Just picked up a Make Trax... that has a sound issue
Game plays just fine - but the sound is screwed up.
I will try to explain... I credit it up - hit player one - and the music sounds like a radio station that is BARELY dialed in... you can tell that its intro music - but the sound is wrong and staticy... Any ideas of what to check? How to fix?
download this manual first if you havent already got it

turn off the game. remember to turn it off at the wall socket. mains voltages are present in the game and are dangerous for the unwary.
staticy sound could be a few things - start at the speaker. Page 12 shows the cabinet wiring diagram and as you can see there should be a series of connectors between teh board and the speaker. check em all,
and check the wire connections are solid. trace the wiring from the speaker back to the board and check where the wires go into the edge connector are also solid. pull the edge connector and clean the fingers on the edge of the board in the same spot as the wires from the speaker. if you see any loose or broken wiring, fix that first.
turn on the game.
page 4 of the manual shows the board layout. in the lower right hand corner, you shoould see a roound symbol marked VR1. thats the volume control on the board, so have a look at the board and tweak the volume control to see if changing the position gets rid of the static. if that s so, you may have a faulty volume control pot.
turn off the game.
also on page 4, at the upper left hand corder, you should see a rectangular symbols labelled 1M, and 2 to the right, one labelled 3M. these are the roms that DOkert referred to when suggest5ing you check if the correct roms were on the board. it is also possible that these chips may be loose in their sockets. if you slide a piece of wood the right thickness underneath the board under those chips, then try pushing them firmly into their sockets, and remove the piece of wood. careful you do not bend the board at all during that op.
turn on the game.
try the game again.
report back any change!
