When a plasma dies...

post #1 of 14
Thread Starter 
Hi everybody,

I'm new to this flat display thing, and looking to buy my first set (probably a Panasonic G10 series).

The shop warranty is zero pixel faults for 2 years, but I wonder:
If the plasma panel lives with no faults for 2 years, how likely is it that a cell dies after this?

I know a TV will eventually die, but the specified plasma life makes this a theoretical issue. Technology will have moved on before the panel fades.

To sum up: Is it likely that cells die "every now and then", or is it more like hard disk drives - either they fail within a month or they'll last very long?

I've heard of some pixels on Pioneers going out after 6 months but I'm hoping this is a very rare occurrence.

Quick question for you, what shop is it that provides a zero pixel fault for 2 years? Best Buy's $400 EW is not even that liberal.

My 6 year old pioneer 433cmx has never had a problem.The power supply was changed by pioneer in my house for free a few years ago because of a reported line failure but it always worked fine for me.No pixels dead when I bought it and no pixels dead after 6 years.

If your shop provide pixel perfect warranty, you should definitely take advantage of it regardless of brands and models. In a 1080p flat screen (PDP or LCD), there are over 2 million pixels and most manufacturers only consider panel defect if 0.001% are dead or stuck. 0.001% sounds very good but that's over 21 pixels are dead or stuck.

However, dead pixels are fairly rare and they almost always show up immediately within the first 100 hours I believe. Also, most plasma are rated more than 60,000 hours and with the G10, I believe it is rated 100,000 hours for half bright. Think about it, if you watch your plasma 24 hours a day, it will still take over 6.8 years for it to reach 60,000 hours.

It's the local, authorized dealer ("Panasonic Center") here in Denmark, Europe.


Thanks for the feedback from you guys. It makes me feel a little more confident sbout buying a plasma.

We've seen two screens we like. One is the Panny 42G10, the other is the Sony 40Z4500. I know the sony is LCD, but it's a decent picture.
I have more trust (knowledte?) in a LCD, but the Sony is 50% more expensive here, so it's hard to justify.

Any thoughts?

Plasma is still better technology produces a better picture quality and will last a long time. if you watch 8 hrs a day x 365 thats not even 3,000 hrs. a tv last 60000 hours which is 20 yrs so im sure you will get a better tv.

I know you didnt ask how long the tv last but rather if dead pixels occur that is an issue that cannot be avoided regardless if its lcd or plasma technology.

Thanks, gus,

My thought is: I know that both panel types can suffer from panel errors from the beginning (although I get a zero-pixel-error guarantee, so it's not my concern), but what I don't know is:

Are pixel errors very likely to occur along the way? Should I expect that pixel errors pop up over the (first couple of) years, or would that really be a very old age issue (like fading), unless they show from the start?

All input is welcome

Or, maybe what happened to me just half an hour ago may happen.

We have a th50px77u that we purchased in September of 2007. Tonight, it suddenly made a clicking sound and the bottom half of the screen now only displays a mish mash of colors (mostly red/pink) and no picture. The top half looks as good as it ever did.

I have another Panny plasma that I'm now concerned about. F*** Panasonic.

I have a Mack warranty. We'll see what happens.

Hi G.U.,

Thanks for sharing your "experience" with us.

However, that sounds more like a controler or panel supply failure than a dead pixel.

I wouldn't mind hearing how your warranty claim turns out.

I can get some extended warranty (which I really consider) on mine if I buy, and seemingly there are a few international insurance companies that control this. In my case, it's a UK based insurance company represented by the local Panasonic Center.

Its ineablte dead pixels can occur at any given time, you can have a whole month without dead pixel and out of nowhere it can pop out.

as far as reliablity panasonic has the most reliable tvs out there, its not common but like the last user usualy some come of PSU or mainboard has an issue, but its a few in the pack while on the other hand like VIZIO is pos samsung is better but not as good as panasonic in terms of reliablity and customer serivce.

Lg is worse then samsung towards TIR and pioneer is on top of everyone with reliablity , performance quality.

common issues? single glass panel the way its made to give the best PQ it comes with a sacrifise, best picture quality , and SOME claim a degree of buzzing at certain angles. then theirs other related issues that do go away as you break in the tv more with usuage.

Bottom line: all tvs have their flaws regardless if its 1k or 5k get what you are looking for

Picture Quality

Reliablity

Customer satisfaction.

hope this helps let me know if you have more questions.

I'll report back when I find out how the warranty thing turns out. It appears like a panel supply failure to me as well. In fact, it's almost certainly the SD Board (TXNSD1HMTU) - Scan out (Lower) according to the Panasonic Troubleshooting document.

I know that the general consensus is not to buy extended warranties, but on an expensive purchase, it's probably worth the cost. At the time, I paid about $1700 for the TV. The warranty was $120 if I recall correctly. Maybe it will have turned out to be worth it.

Regardless, I'd go Plasma over LCD any day. We have both and the Plasma is just provides a better picture. The LCD just seems too unrealistically colorful, even after calibrating it. But, it's two years old now. Maybe the newer ones are better.

Forget the colors they still have not fixed issues with lcd, plasma is always the way to go no point in lcd over plasma as it can also be more expensive, only reason why i see someone needs an lcd is

need smaller then 42"

or live in a house that is celling glass or a "glass" house
