Just got mine this past weekend, it's my first pin. Love it so far.

Newb here, having a weird problem with my gun. When I start it up, it usually plays fine for a few games, but then the gun won’t stop rotating back and forth and the game won’t use it anymore. The weird part is, other aspects of the game change too after the malfunction- it auto plunges, the ball save gets very generous, and if you start any of the hurry ups the timer doesn’t count down. Disabling the gun in the settings makes the other issues stop. After the malfunction there’s a credit dot and the test message says “gun broken.” Before the malfunction there’s no credit dot.

Another time after the malfunction, the test message said to check switches 44 (gun chamber), 45 (gun popper), 76 (gun position), and 77 (gun lockup). When I run a test on each individual switch, 45 is closed and displays an (A), while the other three are open. I'm not sure what any of that means. There is also a gun test, but that looks like it's just testing whether the gun will move and rotate properly, which it does.

Any suggestions- especially bearing in mind that I know almost nothing about pinball repair, tools, etc. I'm trying to learn as much as I can and have learned quite a bit in the past couple of weeks, but am still getting started. So, idiot-proof explanations would be appreciated. Thanks!

Thanks. In terms of looking stuff up first, I always do- it's only fair to try to answer your own questions first before you ask other people to spend time helping you. But, I'm at such a low level with this stuff that I can't really interpret or use a lot of the information that's out there yet. For instance, my first issue was a broken flipper. I watched/read several tutorials, but they weren't that useful since the flippers in the tutorials weren't laid out like mine, or they skipped over the really basic stuff that I need, etc. Instead, it took hours and hours, and many people on here patiently answering my dumb questions. But I got it in the end, rebuilt all my flippers, and I have a decent understanding of the mechanics of flippers now. By the same token, if I had a ramp with a broken switch or something I'm sure there are plenty of resources out there, but I have no idea where to even start looking with something like the gun. I've seen a lot of those posts you mentioned but I don't really know enough to implement what they're talking about. Anyways though that's good advice to look for frayed or loose wires near the gun, and that a lot of problems just require cleaning to resolve- I can start with that!

Got to Crime Wave and popped mine for a billy for the first time tonight. Awwww yeah.

Does anyone know how many DH samples/prototypes with the drop target in front of the warehouse were produced? I read 200 somewhere, but that seems low.

This happens on mine once in a while. If I give the cabinet a good shake it pops out, so I believe it's just the ball getting stuck rather than being trapped by the magnet. The ball search gets it out also, but I think that's just the effect of the magnet going on and off moving the ball around. I've replaced the balls recently, so it's not that.
