Have your say & ask the experts

This topic makes an interesting read. I find the number of models available from one manufacturer an absolute nightmare! I'm amazed that Sony quality control has not identified the problem and that they have not provided an adequate response to date. This cannot do their reputation any favours and I can understand why consumers will hold off purchasing a set if it is likely that an entire batch is faulty. The pictures of the set at the start of the topic look horrendous and I would certainly demand a replacement! I have a small screen Bravia which does not suffer from backlight bleed but has a very disappointing viewing angle and struggles to produce anything vaguely black...but of course this cannot be compared to a large screen set. Call me a 'stick in the mud' but i'll hang on to my Wega Trinitron for the moment...no backlight bleed, no clouding, no image blur, pure blacks, fantastic colours, excellent viewing angle...its not HD but hey i'd be watching primarily SD pics in any event...oh and its made in the UK ;) Yes i'm sure many of you will hate me for not embracing a (relatively) new (and flawed) technology ;) lol...Roll on OLED!

'Trinitron bleed'...sorry couldn't resist haha! (yes I know its not possible)

I can't comment on the issues some users are reporting here on the W-series sets but I would re-iterate to all the people who might be wavering in their decision to buy one that of all the ones we have sold we have not had one complaint from a customer about any aspect of the set's performance.

I  bought a 40w4500 and a sony 350 blu-ray 4 weeks ago and in daytime it was super great, but at night I had the same problem with a lot of clounding, like many others. Just read some of the very long thread about w4500 on http://www.another site/forums/lcd-televisions/807191-sony-w4500-series-100hz-50-000-1-dynamic-contrast-dlna.html. On page 191 I have posted some pictures from this evning, but you have to log in to see them.
I think  it´s very poor of sony to say it´s normal to have clouding, if it´s in such a scale that it effect the picture while you are watching movies. I know that every set can have a little clouding and that it´s best to have a little light in the room, when you watch lcd-tv, but I have calibrated my set and put backlight down to 2 and still it´s too much. So 4 days ago I was lucky to get my set returned and got another w4500. My hope was high, that this one was better with little or no clouding, but no, still too much clouding to accept. Some people on another site have experienced that their clouding would go away after a week or two (100 hours use), so I will give it a little more time, like the first one I had, because it´s really a very very nice set.
But why has Sony such a bad quality control and so poor customer service, that´s what I dont understand. W4500 is a great seller, but it will soon fall back on sony, if too many people get a bad apple and an arrogant reply.       

Hi I recently purchased the w4500 from Amazon made in Spain 10/08. I stumbled upon this forum while searching for information on these problems on the net. I used to have a 32" LG lcd which didn't exhibit any of these problems. So far I have noticed some backlight bleed in the corners when viewing head on, but the image degrades further when viewing from any sort of angle (refer image below). This only really applies during a black screen. I can't really fault the picture quality of this set. I watched 'into the blue' on blu ray and the image literally blew me away... that was until I got to the darker scenes.

While I was trying to set the picture settings, i noticed that on a black screen (such a one without any input), when you scale back brightness there is little improvement to the black levels below 50 (although when the room is well lit it looks close to). Has anyone else noticed this? has anyone tried calibrating using the THX optimiser? Can you see the shadow under the THX logo during the brightness calibration (I couldn't)?

I took a couple of pics with my phone cam (one in a dark room and two in a well lit room) which while quality wise aren't too impressive, you get the picture:

Even if it were law ,Ginder, the word stoic (in this case expensive with no gain) springs to mind.Please cite the relevant legislation. 

Its not a matter of "if it were law", it is the law and a product that costs hundreds of pounds and last just over 12 months is not a reasonable period of time.

As for the legislation please read up the Sale of Goods Act 1979. You have your full statutory rights under Civil Law to cover you, all you need to do is keep your receipt.

Back to the problem of the tv, the pics posted above look pretty bad, but could that be due to viewing angle? My tv clouds more when you look at it from a bigger angle, the only thing is LCDs dont have much of a viewing angle do they?

I am not sure that you have read this article yourself or you are cherry picking phrases to suit your interpretation however I shall pick out the bits which are relevant.

"• For up to six years after purchase (five years from discovery in Scotland) purchasers can demand damages (which a court would equate to the cost of a repair or replacement)."

This is a statute of limitation,not a warranty period.

and below this ,as explanation in frequently asked questions

Q3. Are all goods supposed to last six (or five) years?

No, that is the limit for bringing a court case in England and Wales (five years from the time of discovery in Scotland's case). An item only needs to last as long as it is reasonable to expect it to, taking into account all the factors. An oil filter would usually not last longer than a year but that would not mean it was unsatisfactory.

And then just to contradict your other statement:

"Q7. Do I have to produce a receipt to claim my rights?

No. In fact the trader doesn't have to give you a receipt in the first place so it would be unfair to say that you had to produce one. However, it might not be unreasonable for the shop to want some proof of purchase, so look to see if you have a cheque stub, bank statement, credit card slip etc., and this should be sufficient."

All the above in quotation marks are taken from the page you cited.Not sure how much plainer it can be.

 

The offical Sony statement, just in...

Statement: Sony BRAVIA KDL-46W4500 TV Clouding (Uniformity)

To achieve a high level of performance and picture clarity, Sony
utilizes a very bright backlight setting. This helps deliver the
brightest picture possible, as well as exceptional picture clarity even
with the darkest image sources.

However, under certain dark viewing conditions, the setting may cause
the screens on some of these televisions to exhibit a slight uneven
uniformity, especially for a blank screen with no video source. This
condition is not normally visible under typical viewing situations, such
as watching movies or television programs, and should not affect viewing
experience.

Should customers find that this condition affects their viewing
enjoyment; we suggest adjusting the following settings to minimize this
condition:

1) Setup Menu - select - Light Sensor: ON
2) Setup Menu - select - Power Saving: Low or High

3) Picture Menu -- Reduce the Backlight Level eg 'Standard' or 'Cinema
mode' (Factory Setting = 'MAX')

SONY has its own criteria for uneven uniformity which was created from
past experience that satisfies a high majority of our customers.
SONY believes the level of uneven uniformity is not defective and does
not plan to recall any of its products.

 

BWS:

any thoughts on the best of the rest anyone?

Panasonic 46PZ80 or 50PZ80 (4" bigger for only £1150). Great blacks,colours,contrast, motion handling, no gaming lag etc. etc.

Hmm……. So Sony are not actually admitting there is a fault. Which is what I said they would do. They are basically saying that if most people are happy with the TV then that is fine with them. They are claiming it is the way they set up their sets to get maximize brightness. They do not plan to recall any of their products. Which means anyone thinking of buying one of these TV’s should think long and hard before buying, because they will have problems getting anything done if they are not happy with their set.

As some one who prefers Plasma this obsession with brightness in LCD is just plain odd in my view. For my money, if you are buying a 46” plus TV plasma is the way to go.

Im a big fan of Sony products and love my 32D3000 set but this doesnt sound right to me.   Im looking for a bigger TV at the momment and thought the W4500 looked perfect.   This clouding problem only seem to exists on the 46 Inch models not the 40, as far as I can make out.

I think at the price Sony are asking for this set its not worth the risk at the momment.   Perhaps when the inevitable January sales are on - this set would be worth taking a chance but not right now.  

 

Yeah, this is the response I was dreading. I like how they say reduce the backlight even though with backlight on min you still get lovely big puddles in the corners when watching anything with letterbox bars in a dim room. This statement will probably make it nigh on impossible to get a refund/ switch the set.

 Kiss my a$$ Sony.

Its certainly looking that way to me but other 46" LCD models do not seem to have this issue.     The new Samsung sets are supposed to be excellent.

King of Kings:

No it happens on the 40" as well. I swapped my original one and the replacement did exactly the same. Once the screen gets up to temperature it must overheat and bleeds in the top corners. Its a design flaw rather than a technical fault.

I've been a silent watcher of the forum for the last week, prior to which I was ready to buy the 46W4500.

I've almost certainly decided against buying this set as a result of people's experiences, but I think it's only fair all those with the problems try out ALL 3 settings Sony have suggested and then post back with the results.

My gut feeling is probably the same as everyone else - the setting's won't miraculously solve the problem and probably won't even help it! There is however a chance, however slim, it may reduce the problem to a level which does not interfere with regular viewing, in which case, it may warrant the purchase. All the same - the proof is in the pudding as they say.

Very Annoyed:

Exactually what I have said a few times throughout this thread (even tho someone said my coments were of no help?)

I fail to understand why someone would choose a LCD over a Good Plasma set at these screen sizes then get the hump when the LCD does what it is designed to do. A LCD is backlit so there will allways be evidence of backlight bleed to some degree and IMHO this is far more apparant on larger screens as more light is needed to produce a even image. And as for viewing angles this is also a trait of how LCD's work. These problems were also apparant with old LCD Rear-Projection TV's. NONE OF THESE ISSUES AFFECT A PLASMA!

My advice is if you have these issues and are not happy with it, contact your retailer and either get a refund or exchange it for a Plasma.
