Hello.
I have problem with synrad evolution 120.
Power supply RF 3000 stop working correctly today.
I think its problem with water pressure sensor.
Never work correctly (I hear noise inside case, when water flow). Now only Dc Input green light work. Ready and Cooling doesnt work, dont light up even slightly.
How to open the case?
The front panel or rear?

On laser unit also no ligt. Only beam cower, "click" to open.
