Well crap, I think something very bad might have just happened... I had pulled the playfield out to adjust a few things, the left slingshot switch, the plastic guide at the top of Insanity Falls, and I added a couple rubber rings to the No Way Out VUK to try and eliminate roll back. Once I finished I turned the game back on, heard a very faint click (Which I initially assume was just a plastic settling, and maybe it was) but the game won't get past the test screen. GI does come on. It still makes the normal beep sound but that's it, after that it's completely unresponsive. Test buttons don't do anything. Big Foot's head never spins like it normally does when starting up. I tried restarting the machine a couple times, no change. Worst part is, unless I'm now just being paranoid and this is totally normal and I just never noticed before, I think I was able to smell something electronic. Not smoky, just seems to be a stronger than usual electronics smell.
I checked all the fuses. None seem to be blown (I checked with a multimeter while they were installed) however a few are incorrect according to the manual. I'd been meaning to check them all to make sure they were correct but I was having too much fun playing and kept putting it off...
The incorrect fuses are:
F113 - Has a 5A fast blow, manual says it should be slow blow
F114 - Looks like an ordinary slow blow fuse, however manual says it should be normal blow. I'm not really sure how to tell them apart though so it could be correct EDIT: Just did some research and found that normal blow means fast blow, so this is definitely wrong.
F115 - Manual says it needs a 3/4A slow blow, but the fuse that's currently there doesn't seem to specify what it is. Labels on it are 32 VOLTS and BUSS AGC 5
F901: Has a 3A fast blow, should be slow blow
F902: Has a 2 1/2A slow blow, should be 3A
F904: Has a 5A slow blow, should be 3A
I'm not really sure what to do next. I'll swap out the incorrect fuses with the correct ones although I might not have all of the correct ones on hand. Besides that though I'm kind of afraid to try turning it on again and potentially causing more damage... Assuming something's been seriously damaged already. Hoping it's just a loose cable or something.
