When do your backglass fireworks light up? Just got the machine and trying to figure out if there's a problem or a score/combo I'm just not hitting.
 
I'm not sure how different sys9 is vs sys11 when it comes to the lighting, but if it's anything like my Cyclone, I had a drive transistor out keeping some of my backbox lighting from coming on.
Do you have any lights on the playfield that don't work via self test? Because of the matrix you usually see at least one other set of lights inop if that is the case...

**edit: here is a thread that may help, also try the quick and dirty test for your transistors as referenced on pinrepair **/edit

I can help you Dan....The fireworks are flashers and each flasher is by the 1-4 player display. Fireworks go off when you first start the game, when the game ends and when you get the 1 million shot. I had a problem with mine and the culprit was some transistors on the mpu board.

I also saw your coinbox ad. I don't know about anybody else but I think they were just trays almost like the ones used for painting. So there might be no boxes....
 
Thanks guys for confirming that they're all supposed to flash. I checked mine again tonight, the top left and right fireworks are working, the bottom left and right never flash.

I confirmed this with a few video searches on Youtube, too. When the other guys' fireworks are going off, all four flash.

Will have to see if that's a board issue. I checked the lamps and sockets, all seem good, haven't dug in with my meter yet.

I checked IPDB pictures regarding the coin box, it looks like it had one....? I asked the seller (Pinball Plus out of MN) and they said they'd keep an eye out but the boxes are getting hard to find.
