Quoted from remf:Ground mod was done, but I haven’t repinned the connectors except for the big one connecting the mpu to the driver board. I checked the others and they seem fine, but who knows... and you might be right because I got the sound board today and still no sound. the main reason I bought the sound board is because the tech who got it up and running said that was the issue so it serves me right for listening to him. Lol, anyone need a working sound board?
Also, I tried to see if the manual would tell me what size/type of connectors I need, but I couldn’t find anything in there. Any suggestions as to where I can find that info?
If repinning doesn’t work then it has to be the driver board because i already tested the mpu board in another machine and it worked fine.
Those stupid connectors are super hard to find right now. I used to be able to get them from Great Plains but he was out of stock and basically said the last time I looked that they were impossible to find. Someone will probabaly chime in with the exact pin info but I thought they were 156 bifurcated. They might be found somewhere. If so, I’d like to know myself. There isn’t much hope for a ton of these gottliebs without being able to replace the connectors
One more quick place to check with a sound issue is the power supply. I have had cold solder on the pins of that little power board right next to the sound board cause sound issues too. If I’m fact the edge connectors are ok you might look to the power supply and see if you are not getting a connection there.
