Question about InFocus LP120 / 1000 Lumens / XGA / DLP Projector Refurbished Multimedia Projector

1 Answer

Lots of details: LP120 stays on for a minute, then powers off

I know, seems like it's the same problem many times on this forum!

Here are the details:
Bulb has 527 hours
Projector powers on, solid green light.
Stays on for 1-2 minutes then powers off; no change in LED light colors - stays solid green
Have blown the projector out with canned air - a bit of dust was removed
Swapped known good bulb into projector - same results
Have also seen a slight bit of image "jumpiness" before unit powers down.
Color wheel appears to have no problems/cracks

Ideas?

Either the colorwheel motor is not getting up to speed to sync with the dmd chip, the wheel sensor is going, or the power supply needs replacing. you can try to replace them yourself or send it to an infocus authorized service center. try www.avsolutionsny.com . they're pretty good.

InFocus LP120 Powercycles/Shuts Off/Does Not Stay On


what is the led doing? what coloris it? and if it is blinking, how many times? this will tell you the problem.

green (flashing and solid)- all is well
red flashing:
1 time- lamp won't strike after 5x
2 times- lamp has over 2000 hrs. replace lamp
3 times- lamp failure. replace lamp
4 times- fan not working.
5 times- projector running too hot. needs cooldown
red led lit solid- undiagnosed issue. send in for repair.

if your projector is under 2 years old, it's under warranty, but it seems unlikely.

I have had the same problem for years since I bought he car used. When I use the extra set of keys, it does not seem to like them. No problem with regular keys though. Go figure.
