Fan down bulb overheating - Mitsubishi EX240U Projector

Probably the fan isn't working or is dirty and needs cleaning. The projector bulb is overheating and shutting down the TV. Clean or replace the fan.

This probably the fan is not cooling down the temperature of the high intensity bulb. Due to overheating the bulb will shutdown. Get a correct specification fan to replace the aging fan.

it's not recomended to run constant for a day or longer. it may have overheated the lamp. especially if you've never cleaned it out before. take canned air and blow out any dust. but first remove the lamp and see if there is dust blocking the side vent. if there is a lot, the lamp overheated and prematurely blew.

Get a small but powerful used computer fan and place it in the TV to replace the defective old fan.That's the best way.The factory fans in these TVs don't last.

the bulb may have burst from overheating from a fan not working to cool it down. and it can be replaced. it does take, however, a while to replace it because you have to take half of it apart. but make sure it's the fan first. take the lamp door off and remove the lamp. use something small and thin to push in the switch that the lamp door usually activates. turn the projector on and see if the lamp fan and the colorwheel (the multicolor glass disk) are spinning. if the fan spins, the noise may be from the colorwheel motor going bad. the fan can be purchased through an infocus authorized service center. check the website for the closest one. but the colorwheel for the x1 cannot be purchased seperately from the optical engine, and that costs a fortune. but here is the part number for the 80mm fan- 526-0152-00.

Sent me the serial number, and I can check for any re-call ...

the lamp is good for 2000 hours. it may shut down due to fan obstructions, overheating, or the colorwheel is bad and needs replacing. also, the power supply/ballast may need replacing.

Sounds like you have an overheating problem. Maybe a bad fan? Also you may have a bad connection to the "bulb".

Set the lamp to economy mode, make sure it is being used in a cool room with easy air flow thru the projector. If the problem persists, there are two fans inside and a thermistor that takes the temp reading, there is small adjustment POT on the board to increase the operating temp if needed.

I have a HP VP6111 projector that works fine on a table top but overheats ( overheating ) when turned upside down and hung from my ceiling. My solution...I went to Circuit City and bought two 80mm computer fans. I also purchased a 12V power supply from Radio Shack. I put one fan on front of my projector and the other on the back of the projector and wired them into the 12V power supply. I mounted both fans with velcro. The front fan pushes air and the rear fan pulls air. The projector now runs fine without shutting off. The fans are 12V and push 34 cubic feet per minute of air. I am very happy with this solution.
