Just had my replacement set delivered yesterday and have noticed 4 lighter patches in each of the corners on darker scenes. There also seems to be a slight buzzing sound for about an hour then the light patches almost disappear. Does anyone know if these 4 lighter patches are anything to worry about or will they get worse over time? At the moment I'm tempted to put up and shut up as sometimes it "better the devil you know".

I purchased one of these last week and have noticed slight clouding in 3 corners, and more noticeable clouding in the bottom left corner. Now that I have noticed it it is becoming quite annoying, particularly on darker or widescreen pictures or the xbox. Considering getting the set replaced, only worry is that the retailer insists I return it for inspection and if they don't find a fault I get the set returned and charged £95 for the privilege!
Philman - I assume your original set did not suffer from this problem? I have read threads where people appear to have similar issues but would like to be certain that this is not considered "normal" for the model before I return it.

Hi Sjkidd, I think its defintely a fault - its something to do with uneven panels I seem to remember reading. My original set didn't have this fault but unknown to me I returned the original thinking it was faulty but it seems there is a "quirk" with this set on Dynamic and Normal Picture modes regarding black levels. I am awaiting Dixons to contact me regarding when they can pick up my tv and only then after another week or so can I get the refund on the credit card. All in all its been a nightmare. The first tv was great though - its my own fault thinking there was a fault when really it was more a quirk in all of the sets.
I'm going to get a Sony KDL40D3500 40" Full HD 1080p digital LCD TV for £900 with a 5 year warranty from my local Sony dealer when I finally get the refund. Does anyone know anything about this tv? I'm worried about possible judder as some reviews have mentioned this.
My advice regarding your problem is to return the set. The clouding on mine seems to get slightly better the longer its left on but I'm worried what might happen a year or so down the line. I can't believe they charge £95 - who did you buy it from?

Hi Philman, thanks for the reply. I bought it from Digital Direct, the £95 apparently only applies if they cannot replicate the fault (£35 courier each way, and £25 administration), but I would much rather this was done in my presence! From what you have said and looking on other forums I am pretty convinced it is a fault and should therefore no have a problem. The clouding on mine also improves slightly the after an hour or so, but it is still noticeable and I share your concerns about long term problems. It is shame as otherwise the TV is excellent.
Going on the number of similar posts I have come across I think I might follow your lead and look into getting a different model.
Will let you know how it pans out.

Sorry you have this problem.
I have it on my 32LXD700 and got a replacement but it was worse.
I was told that some backlight bleed is normal and most people don't notice it. As you say it is a shame as it is a fantastic TV otherwise.
I am considering getting a Plasma instead as there is no backlight.

Since reading this post i have found myself sitting in the dark with the TV channel on AV2 (i.e. a blank screen - yes I am watching a blank screen in the dark!!) and have noticed that the TV does indeed have a lighter patch in all four corners - I cant say as I notice it when I am watching TV/films of playing x box but there is no doublr that it is there. Also it seems to get better once the set has been on a while.
Question therefore is - is this to be expectd of an LCD TV? Judging by the posts on this thread It would appear that it is. The only thing is that £700 is an awful lot of money to me and if I thought for one minute the TV had a fault I would be on the phone ASAP to get it replaced or get a refund.
Is this normal or should I ring and sort it?
Thanks

I'm still waiting on the refund from Dixons but when it comes through I'm going to get the set with a 5 year warranty even if it means paying a little extra. I still think the backlight clouding is a fault as my first tv never had this. If I were you I would get the replacement - I still can't discover if this is a problem that will get worse over time but in 5 years time I may be ready for an upgrade anyway!

I got mine from John Lewis - originally they price matched Empire Direct at 749.99 inc 5 yr warranty - I then found it at Sound and Vision online (they also have a retail outlet) for 695. Therefore ended up getting it for 695 inc 5yr warranty. I believe JL have now reduced the set to 799.
I am not so sure this is a fault. It is like a lighter patch in each corner but you can only really see it if you turn the lights off and put it on say AV2 or an input with no signal. We watched the Godfather 2 last night in the dark and there were lots of dark scenes - I have to say I didn't notice any clouding whatsover (and believe me I was looking!!).
Perhaps Claire or Andy could give an opinion on this - I understand that a bit of backlight leakage is par for the course with LCD and is a failing of the technology. If it affected my viewing or I could be sure it was a fault with the set I would definately get a replacement. Have had the set for 2 weeks now and ideally would want to make a decision on this within 28 days.
John Lewis have been excellent by the way

My TV is being collected on Wednesday to be taken for inspection. Still a bit concerned the I will be told it is normal but feel I have to take the risk. Would appreciate any opinions on what might be considered an acceptable level of backlight clouding though.
Rch19754, like you, in a dark room on a blank AV channel I can see clouding in all four corners. With the lights on the clouding in 3 of the corners does not have an affect during normal viewing. However, the patch in the bottom left is noticeable during dark scenes. Maybe I see it more because I know it is there but it seems pointless to pay so much for an HD TV and accept flaws in the picture, however small they may be.

I agree with you - if you can see it when watching dark scenes then it is unacceptable in my book. However I honestly think I would not have noticed this issue if I had not really looked for it.
I supose the key question is - is there a 37" LCD out there without this problem or this common?
Perhaps swapping for a Plasma is the only solution to this problem?

Plasma would certainly solve it, as there is no backlight (not to mention many other advantages,as detailed at length in other threads on the Forum).
However, we test TVs in both light and dark rooms, and with blank channels when we're changing sources, too, and we always note any backlight issues - and we've never found highly noticeable backlight bleed with any of the top-brand sets.
I think there are some dodgy sets around - maybe due to the sheer number being sold, there is a small percentage of defective ones, as with any products.
But I also think that maybe some peoples' expectations of LCDs are unrealistic. They're getting a lot better, but the very means by which they work still precludes true inky blacks.
We'll continue to tell you which are the best around - and the Pana is far better than many - but would again urge you to see the sets in action before you buy, as maybe no LCD will satisfy you.

I appreciate that the decision to buy is ultimately down to me (us). My only question is this: -
Is a light patch in each of the four corners of the set (when on a blank input screen) the same as backlight bleed?
Apologies to keep going on but I have only really seen one LCD TV in the dark and that is the one I have just bought!! It sounds to me like a fault free set should not have light patches in the corners regardless of the light levels.

I agree rch19754 - we should at least be receiving sets without patches in each of the 4 corners. If you have got the 5 year warranty I wouldn't bother sending it back as it probably isn't worth the hassle - especially if the problem decreases the longer the set is on.
Dixons turned up today and took my tv back - am now watching a 21" Sanyo...small but good picture considering it's over 15 years old. Hopefully won't be too long before I can buy the same Panny again from John Lewis as in my opinion its a better picture by miles compared to the Sony D3500 etc.
As I was comparing between the Panny and Sonys I couldn't notice any lighter patches in any of the 37" Panasonics in the showroom.

Hi All
I purchased this TV from John Lewis on Price Match from Empiredirect at £799 at the end of Feb. I am now on my 3 replacement set due to a green glow from the power LED leaching into the screen. The third set is now beginning to get this (it comes after a few days). I have been on the phone to John Lewis and they think a faulty batch is responsible for this and have recommended I look for a different Manufacturer/Model. I am aware that the TX-37LZD80 is due out within the next 30 days (according to Empire Direct) and wonder if it's worth waiting for that?
If not any other recommendations for a replacement set?
Cheers

I am off work at the mo so have spent a lot of time watching the TV and looking for the backlight bleed fault.
My conclusion is as follows: -
When I first turn the set on it has clouding/backlight bleed in all 4 corners. On a blank screen with no input this is very noticiable, however when watching a film with very dark scenes it almost undetectable although you can maybe see slight clouding in the very corners of very dark scenes (only if your really looking for it - i.e. on Pirates of the Carribean 2 which is a very dark film).
When the set has been on about an hour this dissapears - at this point there is no way you can notice it in normal viewing including x box/films etc. The backlight becomes totally even.
I have contemplated ringing JL to send it back but as it does not affect viewing I am gonna leave it. The set is too good all round to bother sending it back for something that only really happens if I sit in the dark watching a blank screen.
I can honeslty say that the clarity of both SD and HD pictures is superb. I will wait and see how this develops - as long as it does not affect viewing I am gonna leave it. I am looking at the blank screen now after the set has been on for 4hrs and I cant see any backlight bleed whatsoever.

Well I just received confirmation from Digital Direct that there is a fault with my TV and now need to contact them to discuss a replacement. As they don't have the Tx-37lzd70 in stock at the moment and, from what duncan100974 and others have said, there appears to be a bad batch around at the moment I might reluctantly look into getting a different model. A shame because I really do think it is an excellent TV but want to minimise the risk of a faulty replacement. Might hang on and pay the extra for the Tx-37lzd80, although would need to wait for a review first. http://whathifi.com/members/duncan100974.aspx
In the meantime back to watching the small but trusty CRT.

Hi sjkidd
I have just come back from going into my local John Lewis store and they are replacing my TX37LZD70 with the new TX37LZD80 model. I do not have to pay anything extra. It's coming on Friday morning, so if no reviews are around by then I'll try and let you guys know what it's like. Should be good though as they have modified it a little such as the contrast ratio improved to 10000:1 instead of 8500:1. It's also not as big as the speaker is mounted at the bottom of the set rather than the sides.

Duncan,
How bad was the backlight issue on your TX37LZD70? Mine has a glow in all 4 corners and it's now starting to annoy me. Watched a film today with loads of dark scenes and could see slightly lighter patches. I also bought my TV from JL - which store did you use? Have they not got any LZD70's left in stock at JL? Would be really interested to know how your new set performs. Thanks and good luck.

hi Rich
Did you ever get an answer to the query regarding a light patch in the corners of your tx37lzd70 - i.e. is this normal or backlight bleed?
I bought the same TV 3 weeks ago and it is fantastic......but, the bottom left and right has a lighter patch which is noticeable on, say, a null AV2 input, or on some dark scenes such as end titles on films. Under normal viewing conditions it isn't noticeable but I'm aware it is there and being a pefectionist it is a bit of an irritation.
I'm considering whether to report this, although my wife thinks I'm being a bit OTT!
thanks for your help

Hi
I actually have a green bleed into the screen from the LED in the bottom left of the screen. I too have noticed the lighting in the other corners. JL sent engineers out 1st time round and they concluded it was an issue and gave me an immediate replacement (they had it in the van). This time round they just took my word for it. JL didn't want me to have another set the same as I was on my 3rd and they suggested it could be a batch issue. They recommended that I choose another model but for the money I couldn't see anything else out there to touch the panny. I'd suggest you get in touch with Jl and ask them to send the engineers to check it out. There's nothing to lose. JL on there web site now have the LZD70 at 799 but instore it was still 999. The chap I spoke to was unaware that the LZD80 was out. It does get annoying when the buyer knows more than the stores that are supposed to provide excellent service and product knowledge.
All this is a bit annoying as at the same time as getting this set at the end of Feb I brought an Onkyo SR605 AV reciever and Kef 3005 se's and wanted kick ass TV/film experience!.

I have got in touch with JL and they are sending an Engineer out with a replacement set. However judging by the numerous people on this thread (and others) I am almost certain that the replacement set will be no different and am worried it might actually be worse. Wonder if the LZD80 will be better?

I wouldn't hold out too much hope for your third tv being glow free in the corners. Just got the third set (this time from House of Fraser after finally receiving refund from Dixons) and have got the familiar glow in each of the four corners. This time the top left corner is worse than the previous sets. I'm not going to get a replacement as this time I have a five year warranty and am pleased with the set apart from this glow issue.

Yeah I dont think I am going to bother. I have got a 5 yr warranty too. Will only get a replacement if it is new stock (i.e. 80 series). Clearly this must be a problem with the 70 series - still not sure if it affects all 70 series LCD's though
