Projector Cleaning/Repair suggestions?
Projector Cleaning/Repair?
A while back I purchased a used projector off EBay, a Proxima 5900. When I got it, it had a severe case of dust blobs on the LCD panel (at least I think that’s what it is). There are numerous magenta colored spots across the screen and are very distracting during light/white scenes. I can bring the spots in and out of focus and there seems to be 2 sets of them. One becomes very clear when I focus on them and a 2nd set become clear when I bring it out of focus. I’m fairly sure they are dust spots and not dead pixels. I’ve done some searching myself to see if the cleaning was something I could do and found a couple sites that described how to go about cleaning the LCD. I could never figure out how to access the LCD on my projector.
On top of that when watching video I have a vertical yellow bar that appears on the right hand side of the picture and some of the picture has a barely visible yellow tint. I believe this mean something is out of alignment I’m not 100% sure I couldn’t find a correct description online .I have been meaning to get it cleaned and tuned up for a while but haven’t gotten around to it yet. My family has decided to build a dedicated theater room so now is the time to get it fixed up. I’m basically looking for suggestions on where to get it cleaned up and repaired. The home theater room is on a tight budget so the cheaper the better but I want the job done right and well.
I’m looking at Projection Solutions right now as my first choice. It will be about 300$ to do a full tune up. http://www.adtech-sys.com/content/repair.asp#fourpoint . I haven’t done too much in the way of comparisons so I’m hoping you can help me out with that. Any and all suggestions are welcome!
Thank you for your time.

I've opened up and cleaned many of my LCD projetors. It's possible to really screw stuff up though, so you have to be careful.
You probably have to unscrew all of the screws holding the top of the case on to get to the LCD panels (not just some easy to find/open panel).
You should find a high quality can of air, perhaps from a camera shop. Empty out a bit of the air on a pair of glasses or a window. Make sure there's no particles or liquid. When you spray the LCD panels, do so from far enough away that you don't get an liquid on them, at the very least 6-8" away. Always hold the canned air UPRIGHT.
