hi keith
we have an infocus lp290 and bought a replacement bulb online (from TRATECH Switzerland) after a long time. I have just fitted it in and the beamer turns on then the green lamp blinks and after a couple of minutes a single beep sounds and then the beamer seems to attempt to power up again or at least it seems as the green lamp starts blinking again, BUT no light comes out of the beamer lens ie: the bulb is not turning on.
have you any ideas what the problem might be?
thanks for your time in advance

I have an Infocus IN2102EP with a white blob of dots on the left side of the projected image. I have replaced the bulb and tried to blow it out with a dust remover, but the blob is still there (looks like the color is faded out of the blue). Any suggestions on this problem or how to fix it? Thanks!!

I recently bought a LP280 and was having random shutdown issues. After reading some of this and other places I decided to dig into the thing.
I just use it for outside stuff so I removed the filters. I also removed the main board and discovered the power supply(right side looking from the top rear) was not seated down fully in its slot. After reseating it I cleaned up the edge connector to the main board and reattached all the connectors I removed .I also removed the thermo sensor from outside the light housing (scary, I know!) It’s now hanging inside the case but not directly on the wall of the lamp housing. This may have been my problem. Anyways it’s now working reliably. Probably a aftermarket lamp I dont know but at least it works for now, and if it burns up we can have a campfire after the movie. LOL

Hi guys! I eventually managed 2fix my problem! It took me a really long time 2fix this yet the solution was so simple!!! I’m posting this for the sake of those who might find themselves here hoping to find solution to a similar problem. Anyway, the solution was just to clean and oil the fans!!! Surprisingly, mine weren’t dirty and they werent stuch either, but oiling them did the trick

I was given an old infocus Lp250 by a friend, the problem is that it gives an error message that one of the fans is not working. I have a little knowledge in electronics so I took it appart and tested the fans with an external 12v supply, they all seemed to be in order. I took an electrical meter and measured the voltage on the fan connectors only to realize that the rear and the front left fan were not getting any voltage, so I tested the components that are inline with the fans circuitry only to realized that two surface mount reistors were gone on both fans circuitry. I replaced them with ordinary resistors of the same resistances n powered the pj and presto, it worked. i tested it for a few hours turning it off and n off inorder to be sure it’d work and all seemed fine. I took it appart again so that I could screw everything back in place because I hadn’t put in all screws, I turned it on and… the fan error came up again. The resistors I replaced are still fine according to my meter but still it wount work, the lamp has done 101hrs only by the way, am stuck, someone please help.

Hello keith just to let you know i have got the parts and soldered them in and all seems well thank you very much as it seems to be a successful fix so far. I have however got one question as i don’t have any knowledge of projectors what so ever, i was wondering if you could help me, i seem to be getting a blue line on the left hand side of the projection. Any information would be useful.
