White has a purple hue

[Mikey851]

One of the RGB projectors that I have is giving me some problems. When I first got it the white looked great but now it has a purple hue. I would say it was because of cheap components but since it was good once upon a time I'm thinking something else is to blame. Sorry if this is a stupid question I'm just now getting into this stuff. I'm assuming it has to do with one of the filters.

Sounds like one of your green lasers are starting to run a bit out of tune, or degrade. Have you tried just projecting a solid white frame for a while (15 mins+) and seeing if the good white comes back? Green lasers are a bit of a pain to keep stable.

Yeah lack of green will cause a shift towards purple (red / blue).

My green doesn't modulate very well so I'm seeing the same when a BAM is applied and power reduced. The red / Blue hold up fine but the green fades fast.

I will check a few things out and see what I find. Thanks for the advice.

get the EYEMagic IRIS system. IT fixes those problem.
