Question about Mitsubishi WD-52631 52" Projection HDTV

1 Answer

Mitsubishi WD-52631 "Check airflow"

Our 52" 1080p Mitsubishi will occasionally shut itself off with an error message to "check if airflow is blocked". This is the most annoying thing as it may come right back on, or it may take a long time before it will stay on. It appears that the sensor for temperature is VERY sensitive. Anytime the ambient air temperature changes fro the heat kicking on or off, the TV wants to **** out. Is there any way I can bypass this sensor or decrease its sensitivity?

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.
