I'm currently in the process of getting my first owned (and all time favorite) pin BSD up and running. After fixing an error with the board I'm getting this error from the game audits.
TOP LEFT POPPER OPTO SWITCH 56

Not really able to find this exactly in the manual, but it seems to be the sensor on the Renfeld hole even though top left make me think the mystery/mist hole. Any suggestions?

Thanks gonna work on it later and will report back.

Months later I'm finally back and I got my BSD up and running...other than one last error "magnet unload error." Running the test in the menu shoots several balls down the trough and runs the magnet back and forth. I am able to see both optos with my cell phone camera on either side. I'm noticing its not kicking a ball into either mist hole during the test, and there isn't one sitting in there by default. Could my machine be down a ball or does it sound like opto alignment/board issues?

I'll take a look at it and see. Should there be a ball in the left waiting on a mist multiball at game start? I don't have one in there.

Looks like neither side has a ball in it at game start. Game is going straight to mist multi when the back hole is shot when mist is lit.

So the plot thickens. I pulled up the playfield to get pics of the board and there was an old opto board in the bottom of the cabinet in a bag. Its totally warped and no doubt bad and was replaced. I attached a picture of it for reference. The one installed is what looks like a brand new one from home pin.com. It looks to be in pretty good shape as least as far as a novice can tell.

Some history on this table . Mid 90s my parents were in the arcade industry this was one of our favorite tables but when the industry went kaput they had to sell all their stuff and dad and mom got more traditional jobs. A few years back dad got in touch with an old industry buddy who was still keeping on in the amusement world and he started helping him some on the side. About 6 months ago he called me and said a guy who used to help him had died and his widow wanted to sell some game stuff he had and dad was the only one she knew to call. Sure enough when he walked in there sat our very same BSD. They were going to flip all the stuff this lady had but I told him I'd buy the BSD whatever it took and she offered me a great price since it didn't work any more. I paid the lady and the table went to my dad's associate for repair. When he got it the rubbers were rotted , the right flipper wasn't going, plunger didn't work, and it was showing up two opto errors . He took ill and wasn't able to work on it beyond fixing the plunger/flipper/rubbers and it sat there for 4 to 5 months till he was able to work on it again. The last thing were two opto errors(probably related to this) and the magnet unload error. The optos were replaced and it stopped showing an error on those, but now it still shows magnet unload error. He pretty much gave up on fixing it so we decided to get it back since you can play it just the killer feature doesn't work.

Thanks for the detailed info. I ran a switch test with everything back in to see and The Ball on Magnet T3 82 Opto is flashing between open and closed rapidly. If I put my hand in font of the beam it stops.

I'll get to testing over the next few days and report back when I can thanks again for the advice.

Thanks I will try. I've been fixing a few more smaller issues our tech didn't fix/finish when he had it. The Coffin ramp torch lights weren't out like I thought but just left hanging loose not screwed in under the playfield, dead left outlane switch and a few other things. Once I get the easy stuff I'm gonna start on this mist issue.

Thanks all for the help everyone. Turns out the replacement board was bad. Got it replaced and now 99% of everything is working save a few lights.

Is BSD supposed to have a pole or something to hold the playfield up ? Mine doesn't stay upright unless you hold it , and it makes it very difficult to work on as you can imagine! Here's a shot of what it looks like now.

It came to me this way. I knew something was off with it since the family business used to work on them in the 90s but its my first time owning one.

This sounds extremely useful I'll read up. Thanks.

Hey all. I'm going to be doing an interview with Paul Heitsch, who composed this game, (tentatively) next week on my youtube channel. If you guys have any questions about his work on BSD or other pinballs feel free to drop them here or PM me and I'll do my best to ask them. I'm definitely going to be asking a few questions about this game since its my favorite pin.

I recently turned on the attract mode sound and starting leave the game on on days I work from home. It goes through all the standard callouts from the game but after about 3 hours or so I heard one I'd never heard before. It was something like "we'll meet again my mortal friend" anyone ever heard this call out before? I haven't been able to get it to make this sound again since.

I'm doing some testing on it for science. It seems when you turn on the game and set it to attract mode sounds often you get the same callouts in sequence assuming you don't mess with it. You have to wait about 10 minutes between callouts and to hear the unused one takes about 3 hours. Working on a list to see if there's any more "hidden" ones.

I made a list of the first 20 or so and will see if it's the same tomorrow on start up.

Just installed pinball bulb's LED lighting kit and it looks fantastic, but I've noticed one of the coffin lights stays on dimly during gameplay. Looks fine when a ball is locked or in attract mode, but just during game play its partially lit as below. I checked the voltages on the bulbs. The one that's staying on is 3.1 and the one that is behaving normally is 2.8. Any suggestions? Works fine when I put old style bulbs back in it. When you view it through the phone camera you can see its flashing ever so slightly in tandem with the skill shot face light on the back.

Cycled out several bulbs and all LEDs do the same thing. All non ghosting.

My right flipper spring snapped during play the other night so I decided to do a flipper rebuild(first time doing one). After installing the right flipper starts out fine but starts to stick higher and higher the more you flip it as in the image below. If you cut the power with it up it stays stuck up there so definitely think I have something too tight or not tight enough. Any suggestions?

The rebuild kit came with a spacer tool that I used. Per the manual I've replaced all washers, but I'm double checking now. Here it is as it sits too high atm.

If that nut isn't tight enough I'm gonna have to hit the gym that thing is on there.

Sorry for double post.

I went to the tool box and got something a little stronger and a better angle. The other flipper was clearly tighter than I had it so I tightened it to match and now no more sticking. You guys are the best. Love the powerful pop it has after the rebuild looking forward to starting the other.

Really digging those purple ones. I got the black ones before I put in LEDs and I think the purples might suit it better.

Also finished the other flipper tonight and hit grand champion. I'm now a believer in flipper rebuilds. Plays like a whole other game from what I was used to.
