Mitsubishi WD-Y57 When set is plugged in lamp lights right away however the cooling fan doesn't run right away. If you turn the set on and off a few times the fan will sometimes come on. If you turn the set off the red standby LED will sometimes cut off and the set will not come back on. If you happen to get the set to respond trouble code 34 is activated. The lamp has been replaced. Thanks, Ed

Mitsubishi rear projection DLP keeps turning off and shutting down. The red light then turns on for a while and then turns off. TV can be turned on again and works fine until a random shutdown occurs again. No fault codes are stored. No blink codes. No airflow warning messages. The original thermal sensor was replaced 8-1/2 years ago. Fans are completely clean and running smoothly. I fixed this problem by replacing the 8.5-year-old thermal sensor. The problem is gone. Mitsubishi thermal sensor part number 299P313010A. Manufacturer part number YS11A95B-C6. Do not use the connector plug. Strip the wires, and hard wire and solder the 2 connections. This might also apply to these models: WD-52631, WD-57731, WD-57732, WD-65732, WD-57831, WD-65831, WD-Y57, WD-Y65

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.

If you did not have this issue before replacing the lamp remove it and look to see the socket it plugs into is not bent or damaged (it is possible when inserting to not get the two pins lined up correctly.

The lamp cartridge has to be installed precisely so it plugs into the socket and also the lamp door must be closed and secured.

This question for some reason is posted here two times--see my previous answer here.

hello is the lamp fitted securley and the lamp cover as well

check and clean all your fans and check to make sure lamp door is closed properly

have you checked the lamp?

If the red light is the lamp light then the projector lamp is defective.

yes , u need a new lamp shop around , cost less

There are a few reasons that this could be happening first one is maybe the lamp died on you, Afraid there is no way to test this other than replacing the lamp. The second problem may be 5 capacitors on the power supply that hold the 12 volt line low and do not allow the light engine to start properly.
First thing you have to do is listen to how it trys to start, It should sound like this, first when you hit the power switch there may be a click then within five seconds the fans then a few seconds more you may here a sparking noise, if all this is happening then you most likely just have a bad lamp
