Official Panasonic GT50 Series Discussion Thread [No Street Price Talk] - Page 159

I have head this same story over and over. I have no idea why these techs insist that buzzing is normal for all PDP's when many / most have nearly no buzzing at all.

I guess it's normal for a tech to hear nothing but buzzing TV's since few people call them to repair a functional unit. My set makes nearly zero buzz. On a bright white screen when the power supply is being pushed hard, I can hear a faint buzz from 2 - 3 feet away in a quiet room with the audio off. Under normal viewing from my usual position it's dead quiet.

Unfortunately, no I don't believe buzzing subsides over time; you're stuck with the level of buzz the set has now. Having said that, buzzing is very normal in Plasmas when a high power draw occurs (e.g. during predominantly white/bright scenes). There are several technical documents from Panasonic and Pioneer (from when they made Kuros) that describe what causes it, and no it's not a loose screw somewhere although that has been on occasion the source of some form of buzzing.

I have yet to see a plasma that has zero buzz and I've seen a lot of PDPs. No everyone can hear the buzzing, as it varies with room environment, one's own hearing profile and it varies in strength and frequency which is why some people can't hear it. My wife for example, who has good hearing, cannot hear it unless she puts her head near or at the back of the panel. In my experience, normal buzzing should not be heard over audio from normal viewing position. If you can, then the set's buzzing is out of tolerance and should be looked at by a tech or have the set replaced.

This may not be the right thread, but, what 3d glasses are y'all using with your gt50?

The Panasonic glasses are preferred by most users. There are cheaper alternatives but aside from price, I haven't seen a single person suggest that anyone has a better alternative.

I use the ones tpollagi linked and their prices fluctuate like the wind it seems. They are very light and comfortable. The 3D on bluray is amazing. Youtube has some good stuff too. Cable 3D is just okay. I didn't plan on watching much 3D, but I've been pleasantly surprised.

I'm already on my 2nd that buzzes the same as the 1st. Regardless, I'm leaning on sending it back. Not sure if i'll get a replacement or just a refund. I keep hearing about panels that have no/minimal buzzing and also about multiple exchanges that all buzz. If I get a 3rd buzzer, then i think I'll just have to look elsewhere.
I would be perfectly happy with your set.
I am inclined to believe that there is a big variation in the buzzing level of different panels. Don't think it likely that all the various experiences with buzzing can be attributed to hearing differences. The question is, how much tolerance do I have for exchanges?

I just received my 55gt50 two days ago. Beautiful picture. In regards to buzzing. The only time I can hear it is if I put my ear to the back of the lower left corner of the TV. Its very faint. I wouldn't even have noticed if if I wasn't checking for it. I guess I got lucky.

You are correct, and hope you didn't assume otherwise from my post. I've said in my previous post that I went through 3 60GT50 that all had an abnormal amount of buzzing, and all three were returned. My last post was mostly dealing with the "normal" plasma buzz, which may or may not be heard due to various factors. Do remember that the buzzing I'm talking about is the one that's caused by high power draw, which is when the screen is displaying predominantly white or very bright scenes. That varies from set to set and from my own experience it should not be heard from normal viewing distance, over audio.

Thank you very much sir.

I have it set at the default it came with and have no more idea than that. I will check and get back to you in a private mail.

BB delivered my 65GT50 yesterday - April2012 date on the back. Thought I had a silent one until I tried the XBOX, then I started to hear some buzzing from 8 feet away. Every time I go to shut down the XBOX (hold center controller button down) that white pop-up box triggers the buzzing. Exchange delivery scheduled for Sunday.

Its still noticeable on bright white screen scenes.

I hear a little buzzing during intense light scenes if I am close to the TV and the volume is way down or muted. After reading others' experiences, I can't imagine exchanging my TV just over that. I think we all have to pick our battles when it comes to what we are going to be anal about...

I would be pleased if my GT50 operated the same as what you describe. However, on my panel it doesn't take an intense light scene for me to hear the buzzing from 10 - 15 feet away. Yes, the brighter the scene the louder the buzzing, so dark scense I cannot hear the buzz. I'm not being anal about the buzzing sound; there is no way this is acceptable for a TV to operate in this manner. As has been stated before, I believe there is a massive variation in the amount of buzzing that each panel exhibits. So far in the panel lottery I have been rewarded with two loud buzzers. A tech is coming next Friday to "service" my panel, but I'm not going to get my hopes up that he/she can do anything other than say "all PDPs buzz."

Good luck with it! I'll have to pay attention off and on to see if mine ever gets worse to the point I should get it warrantied while it's still covered.

When trying to stream content to the tv I find that the content is played back very choppy. Is this just mine or are others seeing the same? YouTube playback is also unwatchable.

Sounds like an internet provider/connection issue? Using the tv apps or streaming some other way?

My content plays fine over Netflix, Amazon, YouTube, and DLNA streaming with PS3 Media Server (the latest version of Plex appears to have Panny issues with pausing and fast forwarding starting the video from the beginning). I have mine hooked up over Ethernet, which I wouldn't doubt would result in better performance.

Tried to stream some music with the built in browser. Signed into mog.com but could never log on. I suspect the browser is just not compatible with mog.com.

I have uverse and using wifi

Anyone watched TRON Legacy in 3D? I believe this movie would be one of those movie where crosstalk could be a problem. I don't own a Blu-Ray player yet but that's on my list for 2013.

Like I wrote here a few months ago, I see crosstalk/ghosting with some pictures taken with both my Fujifilm REAL 3D W1/W3 cameras and even provided you a link to a picture exhibiting this for those who wanted to test it out.

Now I'm curious if I will have this problem with movies and I think I will because I watched a 3D movie for the 1st time 2 weeks ago, that was broadcasted, and I could see crosstalk sometimes. Unless Blu-Ray movies are different than broadcasted ones?

I have watched tangled and finding nemo in 3D so far ,Yeah i have kids ,both are amazing ..
Just got a plan with 3Dblu-ray rental and I'm waiting for Spider-man 3D ..Can't really say what the difference is between broadcast and disc are.I only watched a few 2D-3D converted broadcast(mostly football games) and they were just OK..
I will say normal blu-ray disc converted to 3D with the TV isn't all that bad though

That's kind of the way I feel, too. I hear buzzing on white scenes, but it isn't so disturbing that I would consider returning it. Some people may have different perceptions of how much buzzing is acceptable and how much is not.

With bluray (pana dmp-bdt220) you can choose 48Hz under the 24p setting in the TV settings menu. I like this setting on 3D only as it makes crosstalk virtually non-existent and I don't notice any flicker at all. On any other source (cable, internet apps, etc...) the 24p mode is usually grayed out so stuck with 60Hz and crosstalk. It's not bad though, certainly doable for the kid, he doesn't notice it. Youtube has some really good 3D stuff worth checking out

3d blu ray rental? What plan is this?

Today I received my bluetooth headphones. From Amazon I purchased a set of Creative WP-450's. At first I plugged them into my iPod Touch and paired them. Worked and played perfect. I then went into Setup on my GT50 and selected Bluetooth settings. Selected Bluetooth Devices and it quickly found my 450's. When I went to connect them it asked for a password. I entered 0000 as is a standard for many devices. It synced perfectly. The GT50 will mute its speakers and the master volume from the TV will change from just volume to Bluetooth volume. They sounded fine to my ears. No lip sync issues. Hope this helps anyone interested in using BT headphones.

People are getting crazy with returning this tv for buzzing. CRTs do it to especially when the screen has lots of white in it, which is almost never unless you are watching hockey or a movie that take place in the snow. It is the way plasmas are.

My panel has NO BUZZING. If I would have gotten one that had noticeable buzzing I would have returned it too. Whats the point of paying so much money for something that is defective. The fact that people like me have received buzzless sets tells you that it isn't normal.

Some panels buzz not only when there is lots of white but any time there is a bright scene, which happens all the time. And when the buzzing can be heard from 12 feet away, it can get very annoying.
