"Please check if the air flow is blocked."
"...A limited number of DLP Projection Televisions are displaying a false message, "TV will shut down in a few seconds. Please check if the air flow is blocked," and then the TV shuts off." is what Mitsubishi Digital Electronic America (MDEA), a subsidiary of Mitsubishi Electric, started acknowledging in 2008-2009 even though complaints about affected TVs apparently started in 2006! What took them so long?
Models affected by this issue are DLP Projection TVs WD-52631, WD-57731, WD-65731, WD-Y57, WD-Y65, WD-57732, WD-65732, WD-57831, WD-65831. Mitsubishi attributes this to a loose connection defect and mentions covering the cost of the thermal sensor (parts and labor) at no charge and extending the warranty by 2 years
