I just recieved another LD 1500mw RBG projector today for repair.
Galvo Amp burned.. was 15kpps scanner set and was being used in a nightclub in portland. Software was set at 35kpps! (fb3). I was plugged in a ceiling socket with a light switch used to turn it on and off. The power spike caused the galvos and amp to burnup, the control board too. With NO SCAN FAILSAFE, it locked in white as the chicom control board fried. the galvo amp dies, and with no mechanical shutter the white laser shines into the eyes of a person there. Although the exposure was momentary, it did leave them with a solar burn on their retina that will take weeks to heal back.
When I tell him how much it is to put a scanfail and shutter, and it wont do the patterns anymore. The owner says, "thats how much I paid for the laser!!" I asked him how much it was for the medical bill. Hes replacing the laser. Medialas looks like the next candidate.
