Question about InFocus SP-LAMP-LP5 Projector Lamp for LP580 SPLAMPLP5 SP-LAMP-LP

1 Answer

Infocus lite pro 580

Image brightness fluctuates from normal, to bright. Thought over heating was the cause, as the filters were very dirty. I disassembled and thoroughly cleaned entire projector, and replaced both filters. No change, very irritating, Help me please!

Have an infocus litepro 580, lamp and speakers works fine. Projector will only show the "infocus systems" opening display without changing to my video source. All cables are correctly in,...

Go into the settings menu of the projector and turn off the auto source function, then select the input that you are using.

if using a laptop you may have to simultaneously press your FN and relevant 'F' key to send the signal out to the projector. The 'F' key usually has an image of two side by side monitors or it says LCD/CRT. Wait a few seconds each time for the signal to be sent to the projector. Sometimes you may have to repeat this action 3 times to get the image on both your laptop and your projector.

good luck

The image is very dim, even on maximum brightness. We are considering replacing the bulb, but bulbs for this projector are very expensive and we suspect that since there is some image, the bulb is not the...

Yes, as bulbs age they will begin losing brightness. Most projectors have a bulb life hour clock, that measures the number of hours a bulb has been used. Usually you can pull that up within the menu of the projector. Also that particular model has what is called "Eco-Mode" and when engaged dims the bulb by 25% to cut down on power consumption.

Typical life for a lamp in that projector is:

3000 hours on Normal mode
6000 hours on Eco mode

You can expect a brightness loss of 50% when you are approaching end of a lamps life.

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.

Hi we have an infocus 4805 and had to store it (very carefully) for 5 months. Now when we come to use it there is a light for about 30 secs if you look down the lens and then nothing. The bulb had hours of...

After storage for a while one of the fans may be stuck causing the over heat safety circuit to shut down the projector. Use a bright flashlight & look in vented areas for fans & use a popsicle stick, thin plastic straw or suitable while unplugged (do not use anything metal) & give all the fans you see a little push to turn them around some. Also remove the lamp cover & remove the lamp & push the cooling fan inside the lamp compartment to loosen it up. Put the lamp back in & replace the cover & then plug it back in, wait 5 minutes then try starting it up again.
Just one of many things that can be wrong but worth a try. Good Luck,

Loud huming noise and vibrations from infocus x2 unit.

the berings on the colorwheel are failing. i suggest replacing it. also, the discoloration is baked-on dust. the wheel can be cleaned, but it's no recomended, due to the finish on the glass and the fact that the heat has probably weakened the glue holding the glass on the wheel. it's the same glue holding the light tunnel together, and it's collapse is probably causing the faint image. the parts aren't all that expensive, but you can only get them through an infocus authorized service center. check the website for one.

InFocus LP280 problem

Hi there

I'm afraid this might be a faulty Mainboard.

Your lamp will never make the Projector show funny stuff on the image.

Must warn you that a new Mainbaord is quite expensive

The bulb won't do that. What you're describing sounds like a light tunnel failure.

Most projector lamps last approximately one thousand hours. Other possiblity might be the filter that has darkened due to heat.
