EXTRA fan for cooling lamp and tv location

05-22-2010, 09:43 PM
Hello and good day! I have a Mitsubishi WD-73734 DLP. I love the tv and true to form it goes through a bulb about every 4500 hours. Such is the price for a big beautiful picture for reasonable price..
I have looked for the info in the owners manual and have not found any information, as well have looked for a service manual and have not found one.(side question: anyone know where I can get one of those?)

So.. I have tried to determine where the intake vent or path is for the lamp and electronics area of the set using a lit match and have only been able to determine that air flows out of the lamp assembly grill and the grill above it.. ..
Can anyone tell me where the intake vent or opening is located? I want to set a small 6" fan behind the television to assist in cooling the lamp and to help extend the electronics life as well. Does anyone know where the best spot to put an extra fan is?
Should I simply place the fan and suck the air out of the vents/grills at the Lamp Door and Grill area above it?

Thank you for your time and help!!

If your set is like my 65" mitsubishi, the lamp cooling fan exhausts directly via the duct you mentioned and cooling air is drawn through the entire vented rear panel through a screen filter on the lamp assembly and then out the duct. Keeping the lamp assembly screen clean is foremost in importance, and you can access it by pulling the lamp assembly out.
I have a small fan that circulates air to the rear of the set, as the tv is close to the wall and stagnant air can build up. Have no idea if this helps or not. My set has the 180 watt lamp, same as the 73".
I believe proper cooling of the lamp is very important to its life!
