Question about Toshiba 62HMX84 62" Rear Projection HDTV
For the past two months the fan has been louder than normal. A couple of days ago the fan got extremely loud and the picture became shaky...like it was about to go out. Finally, it did. You could still hear the sound but the screen went to total blackness. Now when I come home...I can turn on the tv, but after about 30 minutes the same thing happens again. Is this the light engine...or a problem with the cooling fan? Has this happened to anyone else...and if anyone knows whats wrong..what do I need to fix it? Thanks so much for the help guys....
HERE ARE A COUPLE OF STEPS TO FIX THIS PROBLEM WHEN IT OCCURS:
1. clean the filter an fans regularly (every 4-6 weeks or less) to provide an air flow
2: oil the fan bearings annualy with vegetable oil or motor oil
3:regularly change the lamp, it loses intensity as it continues to age, and it produces more heat *** it's arc blackens as the heat reflects back inti the lamp, there have been a few cases of exploding lamps as they were dangerously worn, and lost almost all intensity, check the arc is in good shape every 4 months, this should increase the life of the television aswell, I had a DLP TV that I did these checks with, and it was over warranty by 5 years before it gave up and died!

I would suggest to replace the fun to keep the light running cooler, the reason you loose the video after a period of time is because the fun is not providing enough cooling.
If the fun is noise it means the bearings inside of it are not working well anymore.
Let me know if you need more help.
