so the top of the stairs is about 4' above the base of the tv...

the cooler the better, but 80 f is probably ok.

i'd cut holes into the closet near the tv base and the top of the closet.
>the opening around the tv is about 1/2" on each side and 2" on the top.
if the tv uses 150 w (512 btu/h), a 512/10 = 50 cfm airflow would make
a 10 f temp rise from 70 to 80 f... 50 cfm = 16.6asqr(4'x10f) makes
the vent area a = 0.47 ft^2, eg two 2'x3" slots.
