http://peterunderdog.com/arp/repair.html

is another starting point.

The beauty of the Omni is that large parts of it can be "debugged" one
after another.

Check power supply and power on boards.

Check master oscillator.

Check divide-down circuitry.

Check gating circuits.

and so on.

Repair-wise it's really a "one step at a time" synth; and that IMHO makes
fixing it a bit easier than synths with a myriad on dependent functions.
