Yes, the 65L9400U is on the list of competitors. The 55L7400U is not.

Sad for not including 55L7400 but performance should be similar.

Owning one now, I'd say the concern is overblown, as is the blue degradation concern. WOLED has compensation measures in place to make it moot. Granted, time will tell if the concern was warranted or not, but at the moment with panels that are less than a year old, it's just speculation.

The blue thing is real as the fragility and degradation of the panel. You have to constantly recalibrate the screen as the blue color degrades. Quite sad. People should always look for things that last as long as possible and not at things that you change every 3 months.

Maybe, maybe not. WOLED has aging compensation methods that keep the drift minimal through at least 20000 hours. Not the big deal you're making it out to be. Haven't seen much in the way of degradation over 400 hours. Hard to speak definitively about this one way or another until the problem reports arrive.

Why TVs no longer last 35 years but 20 000 hours ?

not paying that much for 20 000 hours.

Lol! Because after 7 years the tech is obsolete.

I have a 26 years old Panasonic CRT that looks damn good made in Japan. Even the sound is brilliant. Now everything is about replacing things with cheaper things to make the big corporations even more powerful.

I'm just speculating on the 20,000 hours. Hopefully, it's much closer to 30k (apparently the panel's actual lifetime). CRTs were built like tanks, sadly a bygone era when things were made to last.

"Hopefully" is not the same as an actual guarantee from the manufacturer. See how it behaves in 2 years.

I've seen some panels at panelook .com specified either at 30,000 or 50,000 hrs MTBF (mean time before failure ) with the criteria being ½ brightness . As for the rest of the set who knows?

Oldest panel in the house is a 2005 View sonic PC monitor (still working fine ) the other two PC monitors are 2010/2011 , 3 of the TV's are 2013 sets 2 are Sony and LG LED/LCD and one is A Sammie Plasma ,another is Toshiba 2012 CCFL /LCD with the oldest being a 2010 Dynex CCFL/LCD set all working fine with no warranty or other issues thus far.


My last 2 Sony CRT's (FD HD Trinitron and regular Trinitron ) lasted 13 and 14 yrs without issues they still worked fine when I replaced them with new sets ! I have a 14 yr. old Panasonic Technics 5.1 AVR that outlasted one Sony ES AVR and may outlast the newer replacement Sony ES AVR eek.gif
Never seen an LCD TV last 14yrs without repair yet .... I'm not counting on it either . If it should happen it would probably be a Panasonic ,Sony or Toshiba maybe Sharp.

ofc 14yrs ago you were talking Phillips and maybe Pioneer and Panasonic Plasma's ? maybe some FPTV /RPTV s ? or maybe a 15" LCD and ofc CRT's .

never claimed Otherwise, but I wouldn't complain much if it happened to show a little degradation at that point because the tech and its pq benefits are long overdo and nothing short of revolutionary

These prices are overinflated. Can you find it in shop right now ?

How many dimming zones does it have at 65" ?

I don't get it. Make them fix whatever they broke and get them to give you an extended warranty.

I think this may be harder than you think. The ZT60/65 were limited run displays that used a one of a kind panel specific to the ZT. It claimed a 98 color gamut and the filter was optically bonded to the glass.

In other words when it breaks you can't fix it.

98% color gamut of what ? Rec 709 ?

I tried but like the above poster said, there is no way to repair a broken ZT panel.  Apparently Panasonic didn't make replacement parts since they knew they were getting out of plasma.  SO ZT OWNERS BEWARE!

.
The filter is optically bonded to the panel itself. From my understanding it was the same method of applying the filter to the screen that Pioneer used on the Kuro displays which was suppose to be the ultimate ambient light filter.
It was sold as "Beyond reference level performance" with a DCI color gamut rating if 98%. Also added a "pure" red phosphor to the mix as well. Here is an article I found on the ZT.

Bingo. The fixing needs to be done under the same conditions found in Panasonic factory.

If you care about your money avoid OLED as it won't last more than 3 years at best.

 

Better go with that Sony LED. At least it can be fixed ! OLED panels you throw them away like the ZT.

Moreover you can estimate correctly the life of the LED inside the panels.

 

However since it has many dimming zones and many LEDs it will cost you a lot now to fix it.

However when it breaks the prices for LEDs will be half or even less compared to today.

 

Read it all : http://en.wikipedia.org/wiki/Light-emitting_diode

 

LEDs have a general life expectancy of 50 000 hrs.
If you use your lights for 10 hours a day, this should be 13.7 yrs.
For 16 hours (you sleep 8 from 24) = 8.56 years.
For 24 hours (you use it for cinema and sell tickets or as a public display) = 5.7 years.
 
And it can fail for various reasons. See wiki page.

Since they are going to throw away the ZT, should I take out the mother boards in the back and sell them as parts?

Of course. It will worth a lot in the coming years.

Take the whole defective set if you they let you.

 

You never know what part people will need.

Also try to find where was the original problem and where did they exactly break the television.

Panasonic no longer gives you warranty for the broken ZT.

 

But you will have a hint regarding what parts are still fully functional.
