Is laser replaceable?

[Allyn_Skelton]

The laser on one of my garadgets is no longer working. Tried reboot, delete and reinstall, etc. But no laser beam.

Yes, if your unit is out of warranty you can try replacing the laser at home:

Low reflection low laser

Yes, I warranty all items for a year. From your responses it sounds like you will have no difficulty with this particular fix. Here are the process: open your unit and remove the PCB. It’s all once piece. pull off a plastic spacer holding laser and photo-transistor in the direction of the laser don’t remove the leads from PCB, instead heat up the ends attached to laser one at a time leaning the laser away until completely separated put the new laser into the spacer and slide it back onto PCB s…

My laser has stopped working as well. I have removed the laser and expect the new one to arrive tomorrow, however, when using the multimeter on the laser terminals on the PCB, I do not have any voltage. I have voltage on the camera but nothing on the laser studs. Shouldn’t there by ~5v to the studs in the PCB?

A&D = 0v
A&B = 0v
A&C = 4.9v

The laser is modulated with the three short pulses every second. Your multimeter will not be able to detect that. To see that you’ll need the oscilloscope and some load so the current can flow through the transistor (actual laser or equivalent resistor in its place). Anyway, you can just go ahead with the laser replacement and not worry about the measurements.

Thank you for your respond. Helpful to understand why it wasn’t reading. Hopefully the new lasers arrive and work after install.
