3M SCP712 projector shuts down after an hour--can't turn back till it cools


Hello
the problem is with overheating. Look whether the cooling fan doesn't work or air filter is cloggy with dust. OK.

Sanyo plc-sw30 i have a problem when i power on the projector , there is no power lamp on a very slow light is visible and the projector shut down and the fan are in very high power


The uProcessor thinks that it has overheated and is frantically trying to cool down what it thinks is a hot lamp.
This condition has many causes from an exhausted lamp to lamp ballast fault or even a power supply fault or a heat sensor/fan fault.

Projector turns on for about 30 seconds then shuts down. the fan kicks up high, and led light flashes yellow for about 4 min until the fan shuts off. does not feel hot so overheating does not seem to be...


if the lamp lights and then shuts down, replace the lamp. it's at the end of it's life. to rule out overheating, blow the projector out with canned air. dust retains the heat that the projector is trying to expell. also see if all of the fans are working. if you do get an image for a short time, try to get into the menu to reset the settings to factory default. lastly, if all else fails, you have a ballast issue. unfortunately, infocus no longer sells parts for this model.

Lamp will not stay on more that a minute or so. Why? All of the fans are working and none of the vents are clogged but it is like a thermal switch shuts the lamp off.


if the projector is overheating, it will shut down. blow out the projector with canned air. the dust keeps in the heat that the fans are trying to expell. if it has shut down from heat to often, you'll need to replace the thermosensor. if you are not sure it's temp related, check the lamp for bulges and black spots. replace lamp if necessary.

Our PJ-TX10 projector is turning itself off


First, to rule out true overheating, clean any dust filters and air-access areas. There might be enough dust on the filter to cause a gradual build-up of heat which could trip one of the temperature sensors in the unit. I clean my projector once a week--There might be a cooling fan going bad--after a while, heat causes the fan motor to start to drag and slows down the air flow. Also, there might be a temp sensor that is shutting down the unit prematurely.--Rick

The projector is starting up but after warming up it shuts itself off. It is not the a problem with the filter, lamp seating or an overheating issue.


Does the lamp actually light up and project? If not, it's probably a dead bulb. Are there any flashing lights that might be displaying an error code? How dow you know it's not overheating? Remove the filter and give it a good cleaning. Some projectors measure airflow and, even though the heat hasn't built up, the projector shuts down because it predicts overheating will occur due to insufficient airflow.

Viewsonic PJ556d shuts down after 30-60 seconds


My solution sounds dumb, I had the same issue. Took the lamp cover off the bottom. The screws were loose holding in the lamp. Maybe they heat and expand and eventually work their way out and the lamp doesn't make good contact. Just tightened mine up, the unit would power off after 45 minutes prior. Been on now for 5 hours, no trouble.

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
