PJD 5111 Viewsonic projector shuts down after 10minutes?


Hi! I think it is the time to remove the cover and check for air filters blocked with dust.

When this happens, air doesn't flow freely through the projector and result in overheating, which leads to automatic shutdown.

Boxlight CD-725C TEMP light comes on and unit shuts down afer 10 minutes. Unit has about 1200 hours on the bulb. Seconds before the unit stops, at least one of the fans slows down.


The reason why the temp comes on because the fan is start slow down, so the bulb produce a lot of heat. Once the maximum temp reach, the temperature sensor will become inactive. So boxlight shutdown. First you need to replace the fan, or check the supply dc voltage going to fan if it is stable.

ASK M3 shutdown


if the fans are running too slow, it'll shut down. it needs the fans to run at a certain speed to get enough cfms to ensure proper cooldown. if one is lagging, the lamp or power supply may not cool enough and cause damage. find out which one.

Auto shutdown sharp xg-p25x projector


This would seem to be heat-related as these lamps get hot rather quickly. The first quick and dirty solution - try cleaning the filter which is under a panel on the bottom of the projector. Another fix - be sure the projector is plugged into an image source; i.e. computer or DVD player. Sometimes these units will go into standby mode without a signal. More difficult fix - be sure the fan is runningn. When it shuts down, the fan should keep running until the lamp cools, then it will shut down. If the fan isn't working the temperature build-up with shut the projector off. Replacing the fan may be a job for a tech.

VPL-HS20 shuts down in the middle of a movie


There is a heat sensor cutting down the power. The sensor is located on the upper side between lamp and fan and is monitoring the air temperatur. I don't know what is causing the sensor to switch - excessive heat or simply age or ... . Anyway un screwed this sensor and my problem disappeared.
Possibly a stronger fan would solve the problem too.

ALSO CHECK YOUR FAN. IF THE FAN OR A HEAT SINK IS NOT WORKING PROPERLY (I.E. THE FAN MAY JUST NEED TO BE CLEANED OR REPLACED, THERE SHOULD BE A SMALL HEAT SINK. IF CLOUDED W/DUST, IT WILL KEEP THE OPERATION SHORT). ALSO CHECK IF YOU HAVE SET ANY TEMPERATURE SHUTDOWN PARAMETERS. IF YOUR LAMP HEATS UP FOR SO LONG AND REACHES A TEMPERATURE THAT WILL AFFECT THE CIRCUITS, THIS OF COURSE WILL SHUT DOWN YOUR UNIT UNEXPECTEDLY. HOPE THIS HELPS...JGUAM
