Basically, been bugging my parents to buy a new tv for ages. We just had a crappy like 28" inch old style big deep television in our living room. Piece of crap. it sometimes switches itself off and all sorts.

So went to comet today to have a look for a tv. Originally was just gonna get a 32 inch, but somehow managed to convince them they'd benefit from the 37 inch haha...

Ended up looking at all of them and the best quality one we saw was this Panasonic 37 inch one. Really high contrast ratio, HD, etc Picture on it seemed sooo crisp, especially compared to most of the other LCD ones.

This tv had a sign on the price thing saying 'LCD 37 1080 hd etc etc' bla bla... Despite this it had signs next to it saying 'Winner of best plasma award 2007 etc etc' - I said to this bloke 'This says it's a plasma? - but up there it says LCD' ... he was like 'yeh it's LCD - ignore that'

So we were like we'll have this one, it's so much crisper / depth in colours compared to the others in the shop... Got to the 'paying for it moment' - and the bloke threw it up on the computer and the computer screen said 37 inch plasma!

I said 'hang on that says plasma... He said 'yup it's a plasma' clown.

Thing is, only thing I've ever heard about Plasma tv's is that they have a short life span. So was a bit at the thought of getting a Plasma, especially considering I hear most LCD's can do similar quality these days.

That said, we looked around the store again and couldn't find anything that came close to the picture on this one we had wanted.

So just bought it! - got it home and it takes up a large corner of the room but it's ace, can't believe how good it looks even on freeview! DVD's look ace, haven't tried Xbox yet - and obviously haven't got blue ray or anything to check it out - but going by everything else we're all at it.

The only question I have is, did we make a mistake getting a Plasma tv? is it shit? - how long realisticly last with average use? I've heard about 'image burn' from logo's or static things on the screen, how long will that take to actually burn into the image.

Cheers,

ok, i didnt even know theymade 37inch plasmas... thought 42inch was the smallest? anyway.

screenburn or image retention happens when you play games and leave it paused etc, most sets have like a feature which moves the picture ever so slightly so its not sat in one spot consistently, also most have a "whitewash" function which flushes the pixels IF you get it (does not always solve it)

life span is usually worked out in hours, for LG where i work they used to say plasmas have a life expectancy of around 60,000 hours, this isnt guranteed though, after that time the pciture brightness would expect to be half as bright (i.e useless) , gases in the set are not able to be replaced.

its a personal preference as plasmas can be better at displaying blacker images... however the main thing people want nowadays is LCD's for crisper images etc.

well done. panasonic plasmas are brilliant screens mate. i want the 37" as well! you probably got the PX70 at a guess. its not 1080, only the LCD one is, but id still take the plasma over that model. definitely got the best sound on those as well

Yeh i get the idea of leaving a game on pause or just leaving it on a static image burning that image on the screen,

but what about logo's on the screen?

like for example the 'DAVE' or '+4' or E4' in the corner etc? They just sit there while you are watching the program? Will they burn - how long will they take?

or if the logo's are slightly semi transparent (they look like you can slightly see colour under them) - does this solve the problem as the pixels will change colour slightly?

Have you checked the model number on the net to see if it is plasma?

a couple of other advantages of lcd over plasma, lcd has a wider viewing angle, and produces brighter pictures in well lit rooms, plasmas do have better contrast though

alot of channels now actually move the logo on the screen. again tv's move the picture ever so slightly so its not constantly burning the same pixels (you cannot see this movement to the naked eye) but yea logos on screen can cause screenburn. we get it alot

Plasma TV response times are still better than LCD. Most of the decent new ones are < 3ms...

Good choice on the TV though. The only reason I went for an LCD at the time was because Plasmas of the era used 4:3 resolutions stretched to a 16:9 screen (not great if you want to view a PC desktop on it). As yours is 1080p this isn't an issue.

plasma tv's have lamps, they are rated anything between 30,000 to 60,000 hours, and thats measured in half life, ie how long it takes for the lamp to reach half its original brightness, that if its rear projection of course

Steve LCD's have back lights - with liquid crystals that block the light in different ways.

plasma has gases, which when electronically charged turns to a plasma and emits light.

Product Life-span Plasma TVs have a reported half life of 30,000 to 60,000 hours. Half-life is the time it takes the lamp to fade to half its original brightness. LCD TVs also have replaceable backlights, but the expense of replacing one when the time comes may be greater than simply replacing the entire TV. Both Plasma and LCD technology should more than adequately satisfy most consumers. The average CRT TV (the kind most of us have at home) has a half-life of around 25,000 hours. If the average American household watches an average of four to six hours of television a day, even a 30,000 hour lamp would give you over 16 years of use. By then you'll be enjoying your new 'Holodeck.'
