Air flow blocked...turning off in a few seconds message

Use Osram or Phillips bulbs

Check for blocked air flow

Always allow TV to complete cool down with plug in wall

Check/Replace ballast

Check the fans are free and running. If a fan has stopped that message will be produced.
Hope that helps.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.Have a bless one!

Replacing the thermal sensor is the cure for this. If you call Mitsubishi at 1-800-332-2119, press 5 for Customer Service. Explain the problem and they will probably approve a extended warranty claim and get the repair done for free through a Mitsubishi Auth. Repair Facility. They will also help get you in touch with one near you. Do not delay in acting on this. I do not know how long the extended warranty claims for this problem will last.
Hope this helps,

let it start up you will here things happening, engine will start first then a buzz to start the lamp if you here all of this you have a bad lamp.You should have a error code let the tv try to start leave it alone and see if you have an error. As soon as you reset the tv you loose the error.

If the set is only 3 1/2 months old, you should still have warranty coverage. Opening up the unit will void the warranty, so don't open up the set. Call for warranty service. In all probability, the air flow sensor is defective. The message you are seeing is a result of the air flow not being detected or not sufficient. In any case, this is a covered problem and should cost you nothing to fix.

Hello!! It might be either that the tv is overheating because of the lack of air, or it may also be your ballast.
First of all I recommend you clean the fans, so the air flow won't be blocked, don't use something that mioght damage some of the boards that are inside, you can buy one of those air cans to clean computers, if that does not work, I recommend you listen closely and notice if there's a clicking sound, if so it might be the ballast.

unplug all nite.

have you cleaned the air filter located on the side of the set? If that doesnt work the thermal sensor will need replacing.
