So sick of looking at my totally restored Hulk just sitting there with nobody to play with him. Game will not boot, but GI and BB light up. Loud humming through the speaker. No displays, although they do flicker when you turn the game off momentarily. The guy I got it from rewired some of the bottom of the PF, but for the most part it looks OK. There are a few wires not connected (looks like they belong on one of the bulb sockets?). Photo below. The fuses all test good, and MPU appears to be getting the proper voltage. Also took a pic of the transformer board. Don't see any other "loose" wires.

Is there something I'm missing? Any help would be greatly appreciated.

By the way, if anybody has a manual or schematics they can PDF to me, I would appreciate it. First game in a while I haven't had a manual for, and what a pain in the ass to attempt to work on a game without one.

You'll need both the game specific manual and the system 1 manual

You dont really need the above 2 things, rather just read this article...

Thanks for the links. I have Clay's manual, just downloaded the update. Was just looking for a simple direction to be pointed in, before I dive in from the beginning.

Going to start tackling this tonight, so if anybody has any other shortcuts / suggestions before I dive into Clay's 400 page System 1 repair manual, I'd appreciate it.

It's a basic step but have you tried reseating the connectors? Any difference in boot up when doing so?

I've got a similar problem on my Hulk, but displays light up and cycles through high score. Each time I reseat the connectors, something different happens (no displays, tilt stuck, etc). I'm thinking I'm going to repin them and if that doesn't work, upgrade to a Pascal/Flippp board.

I did reseat them right out of the gate....I always force myself to try the most simple "repairs" first. A few of the connectors seem to be a little loose and scratchy, and might not be getting good contact. No idea why Gottlieb used this type of connector. I don't which are worse...System 1 or System 80 games. They've always seemed equally bad to me by design, and just the amount of issues. A shame with so many great titles.

Back to the task, I do have to check the voltage at the bridge rectifiers, and it looks like I'm ordering and repinning all connectors. I try to do that on every Sys 1 game I've had, but was trying to avoid it this time around. Looks like I won't be able to.

Did you see my pic in Post #1 above with the three wires? Can you take a pic of yours and post it so I can compare? They are under the left flipper mech, slightly to the left. I resoldered the green/white wire to the lamp socket after I took that pic (looked like someone had just cut it with a little piece still on the socket), but there are still the two black/white wires dangling there. Not sure if they are dead, not used, etc. Seems odd. Wanted to know if those wires were going anywhere on your game.

Did you use a pink rubber eraser on the edge connector contacts? That removes the layer of grime/tarnish that tends to build up.

I didn't, but I'll do it while I'm in there. Thanks for the input.

colsond3 Forgot to upload these for you the other day. I believe those are your black and white wires in question.

Awesome...thanks. At least now I can resolder those and move on.
