Many problems Sony 46W4500

[Anonymous]

Clare Newsome:
Amita - he actually ordered it from Amazon in the end. It's just arrived and he hasn't unpacked it yet - think he wants me to be there when he does (plus he won't have an HD source for a couple of weeks, and I think he wants to do the 'whole new system' reveal). I'll let you know how he gets on - it may be the weekend until I get the chance to help out!

Cool, enjoy, I'll be interested to know how he gets on! Just to add a note of positivity to this thread, i've got the 40W4710 from JL - with the backlight turned up to max in a dark room, have luckily no sign of backlight bleed or clouding whether the set has been on for 5 minutes or 5 hours.

Im on this forum daily, and have followed this post from the start, I often wonder how many users are actually the same person, they are just trying to back up there own point and create a number of different user accounts to do so,, some high profile users may even employ this tactic,,, who knows,, but i THINK there is some of that going on here??

Ridiculous comment really, check out the many pics (including mine) on this site and others if you want to know the extent of the problem.

Sorry, im not disputing the problem at all, just putting it out there,,,

RE the photos of the backlight bleed! my 40w200 has had backlight bleed from new but in fairness is hardley ever noticable, But anyhow i took a photo of my tv last night for an experiment and found that the back light bleed looks much worse in the photo than in real life due to long exposure time my camara uses taking low light pictures. Im not for one minute saying that there isnt a problem as ive sufferd at the hands of sony myself a couple of years ago. Just being a pedant sorry
Im not saying there isnt an issue by the way just saying i think the photo exagerate it

Iïm on my second 40w4500 in 5 weeks, as I posted earlier, the first one got bad clouding and the second got it too, but not as bad. I have had the second one for 5 days now and in some way the clouding got smaller after a lot of use. But still some clouding when I watch movies, and yes I have calibrated the set with DVE and put backlight on 2. The other thing is, that it helps some more to put light sensor on, like sony says in their answer to the clouding problem. But if I put power saving on, as they also recommend, itïs ruin the picture quality too much. So not complete satisfied yet, but itïs helping. I dont care if their are clouding while no input, but if it spoils my movie with white clouds inside the dark or black scenes, itïs not acceptable. So I hope time is my friend (more use), now that sony is not.

My 40W4500 is strange, been playin Gears of War 2 for the last few hours and watched a HD DVD so its been on since about 3ish and no sign of the dreaded cloud. Im quite puzzled :|

Since only one person replied to my other post can i ask you guys which hdmi is best used with this TV? Do i need to spend £50-60 to get a good quality pic?

I don't see how splashing out on an expensive HDMI lead can improve picture quality at all.

With an analogue signal the quality of the lead, materials and connections are obviously paramount in getting a quality signal as it is susceptible to interference. HDMI carries a digital signal and therefore can't have this problem.

The crazy thing is when manufacturers start selling "high quality, gold plated" HDMI leads well above the price of regular leads when its passing a digital signal. There can't be any degrading of quality on a digital signal as it's binary - so it's either there or its not!

A digital signal is not susceptible to interference, only a break in transmission of data. Hence spending more than the basic price on an HDMI lead is a complete waste of money and a total take on by the manufacturers.

Something like a component (analogue) lead - go for it, the better the lead the better the quality but not HDMI.

Sorry, slightly off topic...

So how does the VDH flat hdmi win cable of the year? I understand binary is just 1 and 0 so if that doesnt get through then u wont have a picture.. but then WHF rate hdmi's all the time.

How do you guys test them? Is it blind testing as you dont know which hdmi is which and then you can see the difference? I brought a cheapy one from asda and connect my BDP S350 to my 40W4500 and upscaled Rambo dvd looks rubbish (the new Rambo film)! Am i doing something wrong?

Sorry to go off topic...

RE: "So how does the VDH flat hdmi win cable of the year?" - I ask myself the same question!

The net is littered with technical engineers and alike explaining how it makes no difference. Google it - there's loads of forums and tests carried out that back it up.

Once you break down the technology behind it, it becomes clear that the signal is either carried or it's not.

You don't get people in different areas recieving different quality freeview signals - some may have a weaker signal that causes a break in reception but the signal quality is the same, unlike analogue terrestrial. The comparison to digital TV really highlights the point.

I agree though - I find it hard how people can reiew one better than the other. I'm open to being prooved wrong if anyone can explain how this can technically work?!

I'd be interested to know too, my Sony DAV-DZ260 upscales to 1080p. It was fantastic for SD transformers but not so kind to my region 1 Akira. Apart from an annoying buzz coming from the top of the set I could not fault it. The only problem now is getting a refund from electrosaver so I can get a set that works.

Without getting into an argument about it, it's because digital signals are not as simple as just 0s and 1s. Digital data is composed of 0s and 1s, but these make up a larger framework which is susceptible to corruption and interference. If this is changed slightly, so is the signal received by the TV / amplifier.
Why is it that people have no issue believing that a different CD player can make a difference, but when it comes to a cable, it can't be possible? After all, if the argument is that "if it doesn't go through, you won't have a picture" holds with cables, why doesn't the argument that "if it doesn't come through from a CD player, you won't get sound" ever come up? Or from the Blu-Ray player itself? Surely there can't be any difference between Blu-Ray players since they all just transmit 0s and 1s...

Just to be on the safe side I bought a Sony HDMI to take advantage of the Bravia Sync funtion. I wasn't sure it would make a difference from my cheap £5 cable but I'm new to LCD. When I first tried it a message came up saying something about a lost signal. The TV then played sound through it's own speakers rather than my surround?. I retried this a few times before it behaved. Although now I need a new TV to start again as the buzzing fault has buggered things up.

Yes. And i'm certainly not getting into an off-topic argument, but different HDMIs do make a difference

OK Claire - I shall take your word for it! Apologies if I am wrong.

I would very much like a technical explanation for this though as in terms of digital technology and speaking to a friend who used to be technical sales manager for Pioneer, we can't make sene of this claim!

Perhaps another forum topic may be required?!

Hi, yeah i know what you mean about the camera making it look worse, thats why i took about 20 pics with various settings to try and get a true representation of my issue (btw on my pics the backlight is on MIN), some of the shots i got make it look way way worse than it acutually is. Never the less its still not acceptable and is very off putting in dark scenes.

With respect CD players sound differnt becouse there is a digital to analog convertion taking place with lcd/plamsa HDMI debate there no such issue.

Sorry - I don't want to hijack this thread, but by saying that, you are effectively saying therefore if you use the digital out on a CD player, then they are all the same...
I know this isn't true, I'm just trying to point out the illogical arguments some people use.

Far from it using different cd transports can give you a different sound becouse some are better at reading disks than others simple as, Have you ever had a marked CD that will play in one cd player but not in another?

Just to add this ongoing forum page (...& to repeat what I have just posted somewhere else...)

Anyone else wondering about this particular forum page....

Thw w4500 - everywhere rates it as an excellent tv...if you go to the shops and view it seems an excellent tv...BUT it seems that half a dozen new members (I am too!) have hijacked a forum page with repeat messages about something which could be faulty set!!...

A cynical person may think they had motives to increase Panasonic sales against those of Sony!?!?

A paranoid person could question whether there is only one unhappy customer with a few what hi-fi accounts and a few happy contented plasma owners contributing...

If we wanted to increase Panasonic sales we would return out W4500's had get a panny, but we are sticking to it in hope that the retailer will give us a better set.

Seems an excellent tv when you see it in the shops is different to actually having it inside your own home where you have time to inspect it in different lighting conditions and pick out any faults. You cant see clouding on display tv's cos they almost always have a very bright image on their screens.

If it were a faulty set would Sony not have said just go and return it, but instead they say that the problem is to do with LCD panels and to try different settings. If you look at the photos on this thread you can clearly see a few changed settings wont help! The case maybe that alot of W4500 are faulty and just a lucky few get away with a nice cloud free one.

Remember there are alot of people who are new to Flat screen TV's and will just go by what the retailer has told them rather then what is written in forums or reviews. Infact my local Currys was adament that the Samsung Plasmas are miles better than the new Pioneers.

When i asked about the W4500 they told me that the latest Sony was the W4000 and they had not even heard of the W4500. Alot of people buy from these kinda stores and if they buy a tv with clouds on their screen they just stick to it as they really dont know what to expect from their upgrade.

The Sony centre i got my tv from had a couple in who brought their tv a week before i did and were complaining about blockyness on SD channels.. the manager went on to explain that the tv's are designed to use a HD feed for crystal clear images..should this not have been explained on sale? He went on to suggest they upgrade to Sky HD if they want a better pic..the elderly couple didnt seem too happy.

So you see these threads arent here to persuade ppl to go to another brand but infact highlight any issues we have had with that particular series so that any one who wants to purchase something fully knows what they may be gettin themselves into.

Thanks Gareth - this is precisely the point I was trying to make - the signal isn't on or off - variations in the signal give it a different sound, so a better transport improves the sound as it gives a cleaner signal. Hence cleaner signal through the HDMI cable gives a better sound / picture. It's not simply it works or it doesn't as some people would try to make out (not insinuating anything about you here matey - you're just the only person that replied!).

Surley though you cant get a weaker digital signal? just one with less errors....Correct me please if im wrong but rather than 0&1's it's more like on and off going through a logic gate????? yes no?? And if a cheap cable wasnt shielded wouldnt it just pick uf RF which as far as i know wouldnt effect the digital signal! I mean those mains plug tcp/ip adaptors work through an absolute minefield of noise.

Am i talkin bo11£$%???
and anyway we are on the wrong thread prof ;-)
