching power supply to get life to my NAOMI?
