I just got an IREM Hook pcb. It looks in great condition but I get nothing when I try to power up the board in my two cabinets. The screen flashes then goes to a lit background (no color) with no audio. None of my cabinet buttons seem to do anything.

The board itself is very clean. It looks like its a two board set with the Hook roms on the bottom board. I don't see any damage and really don't have much experience troubleshooting pcbs. I could remove and reseat the roms or take the two boards apart and reseed them.

I'll try to get some pictures up soon. Any ideas where I can start with this? I do not have a manual and there are several sets of dips. I'm trying the board in a Killer Instinct and Gauntlet Legends cab.

Ideas?

I found this link to partial dip settings, I am unsure if these are correct:

The board has 3 dips SW1 - SW3, all with 8 dips.

When I got this board it was set as:

SW1: 4 and 7 ON
SW2: 3 ON
SW3: all OFF

I tried resetting it to:

SW1: 2, 6, 7 ON
SW2: 2, 5-8 ON
SW3: all OFF

No change. I also tried chaning SW1 dip 8 to ON which should be test mode. No change there either.
 
At the request of a member I separated the boards and checked the pins and solder points. Everything looked ok. I put it back together and tested it and it still gives the same results.
