Hey all. Any thoughts/advice appreciate with this issue!
I recently bought a 1981 Flash Gordon. Super happy. When I received it everything worked for the most part (I haven't gone through testing every inch yet). Yesterday, I needed to move the game into my basement. In order to do so, I had to chop the head off, bring it downstairs, and then wheel the cab down separately. Thankfully, I was able to move everything without causing any physical damage. I reassembled it today (I made sure to properly mark everything I disconnected, and took pictures before to compare to after) As far as I can tell, I put everything back together exactly as it was when I disassembled. Game boots fine, plays exactly as it did pre-disassembly, BUT two sets of lights don't work. 1) The "Flash Gordon" lights on the head (all the other board lights light properly) 2) none of the main playfield lights (like where the dial numbers are, or the top playfield lights. However, all of the side and ally lights seem to work (see pictures below). So I don't get it. I checked the fuses, none seem popped and are all seated. I triple checked that I put everything together correctly, so I can't figure it out. Please, and advice, suggestions, etc. is greatly appreciated. Thanks everyone!

Thank you for the suggestion. I need to order a 20a fuse to test it. Any idea why the fuse would have blown just from disassembling and reassembling? Think I put something together wrong?

Yup. Absolutely made sure of that. I’ll swing by Home Depot tomorrow, they have bussman AGC 20’s in stock in a 5 pack for 2 bucks.

No, I just pulled them out and looked to see if the filament was intact. They all appeared to be. I'll pull out my multimeter in a bit and check them. I'll also double check the three connectors to make sure I didn't screw up there.

Game is nice, I'm happy with it, but it needs some TLC. It was routed until I got it, so it needs a good deep cleaning, fixing up some problem spots (some of the lights don't work, not everything was converted to LED, one of the targets doesn't seem to be operating correctly, a couple of the plastics need to be replaced, etc.) but when it's done it will be fantastic. This was THE game for me when I was a kid, I spent hundreds of hours playing it, so I have a lot of memories from this, it was nice to get one.

Ok something is shorting. I replaced the F1 fuse and as soon as it turned on it blew. Whats the best way to run down what's causing the fuse to blow? Thanks!

So I disconnected the two cables to the lamp driver. When you do that and boot it doesn’t pop the fuse. But if you connect either of the cables it blows the fuse. I reconnected the ground cable just to make sure it wasn’t causing an issue. Anyone have any tips?

Ok so it’s something on the playfield is what you’re saying? I’ll look over every inch. Is there any tool that helps (like using a multimeter?) or do you just inspect for anything touching that shouldn’t be?

Ok, so this is REALLY weird. I went through each bulb on the Playfield. Eventually I got to a bulb that I removed when I moved the machine. When I touched my DMM to it, it didn't register. So I put in a new 44 bulb. When I touched the DMM to it, it sounded. Ok, figured maybe that was causing an issue. Put a new 20A fuse in, fired it up... and the lights came back on. Why would a missing bulb be causing a fuse to blow? Is this a sign of something else being wrong? Thanks everyone for all your help.

Thanks, I wrapped it down to make sure it doesn't touch anything.

Now... time to figure out why half my GI lights in my WWFRR backbox don't work. LOL
