mv-1fz player 2 select stuck

[Robertguy09]

I have a Neo Geo mv-1fz board where the player 2 select is stuck in the test menu.

Does anyone have any suggestions on where to start troubleshooting this issue?

I have a couple of parts board for extra parts if needed.

Check the CRE401 / CR-10-A related to your input. Sometimes a cap(s) inside fail short and tie the related input(s) to ground permanently, making it constantly on.
From your input you should measure 1k to +5v, 200-300R to NEO-C1 corresponding input pin, and more than 1k (and rising typically) to ground.
Worst case is NEO-C1 has that input shorted internally

Bummer... Looks like the CRE401 is fine.

I'll try swapping the NEO-C1 and see if that fixes it
