    Smile Photo Synergy - DPSS Laser diagnostic and repair help

    Hello all at PL. LTNS and hope all are doing well!

    Can anyone help me to diagnose the fault with this 500mW DPSS laser please? It does it's usual power up sequence and begins lasing - maybe a few milliwatts for around 10 seconds, then stops. The power supply then gives some weak beeps. I turn it off and try again and it fails to output, unless I leave it to cool down.

    Does this sound like a dead diode or electrical fault (TEC or Thermistor). Any guidance appreciated please.

    ... try to get more infos for the "beeps" - there should be some "coding" with beep-counts for the respective error type ...

    Thanks Viktor. I've not been able to find any info online on the unit so far. I will pull the PSU apart and see if there is any evidence of deep fried components and do a little testing!
