Don't do it! I hate to say it but it doesn't sound like you got a good buy unless you paid a big discount. It sounds like a good candidate for a maintenance trip to the manufacturer or repair shop but only if they are experienced with projectors! It sounds like the LCD panels are bad. $300 sounds like an awful lot for a maintenance tune up - however if this includes replacing the LCD panels it might be okay. This is an old projector, you would be better off putting $300 towards a new projector. This 5900 only has a resolution of 832x624 and is a multimedia projector. I think you would be more satisfied with a new projector or a used model of a newer projector specifically designed for home theater use. Bottom line: the LCD panels probably won't be replaced for $300, and $300 is too much for a "cleaning" only. Ask projection Solutions specifically whether replacing the LCD panels is included in the $300. If not, then don't waste $300 on it, it's total value is not worth it.
