It's probable that the inside of your Tv might be dusty, first of all i recommned you open the back of the TV and with a can of air (the one you can use to clean a computer) take off all the dust possible because the dust bunnies might be in the way, not letting the tv ventilate, if that does not work it might be that you have a defective fan which needs to be replaced

The lamp needs to be replaced. It's on the back and easy to do. I replaced mine about 3 months ago and it was about $182.00. Hope this works, I know it's hard to fork out that kind of money at this time but once you do the TV will be as good as new. Take care

Air flow is blocked


In the 65" TVS there are 4 or more fans One of these is not functioning Probably the one over the power supply itself This will cause it to heat very quickly and shut down in a matter of about 20 seconds.

only way to find out which fan is not working isw to remove the back.

I get a message that the air flow/fan is blocked, then the tv shuts down. It's not blocked. It's perfectly clean.


This indicates the TV is overheating. Lamp based TVs usually have two or even three fans. One may be having problems or not turning fast enough.

most rear projectors will turn themselves off whenever the lamp is dead. what we call protective mode. in this case the yellow light may be for the lamp. otherwise check if all the fan are working properly.
But MAKE SURE you let sufficient time for the tv to cool off before unplugging the main.

hope this helps

I have a Mitsubishi DLP 1080p TV with air flow problems


Hello ags98,

First I would suggest that you re-seat the bulb and then check the cooling fan, and air flow path. In addition to checking the fan make sure all air flow ingress and egress vent are unobstructed.

I hope this helps

Thank you,

Amber system light is on


had the same issue, we even had a personal fan blowing air behind the tv and the message always comes up right when we turn on the set and the tv turns itself off after about 30 seconds. did some research and it turns out there is no air flow problem just a faulty temperature sensor inside the set. Mitzubishi knew about this since 2006 but didn't really aknowlege it until more recently, they admitted it was a problem with the sensor and are now extending everyone's warenty by 2 extra years so if you got it with a year warenty and you bought it less than 3 years ago, call mitzubishi's 800 number and tell them the temperature sensor needs to be replaced, they'll get you in touch with the nearest service center and a service man will come out and replace the sensor at no charge for parts or labor. hope this helps
