    TV longevity

    please don't call me a spanner if this question appears on other forums I belong to because I am of limited income and buying a new flat screen TV is quite expensive. So it is very very important to me to get the right answer on this one. I was recently in a Best Buy store looking three place my now not working CRT television which must have lasted at least 17 years or more. The salesperson responded to my statement that the reason I was looking for LED backlit television was because I was reading about longevity than I would like my new television to last as long as my old one did. He told me it was no reason to buy LED backlit television over fluorescent backlit television because of longevity even though it may be true those LEDs will last longer a television of any kind won't last long enough for the back with lighting to be at issue. New televisions and all consumer electronics are only designed to last five years and the power supply will go before the backlighting. So what do you think of that? Is it true? And where else might I ask this question to feel I have gotten the infinitive answer? I enjoy these forms very much and feel they are the place for highly technological answers. But will also like to doublecheck this question that both a highly technological and television specialty forum. But please don't let that deter you from giving me an answer I just want to be very very sure of the answer to this question.

    Last I heard' a design life of 3 years is what is used. So it they have upped it to 5, that is better yet.
    Now for operating cost. See what they use.

    My 19 inch CRT drew 1 amp and my 26 inch LCD draws 2 amps.

    I tend to take the attitude that I expect something like a TV to last 5 years, and anything over that is a bonus. Although, as your example shows, you can sometimes get lucky, I really don't think it is realistic to expect another one to last as long.

    If I had a choice, and there wasn't a big price premium, I would definitely go for LED backlighting. Even though CCFL is very reliable, I would expect LED to be even better, and to be cheaper to run too

    Maybe I'm under the wrong impression by a thought flat panels themselves were not that old unless you were an early adopter. It might be helpful if some of you all could say how long your flat panels have lasted and what were the technology employed backlight ccfls or led backlit, plasma etc.
    thanks

    Perhaps I need people is old as my our 61 years to chime in? I never remember a television listing is little as five years but of course I am talking CRTs.

    I be 68.
    And yes, they were designed to last a certain time and need replacing. If fact GM has the same old 60,000 mile transmission in some pick ups.

    Modern LCD tv manuf's mostly claim their tv's will last around 60-80,000 hours. Plasma tv's around 30-60,000.

    80,000 hours is 3333 days which is about 9 years of continuous use. If you watch tv 12 hours/day
    then the lifetime would theoretically be twice as long but in real life less so.

    marcmiller--If you really want to save money, buy a plasma flat panel. And even there you can save by buying the cheapest which will scan only 720p versus 1080p for the more expensive. But can you tell the difference?
    I do not think longevity is an issue.

    If you put a lcd next to the new led , you can see a little difference in the clarity.
    I have two 1080 sony Bravo's , problem is the tv stations only broadcast in 720. If you are not watching on blue ray disks you won't see any difference .
    Now they came out with the 3D TV .

    In LCD sets, LED became THE back lighting technology because of the difficulty in achieving superior black levels with fluorescent back lighting. The goal was not and is not a longer lifespan of the TV.

    If I was in the market today, I'd pick LCD over plasma. While plasmas have improved a great deal over the years, have great black levels, and they can often be cheaper to buy, I still seem to prefer LCDs. (I am not in the market because I still run my older 52" JVC 720p LCOS set. Still looks awesome!!!!! First time I saw an LCOS set I was knocked out and still am! Unfortunately, thin appears to be in and LCOS wasn't thin... )

    LCD's should last a very long time unless there is physical damage. The backlights are typically rated for 50,000 hours.

    Hi, for me , I think it doesn't matter on what kind of home TV brand or type one has. I guess, its a matter on how often you used it. However, we do have LCD and LED so far but I have not experience any technical difficulties yet
