How Can I Cool Down My Toshiba Regza LCD?

KJP1407 · 06-03-2008, 11:28 AM

So I'm brand new to this site but need some expert advise/opinions on the issue I'm having.

A few months ago I bought a 32" Toshiba Regza LCD w/ DVD player and mounted it outside my house under an awning. We had the idea that this would be great to watch ball games, etc. during the summer time and we would take it down in the winter (I live in Charlotte, NC).

Well, lately it has been getting hotter and more humid and if we try to watch it around 7pm it will turn on fine for about a half hour and then *POP* it will shut off. I am assuming that due to the heat or humidity it has a sensor that automatically shuts it off so it doesn't get damaged, is that correct? If I turn off the power and reset it (hold the power switch or unplug it) the yellow stand-by light flashes for a while and it will eventually turn back on. Once the sun goes down and it's cooler there are no problems at all.

I tried to put a fan up there to keep it cool but am not sure if it's making any difference as it will still shut off after a while. Are there any other ways to cool down an LCD? Should the fan be blowing into the back of the TV or should it be blowing away?

A ton of people have already told me I'm dumb for putting such a nice TV outside but that is besides the point, right now I'm just trying to find out if there is any way to help it run without overheating or shutting off every half hour until it gets dark.

On a side note I do have a cover for it and all gold plated terminals so that helps keep the bugs, dust, corrosion out of play...

based on the pictures, I'd say the main problem is that the heat build up is not given a way of escape. the heat generated will naturally rise to the top and it appears gets trapped in the space above and behind the tv. the two worst places. If you could get a fan to blow air across the back top of the tv, that might help the problem by clearing out that heat build up in the corner.

Blow the air across the rear of the TV.

Doesn't it hurt your neck to look up like that?

Yeah those adirondack chairs have a nice angle to them so we just lounge while watching...

We played some Wii tennis out on the patio not too long ago as well, that was pretty fun

Thanks for the info, I will try to get a more powerful fan to blow the air out of the corner and see if that helps. I did some research and found mini air coolers, do you think that would help even more or would moisture be a problem?

If you can get a small fan or two near the TV; one to blow air accross the back, and perhaps a second small fan to pick that hot air up and move it away from the TV-- you might be ok.

Lay a thermometer on the top of the back of your TV-- if you can keep this under 105F, you may be fine.

Along those lines, if you are adventurous and somewhat handy, you could pick up a couple 120mm pc fans (get real quite ones) and wire them to a small plug in power source that gives you 12VDC. plug that power source into a switched outlet or a themostat controlled circuit that would allow you to control when the fans are on. Etc....

That sounds like a pretty good idea too... I've come across the PC cooling fans but wasn't sure if they make a power converter to 12V.

I think I might try to find some small matching fans first and try to direct the heat out of that corner. I want to keep the look and everything clean so they have to be able to fit behind the top of the TV.

Thanks for all the replies and comments!

Looks like a double hung window below the TV.
Open both sashes so that the window is open at the top.
This will allow some cool air from the house to flow out and perhaps keep the TV cool enough.
