Question about InFocus LP 600 Multimedia Projector

5 Answers

Infocus mod.610/620 Lite pro

Unit runs fine for 15 to 30 minutes,then shuts down after a few minutes you can restart it and it works well for 15 to 30 minutes.
when it shuts down the light on the button is still on.It acts like it
just switches to the standby mode. Fan continues to run.
Any help appreciated.

  • bobbytrue Jun 27, 2008

    The room temp is 75 degrees ,I cannot find the filter

    I have tried all the fixes that have been suggested to no avail.I have cleaned it out

    blown it out,at least it went 25 minutes today before it quit.Is there some sort of high

    temp.switch thacpould be the problem?Upon removing the front panel,I saw a white ceramic looking device about three eights by one inch long with a wire connector on each end.When the main power switch is turned on,this device shows arcing internally.Then the lamp comes on.I thought it could be a fuse but when checked with an ohmmeter it shows open or very high resistance.Will someone explain if this is normal?Thanks,Bob

    One person states that once you change the bulb,you must reset some

    timer?Any more comments on this timer and how to reset it and where it is located.

    Thanks,Bob

  • bobbytrue Jul 11, 2008

    I do not understand SYSTEM TIMER.Is this to show hours of lamp usage>

    But this should not cause the shutdowns ,should it?

    Any more comments or solutions?

    Thanks Bob

    I checked on the system timer and there is a factory flyer stating that the model620 no longer had a timer and that the overusage light was discontinued.But the lamp usage counter still worked.I did reset the timer to zero just in case.The timer showed 378 hours.I am still very puzzled so if anyone has a suggestion,I will be happy to try it.

Hi,

Clear out any dust that might accumulating in the vents and anywhere that gets hot.

Dont move the projector when it warm though or you might damage the lamp.

You might need to take the projector apart to get to where it needs cleaning, take all precautions about electric shocks.

Hope this helps

Andy

Projector is overheating. Turn the projector off and let it cool for 30 minutes.
Clean the air filter and check all ventilation holes for blockage.

Hope that helps..........

It may be reaching its max temp and shutting down to avoid over heating or popping the bulb. How is the air ventiliation and room temperature? You may also want to browse through the settings or check for a switch on it, to make sure it isn't set to go into a stand-by mode after such a short period of time.

My infocus 1503 works however once it is turned on the unit sounds as though it is ready to take off. The fan is very loud then after a few minutes it quiets down and then the fan becomes very loud again....


I own two of these projectors. You need to update the firmware to 1.03 which can be found on the infocus website. This solves the fan issues which also causes premature shutdown of the projector. Once you download the update, open it, there will be step by step instructions on how to do this procedure. I could not get this to work with Vista 64 so you might need to run this on XP or 7.

After running for a few minutes it shuts off, won't restart until it cools down


the Projector unit may be overheating due to airflow. ensure that the intake filter is not blocked, remove and clean it and then replace do not run with filter removed as this will cause dust inside your machine. check that none of the airflow slits on the body of the machine are bloced or taped over.
check that the unit has enough airflow around it to keep cool if unsure move the machine to a open space and let it run to see if the problem persits or stops.

if this persists it may mean the overheat cut off switch is defective and keeps activating even though the machine is not overheated.

I hope this helps.

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.

Mitsubishi HC900 Projector shuts down after 5 minutes.


You have 1 of 2 possible problems.

(1) You need a new lamp.

(2) You have an overheating problem.

Just a quick couple of notes about your projector. It is a DLP projector (not LCD) and as such the machine as no air filters to clean. It does have air intake and air exhaust grilles, but no air filters to clean. This next part comes directly from the owner' manual for your projector:

When the lamp operation time exceeds 2000 hours*1 *2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp operation time is reset.

Your machine is designed to give visual warning messages at 1500 hours used, and 1900 hours used. Did you see any visual warning about lamp life over the past few months?

If you were experiencing an overheating problem, a "TEMPERATURE!!" message would flash up on the screen just before the unit shuts down. If there is no warning, you don't have a heat problem.

If you have a replacement lamp available, install it and reset the lmap hours according to your user manual. If you don't have the manual, google it on the web (it available).
