Air flow error message again and again....


A few of these sets did have a issue, the lamp cartridge had some fine metal mesh around a few places where the airflow from the cooling fan contacts it, that mesh if there gets blocked with dust and will give this error as it is really the set detecting the lamp temp is too high.

If you find that, clean the mesh free of dust, careful not to drive the dust inside onto the lamp face itself.

Other than that dust on the fan that cools the lamp can slow the fan just a little and the set will detect this also.

My y65 has a new bulb when I turn it on yellow light come on within a few seconds and a check air flow message come on the screen tv then turns off if I wait about 30 seconds I can turn it back on again...


ogrady1428,

I would check the filter on the fan intake first. Remove it and carefully clean it with compressed air.If this does not resolve your problem then I would remove the lamp and inspect the switch in the vicinity of the door for problems. Be very careful reassembling the unit once the door is removed. The interlock swich must be positioned correctly or you will get an error message. I have a tip at http://www.fixya.com/support/r4168009-change_lamp_in_dlp_projection_tv which explains the problem and how to fix it.

Thanks for using FixYa and for the generous rating. We answer these questions for free.

Tv says airflow restriction tv will turn off. there is no airlfow restriction


I did not find a reference to airflow restriction in the service manual.
I don't know if this will help, but here are the error codes:

The TV must be in “Shut Down” and not manually switched Off, to perform the Error Code Operational
Check. When the TV is switched Off, the code automatically resets to “12” No Error.
Press the front panel “DEVICE” and “MENU” buttons at the same time, and hold for 5 seconds to
activate the Error Code Operational Check. The LED will then flash denoting a two digit Code.
Note: The front panel buttons must be used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times.
• The Error Code is repeated a total of 5 times.
4. Error Codes
The Error Code designations are listed below:
Error Code Probable Cause
12 No error detected
22 Recovery from momentary Reset
32 Lamp Cover open
33 Air Filter Cover open
34 Lamp abnormality
35 Chassis Fan failure
36 Exhaust (Back Cover) or Lamp Ballast Fan failure
37 Engine (DMD or Lamp) Fan failure
38 Excess Lamp Temperature
39 Excess DMD Temperature
41 Short Detected
44 DVI Cable (between Chassis and Engine) disconnected

Have a mitsu wd-52631 - get message "tv will shut down in a few seconds - chk for air flow blockage" then shuts down - wil turn on after sit for several hours. No blockage evident.


Well....the reason you are getting an "airflow message" is that there is a thermal sensor on the BACK of the lamp cage, and the connections on it get to be "intermittent" after awhile...and when this happens...the computer thinks that the lamp is overheating due to a dirty filter or fan--and shuts down the set.

It is a small, white plastic sensor, with 2 wires on it, that go to a connector and it has a black and red wire(usually) in a twisted pair that connects to the sensor connector. The connectors need to be REMOVED and the sensor HARD-WIRED (directly connected to) the other pair of wires. IF you have done some electrical work before...this is easy. You only need about 3" of spare wire to patch in between the sensor and the other connector, after you cut the connectors off. BUT...if you do NOT have repair experience...I suggest you call a COMPETENT, FAIR tv shop in your area, if you do not have a service plan...and tell them you have a mits. set that needs the "airflow sensor problem" repaired . this CAN be done -in-home, in about an hour or less, and for under 300, including service call.

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
