Munsters (Pro)
Stern, 2019Munsters pro on route, game sitting in attract mode and the speakers emit a pop noise over and over. Reseated plugs, still does it.
Code is 1.02 currently and I see 1.03 has a mode board update and audio fixes. I’ll try that soon.
But has anyone experienced this pop?
Edit:
From a cold boot it does take ~7-10 min for the popping to start. So it would seem like a bad solder joint or capacitor...
Quoted from grumppy:I know you stated the sound is coming from the speakers, in the video it sounds more like a small coil firing.
I verified it was speakers. Folded the speaker panel down and held my finger on the speaker. Also via listening. And it sounds like a speaker pop/crackle in person.
I can’t help you but I was on a location last week with 30 plus machines and sure enough the Munsters game speakers were popping during attract mode. It was annoying! I just wanted to let you know it’s maybe a Munsters thing and not just bad luck on your machine.

Dang! Hilton said he remembers it being a Munsters thing too!
So the notes for 1.03; are very audio heavy

volume is restored.Added Standard Adjustment "MAX PLAYERS PER GAME". Values are 1 to 4,
with a default setting of 4. This can be used to limit the number
of players that can be added to a game.
Update:
Holy crap....
So I updated the game to 1.03 today. While it was updating you could hear the audio popping. Once the game rebooted and the node boards did their updates.....No game/music audio what so ever. However still audio popping.
I have unplugged CN2 aka backbox speakers and now it does not make popping noises but no audio....great...
I should update
The cpu carrier board has the audio circut. And that failed. Stern had me work with the distributor and replaced my entire cpu/carrier board. Even out of warranty. Which was nice as that is a $600 part as they include the cpu and carrier board. IMO they should sell the carrier board separate. However if they would now replace under warranty I was going to desolder the components and try to repair.
All is working after that.

Thank you for the update. This will help me fix my machine.

Use your distributor and have them contact stern about a replacement. Our game was well over a year old and they covered the part.

I will. Thank You!
I’m really hoping someone tries to fix one to see what actually failed so the community can document it.

Had this same exact problem on my Beatles, but thankfully stern covered it under warranty (since I bought the game somewhat recently).
less than 2 months later I had the same exact issue on my star wars. Never seen the issue before that, both games were at different locations.
Both games were made in the same year as your munsters mid-late 2018. If this is a thing, I have a couple other ticking timebombs 
.
Since this one isn't under warranty, I'm going to try to repair the CPU board at some point. I think... maybe I know what it is, just hoping I don't rip off the pads in the process.

Stern replaced the board under warranty over 1yr after so I would ask. They just made me go through the distributor to do the swap.

maybe, I was told no when they thought my beatles was the end of 2018 (born date). but when I said the actual purchase date was closer to 2020, they were cool with it. I bought star wars in january-2019, so I'm not sure that's over 2 years now. guess it can't hurt to ask.

yup that's a no go from stern. I'll update it I ever figure it out, was going to buy one of those headphone things to see if its only on the main output alone. If so, that isolates it to like 6 components.

stern told me no, they said to call my distributor. Did you hit up the distributor?

Na, at this point I'm not going to worry about it. It took a while for the last spike 2 cpu warranty to get fulfilled. Plus I have two other legit issues on other games. One is a broken topper, another is for a factory shorted shaker motor (which blew out 2 other boards).

Ufff, not the best luck with spike. Well the schematics are online now, and it has the audio circuit. I think if you test/replace some of those you’d fix it.

Well given their track record, it's not been to bad. Got 16 location spikes, even with these hiccups they are still pretty easy going.

I’d agree, and their new pros are pretty easy to work on. I had the opto ramp issue on Munsters and the gate fix for Jp otherwise they just run….
