i have had my toshiba 42 inch plasma for around 2 years now..it had been mounted high up on the wall due to kids !... only used about 6hrs a week for movies. i have now bought it down into a large cabinet . i had never thought to feel how much heat it produces when it was on the wall , but checked it after about and hour , of first veiwing in its new spot i was surprised to how hot the top rear panel had become. and certainly felt that the screen had become much warmer. i mean it felt too hot ?....which seemd to also affect the plastic sides of the tv also. there is plenty of space in the rear of cabinet for ventilation, at least 18 inches with an open back also ....and i have now drilled out about 10- 3 inch diameter holes out of the top of the cabinet to let the heat escape upward from were it felt very hot. to me it seems it has not cooled it down . so is this normal to be hot enough to make you move your hand away after 30 secs or so .....can i add a quite fan in the rear of cabinet....would it help ??? thanks for any advice.......

Yes, they do get hot across the top. It's my understanding that's where all the heat vents from on a plasma. I own a Samsung and it does the same. It's probably been doing this for the 2 years you've had it and you just didn't notice. Maybe one of the techs will chime in here, but, I believe this is normal.

After two years, I imagine there would be some dust accumulation in the vents, and in the wrinkly bits inside the TV. I don't know if you can vacuum it out, blow it out with an air compressor, or what.

Just a thought.


oh, btw: solar plasma can be millions of degrees. Posted Image

Jason: My Panasonic plasma is in a built that has plenty of room for ventilation and when it has been on for a couple of hours I can feel the heat from it when I walk by it. Parker

but a fan probably wouldn't hurt (much.) Plasmas get hot; the newer ones aren't as bad as the older ones - the first one I saw was a 20" diagonal (yes, twenty inch,) that demanded, I believe, 2200watts of peak power. The top of the screen was always a bit wavy due to the hot-air distortion in front of the screen. It was... ridiculous, but also still a "technology demonstration" stage product. But they still get hot, and boxing them in isn't a really great idea. The vents are a help; moving a little air through the screen will likely be a big help. Leo
