Listen closely at the rear of the set for any noise from a fan. Most projection sets have them to cool high temperature areas common in these and if the fan fails, the set will shut itself off before any heat damage results.
If you hear nothing, use a portable fan directed at visible openings in the lower cabinet and see if this delays the shut-off of the set.
If so, the fan is likely dead.

My Toshiba dlp 62hm116 was used for 3 months then stored for 2 years, I turned it on yesterday and it makes a loud grinding noise which I think is probably from the exhaust fan area and the picture is black except white at both vertical sides. It worked fine the last time I used it 2 years ago. Any ideas?
i constantly hear complaints about fan noise in dlptvs
if you sit in front of your computer you will hear the same noise
even in the next room
there is no solution to the fan noise problem
this product has a huge cage fan and a second and third three inch fans in it.... more than the samsung product
it can be noticeable if the tv is on hard surfaces
ie wood floors ,inthe corner, glass top etc
the vents on the back of the tv allow for proper cooling of the lamp at shutoff so it doesnt shatter the tube
its kinda like annealing glass
its designed to extend the life of the lamp ....
which im sure youve priced
call toshiba and tell them your lamp is bad right now and get a new one for an emergency ( warranty if you can do it )
they are also improved
this product is known to have short bulb life
sometimes the zinging noise you hear is indicative of a bad color wheel in the light engine which would require replacement
( not cheap)
toshiba will not piece out the color wheel assembly individually
