I have a Speed Buggy arcade that was working perfectly up until the other day. My brother and I were alternating turns, and while he was playing in mid-turn the sound suddenly just disappeared. I tried adjusting the volume, no sound, not static. The test screen says all the hardware is good. Can anyone help point me in the right direction in diagnosing or fixing this?
 
Its been a while since I have had a SB so lets see if I can recall anything about it...like where stuff is.

I want to say the board (main board) had like 4 or 6 channels of sound. The same hardware was used in a multi monitor set in setup. There are individual sound pots in the main board for each channel. All of that ends up on a satellite amp board where the multi channels are mixed into 2. One above the monitor and the second in the front of the cab. The master volume pot controls how all the individual channels are amp-ed in unison by the satellite amp. If it all died at once I bet its in the amp.

Open the CP and look down toward the bottom of the cab. On the right wall just above the accelerator pedal is the amp board. The one I had just had a harness running to it for the power and carrying the audio off the main board. Neither were tacked to the cab so they swung free. The headers on mine were riddled with broken solder joints. This is a good time to check for a loose connector and for correct voltages. If you remove the connector mark it. I want say there were some unused pins and no key. In your case the connector may have just worked its way loose. Since you lost everything, not just a channel, I am betting you lost power, connector is loose, broken solder joint(s).

I would also look at the board on top of the pedal assembly. Mine, like the audio board, had a harness just hanging off of it. I found broken solder joints on all the pins. I have no idea how it worked.


Oh..it also just occurred to me that factory mine had 2 power supplies. One for the 5V side and one for the 12V side (I think, again it has been a while). I think the 12V just routed to the amp board. You may have lost it. It is is a supply...well...go big or go home. Those boards have a decent power requirement. I ended up (nicely) replacing both of mine with a fat PC power supply.
