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.

How can you diagnose a failed lamp in a Mitsubishi DLP WD 52631


Remove the lamp and do a visual inspection.
If this is a DLP you may have a bad color wheel! whistling sound is a sign of color wheel.

Good luck to you

Message that TV is powering down, check air flow for obstruction


Mitsubishi has had some problems with these sets with the lamp cartridge(google the model number and look for how to replace lamp instructions) On some of the lamp cartridges they covered several openings with a fine screen like material---one is narrow and completely blocks up with dust---this will trigger the air flow message--if you get the lamp out and this screen is blocked, carefully clean the dirt off with a brush---if you don't get it soon enough it will kill the lamp----the replacement lamps for these sets use a bigger mesh that does not block with dirt---it blocks because there is a fan the pulls air and dirt into the set to cool the lamp during operation.


NEVER TOUCH THE FRONT GLASS OF THE LAMP WITH YOUR HAND

I do this here for free so if this helps you give me a vote here.
