Re: Infocus IN26 Projector

Yes the problem is due to over heating.It would be perfectly acceptable to have inlet air to the projector that ranges between 70 ? 76 Farenheit. Most projectors are designed to operate with inlet temperatures well above this value, usually up to about 90F.Set your air-conditioner to the value specified and it should work fine..

My Infocus IN26 has less than 900hrs consumption but the resolution is almost blurred.

Is the lens kept clean and the optical engine cleaned regularly. Is it used in a smoky atmosphere?

How do I replace the ballast in an InFocus IN26? And while we're at it, where do I get one? I've already replaced the bulb with a new one (direct from InFocus), reset everything to factory settings, and...

remove the front and rear bezels, remove the top cover, take a picture of the location of screws and ground wire on the metal frame. remove the top boards, remove the metal frame and there is the ballast/power supply. pay attention to the way the cable is routed to the lamp connection, also pay attention to which way the connection from the ballast is seated in the lamp housing. hopefully a new ballast will fix it for you, as to where to get one, that's iffy. you could try to find an in26 on ebay that has other problems but has a working ballast

Power in cable, but projector is dead - no light, no fan.

bad power supply. you can get the part from an infocus service center, or send it to them to repair. either way, try av solutions in ny. they're really good.

InFocus IN26 overheating

clean it out. use canned air and blow the dust out of it. sometimes after many overheating issues, the temperature sensor needs to be replaced. but first clean it out and make sure the fans work well. if they spin slowly, replace them.

Infocus in26 fan runs continually

The fan does run continuously on this projector however it should be running very very slow when the projector has completed it's lamp cool down routine.
The reason for this is that a portion of the switching power supply remains energized (running) when the projector is at rest. But as I mentioned it should run very slow in this state. If it remains running full blast then most likely the fan speed control chip is shorted which can cause fail 2 ways, either the fan 1. runs full
speed or 2. remains stalled (then the projector will go over-temp and shut itself down) I hope this answers you question.
