Topic: flat panels life span

[Clondalkin]

Bro 40,000 x 20,000 is 800MP.

That was the quote said sir, di naman po natin pwede palitan or els they can sue me, he he he! But the good thing sir, your doing your math! Ha ha ha. Regards po.

Fyi lang po mga sir, 60,000hr or 100,000hr life is just for the panel half life, wich mean the brigtness of the panel will reduce half of its brigtness after that so called life span, and does not apply to the whole unit which mean any of given time, some other parts or componet of our beloved hdtv can also be malfunction, different type of electronics component also have its own life span! So 60,000hr life doest mean its for the whole hdtv! Regards po. Sana po makatulong.

Korek na korek po iyan sir.  Basta may quoted lifespan in hours, that refers to the half-life of the panel.

Talagang half-life ng panel ang tinutukoy na TV life, for 2 reasons:

1.  Pag ibang part ang nasira, papalitan mo yung part.  Pero pag yung panel ang nasira, hindi na praktikal palitan ang panel.

2.  Specs consider the half-life of a panel to be the life of the panel itself.  Kasi kung half-brightness na lang, e di para na ring patay yon.  

Hello po mga sirs, makisingit lng po. Wala po kayo kay lolo sharp ko! He he he. Quote: ULTRA DEFINITION: possibly the next wave of resolutions. Sharp has produced a prototype 64-inch Hdtv with a resolution of almost 9 megapixels. The 40,000x20,000 pixel resolution is over quadruple the current 2-megapixel standard of current technology. There's speculation that this technology might hit the commercial cycle sometime in the next five to ten years. Quote HD review issue3.

   Dun ako natawa sa lolo natin!  

May typo ang quote mo sir.  4,000 by 2,000 pixel yan, publicized in 2007 as Sharp's Ultra-Definition 4K x 2K, 64" 8.84MP LCD TV.


In fact, may post nga ako tungkol diyan in 2007:

There really is no such thing as "future proof".

1080p?  Ang baba naman ng resolution  ...   Wala yan sa lolo ko ...

Sharp already has a prototype 64" LCD with a native resolution of approx. 4000 x 2000 (8.8 megapixels)!




Sharp ultra-definition: Even higher definition

Kung mapapansin mo, binanggit ko na naman yung lolo ko ...  

6K pa rin ang highest resolution video master ...  for now.  And that's still higher than the Sharp Ultra Definition LCD's 4K panel resolution.

Hello po sir barister! Heto nga po recheck ko tong hd review magazine, may type eror nga po cya! May be po in neer future that hd content will also be available! Salute you all guys! Regards po.

I know that the 60,000 hours or 100,000 hours panel lifespans are just the quoted specs on the documents.

But before things get out of hand, I would like to know the actual experience of the owners based on their usage.

I have a relative who has a Samsung 32" LCD TV (I believe it's the older LA32 series with touch sensitive buttons at the side), whose LCD panel had developed a permanent vertical line in less than a year of its purchase. Luckily, the LCD panel was replaced by Samsung Phils. during the warranty period. It didn't reach 60,000 hours didn't it. Imagine, watching a movie with a permanent vertical line, if your unit is already out of warranty. Very annoying indeed.

Actually, the LCD Monitor of my PC also developed a vertical line just recently. It is a Samsung SyncMaster 740N which is just 3 years and 1 month old. Do note that the warranty for this LCD Monitor is 3 years on parts and 1 year on labor. The timing for it to fail just recently is very exact, just after the 3 years warranty period. It didn't reach the 60,000 hours life span either. Very annoying also.

I already am doubting that these panels do really reach 60,000 hours. I would also want to know whether plasma panels are more reliable. The older plasma models do tend to fade after a very long time (how many years?). Just like those I saw in Glorieta, Makati.

Don't you want to know which brand/type is more reliable?

here's an excerpt of my postings earlier this year;

       We have currently a total of 6pcs. 46" Samsung LCDTV (model LA46M51X/XTC) that are now a goner. It went kaput one by one upon reaching 2 years old..so an ave. of only 17,000+ hrs. continuous use. By the way though this screens were used as in continuous mode the power supplied to it is clean and regulated plus the room condition is at ideal 22degC all the time. No compounding dust or vibration issue on the said monitors.

Guess almost every brands have their own lemons and weaknesses...I was tasked nga to replaced all our monitors and initially they don't want again the Samsung...but..in the end..ang supplier availability pa rin ang nagdictate..We still end up with Samsung..this time the LB4650 FULL HD..2 units were installed..lets see after a year or so i'll update this thread again..bdway it was installed last June 14,2009 on a 24hr duty with clean/stabled pwer supply plus in a controlled 22degC environments.

Distinguish between failure rate and lifespan.

If the issue is reliability, you're talking about failure rate.  If the issue is lifespan, then that's the panel's half-life, or the time it takes for the panel's brightness to dim to 1/2 of its original brightness.  

A 60,000 hour rating refers to half-life, not failure-free life.  

Consumer Reports once rated Panasonic plasma as the most reliable flat panel TV, with a 2% repair rate.  Sony, Samsung, Toshiba, JVC and Pioneer also had low repair rates, at about 3%.  Philips was worse, but Hitachi was the worst.

Thank you Ceev for sharing with us your personal experiences on your LCD TVs.

Hi Barrister,
I apologize if my request is misleading.  It seems that you are more of an expert on these matters.

Since I was not able to find such topic in any of the threads here in PinoyDVD, I thought that I could ask it here instead. Do you think that it would be proper if I start a separate thread on this topic? I believe the proper topic for this should be "Share Your Experiences on the Reliability of Your LCD/Plasma TVs".

As I would be more interested in the actual usability of the unit as a consumer. Specially in a home theater environment (watching movies). I believe no one would like to be watching highdef movies with several annoying vertical lines on the screen.

Getting feedback from other owners would help us (new buyers) in deciding on what brand/type of flat panel TV to purchase. Since the big screens are more expensive, I would find it very hard to let go, should they develop problems just after the (usual 1 year) warranty period. If the problem requires replacement of the flat panel itself, which is almost the price of a new unit.

By the way, do you have any data on the failure rate of LGs? How about the Panasonic LCD TVs? I believe those estimates in Consumer Reports are quite low, as not everyone who had problems with their units do report to them.

I would really like to hear those who have their flat panel TVs the longest (in the no. of years/months).

Thank you for your clarification on this matter.

Yes, please.  That's a good idea for a very useful thread.

Nobody has any data on that subject for the local market, so I myself would be very interested in the replies.

I understand where you're coming from, and I do agree that independent failure/repair rate data is much more useful than half-life specs from the manufacturer.

Sorry, I don't have any data about LG.

The Consumer Reports data might be the most accurate data available, since it was based on approximately 93,000 TVs purchased between 2004 and 2007.

In fact, it might be the only existing data on the matter, since the only hits I get on a Google search are articles citing the Consumer Reports study.   Here's an example: http://marketnewsblog.blogspot.com/2007/11/first-ever-brand-repair-rates-for-flat.html

I only got news reports from other sources referencing the CR results, since you have to be a subscriber to access the actual CR article.

Posts on forums might give us overstated failure and repair rates, since forum posts are more often about complaints rather than praise.  Nevertheless, they will still give us some idea about which brands and models are more reliable than others.

JR,

What size you planning to get?  Let's take a look at the different models some time.

ey! already got a 50 inch plasma. im tempted by those 42 full HD models now but not in a hurry. good price bro! but its not for me



goin back to topic... yes i do think we should gather issues regarding our tvs and models and how long before the problem comes out.
