Question about Mitsubishi WD-52525 52" Rear Projection HDTV
We turn the TV and the screen displays the message: "Did you just change the lamp?" We've never changed the lamp or even unscrewed its cover (until yesterday). If we respond "Yes", get the message that the power will be shutting down in a few seconds; check to make sure the air flow is not blocked. If we say "No", don't get any additional message after the lamp question. Either way, the TV shuts off after about 60 seconds, and the yellow status light blinks. Hitting the re-set button re-sets the TV and we can turn it on again, but it will shut off again after 60 seconds. This is the second time we've run into this issue and we've only had the TV 17 months. The first time it happened was when the TV was brand new and although the repair place had it for three weeks, they could not re-create the issue. This is under warranty with Best Buy, whom I called two days ago, and was told it would be at least three working days until they could even coordinate with a local repair place for us. When I talked to the repair place to see if they could give me any ideas to try, they said it will be at least two weeks before they can get it in (and if this is the same problem as before, the TV will miraculously repair itself in between our home and their shop). We've cleaned the filter and removed the lamp and re-seated it. Per the repair person's suggestion over the phone, we unplugged the TV for 12 hours to see if it would re-set itself; "clear the memory" is what he called it. No luck with anything. Does anyone else have any suggestions that we could try here at home before sending it out again? Thanks much! It really is an awesome TV, but for the price we paid, I'd like to think it would work longer before breaking down....
Some of the Mitsu *25's are covered by a factory recall of the optical engine, even if it is out of warranty.
The airflow message is a faulty temperature sensor located near the lamp. Temporary fixes (that will not void your warranty), are as follows:
Find the inlet vent, clean the filter, then place a small fan in front of said filter.
Call a repair company thats an ASC for mitsu, they will replace the sensor (not repair).
Sometimes, when the change lamp message appears, and you try a reset, it does not work. Unfortunately, this is a known problem without a known solution, other than just keep resetting it.

If anyone is still having this problem go to Mitsubishi's web sight. It is being caused by a loose connection. They need to replace a thermal sensor and this is covered under manufacturer's warranty. MDEA has also extended the warranty for this problem alone. Hope this helps someone.

The problem is not caused by faulty surge protectors or lack of air flow. It is a temperature sensor located near the lamp housing. The problem is intermittent, which makes it more difficult to trouble shoot. Mitsubishi was doing everything from replacing the DLP engine to replacing just the sensor. Some techs were claiming to "fix" the problem by relocating the wire. This is not a fix. This is an excuse to abandon the problem. It does eventually go away, only to resurface later. My WD-Y57 does it about 5 times a week. You have to power cycle the set nearly 10 times, which I hate to do because arcing the lamp shortens its life substantially. Unplugging the set for 12 hours is retarded. It's a way to get you off the phone quickly. Nothing requires that amount of time to "reset". A minute or two is good enough to discharge most all of the capacitors in the unit. I only hope that there is a service bulletin on Mitsubishi?s service website that the tech can use. The service manual is no help for this problem. Sorry I am not able to offer a fix, other than to replace the sensor with a new one. The company I work for services commercial and broadcast equipment, not consumer. Attempting to service this outside of the normal channels for me will result in non payment for the warranty claim.

I see a lot of cheap surge protectors with internal wiring problems they sometimes introduce more problems than they are worth that may have been your problem all along with a possible loose ground returns in your electrical box the bus bars for all the wiring get noisy in an older house and need to retightened the mitsu tv has a little round reset button on the front panel it is only accessible with something like a ball point pen there is also a new style lamp for the tv , make sure you get one and keep the filter clean in the back it will extend the life of the tv dont attempt to constantly restart the tv if you suspect the lamp then follow the directions on the front panel and inspect the lamp you know when you see a bad lamp this product also has an intermediate mirror that likes to get dirty make sure you have them clean it or replace it itll help the pic quality

Tips for a great answer:
The lamp timer on the Hitachi projector must be reset whenever the lamp has been replaced. The "Lamp" indicator on the display will light red or the "Change the Lamp" message will display when the lamp timer needs to be reset. Hitachi recommends that the lamp timer never be reset without replacing the lamp and to always reset the timer when the lamp is replaced. The message functions of the projector will not function properly if the lamp timer is not correctly reset.
Turn the power on. Press the "Reset" button for three seconds until the "Lamp xxxx hr" message appears on the lamp timer on the bottom of the screen.
Press the "Menu" button on the remote control while the lamp timer is displayed.
Press the left arrow button. Select "0" and wait until the timer display clears.
