(OP)
It started this morning out of the blue. I could not to start the machine always getting alarm 4076: Laser power down. when I looked at diagnostic page when starting power goes up to 600 at stage 27 then alarm and power goes down. Any ideas what can cause this problem.

Technicians removed and replaced the circuitry and power diodes.(Resonator)
You must call AMADA technician.
I hope it will answer.
Luck!

The problem could be as simple as a bad power sensor. You can measure the resistance of the sensor; should be around 250 Ohms.
It could also be a bad laser gas (maybe try a new bottle, making sure the specs are correct for the type of resonator you have; they are not all the same).
Could be an internal leak. Do an internal leak test. Do also an external leak check.
Or the optics could be dirty or misaligned (mode issue). How many hours do you have since last optics replacement?
Usually, if a power sypply or matching box is bad, you would get a 4063 alarm.

Strange.

Can you check if the power LED is on for PSU2 (on the PS Unit itself)?
Not sure how that would change by itself, but maybe check param 15027 bit 1, make sure it's on 1.
If the power supply was the cause, that should usually give alarm 4063. Did you get that alarm at all?

Chiller temp. 78 watter pressure 55. O2 pressure around 40.
