Check your TIP36 transistors on the aux power board. I had a very similar issue happen with my earthshaker. I replaced the TIP102 and pre-driver on the CPU board with no change. Went upstream with the 7402 and 6821 chips..no luck. It end up being a TIP36 transistor on my aux power board. While you're at it, you might as well check the diodes on the aux power board at the same time.
