Damn. I've only had this TV for a day and already got the DirecTV logo burned into the top right corner of the screen. It's not like I left it on the guide and fell asleep. It was burned in by just browsing the guide and looking for something to watch. I thought it was IR but after two hours of running break in slides I can still see it.

Patience will be rewarded.
I hope so, because I like the set otherwise, as I said. It doesn't help that I have my LCD laptop in front of my surfing the web while watching/breaking-in my TV, and seeing these bright white webpages as a source of comparison.

So I just got this set, this is my first new TV in 6-7 years and I'm coming from a 34" XBR970 Sony CRT (love it to death). Everything about this TV is great except some posterization I'm seeing in gradient patterns, there's a clear separation/banding of colors that's really distracting from the image and is a huge minus for the PQ of the set.

I'm experiencing it both on my PS3 and my HTPC, I'm wondering if it's a matter of using the proper color depth. Any suggestions? I was told that "all" of the supposed 24,xxx levels of gradiation are only available on Cinema mode, does anyone know if there's any truth to this? I'm currently using THX Cinema mode, is it possible that I'm only using half of the levels of gradiation which accounts for the lack of fluid color blending?

Would the VT50 be any better in this regard? Lovely TV otherwise, I understand this is a bit of a limitation of current PDP technology but I'm surprised to find there isn't more discussion surrounding this..

... ..

On some content I have noticed the same false contouring. The tv has the ability to display a smooth gradient when it's fed a smooth gradient but on compressed video, the video processor doesn't smooth out the gradient; it just displays it.

I don't think it has anything to do with the shades of gradation. It's a weakness of the Panasonic processor in these TV's. It has been pointed out here numerous times as well as with many other PDP's.

In some cases I know it's the video signal because I can see the exact same effect on my older Samsung LCD. I'm sure that some settings will make the effect look more pronounced but I don't think any of the settings will make it go away.

It's not burn in. It's image retention and once you start watching moving images it will disappear. If for some reason it does not. Simply run full screen channels for 24 hours with no static images and it should be gone. What settings do you have your TV set to. Generally i set it to Contrast, Brightness to 30 and Sharpness to 0 and Warm 2 for the first 200 hours using the Custom setting. I then raise it and take it easy for the next 200 hours restricting my watching of movies with black bars and static images to less than 25% of my viewing time. After I hit 400 hours I freely use my set and never look back i never notice image retention or any sort of stuck imagery after this and I've never had the problem with either my 65VT30 or my 55GT50 so clearly I am doing something right.

Well I just received my replacement 55" GT50 since the first one exhibited what I believe to be excessive buzzing. It turns out that my replacement buzzes exactly the same as the first one. My first TV had a build date of April 2012; the new one was built October 2012 and has the -2 suffix on the model number. Again, the buzzing is very audible from 10+ feet away when the bright images are displayed. I'm disappointed, and I guess I'm not hopeful that I can find any satisfaction.

I had called Panasonic regarding the buzzing on the first unit, and they simply told me to exchange it for a new one. I suppose I could try calling the "Viera Concierge" service again and insist they send a tech out to look at it. I guess I want to know if the level of buzzing is considered "normal" operation. If so, then I think I'll return the TV to Amazon, get a refund, and find a different brand/model because the buzzing is distracting.

For those who experience little to no buzzing...how far is your TV from the wall? I'm wondering if the buzz is reflecting off the wall back to the viewing area. My TV is about one foot from the wall, sitting on its stand on a media console. I am also going to try a different power strip, just to see if that is introducing any issues.
post #4597 of 9717
My tv has 0 buzz. Mine is mounted on the wall with a slim Mount. You must have a deffective unit again because I can put my ear next to it and I won't hear a thing.

Is this still true on a mostly white scene?
post #4599 of 9717
I also have no buzz--I need to put my ear near the back of the TV to hear a very faint buzz. It is on its stand about 18 inches from the wall.

I have not paid attention regarding white screens. My experience is with normal viewing TV programs and Blu-ray and DVD.
post #4600 of 9717
When I get home I will try out a white screen and let you know the result. I have a 60gt50.

Reciever/external speakers help:

On my 65GT50 I'm trying to hook up my Denon receiver to use with the external speakers. It's an older Denon, no HDMI, just the red/white outputs. I'm connecting the outs with the adapter that's provided and connecting the adapter to the back of the tv. I turn on the receiver, hit the video button, but nothing. I know the speakers are connected because the tuner (am/fm) works fine. Is there a setting on the tv that I'm forgetting? Thanks for any help you can provide!!!
post #4602 of 9717
Go to sound on the tv menu and and choose external speakers. Or does your reciever have an optical slot?
post #4603 of 9717
that adapter red/white is an audio input isn't it?
you need to connect the output from your set top box to the input on the receiver, assuming you're using a stb.

No optical slot.

When I go to the sound menu, and turn the tv speakers off, it greys everything else out, but I can't get any sound of of the external speakers. So odd, maybe it's just time to upgrade my receiver.

You're right. I'm a moron. It's working perfectly now. Thanks for your help. I totally forgot about the DVR box.

I've had my GT50 for about a week now and I must say that the picture is a step up from my LG 5600. Having said that I have a question for you GT owners. The build date of my set is April. Obviously there has been firmware up-dates since then. Do these up-dates have any effect on PQ???
post #4607 of 9717
Not sure what's really bad about the browser. Seems okay to me, it's just not what I would use daily but it works and just recently I discovered it plays flash videos. That had to be from a firmware update, it couldn't do that when I first bought my GT50. You know you can use your iOS or Android device (if you have one) and download the Panasonic app? It has the keyboard on your portable device. You can look directly at your iOS/Android device and type everything you need then press send and it transfers to the TV so you don't have to look at the TV constantly to verify your input as you would using the remote or your Bluetooth keyboard.

No. Any Firmware updates that you can download via Viera Connect are only to update the apps on the TV - they never pertain to or affect picture quality.

Got my 65gt50 hooked up today, good Lord! Love it, PQ is stunning and it's a huge upgrade over my '08 Panasonic TH-50PZ85U. I mean wow. Inky'est blacks I've laid eyes on.

Using cnet's settings tweaked to my tastes, black ops are a little hot I believe, at least right now. I'm used to a very dim picture best for night time viewing so maybe that is part of it.

Watching TV zoomed no logos or bars for a week. It still looks fantastic.

3D via native bluray is actually brilliant although that's not what I got it for.

Zero, nada, zilch buzz....so far. Maybe it's my "rock concerted out" ears or my age....

<1080p sources are really not that bad. Doable. Comcast.

My Android phone and the vierra remote app = super geek cool factor! Throw my vids, pics, music, files, w/e to the TV with a flick of my finger.

Thank you Randy for the light dim and rt angle monoprice hdmi connector suggestions, I'm using both with pleasure!

Man ,,AGAIN!!
That really stinks ..I feel for ya..I mean seriously though,,what the heck are the chances of this??
I'd be upset too..I actually tried listening for the buzz earlier ,,very faint ,but did hear it only when my head was right next to it..Mine is also wall mounted ,roughly an inch away from the wall.

Kinda weird but the toslink out is only stereo. I have my PS3 going in and I have the toslink out going to my turtle beach headphones and the indicator doesn't show the 5.1 DD being passed through. That kind of defeats the purpose of a digital audio out. So now I have invested in splitter and separate cables.

Is the optical digital out from the TV itself? If the audio from a TV program or a Blu-ray/DVD player is 5.1 it should be 5.1 from the TV optical output. I listen to my TV using stereo headphones and I was cautioned to use a Gefen TV Digital Audio DecoderGTV-DD-2-AA because that model is able to convert TOSLINK 5.1 Dolby Digital ouput to stereo whereas the less expensive Gefen model cannot handle 5.1 audio. But I am not familiar with using PS3.

Search earlier in this thread... the optical out on the TV only outputs DD or DTS 5.1 for sources that originate within the TV, like Netflix and other internet apps. Something to do with licensing issues I believe I read...

You need to connect the PS3, DVR's, Bluray Players, etc. directly to the audio receiver.

I do think your eyes will adjust. But if it bothers you now, try using Warm 1 or Normal (rather than Warm 2) as a color temp while watching or playing hockey. I would use Warm 2 for everything else.

It is amazing how our perception has so much to do with it. After watching this TV with proper settings (C-Net/Black Ops) for a few months, when I see other peoples TV's now, I notice how bad they look and how innacurate the colors are compared to the my GT50. My wife even picks up on it now! Most people seem to like an image that is way to bright, and washed out with over saturated colors. IMO the way it looks on my GT50 is the way it would look in real life, and isn't that the point, to have as realistic a picture as possible?

Before I got my 5.1 headphones I was using the Cables to Go 28733 digital to analog converter. But the Turtle Beach 5.1 DD headphones are much, much better than my Ultrasone HFI 780's when it comes to simulating 5.1. And those Ultrasones have "Natural Surround Plus", a simulated surround from stereo input.

Thanks and I guess that is it. Its not that expensive, but more of a pain. I found a 3 way manual selector and then decided to add my satellite receiver so I found a 4 way (PS3, XBox, TV and now Sat Box) for $26 with shipping. When my wife saw the 3 way she said, "I don't even want to know", lol. At least the cost of Toslink cables has dropped dramatically in the past 10 years. You would think they were made of gold back then.

Thanks for the TV sympathy!! After spending a little more time with it, I actually think this second unit buzzes a bit louder than my first one.

I was also thinking, "what are the chances of this!?" Unless, of course, the buzzing is "normal" and for whatever reason my room setup is amplifying the buzz. But based on what I'm reading here, most of you can only hear the faint buzz when standing right next to the TV, which is absolutely not my experience. My wife has suggested we try putting something on the wall behind the TV to dampen the buzz, but I don't think that's a long-term solution.

Time to call Panasonic again and get them out to take a look at it. I'm not sure I want to go through the whole exchange process again as it takes a week, and I need to make time to be home for the delivery, yadda yadda.

I had the same problem (made the same mistake). I assumed the Red White audio cables can connect to that adapter that plugs into the back of the GT50. But as mentioned, after closer inspection that is INPUT not output for audio. Have not seen a set without RCA connector Audio out in the past. But luckily I did have an optical input on my bose speakers...so all is well. But I will admit I was "trouble shooting" it for an hour or so before I got smart enough to closely look at the label on the input ports.

So just go into the Advanced Setup menu and turn Viera Connect Banners off. Not a big deal.

I'm in the same boat as you, except I've got an ST model. Exchanged the first for what I found annoying buzzing (pretty much what you described in your earlier post) only to get a panel that buzzes the same. Again, mostly not noticeable but when there is a transition from a darker to brighter scene and there is low volume sound, I can hear the buzzing from 12 feet away. Annoying to say the least. The fact that so many are reporting no or minimal buzzing is what makes my quest for a quiet set still worth pursuing. Some posters in the ST thread suggested that I should just ignore the buzzing given that it's not noticeable most of the time but to me it's bothersome, especially in those darker-to-brighter transitions. And I also thought to myself, what are the odds of getting two defective TVs, from two different build dates that have the same defect? Maybe this is normal and some people just don't hear it. But just to remove some individual hearing variations, both my wife and daughter can hear the buzzing, although neither of them is bothered by it as much as me.

I'm going to call Panasonic tomorrow and hope to arrange for a tech to come and see if there's anything that can be done about my unit. I hate exchanging big TVs, it's such a hassle, and given that I've got two panels that buzz exactly the same, I'm not so sure the 3rd will be quieter.
