led life span?

[clouso]

does anyone knows or have any idea about the lifespan for led tv's?...i heard it should last longer then usual lcd's!

I've seen the "100,000 hours" figure quoted in different places. Then again, all sorts of arbitrary numbers are being used these days (70,000 hours for plasmas, 80,000 hours for regular fluorescent-lit LCDs), so I take ANY claims with a large grain of salt.

In all practical terms, the LEDs themselves ought to last longer than the liquid crystal panel itself. In other words, the LCD panel will start to degrade before the LEDs behind it start to go.

thx...so i will at least expect a 80,000 to 100,000 hours lifespan!

That is all theoretical. 80-100,000 hours may be how long the LED lights themselves will last but chances are something else will go wrong with the TV before that time comes. Power supply issues are quite common, especially in Samsung sets. Sony has had a fair number of panel issues (very pricey repair). Many of the cheap third tier sets just fail after a year or to (usually power supply related).

If you get a good brand you should get many trouble free years out of the set. Even though I have seen quite a few Samsungs with power supply problems I don't think the chances of any one person having issues is that high.

If you're looking for the most reliable TV, my experience is Panasonic is where it's at. Their less than 2% failure rate is the best in the industry and I work at a service center where we see FAR fewer panasonic sets in for repair than any other brand and we sell a lot of Panasonic. The few we have had in (for relatively minor <$300 repairs) have impressed the tech with how well built, engineered, and modular they are. Many sets have all of the components crammed on to one or two boards or, even worse, the panel itself, which brings the cost of repair into prohibitive territory very quickly. I don't have any pictures of the inside of a comparable Samsung but I can say it looks like a barren wasteland (one or two boards) compared to this:



That's the inside of a Pansonic TH-PZ700u and the tech says that is one of the best engineered and layed out sets he has seen in a long time. That's not to mention that for 1/3 the cost plasma offers superior picture quality to any LCD - LED backlit or not.

if you see my signature here i just bought the toshiba led 55sv670u...and to be honest i saw it side by side with panasonic v10 series and also the sony bravia and the toshiba had better PQ..i was just wondering about the life span for led ...and for toshiba i had a dlp before and never had any problems so i expect the same with my new led tv...thx!
