I was just testing out a Gal Panic 2 (II?) PCB, and it will not boot up.

It starts its test cycle, and the test says ...

CHECK 0 ..L1
CHECK 1

... and then the board resets and does it again.

I am a complete n00b as far as fixing boards goes.

Any suggestions?
 
Carefully pull the ROMs, clean the legs and reseat them. It is probably best to pull them, clean and reseat them one at a time so you don't get them out of order.

If you have an EPROM burner, you might want to dump the ROMs and check against a known good set (MAME).

I am not sure which are the ROMs. My search for a schematic turned up an operation manual, but it really only had DIP switch settings and not much more.

Is there any information to help me get started?
 
The ROMS should be the six 32 pin chips scattered 2x2 on the board. On my GP2 board they are the ones with the labels on them. I am not sure if the larger socketed chips markd Kaneko. It probably wouldn't hurt to pull those one at a time and resocket them just to make sure they are making a good connection.
