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.

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

InFocus LP540 Power Supply Problem

most of infocus parts are oem and made by a company in taiwan that no longer makes power supplies, and many of the parts have their stock numbers and not neccesarily a common stock. the power supply, however, is in stock at infocus for about $65.

Infocus LP540

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 LP540 --- display

It sounds like you may be feeding it with an HDMI source using an HDMI to M1-D adapter...

If this is the case, make sure the source in not set to a resolution higher than 720p.
However I really need more information to offer a definitive solution.

Take Care!

Check for internal fuse on power module, you will have to open the case.
Make sure power cord is removed. Be carefull capacitors tend to hold a charge long after power is removed. I have a LP640 ....big brother to this one. If you open the case the warranty is voided so think about it first. the fuse could be on the circuit board and will look like a small solid green resistor or it could be a full sized fuse in-line with the wires coming from the power cord connector. I have seen the inside of a LP390 with the fuse behind the power inlet connector. Good Luck
