"Overheating warning" Everytime I turn the tv on a warning displays that says "TV will shut off soon, check if airvent if covered". The air vent isn't covered. What could be causing this? Can i spray some of that compressed air in the air vent and clear it out? I recently moved it a couple miles but I had it covered with a blanket and I was very careful. Let me know what ya think.

Hello

Put your hand on the back of your TV to check for overheating, if your set keeps switching itself off without warning.

Many TV sets come equipped with a safety feature that switches the power off if the set gets too warm.

Check the cooling vents located at the rear of your unit. Vents can collect dust and dirt, resulting in the fans becoming blocked and failing to work properly.

Remove dirt from the vents with a damp, clean cloth. Ensure the air conditioning is kept at adequate levels in the room where your TV is located. Keep the drapes shut on hot, sunny days to keep the room cooler.

Check the sleep-timer function on your TV if it keeps turning off. A sleep-timer is used to turn a television set off after a certain period of time has elapsed. If the sleep-timer is not turned off, your television will continue to turn itself off after a certain period of time.

If the problem persists,then a heat sink has gone bad.

The on/off button simply toggles a low voltage circuit that powers your tv. If it is dusty, it may complete the electrical circuit and send a false signal.

Take a can of compressed air, open the back and clean the dust off the circuit boards.

NOTE;opening the TV VOIDS warranty!!

This could be caused by poor ventilation on the unit. The back of TV sets where the air vents are usually located are meant to be easily accessible to air. When they do not have enough air then the Tv tends to shut itself down due to overheating when it geths too hot.
Try relocating the TV position to an airy environment.

Make sure that you clean out all vent holes behind set. My own dlp has shut off from poor air circulation due to dust and debris in the air. The cooling fans must have good circulation or the set has tempurature sensors to shut it off. Use a brush or vacuum on all the small vent holes around the set. Also, alot of these sets have filters that clog up. Check the owner's manual or look for a small door where a filter could be around the base of the unit. If this doesn't solve the problem you need a service person to check it out for you. Good luck, Russmann.

You probably have a bad thermal sensor.

check all the fans and make sure they are clean and not plugged up w/dust.also check how many times the red light flashes on the front of the tv after shutting down.4 flashes indicates a bad fan.

if your computer is randomly keeps on shutting down this is a thermal issue which you need to address. check airvents, use compressed air to clean all possible obstructions between heatsink fan and processor. try avoiding blocking the airvent of your notebook. try also updating your bios

contact mitsubishi customer relation at (800)332-2119..there is a service bulletin on this problem and mitsubishi has extended the warranty for repairing this problem for 2 years

From my experience of Studios it's also a possibility that the TV is overheating. Check that any vents are not covered and that there is enough airflow around the TV. Sounds like a thermal cutout is triggering.
