MVS 4-slot and uptone sound

[viaton]

Hey you MVS-Gurus out there!

Please help me on this one:
I own a 4-slot which has a disturbing uptone background sound. During game demos when the game changes the sound goes a bit higher or a bit lower. I have tried to change the places of the games and it did not help in the matter. Could it be something with the mini-marquee lights? What the heck is wrong with my cab or is it my head (again)? wink
Thank you for your help in advance!!

I'm pretty sure this is normal with certain games..
I'm no tech..but some of my MVS carts sound louder then others in the cab..
Metal Slug-3 is one loud game..

Crossed Swords sounds much lower in my cab..then other games.

No, the sound I mean is coming from speakers directly and not depending on the game. Very high sound which comes all the time when I play. It is not a sound of the game. Sounds more like some kind of electrical fault to me???? help

Ok..Tell me something..Does all of your Marquee lights work..?
Are any of them out?..blown,not working..

If any of them are blown out then the sound may be coming from them..

You have to disconnect the Marquee lights and see if this is the problem..
Behind the lights there should be a small box that these lights connect to,disconnect that..and see if the noise goes away..

I'm going to look for a picture of that box and post it.
