Hello!

I've been struggling with my creature for about two weeks now and I am totally stumped. Since I have got the machine it has booted rather slow and now doesn't want to boot at all. If it does get running it runs and plays perfectly. I swapped out the power driver board for a board I knew worked, test point voltage remained about the same.

TP1 (12vu) = 14v
TP2 (5v) = 4.9-5v
TP3 (12vr) = 11.8v
TP4 (zc) = .4v
TP6 (50v) = 70v
TP7 (20v) = 20.6v
TP8 (18v) = 14.2-17

These were almost exactly the same between two boards, fuse F113 has blown twice in about 20 boot ups causing the 5v to not work at all, after replacing that it booted, but still slowly.

After this I swapped the CPU board with a brand new ROM and it got even weirder. On the old board it just power cycles with the top and bottom LED being lit on the CPU. With the new board the top and bottom LED light and the flashers on the machine go crazy, I think I even heard a solenoid fire. There is no power cycle or indication it wants to boot at all. After putting the old board back in it just power cycles over and over with no sign of booting.

Here are some pictures of the boards:

Thanks for any help you can offer!

Made sure everything was re-seated including the ribbon cables, the 5v on the power board is reading normally and the components are functioning. Swapped the CPU board again, the flashers still go crazy when I turn it on with the new board. Old board just power cycles.

I went through and made sure all pin connectors were in the right spot and swapped boards again. When it boots up the GI and flashers pulse every few seconds and it makes clicking noises. Legit scared to turn it on. I'm at a total loss because I have tried 2 different power driver boards and two CPU boards with 2 different roms. In addition to a combo of each.

I'm in Bellingham, WA, to my knowledge it is not a reimport machine (how would I check this?) and the machine has no mods.

It says 120v 8 amps on the back sticker. It was booting slow/cycling when I got it two weeks ago which led to all the things I have tried so far. Thanks a lot for your help!

I was not, I purchased it online. I was able to get it to boot when I first got it, though it was slow. I have put in two 5+ hour play sessions while it was booted and there was no issue while it was running. It won't boot now but when it did the machine ran great and there were no issues with the way the machine ran during uptime.

I reseated the ribbon connectors 3x and with the rottendog board it was still going crazy. To double check I put back in the board it came with. Works perfectly! I was able to boot it first cycle multiple times, I will check again in the morning to make sure it is ok. If so I am marking this thread as solved, thanks again for your help and a point into the obvious direction. Thanks again for the help, two weeks of pulling out my hair for the obvious.

Can confirm that it was not a slam tilt and the machine is booting up right away now. Thank you for the help and the lesson in loose connections. Marking this thread as solved
