Always worth mentioning, have you connected it correctly?

Hello,
Yes I’m using a jamma adapter. And I double checked that as well…

You probably have a Tantalum cap that is shorted. Common issue. An ESR meter can be used as a high frequency milliohmmeter to find the tantalum cap with the lowest resistance across its leads.
If you have a multimeter you can check reisistance (with the power off) of the disconnected PCB to see if it's the +5, +12, or -5v that is shorted to ground.
