Anyone know if I can put the TV (Samsung LN46A650) in front of a window that gets sun many hours a day.?

Like this:
Code:
--wall-----[--window--]---------
|                 TV???            |
|                                |
|                                |
|                    seat           |
-----------------------------------
I'm in San Diego, and I think the outside temperature will never go over 95. I'm not sure if the internal temperature inside the TV will get hotter, like when you leave something in the car.

If I'm actually watching the TV the knockout blinds will be closed preventing directl sunlight from hitting the TV. But probably 90% of the day the TV will have sunlight at it's back.

My Sony CRT was in this position for many years with no ill effects.

The manual says (Page 101):
Operating Temperature: 50°F to 104°F (10°C to 40°C)
Operating Humidity: 10% to 80%, non-condensing
Storage Temperature: -4°F to 113°F (-20°C to 45°C)

Any opinions?

I put mine in front of a window. There is a shade on the window and I have only had it there for a few weeks, but no problems so far.

I am kind of curious what the affects of the sun itself on the screen? The panels are plastic and will turn yellow even without direct sunlight eventually if not treated. Not sure if they think of this at this when they make these sets. Some over the counter products such as Plexus have a UV agent in them but I am afraid to try this product on the screen itself.

I hadn't thoguht of that.

I am proposing placing the TV with it's BACK toward the window so sunlight does not fall on the screen, but on the back where the input panel is.

The sun will discolor the plastic.

I would be very hesitant to put a high dollar piece of electronics where it would get hours of direct sunlight per day. It might be just fine, but it seems like a big gamble to me. Furthermore, San Diego is pretty far south, so the sun is going to be pretty hot.

It's your TV, you can obviously do what you want. But I wouldn't do it.

The problems you'll run into are the suns rays making the electronics run hotter and UV radiation discolouring the plastic. Nothing too serious, and you should be able reduce the effect of both to a certain extent. Alternatively you could just close the curtain all day.

Our window has a top down shade installed, similar to the one here:

http://www.yourblinds.com/products/c...hades_TDBU.asp

I had never thought about sunlight discoloring the plastic, though the screen gets less direct sunlight now than it did before. Not sure how big of a concern that should be -- I know lots of people with very bright rooms -- glass walls, etc. and have not heard of that being an issue. But heat is another matter. If you keep it in front of the window, installing some sort of window covering would make sense.

I can mitigate this by closing the blinds when the TV is in use.

I can't close the curtains, my cats DEMAND that that room is available for laying in the sun. The room is east facing and gets the morning sun. By noon the sun is in a different room in the house.

If the black plastic on the back gets discolored I'm fine with it. i just don't want the TV to melt.



But cats rule my world.

I don't think you need to worry then.

Those wanting to put a newer hd tv in front of a window, this is actually fine the old rule of don't put a TV in front of a window was mainly for old tube TVs, like consoles and earlier TV's because the hot sun would over heat the tubes and cause them to shatter like when a light bulb gets too hot. There is still only two main issues you would have to worry about like discoloration, however most TV's now are made of a plastic that resists discoloration. The other may be that it could possibly overheat and melt some of the soldering inside but again they do have protection for that because general use heats the TV up to around 80 to sometimes 120 degrees possibly higher depending on the room temp, and where you live. So in all honesty newer TV's made after 2007 should have no issues really, the discoloration can happen from about anything but it would take about 15 years and most people don't keep TV's that long anymore. As for over heating I wouldn't worry much the main thing you will need to worry about in my opinion is dust. Windows tend to attract dust like magnets and you're TV creates a lot of static electricity which attracts dust, so in all as long as you keep up on cleaning it, dusting it and so forth then it should be fine.

Also if it does get a bit hot there is things you can do, the instructions say a operating temp but most TV's will operate over that on their own I don't think you have much to worry about but as a added note you can do more damage if you put the tv directly across from a window which WILL damage the screen.

I would hope they are a metal blind.

I would expect a lcd to be damaged by direct sunlite,
I had some lcd watches damaged by the sun.
