I own an InFocus Litepro 570LS. The projector light bulb blinks on and off.....I do not know how many hours are on the buld and the spare buld is burned out....what is a possible fix.

    Would this cause a rythemic on and off of the buld. The buld actually pulsates on and off about every 15 - 20 seconds.

Given that the bulb actually lights up and then goes out you need to check the contacts at the base of the socket to ensure proper contact is consistently made at the base of the bulb. Be sure to unplug the projector prior to inspecting and adjusting.

    The bulb actually pulsates on and off every 15-20 seconds....would a contact issue cause this type of response from the bulb. I would think the contact issue would cause the bulb to go out completely and not come back on unless jiggled to make contact again.

Do they make brighter bulbs for the LitePro 580 projector


Nope. You can NOT increase brightness of a projector by installing a brighter lamp. Sorry. The only option is replacing the projector with a brighter model.

Lp600 won't strike


If you replace the lamp but do not reset the lamp hours then the projector will not ignite the lamp to stop it blowing up the lamp and causing further problems. You can reset the hours without the image, on the x2 version you turned on for 1 minute then held down the volume up and down buttons for 10 seconds but all versions vary. The infocus website can usually tell you how though you may have to look for it a bit. Failing that try a firmware update available from the infocus website that should erase its brain so you can start again, hopefully you have kept the original leads it was shipped with to do this otherwise it will cost you another £20

Bulb failures


I experienced the same thing, only to discover it was the ballast that powers the lamp. I believe INFOCUS repairs for $390.00 per the technician that I spoke with on the phone at INFOCUS.

I can almost guarantee that your bulb is out. We probably have 20-30 projectors of this model in the school and bulb life averages a little over 100 hours even though they advertise 3000 hours. Infocus has been known most for their poor cooling system to the bulb over the years and most owners won't get the life expectancy of the bulb. If you remove the bulb you will find a small restrictive vent screen on the bulb and commonly it will be filled with collected dust. This model really doesn't have any removable/cleanable filtering system installed - again a cheap and poorer design then many other brands. We have decided not to purchase infocus projectors anymore in the district. They were a seller at one time because they were cheap, but because they don't last they weren't really a deal after all. Sometimes though a ballast for a projector will go out and it will be unable to power up a good bulb. I wouldn't consider fixing it because of their overall poorer reliability.  If your looking for a cheap but more reliable brand of projectors I'd steer towards Epson projectors. They tend to have lower costing projectors and bulbs then most and I have seen in person that they last well above their advertised lamp hours in different models. Their are many good brands out there but InFocus is not really one of them - they have under built projectors and poor phone support. 
Hope this helps a little. - Scott
