Fadal just went black

[Houndogforever]

Just sitting there, been running for months. Everything went black. Screen turned off, work lights went out.

Amplifiers are still flashing, drives are dark.

Rear cabinet the inverter is lit up like normal, but nothing happens when you push the green button.

Any ideas where to look and start troubleshooting this?
Thanks

You should know the drill by now.. Low voltage power supply..

If you've got nothing coming out of there. Swap the relay (domino) with
one of your coolant relays.

Actually hang on a sec.. Work lights went out.. That should be 120, and
have nothing to do with the low voltage power supply. Check the voltage
coming out of the transformer. Actually, check the voltage coming into the
machine.. Had a transformer get hit by lighting once, and weird things happened. Machine
was behaving sort of like you are describing. The high leg was fine, but both low legs
were at 77v..

seems like one of the small transformers on the amp chassis board cooked.

I'm trying to figure out if I can by-pass one and just have 3 axis rather than 4.
