Re: InFocus ScreenPlay 4805
Have you checked with the manufacturer regarding a firm ware upgrade? There was an issue with this at one point. Make sure to contact them directly. They can either mail you a cd version, direct you to where it might be on their website, otherwise email it to you.
They are able to fix that problem which my sister and my other sister/brother in law also owned this same pj had to do the same thing.

the light tunnel under the colorwheel has collasped or the projector has been jarred, knocking the mirror inside of the lens assy. out of alignment. Either way, it will have to be repaired by a technician.
The fan is probably on it's way out and cannot produce enough air flow to cool the lamp. Replace the fan with the same ratings as the original and it should work fine. The only other thing would be a problem with the power supply not supplying enough power to the fan, but, a bad fan is more likely.
Is this the first lamp you have placed into your Infocus pj? If not, did you reset the hours when you did it last time? Otherwise that can also confuse the projectors internal system thinking there is NOT a new lamp in there and there for make it stop working once the clock hours are expired and over the 3000-6000 suggested hour life.
Let me know so I can help trouble shoot other possible problems.
Contact the manufacturer for a firm ware upgrade. My two brother in laws/sisters own this same pj and had the same issues you are talking about. Once they installed the update [aka: firmware upgrade]it created a solution to the problem.
Let me know how it goes. They can either mail you a CD, direct you to where on their website, otherwise email you the update to download. You have to connect your pj as well.
Let me know how that goes. I'm fairly confident that will fix it. There was a certain time frame [manufacturer dates], and serial numbers that had these issues.
