Just bought my first pin, seems to be in good nick with only a couple of issues. I'm a bit scared to start investigating as when the coin door is opened it doesn't acknowledge this on the display. Does this mean that it isn't disabling the high voltage circuitry? I don't really want to start fiddling unless I know I'm not gonna zap myself!

The other problems are:
- Crane magnet isn't picking up ball (machine doesn't have deadworld mod so this isn't too big a deal)
- 'D' drop target isn't popping up
- Machine isn't detecting ball entering subway
- Ball lock 3 & 'D' drop target lamps not lighting (I assume that's just the lamps that have gone, I've got some new ones on order)
- Volume down button isn't working

Just wondering if any of these are common problems? Once I know the high voltage is disabled then I'm much more happy to have a fiddle

Cheers for the quick reply all

D'oh, didn't think to try the flippers with the door open. Seems obvious now. I'll try that when I get back from work.

Didn't specify properly before. When I say the volume down button isn't working I mean the actual button isn't working, doesn't do anything in the menus either.

I checked the coin door open\close switch in switch test mode although it's reporting as working fine, it still lets me start a game with the coin door open and the flippers operate. I assume that means high voltage isn't being disabled when the coin doors opened for some reason?

Managed to fix the drop targets although the subway still isn't working. Does that just need removing from underneath and checking to make sure the opto is lined up?

I did the most nooby thing to do and forgot to grab the balls before flipping up the playfield. The strange thing is I seem to have lost two balls completely, I swear I've looked everywhere for them. One was in the cabinet, a couple were wedged behind the playfield and one had dropped into the sniper tower but I can't for the life of me find the other two. Is there anywhere obvious I'm forgetting to look? It's now kicking out two balls when a game is started, is this because there isn't enough balls loaded into the trough? It was working fine with six balls before.

And finally, still can't get the 'down' button to work even though the other three buttons work fine. I've attached pictures of everywhere I think it's connected, can anyone see any faults anywhere?

Game seems to eject the correct number of balls as long as an odd number isn't loaded into the trough, is this normal? I've got new balls on order so that should sort that problem out.

Just the subway opto and volume down button to sort out now

Was going to try the subway switch out in test mode but realised the flippers are still working even when the coin door is open. Doesn't this mean the high voltage circuits are still active? I'm still a bit paranoid about zapping myself

I've tested the coin door open/close switch in test mode and that's working fine there. Any ideas?

Fixed the subway switch. Found a problem with the trough opto now though. LED 4, 6 & 7 aren't transmitting (tested with my phone camera). Is the board knackered? Pinball Heaven sell one for £20 so thinking of just getting a replacement rather than attempting repair.

Still can't find where the problem with the volume down button is as well. Can anyone see any faults in the previous pics I posted of it?

I've ordered a new board. It had definitely been worked on before, tried reflowing solder on round the components which managed to get one of them working intermittently, but two are still dead.

Yeh I did get it from Arbroath, did it used to be yours?
