I know that he stated he thought it was 150 pounds - but... that's
not even likely. Think of the last console TV you lifted from back
in the 80's - they weren't that heavy. More like 40-60 lbs.


I had a 32" HD TV by Phillips. It is the largest HD TV made with a
CRT. It weighed 185 pounds. Took two of us to get it unloaded and
lifted onto the stand. A flat screen of that size is about 30#.


I think I'm glad I missed out on the early HDTV fad...

Oh, it IS at least 150 pounds. The tube is HUGE. And the back does
not get smallish, either. The back of the set must be 24" or so at
it's smallest. I have never seen a bigger TV set in my life (that is
like this one). Somebody said it has feet but it doesn't. I had to
pick my left nut off the floor last night because I wanted to see if
there were feet and I was too impatient to wait for anybody to help
me. The bottom isn't flat as there are ridges all around but I figure
that is to strengthen the plastic.

Nonetheless, whenever I was flipping it back up onto it's base, it
took all I had and I hope I am not so old that 100 pounds feels that
heavy!!


Huh. Our heaviest TV is a 32" down in the den. It's not HD and it is a
traditional tube. Kinda ugly, but it was a gift, and it has a great
picture, so I get over the ugly part. It's heavy, but not 100 lbs for sure.
I can get it up on the stand by myself, but prefer a helper - more because
it's so awkward. 100 pounds can feel heavy for me, or feel not so heavy -
depends on what I'm lifting. 100 lbs of TV feels heavy. 100 lbs of female
would be easy to lift on my lap...

My Panasonic 27" crt from 2001 is likely 80+ pounds, so a thirty-odd
incher is surely more.

32" flat screen CRT? Yeah they are that heavy. That's a *lot* of
glass and often MDF casing. Our 1982 vintage 25" RCA table top was
100 lbs.


Damn - I was stronger than I realize back then, I guess. I just put up a
32" flat screen in our bedroom - using a wall mount. I know that one is
well under 100 lbs. I hung a mount that would carry 100 lbs, but only
because I wanted the movements it was capable of. It's quite over
capacity for the TV hanging from it.


An LED or LCD flat screen is about 30 pounds. Much different than the CRT
he has.

I think people are confused by his use of "flat screen" and are assuming
he's talking about an LCD or plasma instead of the kind of CRTs with
flat faces that Zenith developed about 30 years back.

Or maybe they're just kids who have never seen a CRT.

The one under discussion is something like this:

http://www.amazon.com/Sony-KV-32FS120-32-Inch-Trinitron-Flat-Screen/dp/B0002FO3JC.

or this:

http://reviews.cnet.com/direct-view-tvs-crt/zenith-32-flat-screen/1707-6481_7-20604307.html

All you folks who say that it can't be that heavy, note the dimensions,
including depth, and the weight.

Right. The "flat-screen" CRTs used a lot more glass than the normal
curved-face TV. The inside surface of both is necessarily spherical. To
flatten it out the glass has to be made thicker. Glass is heavy. So is the
MDF the cases were often made out of.

"Flat-screen" "Flat-panel"

Or maybe they're just kids who have never seen a CRT.

You would be surprised at the weight that a seemingly light duty stand, will
carry. *There's no need to use two-by lumber for this type of project -
one-by will work just fine. *Take a look at how lighter weight materials are
typically used for applications like this. *You can use 1/8" luan plywood
for the top if you build structural framing under it, for example. *It's
largely a matter of taste, but I don't like the look of two-by lumber for
furniture. *Looks too clunky for my tastes. *150 pounds is not a lot of
weight to support, and it's not a concentrated weight - it's spread across a
32" span. *That is actually in your favor. *It's worth looking at the
commercial stuff that is on the market and seeing if you can get some ideas
from that. *Just remember that you don't need to go the route of building
materials that are typically used to support houses, for a simple TV stand.

Okay, mostly built using scrap 1x4s and one 1x6. I have four 1x4s and
three 1x6s going along the top (which is 24 inches). There are six
gaps at about 1.75 inches. Part of me wants to leave as is and part
says to slap on a piece of luan i have laying around. I also put a
shelf in the middle, as much for strength as for storage.

I may have overbuilt it but the last thing I want is that huge thing
on somebody's foot!!!!!!!!

I have (ugh) a Sony 36" HDTV 720 in a large square tube. It is in our game room
since we moved here. It is heavy. Tube and heavy glass front. Nice picture.
We bought it on the first get ready for HD maybe 10 years ago now.

Actually, I think it may even be cheaper to use a couple 2x12s for the
top and find a piece of thin ply I have laying around to make a shelf.


go to radio shack and get a swivel wall mount, easy and saves floor
space.

For a 30 inch CRT?????

The 32inch flatscreen I removed from my 83 year old friend's den was
at LEAST 175 lbs. Actually, it must have been over 190, because when I
stood on my bag cart the tires didn't give at all, and hauling the
sucker out to the curb, the tires gave significantly.
