I have a 1290 ES 80W laser and It gave up on me right in the middle of a deadline. I was cutting acrylic and all of a sudden it shutdown.
Took me a while to find the 15A 250V fuses that I changed. It turns on now but doenst want to fire. I noticed the little fan on the power supply wasnt turning it doesnt "beep" like before when I turn it on. There is also another fan on the other side that stop working. Do you think there is some kind of electrical short? or need to replace the power unit?
