Hi guys. Just connected a working CPS3 in my new purchased astro city and I get this screen. Does anyone know what can be wrong? I'm running 3rd strike.

CPS3 can be finicky, I'd test the new cab with a different game first if you have one. Best to isolate the issue rather than debug a new cab and CPS3 at the same time.
 
Hi guys. The board is working, I tested it a few months ago on a blast city before. Now I checked the voltage from the Jamma, and the voltage was 4.62. I changed it to 4.96. Works fine now. First time I'm dealing with this arcade stuff, but for those that don't know, be as close to 5 volt when playing on larger PCBs like the CPS3. I also learned that you should always check voltage before you connect a PCB, this is to prevent it from being too high and damaging the hardware. Maybe most of the people here know this, but I had no clue at all, so I was lucky that the voltage was low. Also what was interesting was that when connecting the voltage meter without a pcb, the voltage will be higher, connected to a PCB voltage will decrease.
