Question about InFocus Lamp Projector Lamp for LP240 [ SP-LAMP-005

Infocus LP280 Shuts down

This projector will run for a half hour and then shut down. After it cools, the cycle can be repeated. All the fans are working up to the point that it shuts down. When I take the cover off and start it up, it runs forever. I am thinking that either the thermal switch is bad or the fan motors are old and not pushing much air. Could someone please shed some light?

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

Not mine but a friend's. Found a manual online, read it, fixed it. One must wait a while when pushing those buttons. One must have patience and read the manual before crying "it don't work".

I have an infocus lp820 with what looks like an blue ghost omage in centre of screen,i suspect optical engine or lcd panels


This projector is one I've worked on many times and you are correct. The lcd panels are burnt probably due to a hard shutdown not allowing the fans to cool the inner components done repeatedly over several sessions.

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...


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

I would replace the fans with a higher CFM fan. You can google the size fan you have and something should pop up. The stock fans are about 20CFM. You can get fans with over double that for about $5. Let us know if it works!

InFocus LP130 Projector has intermittent power off


go into the menu to find out the lamp hours. it could be the lamp, but if the projector shuts down and not just the lamp, there is either an overheating issue, or a power supply issue.

You may be hearing the color wheel turning. Make sure the lamp is installed correctly and lamp access door/plate is properly closed.

InFocus LP725 light goes out after 10 minutes


The Projector will turn off after so many hours of running the same bulb module. The counter will turn on a replace bulb LED. Installing the new bulb module should reset the counter and turn off the LED.

Check the projector’s lamp to ensure that it is securely connected
in the lamp module. Make sure by removing it and reinserting it.

Check the cables for problems.

When testing, power up in this order. Projector, Computer monitor, Computer.

A minor power surge may cause the lamp to shut off. Turn the
projector off, wait at least 30 seconds, then turn it back on.

I hope these suggestions help
