Howdy Folks

About a year ago I got my Maharaja Pachinko 2006 model out of storage in my apartment and sadly when it went spinning on the screen No Audio from any of the Four speakers

I checked All the cables and sockets on the board but they are all in great shape. I did move the back audio switch to All it's three positions and no audio .

Please help this old pachi tinkerer . Many thanks in advance
