Ran into an issue with HH tonight, looking for additional troubleshooting steps. The symptom is no sound at all.

Game and Sound was working, Fuse f2 was blown and game wouldn’t boot. Replaced f2, game booted but no sound.

Fuse F8 is good and has correct voltage
All the test point voltages on the sound board are correct.
reseated all connectors (multiple times)
flipped the background sound dipswitch off an on
Tried different positions of the volume pot

Still no sound, any ideas would be great.

The test button on the sound board doesn’t seem to do anything. I’m assuming that means the problem is likely the sound board itself?

Doesn’t seem like there are any replacements available while I work out what’s wrong with this one. Anyone happen to have a lead on one or any other thoughts?

I found an extra sound board from black hole, can I use it in my haunted house with no sound?

I’ve heard they are different boards but they look very similar if not the same.

Just what I wanted to know, thank you!
