Tv mitsubishi wd-y57 funciona normal mas alguns minutos depois desliga s?zinha.

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

Susie, try removing the lamp assembly, and blowing out the ventilated area on the lamp assembly housing. i had this issue on my wd-y57 recently and that solved it.(mine was really packed with dust...) i made sure to hold in the system reset button after doing this (located in the controls panel on the front of the tv) but not sure if that is necessary.

Go to http://www.download-manual.com/shop/Mitsubishi-wd-y57-TV-User-Manual-pr-28625.html

Pay the $8.95 to download the manual and the procedure is explained there.
You really should get the manual anyway to help you with mots issues you may have in the future.

Cheers

have you checked the lamp?

since dlps use a color wheel to make the color the color wheel may be going out. get it serviced
