Not really computing related. Just thought I would ask. How long is the life expectancy of an LCD TV? Especially if left on most hours of the day?

Like any electronics, that is highly variable. It may outlast you or it could quit as soon as you plug it in. I've seen high quality electronics die suddenly and low cost stuff that is still going strong after years of constant use. There are way too many factors involved, such as heat, vibration, humidity, low or high voltage, surges,component quality,physical abuse, etc. to pin down a "life expectancy"
Cost or time in service often has little bearing on the lifespan.
You might as well be asking "How high is up"? or "How long is a peice of rope"?

I agree with Wizard. Buy quality and you should be okay, but not always. Think of it as like buying a new car, it's been shown over time even quality builders can produce lemons.
We have Samsung LCDs and LEDs, both monitors and TV's, and would recommend them, I'm sure there are others that folks can and will recommend.
Now last April I ordered a Samsung 46in LED Smart TV from Amazon. When it arrived and we unpacked it something just didn't look right. On closer examination we saw the TV was bent, yes bent. How does that come off the production line and pass inspection. 
In three cases we use the TVs as monitors, screensaves are used. It might be hard to address the long hours of use.
EDIT: Nice link RedneckDude

Thanks for the link RedneckDude. However how do I tell what backlight source my TV uses?

Didn't come with one. Company says everything is posted online. I went to the website and read through the manual. No mention of what kind of backlight the TV employs.

Kona...post the brand and model number etc....perhaps someone can have more luck hunting down the info.
Many televisions use componentry from external sources...

Why do you want it on all day?
Seriously, there are only so many times you can watch Avatar.

I hooked my step-son up with a 26" HDTV. I have his PS3, xbox, and PC hooked up to it ans he's on it all the time for close to three years now with no issues.

It's tube-lit.
Generally speaking, if it's a couple of inches thick it's probably tube-lit. If it's extremely thin, it's probably LED-lit. LED-lit sets have only become common in the past year or so and generally cost more, and you can rest assured that stores make it a point to advertise LED-lit sets as "LED TV" to make it seem like it's not an LCD. But the difference mostly a matter of power and longevity. LED-lit sets actually have poorer color reproduction unless you spring for the high end ones with full-screen lighting that adjusts with the picture brightness.

I have a Phillips LCD which is getting close to being 10 years old. Still ticking along just fine.
