Hey all,
I know this one has been discussed before but I figure it can't hurt to have another repair log and hopefully I can get his one solved without sending it for repair and maybe someone else will benefit. I'll gladly take any input as I'm no genius with repair, but I did get my Q*Bert sound board back from the dead so there's hope for me.
I have a Star Wars that has absolutely no sound, music, or speech in it. The only thing I get is a repeating thump noise and at times other digital garbage noise. So far I have verified the 2 eproms are good and all voltages are good as well. My next thought it to start swapping socketed chips and see if I can get get any change. The only chip I may have on hand to swap with is a Pokey chip from a working Tempest aux board with the 4 pokey chips on the Star Wars sound board. I did notice the numbers on the chips are different, but aren't all Pokey chips the same? Beyond that I was thinking about one of the processor chips being bad and I think I remember reading there are 3 clock signals on this thing as well and hopefully there are test points for them, but I'm sure there's other places to check them as well.
