Hi guys,
I'm a programmer without much EE experience, and I've got a problem that I might need some major guidance to fix. I do have access to some EE friends, but they don't have much lasing experience.
Last year I bought a projector from djpsych on PL; it's a 30 kpps, 2x red, 1x blue, 1x TTL green projector. That same autumn, both of the red lasers dropped in power to the point where they cannot be seen unless drawing only red onto a small surface area. I'm wondering how complicated and expensive it'll be to repair my reds. How can I diagnose the source of the problem, and what would I order to replace the faulty components?
Also, during some shows the power of the TTL green will drop in half or by three quarters. When I draw different geometry it picks up again. Is this indicative of future problem about to crop up?
Thanks so much!
(If anyone is in the Atlanta area, I might be able to pay for some hands-on help.)
