magician lord with sound issues

so i recently bought a magician lord on ebay, and when i went to boot it up the game starts and plays fine but the music is totally crap. it sounds like static or white noise. i checked it in the universe bios jukebox and i get the same thing. i tried cleaning the contacts with alcohol with no luck. any ideas?

Clean the contacts again, but this time with a pink eraser.

Check traces and solder joints.

opened the case today to check solder joints and i found a solder bridge between two pins, so i fired up the soldering iron and now it works great!

Glad to know you got it fixed. =p

Hey guys, sorry for the thread necromancy, but I'm having the same issue with a Windjammers. I've touched up any possible cold solder joints, I removed a solder bridge, and I completely cleaned all the contacts, with an eraser and with contact cleaner -- no improvement. The game plays fine, but the sound has intermittent static bursts.

It's not the cabinet because other PCBs are fine. It's not the motherboard because other MVS carts work fine.

Ideas?

EDIT: Fixed by cleaning the contacts AGAIN and resetting the motherboard memory AGAIN. Sounds great now.
