Question about InFocus SP-LAMP-017 Projector Lamp for LP540, LP640, C16

2 Answers

LP 540 Every time I start my LP540 it will run for 3-5 seconds and then shut down. The display will read "Retrying...." and it will come on for another 3-5 seconds and then it will keep cycling this way. Why does this happen?

Re: LP 540

1. Have you recently changed a lamp and if so, Did you reset the lamp timer and is your filter (if it has one) clean?
2. can you hear a FAN start when you turn the unit on?

Shut down after 30 seconds

Many projectors shut down if they cannot find anything attached to them.
Make sure you have a computer attached and sending an image out to it before you hit the projector reset button again.
It's a bit like the chicken and the egg since some laptops won't send an image out the cable unless it senses a projector, and the projector shuts down if it does not detect an incoming signal fast enough.

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,

I have infocus sp5000 and the lamp has stopped working. I pulled it our of the unit and it looks perfect. I suspect it is the lamp counter, but I need a method to reset without being able to see the...

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.

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!

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.
