it had to be near 200 pounds (probably exaggerating, but it was heavy and extremely awkward to hold while moving with two people)

Only as anecdata, I stil have and use daily a "huge" Sony 32" trinitron as TV:

that is 75 Kg/165 lbs, so 100 Kg or more for a 36" seems just right (as said on the other thread I have a special table/support for it).

And BTW the only reason why I changed my good ol' (as well trinitron) 20" inch computer monitor with a "flat" 22" screen is because aging I see better the screen at a slightly increased distance (i.e. thanks to the reduced thickness I can have the screen some 30-40 cm farther on my desktop).
