Question about InFocus LP725 and LP735 Replacement Projector Lamp - SP-LAMP-LP7E Projector Lamp

InFocus LP725 light goes out after 10 minutes

Hi. I have an InFocus LP725 projector that works fine for 10 minutes into a presentation but then the light goes out. Let it cool down for awhile and it will light again.  Is there some type of thermal switch built into these that causes it to shut down when it gets too hot.  We bought a replacement lamp for it from a source other than InFocus and now I'm wondering if it might be a higher wattage than the original.  By the way, I did check the fan filter and it was clean, the fan works fine and is unobstructed.  Any suggestion would be appreciated!  Thanks Steve

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

i was thinking of a different model, but I'll be honest, if you are sure your lamp is good and ALL of the fans are on, then it probably is the power supply acting up again.

if you don't know exactly how many hours are on the new lamp, you can't be sure it works. since it's a mercury lamp, there will be no contenuity. check the lamp for cracks or clouding, not just burn marks.if the lamp is actually good, you may have a ballast issue.

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.

Black lines are appearing on the top and bottom of projection,.


try factory reset in the menu. if that doesn't help, it could be the light tunnel, but infocus doesn't have parts for the lp3xx series anymore.
