I bought my first machine, a Dungeons & Dragons: Shadow over Mystara, yesterday. The game seemed to work perfectly fine when I bought it. I just got it home and plugged it in and I heard a pop or boom noise. Now the game wont turn on at all. Any help would be very appreciated.
 
Did you open the back up and check it out? could of had something in there like a screw short something out. Check all your fueses, im guessing the pop was one blowing. Go from there.
 
Sorry for the dumb question, but where and how do I check the fuses? I have no experience in anything electrical.
 
i was new once too

We all were new to collecting at one point.. so I'll give you one very important piece of information:


Google.

ask google how to check a fuse :)
ask google how to pretty much do anything at this point.

Once your done with the basic research.. come on back and ask lots of questions.. there also is a search function in this forum.
 
Your fuses will be on the bottom inside the cabinet. Take the back door off and have a look around. You can post pictures of the inside of your cabinet so we can help better also.
 
Yes its common to have a washer or screw left in the cabinet and then if not caught before it's transported, the washer or screw can lodge itself in the fuse block and blow a fuse when powered on next time.

Lets hope it's just a blown fuse you can easily remove and replace.
 
Wow!
Someone did a hack job on the wiring........ :p

Yikes... you're not kidding.

The first thing I would do is exactly what I did with my first "fixer-upper" game. Order a brand new Jamma wire harness and an assortment of connectors and quick-disconnects and replace all the wiring in there. It would also be worth it to buy the parts to build a new power supply setup... or just pick up one of Bob Roberts' pre-built drop-in setups. You can find everything to fix the wiring and power by searching here and then at least you'll know that the wiring is right. I had pretty much no knowledge of what I was doing before I got into this hobby and there are so many resources online that you'll have that thing re-wired in no time. But to be totally honest, the wiring on that thing gives me a headache just to look at. :) And the dust makes me sad.
 
There also seems to be a lot of loose metal in there ie. screws, nuts, washers, and some sort of bracket. Chances are something got lodged somewhere it shouldn't be. I don't even think I seen a fuse in that jungle.
 
Thanks for all the help guys. Turns out it was the outlet I was using. The game turns on now, but the image has vertical line distortion and there is no sound. I turned the volume all the way up and still no sound.

He's not quite advanced enough to do this yet.

Lets see some pictures of you screen. As far as the sound. Make sure your speaker wires are connected. My guess is that the wiring is hacked (from a 4 player konami cab perhaps?) and that the wires came loose in transit. Follow the wires from your speaker back to the wire harness connected to the pcb.

I have now uploaded pictures of the screen. I believe you are right about one of the speaker wires. It looks like it broke during transport. The other speaker seems to be intact though, so I don't know why that one doesn't play any sounds. As for the cab, I believe it was a 4 player X-men.

No, I hear you. But the best way to learn is to dive right in, right? Seriously, between searches on this forum and reading Bob Roberts' how-to's I went from knowing nothing about electronics, soldering, pcb's, etc etc etc to being able to do pretty much anything I would need to do with games. Throwing in a drop-in power setup and a Jamma harness would be about as easy as it comes in arcade world with the step-by-step walkthroughs and illustrated diagrams.

But yes, if the end goal is to get this game going asap then this might be a bit much. My little bit of OCD just couldn't handle knowing the wiring was that insane. It would drive me nuts. :)
 
Good news is thats not a monitor issue, bad news is thats all i know. I dont know anything about your game. Someone will though.

The Konami cabinets wire wired for true stereo via a seperate 4-pin connector to the pcb which standard Jamma doesn't support. in order to use most jamma pcbs in the cab without damage then one speaker would have to be disabled or re-wired. I'm betting that one speaker was just disconnected if the speaker was wired up at all. Did the sound work at all before you moved it?

Also, the image is a pcb problem but its probably minor. All you should have to do is remove the pcb, it has the blue top board and the black bottom board, then pull them apart and re-seat them nice and tight. That SHOULD fix your issue. If not, let us know.

True but I'd say let him see how it all works for a bit first. Fixing hacked wiring can help you learn quite a bit as well. I, to this day, have never rewired a cab completely and been 100% happy with my work.

I'm pretty sure it did, but I got it from an auction, so there was a lot of background noise. I'm almost positive there was sound though.

Thanks, I'll try this first thing in the morning and will post my results.
 
first thing i'd do is pull off the edge connector (the wiring connector that plugs into the main board,) and put it back on. make sure it's nice and tight. that may solve your video issue without even having to take the CPS2 A and B boards apart. of course, make sure to do this while the game is turned OFF.
 
I removed board A from board B and put them back together. Now this is all I see.

edit: I did the same thing again to see if that would fix it, but now I just see the second image.

Get a bottle of denatured and alcohol a toothbrush. Dip the head of the brush in the alcohol and scrub both the connectors on the top and bottom boards. Then, while they are still wet, put the boards firmly back together. Pull them apart and put together again about three our for more times and then try powering the game back up.

If it is dirty contacts, this process should take care of it. From what you have described it seems like the most logical cause.

Good luck.
