I'm hoping I might be able to do it myself as the set is definitely out of warranty (3+ years old and I didn't buy an extended warranty).
My experience, exactly. Lately, I can hear the fan as
soon as I turn the TV on, which wasn't the case until
a few weeks ago. From time to time, I can even hear
it over music or movie audio.
However, my case is a bit more complicated... As soon
as I got my WD72833 (about 3 years ago) I added a
foam 'chimney' to the back of the set (to quiet the fan
down) and mounted an extra 120mm fan inside that
chimney (to counteract the chimney airflow resistance
and maybe assist a bit in cooling). This completely
eliminated fan noise (though I could still hear it, faintly,
in the dead of night, with nothing playing).
So now, I am not sure which of the two fans has
become louder; could be both. As soon as tax season is
over (taxes come before pleasure), I plan to pull the TV
from the system, take both fans out and see which is the
culprit. Or maybe just replace both -- I reckon they've
accumulated about 4000 hours of operation, not to
mention the cost will be minimal.
