I have a Whirlwind on location having a weird issue.

It gives one regular bong on boot up, but never goes into attract mode. Loud feedback hum.

I poked around a bit but it suddenly worked perfectly and I never figured out what presumably chip or connector was the issue. It’s humming and not fully booting again a few days later. Any ideas? The feedback hum is super weird!

Quoted from RonSwanson:

If you turn it off and back on again quickly, does it boot normally?

Will give it a try. What would that indicate?

#4312 2 years ago

Switching it in and off does nothing to change it’s hang up. Also see a garbled screen sometimes.

Then… it just works. For hours at a time.

Reseated ROMs on MPU and connectors, no effect. Getting 5V at MPU, LED indicates that, but diagnostic led flashes endlessly when the game decides not to boot.

#4314 2 years ago

Interesting! I’m going to swap the MPU out with an astronomically expensive Rottendog and if that solves it, I’ll work on diagnosing.

Bought a replacement for the the single drop target bank board:

https://ksarcade.net/system-11-single-drop-target-opto-board-c13311.html

Can anyone confirm the original board doesn't have a diode? Schematics for the original show a diode. The other three target bank has 3 diodes.

Someone hacked a Cyclone drop board into mine so hard to verify what the replacement should have.

#4377 2 years ago

Anyone who can take a peek at their opto board for the single drop and let me know if there’s a diode — I can’t imagine there’s not, it’s a matrixed switch like any other. Super confused about this replacement board…

#4380 2 years ago

Thanks so much! Actually I meant the diode for the opto switch, I can’t figure out where that would be if not on the board — it is a matrixed switch like any other…

There’s a diode in the schematic over the row/col pins

I didn’t even realize the dotted line indicates the sensor housing. So if that’s the case (it’s unlike the 3 drop board with through hole diodes right on it) then I bet the incorrect Cyclone board that was in there doesn’t have a diode in its sensor. Hmm. I’ve never paid attention to or seen an opto sensor with a diode inside. Anyway throwing in the replacement today.

Does WW cancel ball search when holding a flipper up? Tournament organizers are asking about ours on location — reported that ball search was happening while trapping a ball so not sure if that’s normal.
