Question about InFocus Projector Lamp for IN24+, IN26+
Being I accidently bought an IN24 lamp for a IN24+ projector and opened the box, thus elimating my chances of exchanging it, I want to know if the operating voltage is the same for the IN24 and IN24+ lamps. I realize and can deal with that the IN24+ is a high wattage lamp and is wired differently.
SOURCE: Lamp resistance and voltage
1. Projector lamps use customized ballasts that ignite the lamp
by charging it with a higher voltage in the ignition phase and then
dropping down to a lower running voltage once the circuit is created.
2. Projector lamps CANNOT be tested with an AMP or OHM meter. Projector lamps function by igniting ultra-high pressurized mercury vapor across an ARC tube. At the point where the mercury vapor resides there is no conductive electrical material and therefore testing a projector lamp with an AMP or OHM will not work.

more then likely the ballast has gone bad and the lamp is not getting the right voltage to fire. Only other thing you can do is remove the lamp the turn the power on and check the voltage at the connector. This will not check the triggering voltage mine you only the lower operating voltage. But since you have replace the bulb with a known good one I'm betting on the ballast is bad.

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,
