Help with Galvo's!

[kamakajee]

Hello All,
Had posted the below post in 'Modification'.. but didn't receive much help.. hope I could get some more response out here
The projector is from MediaLas, model Mistiqe
All the help will be much appreciated.
Thanks Kama
"Hello All,
I'm using a 2.5 watt RGB laser projector purchased from Europe. Now it seems one of the galvo mirror is not working as I get a straight horizontal output line. It is pretty expensive to send the projector back & forth to the manufacture.
My concern how do I repair/replace the galvo?
Can I change the galvo at my end or is it a MUST to send the projector back to the manufacture.
Do I have to change both the galvo's
How do I know what type of galvo to order (any physical mark on the part),
Any precaution be taken to make these last longer (this is the 2nd time within a year that these galvos have gone off).
All the help is appreciated"
Thanks Kama

Hi Kama

You now for sure is the Galvo?

You check: fuses, cables and amps?

Switch the amps cables to see if change something.

Try to help to locate the culprit.

Cheers,

Yes shipping back and forth expensive , so you are going to HAVE to learn unless you can find anyone local on here with expertise
who can visit etc

When i joined here I didnt know what a galvo was , been a steep long learning curve but needs must !

SWAP the galvo leads from one galvo to another as megaton explained , this will help troubleshoot confirming
that the issue is indeed the galvo and not some other problem

If the galvo is faulty , might be cheaper to buy a new set depending on what galvos involved rather than repair

certainly a LOT cheaper to send back a single galvo than whole laser

Sorry , your gonna have to get your hands dirty , get that lid lifted !

Thanks a ton guys! appreciate all the valued inputs, special thanks to taggalucci.. you sure pointed me to the right direction.
In case if I have to change the galvo.. what price am I looking at.. any Ideas as to how much they cost & from where I could get them.
thanks,
Kama

Please can you post good, clear pictures of the galvo, the amp(s) and the wiring between the galvo and the amps? It will be much easier to help you with a better idea of what MediaLas used in this model/what alternatives could be used that would be compatible with what you currently have.

pricing depends alot, scanners start at around 100 dollar up to 3K
mayby medialas could make a special deal for you because you own one of their projectors or mayby even get it for free under warranty.
replacing a scanner / drivers isnt that hard to do if they arent glued into place

but please upload a picture so we can see what you would need.
