Life span of 5 yrs for LCD/LED!!! Reality or myth??/

[Hari Iyer]

Sony Stereo Amplifier Model - TA-AX44 - 28 yrs old and did not fail even once. Still using it and going strong with it.

Philips CRT HDTV -Model 29PT8836- 9 years and not failed even once. Still using.

Denon AV Receiver Model - AVR1604 - 10 years and not failed even once. Still using.

Moral of the Story - Old is gold. Never to be sold.

Sorry for the offtopic,

Sir, How is the TC-FX44 doing? Did you manage to fix it? I got an FX44 and 33 to restore. Do let me know if there is anything I should take care of while taking them apart.

Regards!

My 2008 make Samsung LCD works perfect till date!!!!

 

[darshanjoshi]

I had used Sony 21" CRT for about 30 yrs.
And my 46" Samsung 7 Series LED lasted 3 years after which they told panel is no more avaialble.

 

[Rockfella]

I wish I could bear with my 29 CRT TV but the size is just too big for my room. Considering all factors slim TV wins because they are so slim and occupy less space, look cool.

Really shocking, what did you do then, just forgot and bought another one???

not necessarily all the TV fail within 5 yrs, the problem being discussed is about the repair and its spares availability...

 

[diplomat]

TVS are comparitivly cheap now .. i find 5 year window is justifying

they are cheap, if you settle down to only companies like AOC, Sansui etc.
The premium series still enjoys the margin at a cost much higher than what they deserve

Built it obsolescence as someone pointed out is an issue, however AFAIK companies are supposed to provide spares till 10 yrs (I think). A friend's samsung plasma conked out after three years of use when it was no longer under warranty. As samsung did not have the spares for it, they took it back and gave my friend his money back minus the depreciation amount.

They are supposed to provide spares till 5 years from the date of purchase of product. Samsung follows the same. If they do not have the spares and are unable to fix the product they buyback the product on depreciated cost.I have gone through the process with Samsung.

5 year back you should have changed for lcd why??

one reason is health

CRT is unhealthy - the radiation is MORE harmful than LCD

Harmful Electrostress from Computers/Laptops

http://ergo.human.cornell.edu/pub/lcd_vs_crt_ah.pdf

CRT vs LCD monitor [EN]

One paper by respectable cornell univercity.

and normally radiations measured for 17 inch monitor - think of how much it will be for 29 inch screen ( twice the radiation as effective area is twice - 17 inch is ffective 16 inch monitor and 29 is actually 28 inch monitor)

also 42 inch LCD offers far bigger area ( more than twice ) to see - so more than quality it is better for eyes. better for brain especially you realize a lot of TV is now text heavy - news and investment channels.

BY the way I sold a load of LCD monitors replacing CRT when I worked in Jumbo Dubai , where health was a key focus point.

So maybe your 29 incher ( actually 28 incher ) philips TV appears good to you but really it is reallty affecting your and your familys health of eyes and body.

add to that added electrical consumption

is your perception "it is good" is so important over health issues??

Hi Hematwaghe,

I do not agree. TVs are actually quite costly now.

Most of times we end up buying features which we would not use and are forced to pay developmental costs of such features as part of the final price we pay for the TV.

Best example that I could think of is:

1) Smart TV. How many of FMs who buy it use it anyway? A good media player could do the same job much better and at a much cheaper rate.
2) I am sure given a choice between smart TV and FHD most people would choose FHD.
3) If so how come we find so many TV panels with "Smart TV" but not FHD?
4) What about MHL? Cant a good old wire do the same function?
5) Touch screen/swipe features?

I am sure if many of features could be stripped off an average panel, the final cost to consumers would be much less than what we end up paying?

I also find that companies are charging for features which most average buyer do not use. The point is these features are forced on to us as the companies can charge hidden premiums on these features. These features make good marketing material and to claim one upmanship. This only makes the average buyer confused and bewildered. Now a days u hardly find basic FHD TVs as they are bundled with either smart or 3D feature or both.

There should be basic televisions at various price points in different sizes so that consumers can make a choice but that would be going against the commercial interests of the companies.
No doubt advancement in technology should be welcome but that should take into account user needs and simplicity of use. Plus there is a big need to address the reliability aspect and the companies have to sort out very short built in obsolecence period.
If they do not do that then it would backfire on then in the long run.

Why I say TV prices are cheaper

1) 82 Asiad I remember Imported TVs were costing 18-19 K +Indians were around 15K
2) In 84 -85 my father bought Nelco Silver streak TV 20 ( effective 19 Inch) for Rs 7900 n NO REMOTE
3) In 2001we changed Nelco with TCL 25 Inches for Rs 16 or 17 K we got buyback of Rs 4k or 5K on nelco
4) Kabir Mulchandani of Baron ( Akai , Aiwa , TCL) was first who brought TV prices ( 21) around 10-12K mark in 1995-96 which was 15 K at that time
Till 1995-96 for many persons cost of TV was in MULTIPLES of monthly income , people used to save , and before Barons rise finance schemes were non exist,

(ref - http://archives.digitaltoday.in/businesstoday/22011999/invest.html
Ever since Baron entered the Indian CTV market on December 23, 1994, reviving the moribund Akai brand, prices have crashed. While a 21-inch CTV sold for nearly Rs 19,000 a set in 1992, it's easy to buy one now for less than Rs 13,000. Initially, Mulchandani dropped prices through attractive exchange offers: in 1995, he sold a brand-new CTV for as low as Rs 13,000-while the market-price was Rs 16,500-in exchange for old music systems and TVs. )


Also think of screen area you are getting earlier 21 inches ( which is effective 20 ) was gold standard , in fact first 29 were costing 25 K upwards ..SUBSTANTIAL SAVING IN THAT TIME
Now consider the effective area you get normally for CRT it is 1 inch less i.e 29 inchers give you 28 of diagonal areaCRT are 3:4 ratio and LCD are normally 16:9 ratio


Now see the areas

CRT Size Effective Size Area Sq. Inchs
20 19 173.28
21 20 192
29 28 376.32


LCD Size Area Sq. Inchs
32 437.44
40 683.50
42 753.56
50 1067.97



Now see the comparison


Comparison Times
32 LCD VS 21 CRT 2.52
32 LCD VS 29 CRT 1.16
40 LCD VS 29 CRT 1.82
42 LCD VS 29 CRT 2.00



So 32 Inch LCD if we compare even with yesteryear premium 29 inch CRT offers more area..

Now compare inflation and current earning levels 80s s gone a, so stop leaving in80s think what you were getting in 10000 in90s and how much time one used to slog to earn it. And consider price of same objects.
Think of electric consumption of CRT.

AND FINALLY THINK OF REAL ESTATE.

CRT requires a stand or cupboard.
On an average 29 inch crt occupies appx 7-9 sq feet of space.
In Goregaon conservative property rate is 15K / sq ft. SO a CRT occupies property of almost a lack or more.
LCD you can wall mount.


SO why you think it is overpriced?

 

[greenhorn]

Sir, I agree to your earlier points, but I'm a bit concerned about the repairablity of modern LCD's. The CRT (provided the picture tube was a good imported one) would last around 10 years or more, and only the circuit parts/LOT used to act up , and even those were quite repairable.

Well said Hemant.

But we also need to consider that the quality of products of those times were far better than today. CRT's harmful radiation - accepted too.

Technology changes and we have to move with the times. I accept that. However, does that mean that we have to put up with poor build quality? What about the sum of parts in today's TV?

Where are the good quality power supplies? The new ones go for a six with a slight power fluctuation. Take caps for example, Capacitors are so small that you have to look with a microscope to find one on the new TVs of today . What about the good ole Large Caps in older TVs that used to be present in all power supplies? I know the slim frame does not allow for larger caps but surely there must be ways to improve the quality of the caps?

The costly investment of the old days used to be a one time affair. Once you bought a TV, you forgot about it for the next 10-15 years at least. The newer pricing sends you in a dizzy, and god forbid if you have a servicing issue, then like they say in Urdu "Allah Malik".

Nowadays, you are considered lucky if your new shiny panel survives 2 years. Why such a drastic drop in quality? If quarter of the money you spent
on models advertising your products could be spent on improving product and build quality, what is the harm? Why not stand behind your products for at least 5 years? If the amount of money you spent cramming the product with a total gamut of useless features could be invested in better quality board, panels, parts etc then?

Just presenting the other side that is all.

Really very good information from hemantji and a very good 'other side' thought by vinodji. thank you guyz & others here for sharing your vast knowledge.

By the way, my question may seems silly but i'll ask anyway.
Can anybody post a link or source or something which shows the real the lifespan of these lcd/led tvs 3-5years, fact or myth? cause i couldn't get the one telling this exactly, all i got is peoples complaint who are having problems with their panels. anybody has any data like an xyz company produced/sold this much of tvs in these 5years and got complaint of panel failure or complete replacement, etc of tv in numbers against their production (ratio). or anyone can guess how much it could be? may be one thing is sure that compared to CRT failure of led/lcd could be more.

What my other thinking is IMO people shares negativity more than positive things in these kind of forums. for example if you are sitting between 9 out of 10 people are complaining abt failure of these tvs then you could think that might be true. but the fact is thats the half or partial truth.

The intention of the author of this thread is to educate ourselves with Real Facts and take a best decision during future purchase of who already purchased these new tvs. like hemantji & vinodji & other who did share there opinions with their detailed facts & figures will definitely help us.

Just one more 'other side' thought!

 

[Hari Iyer]

is your perception "it is good" is so important over health issues??

You said it - Its perception that CRT is harmful. We have more radiation through microwave and mobile towers than CRT tubes. The radiation in CRT is minscuile compared to radiation from any EMI source like a current transformer outside the apartment. Most of the radiation is prevented from the picturetube and the glass itself.

You will have to first do an apples to apples comparasion of my CRT HDTV and then comment on its PQ. No point discussing it otherwise.

Size as I said has its advantages - so you want to say that your 28 Inch TV being so good appears as big as 42 inch lcd? I was not knowing that?

also what about electrical consumption?

real estate saving ??

or it is soooooooooo good that it generates electricity giving it back to grid and creates negative space ( i do not know what negative space is !)???

Come home, we can discuss this.

 

[phasetard]

It wasn't uncommon for a quality CRT to last a lifetime. Ancient ones are still around today being give away for free.

Some ~20 years ago the first big screens started arriving and with it the push towards mindless consumerism. A salesmen at a reputable dealer told my parents then that they weren't made to last and he was breaking out into a cold sweat when he said it.

If you look into the situation of the vertical amplifier IC's for those big screens you can see they were cooled insufficiently and never made to last. Improved units came available from Toshiba, from more modern fab processes that made for a more efficient IC. They were discontinued, so you couldn't repair those old units.

That salesmen guy told us they assume you would want the next gen TV by the time those would fail. So it used to mean you would buy such an appliance/component at a considerable investment and the return on it was the quality built into it that would allow it to last for years or be serviced once it fails.

These days you can pick up a piece of junk big screen for a few hundred and you're lucky if it works out of the box when you get it home. Then you find out companies like Samsung are still use plagued capacitors many years later and you can get it repaired on warranty if you send that big screen back to some far off repair center yourself making it not worthwhile. But it's such a good deal that you can just go by another, and another, and another, and it's really just a lottery if it works or lasts at all.

That explains garbage like 3D tv's that can only fail on the market. They are running out of false standards and trinkets to bundle into it that might make you think you need to upgrade again six months later. Now we have the "smart" spy TV's which another hell altogether.

Caveat emptor, suckers.

BTW, it is worth noting that the cost of your mindless consumption is offloaded to you, the hapless consumer, every step of the way. There are environmental costs, for obvious landfill reasons, as they manufacture waste directly. In my country we're hit with surtaxes they call "green fees" or the like, which for monitors and TV's is a 25 dollar fee that covers shipping its carcass on a boat back to china to live amongst the children from whence it came. The funny thing is they never had a recycling program to collect them and put it on the boat... it's just another feel good fee but it's also offloading the environmental responsibility from the irresponsible manufacturer, while truly continuing to ignore the problem. That means you also get to live in the film from it. When you see pictures from china where they can't see through the air in front of their face? You get to breath that too. That is an integral component of mindless consumerism and you don't get to share in the profit it generates at all, even while all of the manufacturing is offshored so you don't even get the jobs, and it's ironic that the people who are making your big screen tv's can't even afford them themselves.
