99.9% pixel efffective on a Sony LCD.....

[admin_exported]

I dreaded the dead pixel problem in LCD PC displays, Dell say 3 dead pixels on a screen is not an excuse to swap for a new one.Others like Sumsung will replace even if there is only one.

On the Sony Manual for their Bravia 3 TV, it quotes the possiblity of dead pixels - but they say its normal.

I hope I have not got others to scan their large screens for dead pixels on top of the clouding and backlight issue, but just goes to show the quality control in place in the Sonys. Infact, I have never heard of dead pixels in a TV but on a typical TN or higher grade panel it is known to happen?

I heard that LED have a lower perfect yield than LCD, making them mass produced cheaply a problem!! You can buy a 32 inch Samsung 7 series LED for £782, how long before it can be sold for £500, they aren't selling as well as lcd at the moment. They may never be affordable?? Without a big player like Sony coming into the format en mass LED has much future as the Pioneer Kuro. Already the Koreans are working on thinner and alternative technology display.

Within the manufacturing process there is a tiny margin for faulty pixels for all manufacturers. It is quite normal.

As for the 'LED' sets they are still LCDs, just backlit (or, usually) edge lit using LEDs rather than flourescent lamps. Sony have two LED lit models - the 40ZX1, which is edge lit using clear LEDs, and the X4500 which is backlit using dynamic RGB LEDs. They haven't launched into LED lit screens en masse because they aren't as good as a conventional lamp-lit set. The 40W5500/5710 is a MUCH better performing set than the ZX1. The ZX1 is an exercise in technology (its also wireless), and being thin. The X4500 is another matter altogether and very much on a par with the Pioneer plasmas, but executing the technology properly costs a lot more money and the X-series sets are only available in 46 and 55 inch sizes at £3k+ and nearly £5k.

I think all maufacturers quote an acceptable pixel failure rate (per million), but before buying our Philips we made sure the shop knew that we would not accept any (why should you pay well over a grand for a flawed item). I would return the item as unused (careful with the unpacking and don't remove stickers).

Stuck sub-pixels are far worse. A dead pixel can be just black, but a stuck one will be 1 primary colour. My ASUS PC monitor had one stuck green sub-pixel when new, but I gently massaged it in a figure of 8 and it became unstuck no problem. Been fine since. Our Philips TV has no issue at all (and I think it is generally less common now anyway).

I wonder what the lifespan is of the LEDs in a backlight array? Can they be replaced individual or are they part of the panel?

Matthwepiano, It looks like then we aren't going to see LED lit Sony LCDS for the masses......for a long while?? Sony as a JAPAN PLC is suffering from market downturn, they aren't pulling in the dollars and the sterlings from US and Europe.

Thats bad news for the flatscreen industry.Looks like Sumsung,Sharp are the only LED game for the masses then??

In terms of the future its hard to know. Sony play their cards very close to their chest. I know there is a focus on developing 3D for next year and, of course, they are also entering the Freesat market. I think there is a chance some of the more expensive technology will start to trickle down but until Sony annouce future ranges all any of us can do is speculate. Mr Stringer seems to be very keen on consolidating the brand's position by pushing technological advancements (and quite rightly) so I'm quite confident there will be some interesting developments from the brand in the next year or so.

Matthew thats "sir" stringer to you and i.lol

Sony's LCD division is losing money and What HI Fi said Stringer is holding back LED en mass because of this issue. I think these Japanese firms are now planning by the day and not 10 years ahead. The Koreans will eat them for breakfast!

By the way Sony panels are deveoped with Samsung ......! Sony cannot make enough or perfect the yield

As for 3d TV, in two years time as Hollywood wants, oh just great, just throw out your W and Z series like a rock star that cost 2k in two years! Very ECO.

So what will happen to future 2D LED from Sony? Or is that business plan dead already?

More muddled thinking: no, we didn't report that Sony was holding back on LED-lit TVs; we reported it was delaying the launch of more OLED TVs. That's OLED TVs.

And yes, it's no secret that Sony has a joint venture with Samsung to produce LCD panels, but that's to do with economies of scale, not an inability to make enough or increase yield. As reported on this site in recent times, the company is also exploring other such JV manufacturing, both within and outside Japan.

3D TV is planned to be launched next year, but no one will need to throw out anything: the 3D movie releases will be back-compatible with existing TV/BD hardware.

I'm really not sure what all this Sony-bating is about, but it's getting rather wearing...

Yes, all rather strange.

I read Japanese having taught English there and learnt the langauge.I have done some business analyst there as a consultant.

There is no question that Sony along with other electronic firms are having problems with Exports and this is having a mighty knock on effect on their business strategy. The Japanese's biggest customers are not themselves but you guys. Their people were amongst the biggest savers but now that the Chinese have overtaken them.

As much as 7 out of 10 of the TVs produced are destined for the US and Europe.Unfortunately, the West is in so much debt that Scrappage scheme may have to be used to shift anything from Tvs to Walkmans! I do not recall Sony ever introducing a TV scrappage scheme....its unprecedented. One Sony Centre staff told me to bring in a TV that didn't work and get £50 back for a new Bravia.

I love flat panel and is disappointed that Sony is not trying to beat Sumsung at it.LED or OLED's benefits are great:-

1.Eco Friendly

2.Less power consumed

3.Greater perfomance if executed propertly....its still first generation. The state of the art OLED or LED could eclipe a Pioneer Plasma.Why not?

With Panasonic Plasmas they claim 100,000 hrs of use, LCD 60,000 hrs of use before the set needs a replacement.Sony ended its R and D on Plasma years ago to focus on LCD. They need to quicken the pace on OLEDs. The koreans are not standing back waiting for the Japanese to take the lead, they are now market leaders in flatscreen technolgies.

Why any company with a cliam to Green credential would not act on this now and still churn out very ECO unfriendly LCD backlight technology when something better is avalible astounds to me. At the moment the world is trying negotiate Carbon reductions and energy save.

Only with the very expensive Sony TV do we really get a Green ECO set.....not good enough I am afraid.

As for 3D Tv, frankly no one and I mean no one really known what will or will not happen in the next 5 years? I wouldn't even go down this road.Its pure speculation with nothing concrete.

Having lived in Japan, all I can say they are still considered weird by any standards,even the Chinese find them strange bunch.The Koreans are nearly as good in the electronics field and better in some specialist areas. More inpotantly,they have not been the most ECO friendly of advanced society. They may not have blazing coal fire stations like China[still developing] and import alot of energy but I have aways had an issue with their record on the enviroment.Its a 'throw away society' and nothing last. Except the Samuria sword, as it was good 400 years ago as it is now.

The bringing in of Howard Stringer was to many in the business company that all was not well with Sony's rather inward looking approach.I feel the OLED TV is caught up in the company's politics.

Sometimes (last night was a good example), you would be better off looking at a Samurai Sword on the wall than watching the dross being pumped to our dishes and aerials. They sure know how to make them without flaws.

Thats quite a first post FLATSCREEN - very similar in style and tone to the original poster.

Sonyse2t5's analysis didn't have the coherent to it, I have similar views as a business analyst, but its important to support your assertions.My rule of the thumb is never make a statement without any evidence.

The ECO arguement is a very inportant one, and LCD aren't very ECO friendly.I know about Panasonic and the company have aways layed cliams to any product it produces should be evaluated from the impact it has on the enviroment.Its a corporate code and mission statement they take seriously. They are considered much more ECO conscious than Sony.Panasonic's original founder's vision was as true then as it is now. And No I don't work for Panasonic.

The sooner the world moves to OLED and LED the better.Its not the be all and end all in Energy saving.But its not to be ignored. The power saving issue is real not hype.A lot of my insight comes from living in Japan as a 'foriegner' and not just reading about Japan from Western eyes.So I wouldn't expect everyone to agree

FLATSCREEN:A lot of my insight comes from living in Japan as a 'foriegner' and not just reading about Japan from Western eyes.

FLATSCREEN:Having lived in Japan, all I can say they are still considered weird by any standards

That's some serious insight you've gained there, feller...

FLATSCREEN:even the Chinese find them strange bunch

Yes, but then the Japanese do have a spot of previous in Chinese eyes...

I give you another two days before you are barred. Every post you start is about Sony being rubbish. Do you work for another, competitive brand?

I agree 100%. It's remarkable how popular his posts are.

Sonyse2t5,

Thank you for providing me with such a great source of entertainment at this incredibly late hour.

I have a feeling that there may be a possibility, albeit a very remote one, that you may, just may, still be slightly bitter at Sony over your tv debacle, and that this has, subconciously of course, influenced the content of your most recent posts, such that you are impeded from overlooking the company's faults and not only magnifying them to the extreme, but also attaching to them far greater importance than that which they must surely warrant, and in so doing you have reached a point at which you are precluded from rationally formulating anything other than a nonsensical argument based on your distorted judgement of Sony, which despite its flaws, remains one of the leading manufacturers of consumer electronics.

However, I too would be incredibly annoyed if having spent £5,000 on a tv, it had turned out to be c**p!
