Question about Mitsubishi WD-52327 52" Rear Projection HDTV-Ready Television

Air flow blocked message appears when turning on

I just started having the same problem with my Mitsubishi 52' DLP. i've had it for 3 years without any problems and just recently when I turn it on, a message at the bottom of the screen reads "check air flow to make sure it is not blocked, t.v will shut down in a few seconds. After I shut it down and turn it on the 3rd time, the message does not appear and the t.v works fine. Any other suggestions besides replacing the lamp thermoster?

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,

Air flow vent is blocked, tv keeps shutting down, mitsubishi ws-55615, how to fix ?


Mitsubishi's product line includes a wide array of LCD, Flat Panel, and DLP televisions to suit your home entertainment needs. The electronics division has the distinction of inventing the first rear-projection television and selling the very first HDTV in America. Their 400,000 square foot manufacturing facility, located in Irvine, CA, boasts the ability to produce more than 1,000 projection TV's in one day. The company's oft-stated goal of unmatched excellence is driven by their mantra: "Technically, anything is possible." In June, 2008, Mitsubishi introduced a new premium flat panel TV with an integrated 16-speaker sound projector.
Warranty Information
There is in-home service on all big screen models, which have warranties of 30 days for screens and one year for parts and labor. The LCD televisions have a one year warranty on parts and one year on labor with carry-in service. For plasma sets, in-home service is available on all models. There is a one year warranty on parts and one year on labor. The faulty thermal sensor, mentioned in the commmon repairs section, is now covered by an extended 2 year warranty, as is the problem related to the optical engine.
Common Repairs
For the following models: WD-52631, WD-57731, WD-65731, WD-Y57, WD-Y65, WD-57732, WD-65732, WD-57831, WD-65831, the most common repair problem stems from television shutting off almost immediately after it has been turned on accompanied by the message, "TV will shut down in a few seconds. Please check if the air flow is blocked." According to the Mitsubishi website, this issue is caused by a loose connection as a result of a faulty thermal sensor. For models: WD-73727, WD-73827, WD-73927, WD-73732, WD-7383, the most encountered repair problem has been in relation to the optical engine. Another common situation consumers have encountered is failure of the TV to turn on along with unceasing flashing of the green power light. The solution for this problem, caused by the DM board, will vary by repairman. Consumers have also encountered issues with moving vertical or horizontal lines appearing on the screen which can either be due to problems with the capacitor, light engine, or formatter board.

Air flow problem


Pull Lamp Out and see if when you try to turn it on if the Ballast Board has a spark/arking noise coming from it? If So Replace the Lamp.

My 52" dlp 1080P says check airflow and turns off. In same location for two years no dust bunnies air flow seems good, what can i do


That is a tricky sympton for that model . You'd expect it to only be prduced by the lamp temp sensor but the chassis fan stopping while tv is on can also produce that message on that model. I'd reccomend taking it to a repair facility . The chassis fan is the fan you can just see the edge/top of on the left side above the input jacks (looking at the back of the set with the back and the inner metal back removed). Other devices could possibly produce that mesage ,that model has 5 fans inside it! Temp sensors too.

most rear projectors will turn themselves off whenever the lamp is dead. what we call protective mode. in this case the yellow light may be for the lamp. otherwise check if all the fan are working properly.

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.

I have a Mitsubishi DLP 1080p TV with air flow problems


Hello ags98,

First I would suggest that you re-seat the bulb and then check the cooling fan, and air flow path. In addition to checking the fan make sure all air flow ingress and egress vent are unobstructed.

I hope this helps

Thank you,
