Question about Mitsubishi WD-57732 Projection Television

1 Answer

On-going problem where tv is turned on and almost immediatley says it will shut down because of an air-flow problem. After turning on several times it used to then work but lately it just repeats the same message and shuts down after 30 seconds. yellow status light comes on the lamp light flashes. Been doing this most of the 3 years since I bought the tv so i don't think it's the lamp but some sendor problem where it thinks it's overheating or something. Any help would be greatly appreciated. thanks

I have a mitsubishi 1080p wd-65731 just replaced lamp , tv comes on works fine for about 30 minutes and then shuts off , cleaned vents good , has good air flow light that says lamp turns red in the fr


Could be the fan. It will cool tv but could also be to much for tv to handle.
You can also try reseating the lamp. It may say ok but be wrong.
I have a Mitsubishi 5500 projection tv . have had the type of issue you have had and I have replaced a lamp as well.had to reseat the lamp three times before it worked without shutting down.
Hope this helps.

Mitsubishi TV, WD 60735; TV shuts off shortly after powering up.


It could be but a couple of other possible reasons---they had problems with this set and its brothers with caps in the main power supply puffing up and causing this "hard to turn on" issue.

A second reason is dust/dirt inside the unit.

All air is coming in via the front of the set and exits the rear--enough dust gets inside and the fans slow down or the lamp gets too hot and set shuts down---don't try this in the house: we take them with back cover off outside the building (on a ramp) and with air clean them out completely--try not to blow it inside the screen. It looks like a dust storm in most cases but can cause exactly the problem you have.

That is computer problem, it shutsdown by itself improperly that is why you see the message on the screen.
When was the last time you blow out all dust inside the PC. You should also try reseating all the cards and memories. Also look for any caps on the mother board with bulging tops.
That will be your starting point.

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.

please rate my help++++Thanks for using FIXYA

Furnace not starting


That small tube is the vent verification hose. Air passing over an oriface creates a vacuum. This negative reading, usually about -0.4 inches of water column is enough to trigger a vaccum diaphram switch telling the unit there is enough air flow through the unit to support combustion and remove byproducts safely

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,
