Can someone explane how to build a waterproof cabinet for an LCD or Plasma Telivision?

I want to build an enclosure for my television to withstand the floridian climate

what lever of water proof - literally or just moisture resistant?
With the TVsheild you have to buy silica gel that absorbs moisture and once this is done the gel is useless! Otherwise you have to pay alot more cash on a cooling system but no heating solution is offered, so you cannot watch it in your spa.

Water does get into the TVsheild.

just a small point Silica gel can be reactivated by heating in a low oven to drive off the water.
Drying out the gel would not replace the TV :(

Thanks anyway.

Good point, if running a plasma TV , you don't have to seal it.
Just strike some balance between allowed electronic heat and
the heat needed to drive Floridian moisture causing mold out
of the unit before it can disrupt operation.

Actually not really "water proof" persay. but as you suggest water resistant would be acceptable as it would be mounted in a screened in area with a roof. The only direct type moisture would be driven in from a heavy rainstorm. Something such as a peerlessmounts
would be awesome just not for $2k
We bought an lcd enclosure and it cost $999
Spray it with WD40 on a regular basis - say once a month.
WD40 would actually attack the screen over a prolonged period.

How to cool a plasma is a nightmare.
A 50" plasma uses 450 Watts
That means, if you enclose it you will need to make a 450 watt heat exchanger.
You may have to use liquid cooling.
Sorry about that.

There are AC units that can fit onto the enclosure, just ask the manufacturers.
Hi all. Came accross this forum, and have some great info for everyone based on my own personal experience with TV Enclosures. I researched LED,LCD,PLASMA water resistant enclosures for years, looking for something other than the 4-6k outdoor TV's (too much for me and wifey) and/or the 2k enclosures on the market in the past. I found a company online, called The TV Shield and was able to purchase a water resistant (they don't say proof as it has vents for the heat build up) TV Enclosure, for less than 600 bucks, shipped. It arrived in 3 days and was very easy to install and very light weight as it is constructed from plastics. The front opens as I read above, and props open, and it also locks shut. Called customer service as I had a question about mounting the unit, and they were very helpful and referred me to an online video.

Check it out. May be the answer for everyone coming to the forum.
Went and found The TV Shield website for you all, you can find them by searching for The TV Shield and/or going directly to their website at www.thetvshield.com
We ordered one enclosure from tvsheild and had to replace it within 2 months at it let in water and the due to the body being plastic wast broken into and the screen stolen.

DO NOT BY A TVSHEILD they do not work!

We found a number of manufacturers of steel enclosures, and found one in Jersey, went saw a demo and bought the replacement - never had a problem with the replacement.
There are many solutions for protecting outdoor TVS, one off the best we have used is http://www.lcdtvenclosure.com/lcd-enclosure.html and they ship globally.

There units can be left out in all weathers form sub zero to 60C! These units come complete with a cooling and heating solution.

Just to raise a possible complication: Do you ever get dew on surfaces overnight? If so, you risk having that accumulate in/on the LCD unless the case also excludes humid air.

I suppose you've already rejected just propping it inside a window, inside the house... or projecting from inside the house.

what i had intended wo do was using sheet metal avialable from HomeDepot, bend cut and seal with silicone a backside to the enclosure. Using a circular cutter make and rubber grommets make a hole for the inlet and outlets for electronics. Hinge the front so it get pulled forward to open suppeted by small chains. what i am getting hung up on is how to get some air flow. i mean i could just design it with a detachable cover so to watch, the front face is removed via clips. Sort of like a pellican case

Edit : or insead of sheet metal, using clear thick plastic grooved so pannels interlock with one another. Glued and siliconed. Or conversley with L brackets on the ouside and bolted together with silicone.
Wood is easier to work with than either plastic or sheet metal, and can be made adequately waterproof with suitable paint and stain (your house being evidence thereof). Caulking, if needed, would be the same either way.

If you're going to use a solid cover rather than glass/plexiglass, you'll have to open that cover to view the thing... so turn it off when not in use, and count on the open cover to provide air circulation when it's on. (Design the box large enough that there's some clearance around it, and it shouldn't be much worse than having the flatscreen mounted to a wall....)

I would think that normal humidity wouldn't bother it. They are made with that in mind, after all most of the Pacific rim countries have high humidity. Now leaking roofs or outside rainwater would be a different story. As the others brought out if you try to seal the cabinet you are going to have big time heat problems. Altering the enclosure might also void the warranty. About the most practical thing to do would be to get a small air conditioner and direct that at it.
They make liquid cooling systems for computers, I have used them before. But they are designed to pull the heat from the small area of the processor so it would be very difficult to adapt something like that to cooling such a large unit. They could not even pump enough water to make a difference.
You could also create for yourself a condensation problem if you use an active cooling system.
