had this set for 2 weeks now and all was fine and dandy, untill the weekend when it developed the green hue in the bottom left corner and a white patch in the top left, watched terminator 2 and it was quite noticeable, im gutted as this was a great tv!

also has anyone noticed an uneven line at the bottom of their picture on SD viewing?, as if the bottom of the screen is uneven?

Hi, Having just bought one of these sets from Comet (after reading the What HiFi review), I was disappointed when my less than 2 week old TV started developing lighter patches (on dark screens as described in this thread) at the corners as well. It is worst in the LHS corner near the on off switch.

I got this TV to partner my Blu Ray player and while it is great in all other respects I cannot help feeling that this problem is going to annoy me long term - I watch a great deal of Sci Fi films which tend to be very dark. Surely having paid all this money for a high quality TV the consumer can expect a product which is fit for purpose?

Do the patches all but dissapear once the TV has been on for an hour or so?

Hi All

The new TX37LZD80 arrived this afternoon and I have to say the picture is great. I have used the THX setup on Starwars Episode 3 to help set the colours and the colour look better than the LZD70. Black is blacker if that makes sense than the 70. I was a bit gutted at first as there was a clouding issue in the bottom right spreading into the bottom centre, however I persevered and after 4 hours or so it's gone. The actual screen size is the same but the set (including the trim) is narrower and in my view makes the TV look a lot better. Based on what I have seen so far, I am very happy with the set. Well recommended.

Hope this helps

I have had the LZD70 now for six weeks.

At first everything was fine, then the tell tale patches formed in all four corners.

I am absolutely furious with Panasonic, surely they must recognise that this is a problem which is affecting a batch of TVs, which are by no means cheap. Why haven't they recalled the batch?

I bought it from Dixons online, and will be contacting them forthwith to make them aware of my thoughts. To be honest, I love the TV, so was willing to take a replacement, but I have not heard of one single story where the problem is resolved on a second set.

Having stuck with Panasonic for years and never had any problems, I am gutted with this, in case you couldn't tell.

From what I have read it appears that you will be in for a long long search to find an LCD TV without light patches in the corners. Is it really a case of a bad batch or are they all like this??? Surely we cant all have got a bad batch TV? From what Duncan said it appears that even the LZD80 has this issue although it dissapears after a few hours.

The ultimate question is this: -

Are light patches in the corners of the scrren on a dark/blank screen a fault on the LZD70? Yes or No -

Surely someone on this forum can answer this question with either a yes or no.

Call me suspicious, but most of the retailers no longer sell this set, which was only out in November or so. Hardly out of date. It is not listed on the Panny site, whilst much older sets are, hmmm...

The problem with checking these sets is that you can't see the light patches until you are watching in the dark, and I mean at night, not just with the curtains drawn. When I was watching this at first, I was blown away by the picture quality, and that was only on SD Sky sources.

When it came to night time, that's when I began to notice the flaw. The fact that the light is always worst in the bottom left corner where the led power light is cannot be a coincidence. I have tried to leave the TV switched off for a while then put it back on but the shadow came back immediately.

When watching a widescreen source, the greyness is umissable in the left hand corner, I could just about live with the level at all three other corners.

Perhaps I am being pedantic, but when it comes to a TV, pic quality is by far and away the most important trait to me, which is why I have spent money on mains conditioners, quality cables etc.

In answer to the above question by rch19754, there do not appear to be any other posts complaining of backlight issues on sets other than the Panny. This leads me to the conclusion that this is indeed a bad batch. perhaps one of the WHF staff can get an answer from Panny, I'd be intrigued to know.

I am considering exchanging this set for the TH-37PX80.

Have just spoken with Dixons. Engineer will be taking the set away in the next two days to ascertain what the fault is arrange repair if possible. In honesty, I hope they can as I love the TV.

I doubt this will be possible given the other posts and the complexity of the issue, surely they'll just send it back to Panny?

Anyway, I will update when they have had a look at it.

I would also be intrigued to know what Panasonic had to say on this issue. Let me know how you get on with Dixons. I dont really want to swap as it is a great TV. Would have thought the WHF could answer yes or no to answer if light patches in the corners of an LCD TV on dark/blank input screens is considered normal. Perhaps they dont want to comit without actually seeing the set in the flesh.

I,ve had the same problem with the lzd70 . First set lasted two months without the fault.

Replacement set faulty after two days. Got issues with local store at moment and may need to get trading standards involved. I have emailed panasonic but response after waiting two weeks for a reply was not very impresive retold to contact my local store.

Set now been replaced with a loan set lzd80 while they determine the cause of the fault apperently first set not got any faults in the shop showroom. Luckily the second set they colected displayed the fault whilst the engineer was picking it up very noticible yellow glow in corners even in daylight.

Got my LZD70 back having been repaired by the TechGuys folk at Dixons.

I have to say, I was sceptical as to whether this could be repaired at all given the previous posts. To my amazement, it appears the set has been fixed! The ridiculous clouding has completely gone, I am now left with onyl the most miniscule loss of black detail in the bottom two corners, which my GF can't even detect!

I spoke with the technician, who told me that the screens had not been sealed as well as they should to the casing (shocking from such a reputable manfacturer). He advised me that this has only recently been discovered by Panasonic, which is the reason he new how to fix the problem.

I am off to watch Full HD in all it's glory - eventually!

PS If any further problems occur, I will be back posting in this subject without delay, watch this space.......

I am so glad you got the problem fixed and hope you can now enjoy your Tv without any further problems.

I wonder whether it is the panel not being sealed properly which is causing the yellow clouding on my Panasonic 32LXD700?
No chance of my local retailer sorting it even if this is the problem!!!

Well done on getting a result! I'm going to put up with mine as its only noticeable on very dark scenes. Hopefull it won't get any worse!
