I haven't serviced an infocus projector before, But I have seen 3 or 4 Red cutting out display simptoms on projectors caused by bent or pushed in gold pins on the VGA leads. (it always seems to be red!) I won't comment on insides but do check this basic tip before delving in too deep. Good Luck

Infocus sp5000 red led blinks once indicating lamp


be sure and reset the lamp hours. Flash the software if you can. These are also notorious for the ballast cable on the inside of the lamp housing backing out when a lamp is removed or replaced. If you have the cover off push the cables back into place and hold them there as you install the lamp. Also look directely at your lamp in the center and move it side to side and up and down. If there are any cracks or frosty looking spots or bubbles in the mirror of the lamp that are visible, then the lamp is probably shot. If all this fails, most likely it is the power supply, or the lamp door has gotten mishapen from heat and the actuator on the lamp door isn't making full contact with the safety swith.

LP540 Projector Lamp Does Not come on> it has an error message; "Lamp didn't Strike". Does that mean the Lamp/Bulb is bad?


Hi,
It's most likely the lamp is bad or the part that starts the lamp called a ballast is bad. The LP540 model has an issue with the ballast burning out. The ballast is a part that starts or strikes the lamp. The only sure way to test is to try starting it with a known good lamp.
You can check for signs of a bad lamp. Think about how long you've had your projector & estimate the total hours on your lamp. If it's over 500 it very well could be the lamp as they fail at any time. Remove the lamp cover door & pull out the lamp to visually inspect it. Look in good light & use a magnifier if available too check for any cracks or chips in the small bulb & look to see if the round part of the small bulb is covered with a lot of white or if it's not round anymore. If it's very white it means it has a lot of hours on it. If there's any loose glass inside (check by turning the lamp cage in different directions) then the lamp is bad. If it's nice & clear or has only a small white spot it's probably a good lamp.
I repair almost all Infocus models if you need a quote.
Thanks & good luck,
Jim

Hi,
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,
Jim

there isn't one. you need to see the menu. but what color is the led and is it blinking?
green- all is well
red blinking:
1 time- lamp not striking after 5x.
2 times- lamp has more than 3000 hrs. replace lamp.
3 times- lamp failure. replace lamp.
4 times- fan failure. shuts down.
5 times- undiagnosed error. possibly ballast or colorwheel.

if the colorwheel won't spin, the lamp won't light. when you turn on the projector, do you hear a high-pitched whir? if not, the colorwheel needs replacing.

LP540 INFOCUS


good luck. not even the infocus authorized service centers get those. besides, they were made by another company that does not make power supplies antmore. and infocus doesn't have any new ones in stock. if you're getting no power at all, replace the mosfets. it works half of the time.
