RE: Week old 50GT50 Buzzing..!

I also noticed the dreaded DSE during the earlier football, I wasn't looking for it at all, but I did notice vertical bands about 10 inches in from the right hand side. It was a little distracting, but I didn't see the later game, so I can't say if it's still there.

I read somewhere that when you raise the contrast level, this reduces, if not removes the problem, though I 100% don't want to do that until the tv is fully run in. 

I noticed earlier on this thread that someone wasn't entirely happy with SD pictures,can I suggest that you lower the sharpness to about 25%, this improved images for me. 

I've also changed the Colour Balance to Cool, this looks better to me also, as I thought I could see a green tinge to certain images with it set to Normal.

I'm working away from Monday to Friday for the next few months on and off, so unless the tv takes a turn for the worse, I won't be changing it.

Well, I edited my post above, as I didn't want to seem like I was having a go at you, Nick.

To be honest, most people are not denying that we're experiencing problems. Rather, they're suggesting we get replacement sets. I may well go down this route. I'd really like to shake off this feeling of being underwhelmed. Perhaps I was expecting too much of the GT50.

 

Are you getting a picture like in my YouTube videos?

To be honest, it's difficult to tell. I just watched Earth's Orbit on BBC HD and it's the first time I grinned looking at the picture. However, just an hour earlier I was annoyed by mild DSE.

I think the aforementioned plan is the way to go. I'm happy to give the TV a chance to bed in, on the understanding that, if my niggles don't go away, I can get a replacement. I'll have a chat with John Lewis on Monday.

I probably need to watch a few more Blu-rays rather than judging the TV when fed ropey TV broadcasts.

RE: Week old 50GT50 Buzzing..!

The DSE was still there when I watched the football highlights last night, it's noticeable, a little distracting, but I can't work out why it's only on football, and always in the same place on the right hand side of the screen.  :?

I'm going to watch some cricket and rugby, and see if anything is there then.

Are you saying you are seeing a line down the screen?  To the right of it?  And you only see it on football?

RE: Week old 50GT50 Buzzing..!

Yeah, just with football, about 12 inches in from the right. Not a line as such, but a vertical darker/lighter banding, otherwise, the picture's great.

I would probably get it changed, because you are going to be watching a lot of football.

Have you definitely not got this gel?

I'm sticking with it for now for several reasons. I'm working away from tomorrow, so I don't want my wife to have to deal with it while I'm away. I've read that it lessons with higher contrast levels, so after the run in period, I will increase the contrast. Of course, if it's still distracting in a few months, I'll get it dealt with, but for now, it's not overly annoying, so I can deal with it.

Not on this one, no.  What I did have on the first one was a line going down the screen on football and that was on the right hand side, but I just presumed this was image retention from the Sky Sports new channel.  So I now never leave it on that channel for long or change the picture settings.  Second and third one are fine.

RE: Week old 50GT50 Buzzing..!

Hi guys. I'm going to keep my set regardless of the half an inch noise lines (only) SD channels. All other content is superb and that's just with factory settings. The set doesn't buzz like my last one. Blacks look really detailed. I don't want other issues by returning it for the sake of a slight issue. More so when I don't watch SD channels.

Have you tried the overscan feature?

Sounds like the same thing to me, and if your new set doesn't have the same issue, I will have to look at it in a few months if the increased contrast doesn't reduce or remove it.

If I was you I would change it now, John Lewis can get funny after the first month.

RE: Week old 50GT50 Buzzing..!

Now I've noticed the DSE while watching football, I can see it on more content.

BBB, just to clarify, you have just one darker line toward the right of the screen?

I can see several thin, lighter lines on the right of the screen that only appear with solid blocks of colour. When I can see them they're not glaringly obvious. However, my eyes are often drawn to right of the screen to check if they're there. I've done a lot of reading and quite a few owners report that they have gone through a number of sets, hoping to get a good one, and found that each replacement has noticeable DSE, typically on the right of the screen, though occasionally on the left as well. Some owners report that the problem lessens with time. Others say it stays the same. Others still say it gets worse. Some attribute the vertical lines to the AR filter bonding process. Others to the way the panel is driven. It's a mild problem, but it's there on my set.  

Likewise, the buzzing isn't constantly distracting, but it's always audible when the screen is bright and louder than on the two plasma TVs I previously owned. Again, it's a minor problem, but it's there.

Finally, I can't seem to get a picture where the colour balance looks right. On THX Cinema, supposedly the preset closest to D65, most of the colours look great, but skin tones look off. People either have an olive complexion, or look like David Dickinson. The Normal preset has an excess of green and magenta. When I watched the tennis highlights on the Olympics 2012 Blu-ray, images of the normally green centre court were skewed toward purple. On the Cinema preset, the magenta/green tint is even more pronounced. If I had to choose, the THX preset looks most accurate to my eyes, but without white balance or colour management controls, the picture's warm excesses can't be tamed.

I could probably live with one of these issues in isolation (I could get a professional calibration to address issues with colour balance, if not on the THX preset), but several small problems add up to a larger one. That said, I'm scared that the problems described above could be worse on a replacement.

 

It would be great if we could get our GT50s in the same room and compare aspects of performance. Of course we can't, but I've devised a few tests and questions for other owners in an effort to discern if the problems with my set are typical of performance more generally.

1) the DSE test. Most prominently with solid blocks of green (usually when watching sport) can you constantly see several slightly lighter lines on the right hand side of the display as you face it that become more pronounced with camera pans?

2) The buzzing test. This is an easy one. If you press the Guide button on the remote, does the TV buzz noticeably? The buzz on mine can be heard from 10' away (my normal seating position). It becomes louder after I press OK to pull up the full channel list. The buzz is also very noticeable during commercial breaks on 4HD, when the channel logo appears on a white background between advertisements.

3) The colour test. Does everyone look like they've spent too long on the sun on the THX preset? I've set the colour to four clicks below default (or 25 clicks from zero). Frankly, all colours are oversaturated at the default level.

I'd be very grateful if other owners could report back, as it might help me determine if the issues I've encountered are true of all GT50s (in which case I'm probably too fussy) or, alternatively, if I've got a duffer and it's worth going the replacement route. Endless swapping of televisions would be lot of hassle if every set has the same problems. Apologies for the mini-essay and many thanks.

I definitely have the same problem with DSE as you in exactly the same place on the screen. I haven't noticed it on anything but football though, but it is slightly distracting.

I don't use the internal tuners, only Sky, but I just flicked on to tv mode and pressed the guide button, no buzzing at all.

Colours can look a bit in your face, but I changed the Colour Balance from Normal to Cool, now looks good to me.
