Hello Friends,

I have a Flash Gordon that I have slowly restored. I recently rebuilt all the drop target assemblies, flippers (3), replaced pop caps, lights, cleaned, waxed, took the whole thing apart, etc. It has a new Rottendog Power supply board, A new Strobe assembly board, and now new Alltek MPU and Soledoid boards. The only things that havent been replaced are the displays/board, and GI board.

I have points racking up slowly 1000 at a time when sitting idle once the game has started. It is annoying as hell after all the work I have done. It has do be a rollover or drop leaf since it happens when the playfield is sitting flat, but will sometimes stop when raised.

I have tried (several times now) to readjust every single leaf under the pf. Every rollover, every drop target, etc. I can get it to STOP by pushing down on certain rollovers, or holding a leaf (they work in a series, so it makes sense that making contact will stop it). I have even tried it while the machine is ON carefully, one at a time, just to look for the culprit.

Any ideas? This pin has been 18 months coming back to full playability, and I really want it ready for league play in a month.

Thanks for your help!

Hmm thanks. i went thru the tests today (and found out i had the sound effects on 0 and it hasa. lot more to it at 3!), and the stuck switch wqs showing 0. And then it stopped doing it haha. if it occurs again ill check behind the drop targets. thanks guys! Will post some pics soon of the project completed.

Still driving me nuts on this one The diagnostics tests show an occasional "01" flashing, which are the R/L outlane switches (top left and right rollver star loops). If I hold down any one of the leaf switches for these it stops the score from racking up and the noise, and then it continues later. It starts happening during play only.

I have tried first visually adjusting and inspecting each gap, wire, etc., and then basically bending every leaf switch away so there is no contact being made. I also read about the caps going bad (the resistor things that are there on these models to pick up light contact hits) and I tried cutting one and it made no difference.

It is the only thing keeping this game from being playable and I can't stand it. So much work and all brand new boards. Anyone have any suggestions on how I can diagnose or fix this further? It sat there mostly unplayed during the league night this month because the score just keeps beeeeeep beeeeep racking up 1000 at a time (faster now than before).

It seems like those switches are in a series (or two). I would have to take the series out, but at least that would narrow it does i suppose.

Just to make sure I am cutting the right thing, the large round red thing spanning the switches is the cap to cut correct?

Thanks Friend!
