challenge 305 cutter

OK - not exactly a press problem - but…

I have a challenge 305 crt that no longer operates. Overnight it went from a normally operating machine to:

The screen stopped working. All buttons related to the screen either are dead, or in some cases just beep. Air pump does a constant off/on. Hydraulics and oil cooler are dead.

I have the owners manual, but it is a little short on the info I need. I would like to know what the input and output lamps should be doing when the machine is waiting to cut. Also, what signals I should expect to see between the crt controls and main board.

Any of that would go a long way to solving this problem.

Thanks,
Gary
