primal rage sound
Question from Wayne: Hi guys ive come to you because im having no luck any where else. Ive joined some forums but nobody seems to want to answer my question. Okay here it goes i got my very first arcade the other day with primal rage pcb, the game plays really well in my jamma arcade but theres no sound, now on my search ive found out that the pcb has a sound board on top of the main board which i have. but there was no sperate wires that come with the pcb. So would you guys know how i could wire it up to recive sound. Also the top of my monitor has a bit of a wavey screen when playing thegame do you how i can sort that.
Thanks, Wayne
P.S By the way love the utube vids

Response from Tim: Hey I don’t know of a way to wire it up. The sound is in the roms which runs through the board and out the jamma harness so you probably have some bad sound roms. You can try to gently pull them one at a time and clean the legs of the chips good and make sure the top sound board is properly seated. You could also reflow the solder on the back of your sound board especially any that are yellowing or where main connectors go.
As for the wavy pic how far is the power supply from the monitor? I have seen them mounted on the ledge behind the monitor and caused similar issues. If you unplug the game board and just turn on the monitor for a while with a white screen does it get wavy?
good luck with your repair
Tim
