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


Hi,
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,
Jim

there isn't one. you need to see the menu. but what color is the led and is it blinking?
green- all is well
red blinking:
1 time- lamp not striking after 5x.
2 times- lamp has more than 3000 hrs. replace lamp.
3 times- lamp failure. replace lamp.
4 times- fan failure. shuts down.
5 times- undiagnosed error. possibly ballast or colorwheel.

if the colorwheel won't spin, the lamp won't light. when you turn on the projector, do you hear a high-pitched whir? if not, the colorwheel needs replacing.

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 --- display


Hello,
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!

LP540 Infocus PRojector


first try a new vga cable. if the problem persists, go into the menu and find the settings to that computer output. chances are it's on component. set it to vga. if that doesn't help, reset back to factory default, then set it to vga.

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.
