Airflow blocked tv will shut down after a few seconds
Greetings: I saw that you addressed this issue before by suggesting checking the lamp thermal sensor. I am having the same problem... the fan under the runs, there are no blockages of the air flow, I have unplugged and plugged back in (ensuring the connection was solid) How can I test the thermal sensor? I am assuming that it is a bit more complex than a simple normally closed switch.
Any assistance would be welcomed.

Re: airflow blocked tv will shut down after a few seconds
If you have a WD-52525 Model TV and the the screen displays "air flow problem" change the sensor. There's not a positive way to check device, just replace it, trust me. IF your TV is a different Model MIT'S has a recall on those certain Models. REPLACE.

Well....the reason you are getting an "airflow message" is that there is a thermal sensor on the BACK of the lamp cage, and the connections on it get to be "intermittent" after awhile...and when this happens...the computer thinks that the lamp is overheating due to a dirty filter or fan--and shuts down the set.
It is a small, white plastic sensor, with 2 wires on it, that go to a connector and it has a black and red wire(usually) in a twisted pair that connects to the sensor connector. The connectors need to be REMOVED and the sensor HARD-WIRED (directly connected to) the other pair of wires. IF you have done some electrical work before...this is easy. You only need about 3" of spare wire to patch in between the sensor and the other connector, after you cut the connectors off. BUT...if you do NOT have repair experience...I suggest you call a COMPETENT, FAIR tv shop in your area, if you do not have a service plan...and tell them you have a mits. set that needs the "airflow sensor problem" repaired . this CAN be done -in-home, in about an hour or less, and for under 300, including service call.
It sounds like you have a thermal issue. The TV is getting too hot or the Thermal Fuse is bad. The thermal fuse detects the temperature in the TV and tells the TV to shut down if it thinks it is too hot. Most likely caused by poor ventilation or clogged fans from household dust. Try moving TV away from wall or cabinet first, if this does not fix the problem, clean ALL the fans in the TV. If problem still persists, replace the thermal fuse.
thermal sensor problem.... there is a service bulliteen to service shops about this.. this generally a warranty item that is covered.... you will have to get a tech to see if its covered. the thermal sensor needs replaces.not to difficult to replaced
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
