:)

It was kind of a UFO, but it's gone, and according to my wife, hasn't returned. JL will be bringing a replacement this Tuesday, so I'll be watching lots of football and rugby this weekend to see if the dse is still there.I'm still undecided what to do, the picture looks great on the whole, just that little problem.How are you getting on with your replacement GT and Yammy Strapped?

RE: Panasonic TX-P50GT50 Plasma TV - Vertical Banding

Hi BBB,

I just posted on this exact issue on your thread about the Yamaha 1020, then spotted your post here.

After a week's viewing, I'm convinced the dirty screen effect is exactly the same as on my first set. Annoying, isn't it...

Rather than enjoying then new TV, I feel I'm simply waiting for vertical bands to appear on content, which inevitably they do. I've read threads elsewhere where users state they see the vertical bands one percent of the time. If this were true of the sets I've owned, I wouldn't consider it a problem. Occasionally there are programmes where I can't see it at all. On most content, however, the dirty screen effect will rear its head at some point. And of course if I watch sport I can see the bands most of the time.

I've no idea what to do. I think it's very unlikely that another replacement would be free of this issue. However, there isn't another model I'd want either. The more I think about it, the more I'm convinced that I'll have to settle for a TV with a distracting fault. Alternative models have problems that would annoy me more.

Beyond that, I might speak to John Lewis about 60 series Panasonics. That'd mean getting a refund on my GT50, living without a TV for a couple of months, and hoping that Panasonic have done a better job this year. Sounds like a lot of hassle. And each generation of Panasonic plasma has nasty surprises for owners. I think the sad truth is that there's no such thing as an excellent TV any more. The market dictates that production costs are consistently pushed down, making compromises with performance inevitable.

 

On a more positive note, I'll be keeping the Yammy (see comments on 1020 thread).

RE: Panasonic TX-P50GT50 Plasma TV - Vertical Banding

I've just looked up, and the dreaded yellow marks are back. <img src=" />

Well, this one's definitely going back now, 

I've just worked it out, you were right. We have a patio door, which lets a band of light through the side of the curtain, and this manifest itself as yellow marks on the screen. As soon as you block the light, the yellow disaapears, then, let the light through, yellow is back.

You'll have the same problem with a replacement, then.

The good news is that this can be fixed. I'll see if I can track down the thread where I read about this and post a link. You should definitely contact Panasonic.

RE: Panasonic TX-P50GT50 Plasma TV - Vertical Banding

Well, I've managed to block the light source, by taping the curtain to a unused curtain hook on the wall.

Do you think it's still worth contacting Panasonic?

This isn't where I first read about the "light through the back of the panel" issue, but if you scroll to the bottom of the page you can read Panasonic's response to emails about the dirty screen effect and the problem you're experiencing.

Seems this can only be rectified by sending the TV to a service centre, though. Frown

I guess that depends on how happy you are to leave the curtain taped to a hook. I might accept that as a temporary fix, but I'd find the taped curtain almost as distracting as the yellow blobs. I'm guessing your wife won't approve of that as a long term solution either.

Sorry to hear you're having further headaches. We really shouldn't have to put up with all this after spending a four figure sum on a new television.

It's not noticeable, as I have Ikea Lack units either side of the tv unit, with records and my front speakers on, and this blocks the edge of the curtain that is taped. I could also move these Ikea units back a touch, this blocks the light too, but is not so pleasing on the eye.

Shoopin time, maybe RS too.

Ignore the "scroll to the bottom of the page" comment. Panasonic's response is actually near the end of the first post. The rest of the thread may be worth a read, but I'm guessing there'll be no surprises in there.

RE: Panasonic TX-P50GT50 Plasma TV - Vertical Banding

Interesting Strapped. Looks like the vertical line on that guys ST is far worse than my GT, mine is much less noticeable than that.

And judging by Panasonic's response, there's nothing they are willing to do about it. It's nonsense to suggest (like they do) that all Plasmas are made this way, I can say with 100% certainty, my Kuro didn't have this problem.

My mind is almost certainly made up, I'm sticking with this one. Will ring JL tomorrow, and cancel the replacement.

One question, what do they mean by running slides of different white and grey fullscreen images? 

Do they mean the scrolling bar?

RE: Panasonic TX-P50GT50 Plasma TV - Vertical Banding

Sounds like the dirty screen effect on your GT50 is toward the more tolerable end of the spectrum. Now you've identified the cause of the yellow blobs and found a workaround, I can understand your decision to stick rather than twist. 

By running slides, they're not talking about the scrolling bar, rather a sequence of slides designed to break the panel in evenly. You could reasonably argue that using a new plasma TV responsibly is just as effective. Besides, I'm guessing you're past the "panic" stage, as your set has been in use for a month.

I'm intrigued to know, do you think the dirty screen effect has become less noticeable as your GT50 has bedded in?

I'd say the issue on my GT50 is pretty comparable with the photograph uploaded to that thread.

I'm watching the football and I always see the dirty screen effect with camera pans. There are a couple of lighter lines, roughly an inch thick, about three inches from the right-side bezel. It's frustrating, as I think the picture is fantastic otherwise.

If I thought things would improve, I could live with the problem short-term. I've been watching BBC HD tonight and the picture was fantastic the majority of the time. I was mostly watching documentaries, though, with lots of static shots.

Yeesh! Every year it seems there's a new problem with Panasonic's *cough* award-winning TVs: SD motion issues, fading blacks, vertical thin green line in the centre of the screen, etc, and now the fault mentioned in this thread. Impressive  ohhh sure

Indeed, rather strange.... should have bought a Samsung guys...... like mine, Samsung PN51E6500.... tremendous blacks and no weird things happening on the screen.... cheaper too.

 

Hope everything goes well though with you guys's tv's and all becomes well.
