Infocus LP-820 no power

I have an LP-820 and nothing happens when I plug it in. I took the bulb out and it is blown, but shouldn't I see a light or hear a fan or something?

You should get some indication of power even without the globe. This can however be a problem relating to the globe not being inside the projector.
Most projectors use a switch inside so they know when a lamp is installed. Some have several of these and a fuse that is on the lamp unit itself.

Replace the lamp back into the projector and apply power again. If you get lights then you have that much solved at least.

If there are still no power lights at all, then you may have had a power surge that not only killed the globe, but has blown the internal fuse for the power supply as well (or even killed the power supply)
To get access to the power supply you will need to disassemble the whole unit almost. If your not comfortable doing this, then I would advise getting it checked over by your local tech. It could save you hundreds of dollars buying a new lamp when the projector may not be worth repairing.

Hi There... I have problem with my Infocus LP 130 The power is still ON, fan at the back is still working caused I can feel the air flow, but no light coming out from the lens. Can you please advise, what...


theres another fan next to the engine. all fans must work for the lamp to light. the colorwheel must be turning freely for the lamp to light. you can also take the top cover off and then slide the lamp out and then back in while watching to see if the connection on the lamp is pushing the female part on the lamp housing back instead of going into it. if it is, hold the female part in place with a driver or something while pushing the lamp into it.

Infocus lp820 i press power can not hear any fan moving lamp turn on with gray light after 10 sec lamp shut off and message says "fan stopped"


you need to replace the fans; they may have burned out. you could try to get one from an infocus service center or send it to them for repair, but know that this is an old machine and parts may not be available. you could try getting a used one on ebay that has a different problem and swap out the parts. if you do decide to send it in or find new parts, try av solutions in ny. they're really good. www.avsolutionsny.com

Infocus LP 280 runs for 1 min then shuts down, runs again then


are the leds on the top lit or blinking? it could be the lamp, the ballast, or the fans. check the lamp. if there are black spots or bulges in the lamp, replace it. if not, make sure the fans are running. if they are, replace the ballast.

Infocus LP530 no power


the power supply needs replacing. sometimes the caps are dried up, but show no signs of damage. when the caps doesn't work, the ps doesn't work.

LP 240 stopped working. No lights, no fans, nothing.


Please describe the status of the LED indicator. No LED would indicate a failure of the power supply. I can help you with that.
Flashing red would indicate a fan/lamp problem. Some lamps fail prematurely before the lamp hours are up.
If it is the power supply, no lights at all, I can get you running again. These units have fragile power supplies that can burn out with the slightest power surge. A UPS goes a long way to save future headaches.
