Hi Shaun, might pay to check a few components on the Z-Sus. See attachment.
What's the LED on the control board doing?
Don't forget the pattern generator on the control board. Bruce

How about cooking the main board - you might be on a bum steer. It wont hurt it and would eliminate one possibility.
See repair guide attached - it's for a different model but same principles apply.

Hey Shaun,
Does this set have a sub-power board under the main power supply, prominent because its populated by 6 biggish 3300uF 10V electros? If so, check C231 to C235 (all 3300uf 10V) and C205 (1000uF 25V), notorious for causing start-up errors.
