I want to test my infocus lamp to know if it is burnt

I checked it for resistance, and no reading on my VOM. There is absolutely nothing when I turn my infocus sp7200 on.. No light, no fan, no led sign...nothing.. Could it be because the lamp is dead???

Your lamp might be ok, but you power supply is dead. If your not seeing any led lights come on when the power cord is plugged in then your power supply is dead. I can fix this for you for less then it cost to send to infocus or to a repair shop. Ebay Id is Gtitubro

2001 Alero, Blower worked on high only and then died. Replaced the resister. Started it up and everything seamed to work. Came out the next day and had to jump the car. The blower didn't work at all....

Are you sure the HVAC controls are funtioning properly? You should use a test lamp, buzz box, or a VOM (VOLT OHM METER) to test those controls along with the blower motor resistor, blower relay and the blower itself. This will take you all of 4 to 5 hours if you are a backyard mechanic. I will tell you this-power from all of the blower settings on your HVAC control in your dash does end up going thru a relay. This also could be what mechanics call an intermittent. You also need to know some basics about the wiring in automobiles.

My InFocus for the classroom won't even turn on. Absolutely nothing is turning on even though it is all plugged in correctly.

Either the power input board is bad,the fuse on the opwer supply/ballast is blown or the lamp door is not secure. This will have to be repaired by a tech if is either of the first two.

What does a lamp bulb look like when it is no longer good or working? does it look burnt out? Mine looks like nothing it broken or burnt, but my projector isn't showing a picture on the screen. the fan...

look at the lamp head on. an obviously bad lamp will have cracks in the mirror, the stem can have frosty,veiny looking blisters or bubbles, the mirror can have lots of bubbles. And sometimes there are just no obvious signs.

My infocus IN1 projector won't turn on anymore.

It may be the lamp is out. Normally a projector will try & fire the lamp 3-5 times then shut down with a different color light like amber or red. If the lamp doesn't light then it could be the lamp or perhaps the lamp ballast that starts the lamp has failed. A stuck fan also causes similar symptoms. There's 2-4 fans in the projector if one is stuck or bad it will turn off within 5 seconds or so after the lamp lights.
Does your lamp light at all? Are the lights a different color after it shuts down? Answers to these questions help figure out what's wrong though it's impossible to say for sure without looking at it. I service almost all Infocus projectors if you would like a quote please reply with your email address or write me at
Good Luck,

Infocus LP280

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".

Usually when the lamp is good and you get this message, the ballast is bad. That is the part thatdrives the lamp. Check with Infocus for a repalacement balast.

Infocus LP725 projector

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
