Replacing Laser PCB - worth it?

**modicullus** · 02-15-2006,11:21 AM

I've got a pile of useless lasers sitting around and saw that you can purchase new laser PCBs that I assume would bring the laser back to life (as long as the lens & coils are still good - right?). Here's a link to a current FleaBay auction for one - just so you know what the hell I'm talking about:

Has anyone tried these? How difficult is it to replace these PCBs? Is it worth it?

Thanks

not hard to replace PCB but only need if PCB is ripped . you need working laser Diode,lense,loop and bad pcb inorder to get it working. not that hard removig old one with dewic

Okay,... thanks crans. I was under the assumption that the diode was on the PCB - so all that really mattered was whether the lens & coils were still good.

yes if the Diode and lens/colils are good but the PCB is riped or damaged it shuld work

I went throught the trouble of installing a new PCB (got a system that had no laser response and noticed the PCB was torn). However, after installing PCB I still got nothing, laser does not move at all. I think I have the PCB in right, but who knows.

culd also be a blown fuze bad diode or bad rework
