Pool Sharks wont boot - R.I.P - Williams system 11 - no diagnostics or blanking

You've proven that the reset circuit is working.
Good first step.

There are many possible causes for what you are observing.
Too many to walk a (forgive me) newbie through.
You would be well served by sending the board to one of the pros to repair it.
Clive, Rob Anthony, or I can fix it. There are others of course.
LMK if you'd like to ship it to me. I have the System 11 test rig fired up.

Quoted from DocRotCod:
Look how many guys offered to help fix your original board. Look how many people would step up to fix an aftermarket board. It's the same reason I prefer a original MM over a remake.

Bingo. Some time in the future, we'll need to be repairing these aftermarket boards, but not quite yet.

Quoted from PinballManiac40:
For $200 or less, you should be able to have your original MPU and power supply repaired.

Easily less than $200.
The general base rate for System 11 MPU repair is $84.

It's not uncommon for the HV section to fail.
I'd definitely get that board repaired as they are much more reliable than RD power supplies are. If you go aftermarket, XPin is a good one.

Could be a cap like mentioned. Someone might have put it there to abate arcing of the relay points. Not needed, but not a terrible idea.
