I´ve been working on pins for about six years now. Fixing all kinds of stuff.

When I turn on my Funhouse there´s no sound.
If I enter the menu/diagnostics the sound turns on and no problem.

What I´ve done:
New batteries.
Reconnect all cables.
Reset to factory settings.
I´ve tried to find any kind of volume setting within the setup/diagnostic without success.

Any suggestions?

Well think I need to see if there are any relays for the sound board supply voltage.

Try reseating sound chip(s)? Maybe need a new eprom?

So you can get it to play ALL the SFX and music within diagnostics, but not during a game?

I had a similar problem but doubt it's related on my old FH. I got no sound when I turned it on but did in test just like you. If turned off and right back on it would be fine. I thought maybe a cap was going as it was draining and off and on was recharging it but I was way off.

It ended up being my PDB (As I sent the board out as I screwed up and wired in a flipper coil wrong and friend a transistor - they updated the board while in there, etc.) but not noticeable at first. I did a PF swap and came to be after that so I figured I had to have caused it. I ended up sending the board to the same repair place and they found some bad caps to replace, replaced the amp, updated sound ROM's, reflowed headers and checked fuses. Thought I was set and it still did it. Another local tech was able to figure it out the issue- Thanks Ryan! I don't do board work so I wish I could explain more but it wasn't what I would've thought.

Long story short, check your voltages and make sure that's ok.

Thank you dmacy, I read through the post you mentioned.

Will check voltages and see if find anything missing when the game is in this "silent" mode vs. when working.
Relays etc. as "thedefog" mentions.

This is a lot of help guys !
Thanks

No problem and good luck. It was annoying for sure.
