Dead screen CPS3

[fjaza]

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.

Clean contacts of cart and check voltage on battery. Could be dead cart. Did this board work before?

Does it output any sound or does the CD Rom drive spin?

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.
