I just got my leadlight glp 105 in the mail, it worked fine, when i went to pop the button for the pot to be visible, it came off with ease. When i pressed the button for the laser to turn on without the plastic piece in it, it went on but about 2 seconds later shut off, and will not turn on again. This is before any touching of the pot... If i press the button there is a small green glow inside of the laser casing but nothing actually comes out of the laser lens. I tried to turn the pot or whatever, please someone please get me on aim or respond here.
Sounds like something is blocking the beam if there's a glow. You'll probably have to take it apart. How you do that is dependent on what model you have. I think on the 105 the end cap is just friction fitted, so with a bit of "coaxing" it should come off. After that you should be able to slide the module assembly out. At that point hopefully you will be able to just see what the problem is.
1.- Without turning the laser on, look inside the aperture and see if there's something blocking it, maybe behind the lens. Don't do that wiht the laser on, even if you don't see any light.
2.- put the laser infront of a digital camera and see, through the camera, if there's any IR light being emitted from the laser. If there is, then probably the crystals moved somewhat inside.
If this fails, you'll need to open your pointer and take a look inside. My guess is something moved inside, probably the diode or the lens, and it's preventing the light from exiting through the apperture.
Another possiblity is that you have a 110, with the green led inside the case, and that's the green light you see when you press the button. That's a far fetched possibility, but possible nonetheless
Either that or you shorted out the diode by pressing the button and touching the case.I really doubt it because you say it happened in about 2 secs. but I have seen lasers short out that fast.Well good luck.
