Error message airflow blocked tv will shut down after a few seconds model # 52530

you need a new power supply unit these after some time get old and start over heating causing the tv to heat up intermediately if you take it to a repair shop and have that replaced it will be like new again

YOU NEED TO REPLACE THE THERMOSTAT ON YOUR SET TO CORRECT THIS ISSUE .

CK your Fans make sure they are not dirty.

these are on mitsubishi's recall list you need to get in touch with mitsubishi and have them find a authorized servicer in your area to come put a thermal sensor in your set.

It is probably a bad temp sensor inside the TV. My 73" started shutting down before it was a year old. I moved it way out from the wall and it got a little better. A tech was just out to change the bulb under an extended warranty and he said there is a service bulletin about the temp sensor. If your TV is out of warranty you might call Mits and see if they will cover the sensor replacement. Tech said it takes about a 1/2 hour in the home to change it...

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.

The repair is to have the DLP engine replaced!!
FYI: The engine also can cause the set to shut down without any display or might even tell you the lamp door is open when it is not.

mitsubish has issued a service bullietin about the problem. which means ussally they will pay for its repair. the reson it says airflow bock is that there is a temperture sensor that is at fault... it needs replaced.

. Set shuts off after displaying the message "TV will shut down in a few seconds. Please check if the air flow is blocked." After shutdown, it may have a yellow status LED, self diagnostics indicates error code 38. To repair, replace the Lamp Thermal Sensor with the new version, part # 299P313010A. The sensor is located on the Lamp Cartridge Housing. See Service Tip VS-72B. Under rare circumstances, when a replacement thermal sensor is not available, refer to the original Service Tip, VS-72 (page 2 and 3 of VS-72B) If error 3-4 then this maybe problem:. Check to see if the lamp is on when the unit is off (in standby) if it is components on the Power PWB... K9A20 and/or K9A21 are shorted. Also, R9A02 may be open. Possible side effects ... deformed lamp exhaust duct and damaged lamp. Replace PWB-POWER part # 934C228003 and if necessary, Lamp part # 915P049010, Lamp Exhaust Duct part # 642B155010, and/or Lamp Exhaust Duct Cover part # 642B156010. See Service Tip VS-73 2. If the lamp never lights suspect the Lamp part # 915P049010
