    Hi I am thinking of buying a plasma and popped into Curry's (wouldn't buy there) for advice and info. Was told not to buy Plasma as they burn out within 7 years better of buying digital rear screen or LCD. Never heard this before can anyone help me? I don't want to spend £5,000 on anything that is going to be useless in such a short time. Thanks for any help wildwill

    Theres a good load of LCD's which have excellent pictures.
    Your right, an LCD should last longer (I ive just been told the sharp will last twice as long 60'000 hours lamp life.

    Look at the 30" and 37" Philips which i saw today in a Curry's and was excellent. I'll probably get the 30" model and look at the sharps.

    However this is only going to be a daytime tv viewing screen for me as i intend to go Projector, after selling my plasma due to living in fear of it breaking down. It broke down once and Pioneer replaceed it with a brand spanking new one (but had i no cover it would have cost thousands to fix or been a write-off!!).

    S.

    Good luck.

    To a large extent this is a question of size.

    Currently LCD's are filling the small->medium screen size sector, with palsmas generally filling the medium->large sector.

    If you want a 50" screen, well I don't think anyone is doing an LCD that big yet (and to manufacture something that big would make it VERY expensive!) so plasma is your only choice (of the 2).

    If you are looking in that medium (30 odd inch) sector well... personally I'd go for a good old CRT, but LCD is theoretically sharper (but a good plasma will still beat a poor LCD) and longer lasting, but most people say a home plasma will last you at least 10 years.

    On the life issue, ask yourself this - how old is your current TV that you are replacing? Chances are it's about 10 years old - the same as a plasma should last you.

    Anyway, I'm sure they (manufacturers) will have found some way to make almost anything you buy obsoleat, so you have to buy something new from them in 10 years time anyway!

    Depends on what use you want it for. I have been looking to buy a largish (40") display and found they all have flaws, but it's what you willing to live with.

    Rear Projection : Large and relatively cheap, but very small viewing angle and the screen burn issue is very real.

    LCD : Don't suffer screen burn, have long life (like snowman said), but have problems with brightness, size and hadling fast moving action.

    Plasma : Best picture next to CRT with the benefit of size and live as long as CRT, but cost (not as much LCD though) and can get burn-in easier than CRT (getting better in this area each year though).

    Personally i am going for a panasonic plasma as i watch lots of dvd's and ps2.

    My opinion is Rear Projection is dying, plasma and lcd will battle it out till one removes the flaws (though plasma has a head start by a couple of generations).

    Snowman, just curious what was the pioneer model?

    Ability of LCDs to handle fast motion improves with pretty much every new model. They are getting very very close to other technologies. As for brightness - I'd say that (from what I've seen) they can easily match Plasmas.

    There's a big Curry's store near to one of the couriers we use and I pop in quite often to see what they have on offer.

    Its pretty amazing the nonsense these stores give out - I still hear the 'dont buy a plasma they need re gassed' story every time I'm in one of these stores.

    Any current Plasma will last way longer than most owners will keep them as their 'primary' viewing screen.

    LCD screens are not guaranteed to outlast plasma displays - the 'lamps' have a 'projected' life of about 60,000 hours - though who knows what the image will look like by that time (or by 30,000 hours going by how most LCD projector lamps look after half there estimated run time) and try and get spare parts in five never mind seven years for a product that had a 12 month (or shorter) life cycle!

    Best regards

    Joe

    However, there is (as I'm sure you are aware) a huge difference between the lamp technology used in projectors, and that used in direct-view LCDs. The latter is more akin to a fluorescent tube. And we all know that, aside from some darkening of the ends, a flourescent tube maintains a significant proportion of its light output and colour for a prolonged period.

    And, in any case, 30,000 hours is going to be easily more than enough for many years of typical TV use. At 6 hours a day (excessive?) that works out at 5,000 days (or a bit shy of 14 years). Drop to 3 hours a day and your backlight's half-life is 28 years. Take the lamp to its full expected life and you are up to 56 years.........

    And I have yet to see any real evidence that the LCD panels themselves deteriorate to any great extent during use.

    Nigel - your argument re large no of years also applies to Plasma. I wouldn't worry about it at all as an issue for either technology - in 5 years we'll all have moved on to the next toy anyway.

    Agreed, assuming that the likely life of a plasma is (say) greater than 3 hours x 365 days x 7 years (or about 7,500 hours) - which it probably is (D.O.G.'s aside).

    Plasma Tvs have been around for a while now and alot of testing has been done on life span both by the manufacturers and independants as you would expect of something costing the sharp end of £2000.

    Basically they run the screen at maximum contrast and brightness with a pure white source 24hrs a day to calculate the screens rate of decay (Or so I believe).

    Apparently based on 4hrs use per day (Average use) after 12 years a plasma screen will have lost around half of its original brightness / contrast (I have seen these figures mentioned on a few sites).

    But the better panels all have brightness and contrasts of 1000 odd (And with the pannys contast is 3000)

    I only have my LG17 panel at 50% contrast and brightness and the quality is still brilliant. So if it looks like that after 12 years wheres the problem with life span ?....... There isnt one.

    I agree with the previous post. Who will really be bothered in 7 years. I will be bored with mine in 3 - 4 and it will end up in the kitchen / bedroom and will want something else.

    On the question of LCD screens my understanding is the technology is pretty much at its limits and there are problems increasing the contrast levels much above there current levels (800 was mentioned this is far below that of most Plasma screens)

    It is also problamatic manufacturing the panels at42" and above so dont expect to be seing LCD screens of this size widely available in the near future.

    If you want a big screen TV with decent quality Plasma is the option I reckon. Or if you have a room to dedicate to it LCD projectors produce excellent results and can be picked up pretty cheaply.

    Wait for it though Nathan Silly will be along in a minute to tell everyone to buy an RPTV. The quality is so must better than that of Plasma apparently :laugh: :laugh: :laugh: :laugh: yes I just fell off my chair.

    Thanks for your help everyone it seems the salesman was wrong as I thought will be looking seriously at plasma as we want at least 40" screen for the living room.

    Hello Nigel

    As you say LCD Projection lamps and LCD Panel lamps are quite different - I was trying to get across that the 'expected life' argument is a Red Herring.

    I wonder what the 'expected useful life' of a Curry's AV Specialist is :)

    Best regards

    Joe

    I would have thought that the words 'Curry's'* and 'specialist' are never properly used together in the same sentence.

    The expected useful life of one of these specialists comes to an end right after they have read out the contents of the shelf-edge label to you in response to your request for advice.

    Thanks for that article Nigel interesting. Having read that I still think it will be a year or so before LCD that size will be out there in numbers. But it sounds like they have made real progress.

    Nathan banned. Surely not. Cant image why they would do that.
    Heres hoping anyway.

    What would you consider the best choice when you want to display a Flash video from a computer all the day on a big screen?

    In the first place, one wants something with a DVI-in I guess.

    I heard that Plasma screens can get damaged if they display a constant picture, is that true?

    I also read something about that in this topic with rear projection tv's getting burned. What's the story behind that?

    So what would be the best option?
    Is it correct to say that the display quality of LCD, Plasma and Projection of PC image doesn't differ much?
