Hey guys! Need some help here as I'm running out of options. So my Hook has this weird problem where the switch on the left ramp seems to cause some kind of break up in the audio with some nasty pops and cracks, but all other game sounds work fine. It's been doing this since I bought the game over a year ago, now it's been completely shopped and everything cleaned the game works brilliantly apart from this issue which persists.

Here's a video showing what's going on:

What you may notice is that the ramp sound plays fine the first 2 times. It seems like it doesn't start to happen until the machine has been on for a few minutes.

Here's some things I've done so far to try and fix the problem:
- replaced the switch diode (twice)
- re-burned the sound roms and the game rom
- checked and cleaned all connectors
- re-capped the entire sound board

So with the problem persisting after doing the above I'm now at a loss. Any suggestions?

Anyone?

I've now replaced some of the main IC chips on the sound board. Still having the same problem. Wish I could track down what is causing this.

You sir are a genius! Thank you!

It IS indeed the rope lights. Disconnected them and the problem vanishes. I also do indeed have an XPIN power supply which I bought brand new for the game a few months ago. I've checked it, and it's the Revision E board.

So, I'm now at a loss as what to do about it. I'm not prepared to fork out for ANOTHER XPIN power supply when this one was bought to supposedly get my game running again.

And to think I spent all that time and money replacing components on the soundboard. Grrrr!!!

Amazing stuff dude! So is all of this in addition to the board fix discussed earlier in this thread?

Yeah dude! All fixed thanks to you!

I did all of the fixes you talked about above. Removed the VR3 regulator and replaced the capacitor.
