I have somewhat of a similar issue with mine. All the boards have just been gone through and nvram installed. I can play a game with no issues but I cannot get into diagnostics. I resoldered one wire that had fallen off from the middle lug of the advance switch to the middle lug of the manual/auto up switch. But even after that, the advance switch does nothing. I can switch to auto up and the displays go blank. When I switch it back to manual I get the #1 through all the displays. When I switch back to auto up and then back to manual, #2 is displayed and so on right through #9. The CPU has new Green flipper roms and game rom installed. I want to get into diagnostics since I have no background sound, just game sounds.

Not sure if you are asking PinBobF or epeabs ? Thats a good point, I have not actually checked my coin door switches with a meter. But that brings up another question for me. Does anyone have a few pictures from different angles of the wiring at the switches themselves? You never know on a "new to me" machine what is wired correctly or not.

I found my problem on the coin door switches. The IJ4 connector on the CPU had all three wires off one spot. Locations 1, 2 and 3 were being used and #4 was open, yet #1 is the key. Moved all three wires over one spot to locations 2, 3 and 4, and the coin door switches work properly. But even setting the background sound to on, it is still not there. Do I need a new sound ROM?

My other interesting issue is that when pressing the right flipper, I am scoring 10 points (which is the amount for the slingshots). I have opened up the slingshot contacts and it is still occurring. The left flipper also scores some points, maybe 30 or 40. I have also tried banging on the playfield but not really getting anything to score.

Thank you @slochar. I think that was part of the problem, I had looked at the wrong page for adjusting with the green roms. Setting #31 (new number) to 01 should give me the background sound throughout the game, but it isn't still.

Not sure if it helps, but here is a picture of the power supply in my Flash.

I am looking for this gate coming out of the shooter lane. Does anyone have one in excellent condition or new? Where could I purchase one new? I've searched via part number, but I'm not coming up with it anywhere as a new/repro item.

Sorry, my bad for not writing correctly. I'm looking for the bracket that holds the gate.

I am wrapping up a playfield swap on Flash, with all new bulb sockets, etc. The boards were professionally gone through prior to the swap and the game was playing fine. I have re-pinned all the connectors in the backbox (I didn't replace header pins) and I still have five switches that are not registering. The three right side star rollovers, the spinner, and the upper right standup target behind the rubber. I have continuity from the correct pins in the backbox connectors to each individual switch. All switches are in column 3, but the three jet bumpers work fine. What am I missing?

I just went into switch test. I removed 2J2 and 2J3 connectors and jumped the corresponding pins for the switches in question. They all register when jumping the pins. I then plugged the connectors back in and activated each switch. The five in question are not registering in switch test.

Not exactly the assistance I was hoping for.

Haha, gotcha. Didn't think you were actually trying to be snarky. I have continuity from connectors to the switches. I am pulling apart the harness in that area currently. Trying to see if something is not connected properly.

An update to my dilemma.... There was one wire in the daisy chain that had broken loose, so that has been resoldered. But that didn't fix the issue. Found out that the 15 pin white/white connector from playfield to backbox was "bad". I repinned that connector (what a pain in the ass those are) and the five switches now all work. I have to check a couple of the pins since my ball kickout is now intermittent, but I think I am heading in the right direction. Thank you for the suggestions.

Next thing to troubleshoot. I've got several "phantom" inserts lit upon crediting a game. The 1, 2, 5, 2X, and right outane inserts are on without playing the first ball. Diodes are correct and new. I dont see any crossed wires. Thoughts?

I believe so. I will confirm. All bulbs do work in test.

Yes. LEDs.

I will try tomorrow. Still not home from a small tournament.

Yes

Replacing the problematic bulbs with incandescent fixed most of them. A couple are still lightly ghosting and one is still fairly bright.
