Raiden fighters jet pcb blurry crap onscreen on start up

Post by Hrvat9 »

I just got this Raiden fighters jet pcb that no mater what, on start up has this screen.

Only after I press the sw1 button on the pcb does the game boot up normally. Anyone have this with their pcb?

At U015. Can anyone check if that’s supposed to be like that? That definitely looks like it was fiddled with
One leg lifted and the two traces joined with a blob of solder

Don't know for sure what it's supposed to be, but I've bought it with this 'mod' already done.
And it was working fine at the time.

Do you have a supergun or another cab to verify the issue?

A few of my pcb display scrambled graphics on startup. I believe it’s to speed up the ram checksum.

If you have hit a button to make it go away that does not seem normal.

If it doesn’t effect starting and playing a game. I would ignore it.
