Hey guys,
A few months back, I disconnected my speaker wire from my so I could play at night. When I went to connect it back, the sound is so loud I thought my speaker (and eardrums) were gonna blow. I turned down the knob on the monitor… tried again… and same results. Even with the sound all the way down on the monitor, there is some harsh whirling/feedback sounds (like if you have a stereo maxed out with no music playing).
What is wrong? Is there another speaker knob I don’t know about? Bad ground? Something blown. Please help… the game just isn’t the same without sound. Also, I am a total amateur. So please explain in laymans terms.

Make sure all of the connectors are attached to the audio board on the monitor and if you have a multimeter check the volume pot resistance to see if the thing works.

Well, it works, right? I mean it's too loud, not silent? Is there something on the board that adjusts sound?

I saw a similar post about a DK jr. machine. The advice wsa to buy a new audio board repair kit from Bob Roberts. I guess I will have to do that. Is it hard to change one of these out?

Ill do you one better, I have 3 spare rebuilt already.
BTW I don't care how nice your audio board is, you can still pick up that noise.. a lot of people learned to live with that extra white noise.
I went on ebay and ordered 4 EZ20 audio extra rebuild kits filthy cheap.
takes about 20 mins to clean up the board and replace all the caps and shit.

It's actually really cool fixing these things. Yesterday, I fixed the joystick... a part I broke while fixing the joystick... installed the high score save kit and realized my monitor is an absolute beast, once I discovered the "brightness" knob.

Thanks for the help guys.
