Question about InFocus LP70+ Multimedia Projector

1 Answer

In Focus LP 70+

I just replaced my lamp with a new one. The projector turns on and I get a solid green LCD light. The fan is also continuously running. I still have no picture. I have read that I need to reset the lamp timer. Since I do not have any image to look at it, how do I do it? Do you have any other ideas?

You might wanna try to reseat the lamp just to make its locked into place, if that doesnt work then contact the manufacturer or exchange the lamp from where you bought it

The projector turns on but won't project any light through the lens.


If this is a NEC VT series projector, Change the lamp. When if it continues to blink amber and not project and image after installing a new lamp check the lamp cover to see if the micro switch tab on the lamp cover broke off. Some models have a built in lens cover. If the cover is not slid over to open completely the light may not turn on.

In Focus LP 640 won't even turn on? Any help


There are several reasons this could happen, and can usually be identified by glancing at the Power LED. The following applies to this particular projector:

1) Blinking RED led- Lamp or fan failure. Usually this is a bulb issue and simply needs the lamp replaced and the lamp life hours reset. Below you will find an image from the owners manual that will allow you to translate the # of times the LED blinks into a problem/solutionrobertsager.png
2) Solid Red LED means unidentifiable error. You will need to contact customer support at that point to schedule service.

Projector shuts off within 30 seconds of power on


is the led lit on the top of the projector? what colors?

green is ok.

red flashing in sequence:
2 times- lamp hours exceed 200 hrs. replace lamp.
3 times- lamp failure. replace lamp.
4 times- fans not working. remove obstruction or replace fan.
5 times- temp too high. clean thoroughly.
solid red- undiagnosed error by projector. possible power supply or ballast.

also make sure the lamp door switch is working.

Optoma 719, can't get lamp and fan to turn on.


There is a stuffed 10v 3300uf capacitor on the power board. You need to replace it.
Bellow you can check in the picture where the capacitor is located.

Notice that in this picture I have already took the bad capacitor out and replaced with two small cords to reach the bottom and test the new capacitor.
To reach this place is not fast, several layers of plastic and metal must be removed, but is not a hard task to take the capacitor out and replace it for another.
It works just great! Now it is back on track with awesome image.

A couple of things...

If the fan is not working, the lamp will not fire. If you have the owner's manual, it should indicate what the flashing lights mean. Check to make sure that the panels are seated properly. When you replaced the lamp, the outer cover was removed. If that is not seated back 100%, the unit will not work. There are a number of safety "checks" built into the unit to prevent damage and possibly fire as the lamps get really hot.

Check the items above and let us know your progress.
