To me sounds like some of relays is not working. will advice to do hot gun job first and re-solder all relays. (white square boxes)
Is not something which you can test yourself. Each relay works only when is simulated only certain protocol so you have hundreds of combinations. Reassuming, without protocol simulator only way of testing them is measure ohms and checking if they click and reconnect signal. Make sure that you have knowledge how to use ohm meter, and you have stable power supply of 4.5V. And make sure ‘+' goes to correct place. Otherwise it will be costly repair.
Then check caps with beep scale, if its beeps and number is same as connected two tester pin, then you are close to fault. Hitachi xl2000 drivers for mac pro.
