    Dell 3400 MP Projector temp light on

    I use Dell 3400MP Projector at my office. Today it surprised me with sudden shutdown with the "TEMP" light blinking orange. I thought it may be the cause of defective fan, but I can hear and feel the fan blowing on startup.but the temp light still blinks and it will turn itself off after few minutes. Why is that so? Do you all have any suggestions ?

    If you have a cooling fan it may not be running or dust may need blown out or possibly the thermistor which controls the fan has gone bad. If the TEMP light is solid orange, the projector has overheated. The display automatically shuts down. Turn the display on again after the projector cools down.

    If you see the TEMP light is blinking orange, This means a projector fan has failed and the projector will automatically shut down. If the problem persists, contact Dell.

    Do not attempt to replace the lamp until the projector has been allowed to cool down for at least 30 minutes.If you have a cooling fan it may not be running or dust may need blown out or possibly the thermistor which controls the fan has gone bad.

    I have a brand new 4310WX, and when I powered it up, the screen showed "fan fail" and it shut down. I contacted Dell tech and after having me go through steps to pull out the lamp and put it back, he's sending out a replacement projector.
    Needless to say, I'm very disappointed. This was a brand new projector.
