...The plasma is potentially naffed, the screen started to go last Monday, lost picture just see black screen and varying coloured dots, but still has sound, so I am thinking it may be the gases but not sure, have no insurance on it, it is about 4 years old.................Anyone know about these type iof problems on plasma screens?
Incidentally have looked at new screens and plasma screens appear to be cheaper than the LCD screens now, but I would'nt buy another plasma screen would opt for LCD now.
-
A wise move.
Its actually rare that the 'gas' goes on the panel.
Its normaly the drive electronics and interconnect that die as these are very heavily stressed (and one of the key reasons why Plasma is to be avoided in the modern market)

Would that potentially be linked to the loss of picture ::)
-
Normaly results in lines on the screen etc.

Had one line about inch an a half from the bottom of the screen, had that since last May probably, so potentially a sign that it was on its way out ::)

Plasma pi$$es all over LCD, especially when you start going above 42" in screen size.
But anywhoo, english law gives you a 6 year window if you want to argue the toss with the retailer.
The "drive electronics" that someone else referred to is actually called a motherboard, and they can be obtained quite cheaply depending on the make/model.
The only other board you will find inside your set is a power supply.

Is it true that plasma TV's have a 'shelf life', the picture fades over a period of time ?

Well its a 42'' Philips matchline, if it is the motherboard :-/

Disagree with the plasma/LCD statement, thats not been the case ofr a few years now.
And the drive electronics I am referring to are within the screen section. These are the items that initiate the pre-charge, strike, charge and discharge cycles for the pixels. They consume huge amounts of power and run rather hot. I did a design review on a pioneer IC used in this application and the package was running at absolute maximum pwoer dissipation.....which is not good for longevity!
I would not even consider plasma these days as its stood still whilst the rest have equalled it.
LCD with the emerging LED technology (a few years of good) is the way to go
-

Viewing angles, response times and the inability to display a true black are just 3 limitations of LCD I can think of right now.
I definately agree that OLED is something else, unfortunately it's not really within the price range of the "average Joe" due to it being so new. Like all technology though, it will drop in price in a couple of years as it starts to get more popular.

Viewing angles are good, response times are fine and black levels good.
My TV Sony KDL46W4500
VERY GOOD TV

The W series Sonys started as Plasma worriers and are now Plasma beaters

178° viewing angle.....yup, that's pretty good.
4ms response time...Plasma's react in less than 1ms with ease.
Black levels on any LCD will never be spot on, because of the backlight.
It's all subjective anyway, because what looks good to one may quite well look like a pile of cack to another.
Audio systems are the same. My neighbour thinks our kit is terrible, and he came to that conclusion after accepting a £100 bet that I could generate enough bass in the living room to make him physically sick.
Give him his due though, he paid up once he was feeling better and his heart had found it's natural rhythm again ;D

I have to agree, LCD surpassed plasma many years ago in the viewable areas.
The one advantage (also disadvantage) plasma has over consumer LCDs is a glass front - LCD is prone to kids pointing too hard at the screen, and bigger kids losing grip on their Wii remotes ::)
The reliability of LCDs (except mine!!!) is way superior to plasma - how many of us are running 10yr old LCD monitors still, with no problems. Plasmas tend to start show degradation after 2yrs, and pretty 'dangle berries'ed after 4. And before everyone with older plasmas pipe up that theres is still as good as the day they bought it, it ain't, and I bet you said the same about your older CRT ;)

Response time is a plasma problem as well. It may be able to turn it on that quick, but the phosphur glow will have a fairly long decay time.
BTW, MDTM is also correct about the driver board, it invariably sits on the panel itself, sometimes detachable (thus available seperately), sometimes not (though everything is ultimately detachable ::)).

Real use black levels on Plasma are worse....due to the long half life of the phosphor (its stays in an emmitting state for upto 60 seconds after being struck) plus the LCD elements have come a long way to catch up.
So dont get fooled by that old cherry!
Plasmas take much longer than 1ms to get the pixels to the required state....there is a bg difference between reaction time and the point at when the pixel is stble.....again more bull from the plasma stable.

The problem with plasma it its actually burning out as your watching it
It it “literally on fire” remember plasma gets soo hot you can cut through steel underwater with it the screens on early plasmas got very hot
LCD has come along way recently it doesn’t degenerate the only problem here is the strip lights (usually 1 at the top & bottom) can go oc the drive inverters can fail too ….quite easy to fix if your in the know but not user serviceable
LED has amazing performance very thin although the future faults will be pixels missing LED’s are reliable but they aren’t when in their millions but im sure this will improve in time like everything else does….. Some LED displays can actually be rolled
Up like a roll of newspaper
But not in our budget at the moment (not mine anyway)
-
Brand wise I'm a big fan of "Samsung" think they make screens for other manufactures too but having got a 20" TV which is brill & have 22 lcd wide screen monitors, when we decide its time for the big TV to go (not yet our 32" sony big box is going strong) Also one of the main things about them is the gtees they offer & they are reliable or have been for us and if you look at them in stores first make sure you tune or get salesman to set it up right they often dont they always tune in best, the ones they want shut of ;D ;D making some look a poor pic , :y
-
I like LG a lot, got an LF66 42" LCD very good TV crystal clear too. Had no problems with it at all unlike the Plasma that we had before!
LCD is the way to go.
-
Got 2 LG LCDs in my room, fantastic monitors. both are 5ms response times, can play fast moving xbox games no worries 8-)

At 16.88 pence per unit for electricty over here :( I'll stick with LCD :y

Well I think I will replace rather than repair, and replace with an LCD screen, which one not sure yet as there are loads on the market and some reasonably priced dependig on what size screen you go for.
But I will be replacing it once I refurbed the living room, as I plan to take out the built in units, maybe chase the wiring into the walls, depending on whether I can find or build a reasonable rack for all my other components :y

Plasmas tend to start show degradation after 2yrs, and pretty 'dangle berries'ed after 4.
I sincerely hope Plasma's are 'dangle berries'ed after 4 years then, because our's came with a 5 year warranty as standard (our's being a direct replacement and upgrade from an LCD that failed 3 times in 7 months).

If the image quality is "'dangle berries'ed" after 4 years, that is known as "not fit for purpose" and english law covers that subject fairly well ;)

Perhaps you had better define your interpretation of "'dangle berries'ed" then.
My idea of "'dangle berries'ed" is no longer usable as far as any reasonable person is concerned, and most reasonable people would expect a television to last 5 years minimum.

Most TVs should last 5yrs, but thats not the same as it being anywhere near the same quality as when it was new. Being trained and qualified in TV repair, I can tell you that a CRT, for example, is right at the end of its useful life at 5yrs old - the phosphur is tired, and the vacuum was started to deminish. Plasma suffers similar problems (actually more so due to the extra complexity), if you can get the drivers to last that long.
The degradation in any crt tube, or plasma panel, is not covered by any warranty - its classed as fair wear and tear.

Sorry
The phosper doesent get tired hence CRT’s can be re gunned
A CRTwill go low on emmisions but this is caused by sooting around the guns in the neck other faults are heater cathode grid cathode shorts causing the display to go all green / red / blue other faults include shadowmask / degaussing & purity ….but the wors task of all was convergence East West probs …….goodbye CRT
Hello CRT

LOL....5 years was the life expectancy when I did the 224 almost 26 years ago...we've moved on a bit since then.

I've seen plasma's that are 6 years old alongside brand new sets (displaying the same test image), and while the colours in the 6 year old set aren't quite as sharp as the brand spanker, they certainly aren't "'dangle berries'ed" IMO.

I've seen old G11 look good after a few years. Bloody thing only ever used for an hour or 2 a week though ;D. That aside, I've also seen a trinitron screen last way beyond what it should, so you do get oddites that are unusual.
I really do hope your plasma lasts as long as you hope. But back to the matter in hand, LCD is superior in virtually all aspects, for home use there is no reason to ever pick plasma now.
And thats my last comment on this thread :)

I just hope we answerd Mike D's question thats what fourums are all about :y :y :y

I'm with KillerWatt on this one, large scale LCD is crap compared to plasma. my 4 year old LG is still rather brilliant compared to some recent LCDs.
And as an added bonus it keeps the room warm as well :y

Not without resoldering the frame timebase IC on a regular basis you didn't ;)

Trinitron tubes were way ahead of their time in the grand scheme of things.

I'm a bit of a gadget freak, so I have a tendancy to sell on long before the so called life expectancy comes about.
But back to the matter in hand, LCD is superior in virtually all aspects, for home use there is no reason to ever pick plasma now.
I can only speak from first hand experience.
We had the LCD, and all we got from that (aside from numerous breakdowns) was artifacts (pixelation) on dark scenes, shadowing between scenes, no such thing as true black (caused by backlight) and noticable (to me anyway) lag in fast moving imagery.
We now have the Plasma, and don't see any of the above.
Both sets are LG, and both got the best write ups for their class (so it's not like I originally bought $hit and then improved).
As I said elsewhere, what looks (or sounds) good to one won't necessarily look (or sound) good to another.....horses for courses.

Now Now ......the frame timebase IC on the G11 i remeber it well lots of silicone paste on the heatsink somtimes we used to socket the chip many a time the heatsinks used to fall off .......no were near as reliable as the 2 BD124's / BD131's in the G8 nor the PL508 in the G6
