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 IN10 projector, when I turn it on the light blinks green for a while (with no picture) and then it shuts off and blinks red (more than 5 blinks)


if Lamp or projector shuts off after running a short period of time, This is usually a thermal issue caused by excessively
high internal temperature. The high temperature
could cause a component on the controller ECA or
the power supply to fail when it gets hot.
First you need to check the fan operation, Are 3 fans, two for lamp and one for the color wheel. Check the elevation foot, if something is broke maybe something stop the fan.
Remove the lamp module.
Examine the fan assembly through the recess in the bottom case. Plug the projector in and turn it
on. Both fans in the fan assembly should start up and run for 5 - 10 seconds, then shut down
(because there is no lamp installed). This is time enough to make sure the fans work properly.
Make the same for the color wheel fan, you need to remove the top case.

I have an infocus lp820 with what looks like an blue ghost omage in centre of screen,i suspect optical engine or lcd panels


This projector is one I've worked on many times and you are correct. The lcd panels are burnt probably due to a hard shutdown not allowing the fans to cool the inner components done repeatedly over several sessions.

Can't start infocus sp7200 after changing lamp.


The end of lamp timer has reached it's limit and won't let the new lamp strike. What you need to do is Reset the end of life timer. To do this, with the projector switched off press and hold both the up and down Brightness buttons on the projector. while holding them in turn on the projector. Continue holding the buttons in for 10 to 15 seconds This will reset the end of life timer in the projector.


Cheers

My infocus IN1 projector won't turn on anymore.


Hi,
It may be the lamp is out. Normally a projector will try & fire the lamp 3-5 times then shut down with a different color light like amber or red. If the lamp doesn't light then it could be the lamp or perhaps the lamp ballast that starts the lamp has failed. A stuck fan also causes similar symptoms. There's 2-4 fans in the projector if one is stuck or bad it will turn off within 5 seconds or so after the lamp lights.
Does your lamp light at all? Are the lights a different color after it shuts down? Answers to these questions help figure out what's wrong though it's impossible to say for sure without looking at it. I service almost all Infocus projectors if you would like a quote please reply with your email address or write me at prmhelp@earthlink.net
Good Luck,
Jim

Infocus LP820 - Turns on for 30sec then shuts down


This could be one of two problems I have seen with another model Infocus projector (they are very good projectors though)

The first is the video input. Make sure it is attached correctly at both ends of the cable.
The second, remove the dust covers and blow them out. The problem can arrise if the temperature sensor detects the air inside the unit is getting too hot. If you can see the sensor when the dust covers are off (it will look like a little lump of goo on the end of a wire) then just give it a wipe as well. If dust settles on those it can cause incorrect temps to be reported.

Hope that solves your poblem =)

InFocus LP725 light goes out after 10 minutes


The Projector will turn off after so many hours of running the same bulb module. The counter will turn on a replace bulb LED. Installing the new bulb module should reset the counter and turn off the LED.

Check the projector’s lamp to ensure that it is securely connected
in the lamp module. Make sure by removing it and reinserting it.

Check the cables for problems.

When testing, power up in this order. Projector, Computer monitor, Computer.

A minor power surge may cause the lamp to shut off. Turn the
projector off, wait at least 30 seconds, then turn it back on.

I hope these suggestions help

Tv keeps turning off?


cutta, you will most often hear a click on boot then the fans start up and lamp will then fire. The picture will start to show up....at what point does it shut off? and do you hear a click when the tv is turning off? Is it the complete tv shutting down, fans and everything that turns off? Do you see any lights on the the front panel "POWER", "STATUS" or "LAMP", what are they doing? If you see a Power, Status or Lamp light after it shuts off the below are what they mean if there is an issue. POWER - STATUS - LAMP - CONDITION/ISSUE: Off - Yellow - Off - Temp. high/dirty filter/excess room temp Off - Off - Yellow - 4000 hrs. Lamp usage warning Off - Off - Blink Yellow - Lamp Cover open Off - Blink Yellow - Off - Air Filter Cover open Off - Off - Red - Lamp failure (failed to turn On or broken) Off - Blink Red - Off - Fan Has Stopped Off - Red - Off - Circuit failure (short) or DVI cable disconnected If you want to check for the last "Error Code", after you first turn the TV on, by pressing the front panel ?DEVICE? and ?MENU? buttons at the same time and holding them for 5 seconds, it activates the Error Code Mode. The ?Power LED Light? blinks/flashes (1/2 sec delay) and then flashes again denoting a two digit Error Code indicating no problem or an error has occured since the last Initalization. i.e. "Power light" blinks 3 times (1/2 second delay) and then blinks 4 times then 1 sec delay and repeats a few times. This would mean "Error 34 - Lamp abnormality". See below for error codes..... Error Code - Description or issue 12 - No Error detected, check Power Supply 32 - Lamp Cover is open 33 - Air Filter Cover is open 34 - Lamp abnormality 36 - Light Engine (DMD or LAMP Fan stopped) 37 - Exhaust or Lamp Ballast Fan stopped 38 - Lamp temperature high 39 - DMD temperature high 41 - Short is detected 44 - DVI cable between FMT & Engine disconnected. Sorry for the long answer but it was an open ended question.

Problem with INfocus LP425z Colorwheel ?????


That unit has a bearing color wheel, if it was not stored proper, it could be sticking. That would explain the power cycling. giving it a bump start if you will. Yes you can open and inspect to see if color wheel "free wheels"
