This is going to sound REALLY stupid, but how old are you guys? People in their teens and 20s are capable of hearing high pitched sounds that older people cannot. I for example can hear a high buzzing sound when my dad uses his camera, and I can always tell when our regular standard def tv is on for the same reason. The Wall Street Journal even reported several years ago how some stores in shopping malls were having these sounds emitted in front of their stores because they did not want teens loitering.

Not a silly question. My family was in town when my tv was less than a week old. I'm in my late twenties, my nieces are 12 and my parents are late fifties and my great aunt is 78 and I had both tv at my place ( I hadn't returned the first one yet)and everyone heard the noise. The sound coming from one of the TV was actually destracting while watching program.

What vendor did you get yours from, by the way? And did Samsung tell you anything worthwhile?

Yeah, I read somewhere that some teenagers use a high-pitch ring tone on their cell phones so they can hear it in class but the teachers cannot. Quite interesting.

Ugh... this is maddening. I recently bought an Olevia 26 inch set which looks terrific but channels are now freezing up on it (just purchased 2 days ago). Thought I'd return it for the Samsung, but now I learn this set has this high-pitched sound problem. Frustrating.

I, too, am now experiencing this same problem, and I purchased my Samsung through a vendor other than Amazon. I guess I'm going to have to return my set, although I absolutely love everything else about it. I haven't talked to the Samsung technicians, but I'll be calling them later today.

No, I didn't resolve it. I tried 3 different ones, and they all had the same noise. Let me know if you end up going with the same model from a different store, I'm interested to see whether this is a problem with Amazon's batch or the entire line. It's too bad everywhere else is so much more expensive than Amazon though...

Hi Kevin, I have experienced this noise. I bought it brand new and returned and exchanged it and the second television did this as well. You can read my comment on the comments page. Did you resolve this problem? CJ

Well this happened to me after about a year. It helps if you use it often. When it does it all you have to do is give the tv a light smack on the back and it usually fixes it for me

Yes, I have this model, and it makes the popping noises after it has been on for a short time. With mine, it goes away after the TV has been on for a while. It made them a few times after I turned it off as well.

I'm having the same type of noise problem with a 26" Samsung. It was like that straight out of the box. The backlight was set on 10 (in the Dynamic picture mode) I have to keep the backlight setting at 5 or below and then it's masked by the TV volume. On mute I can still hear it. Very annoying. I'll be contacting Samsung very soon.

This tv seems to be susceptible to electrical noise or so. i fixed it with a 3-prong adapter like this one http://rsk.imageg.net/graphics/product_images/pRS1C-2266744w345.jpg I installed in the tv electrical cable and now i don't see the pesky lines.

I have had my TV for 1 month now and have not noticed any of this. I would ask a Panasonic expert, but I can tell you that this is the BEST Plasma on the plant today and the colors are much better than any LED TV you could have purchased.

They only issue I've had with the TV is there are parts of the screen now but have no back lighting in the room showing certain colors come on the screen you can see a distortion not in the picture but the back light inside TV but I've had the TV for over 5 years and it does get used a lot I've had problems also with when I would change from ps3 back to the TV there would bea picture but no sound that has happened a few times for or had to do to rectify it was just turn the TV off and turn it back on again sorry I couldn't be more help I've never had this problem.

Mine too, after about a year. Seems to be common for this TV. Mine could not be cost effectively repaired.

At first I thought this was kind of a funny question...but then I went and picked up my backlight, and sure enough, when I tilted it back and forth it does sound like there is something very small inside that is moving! My BF says that it is the ballast and that it is perfectly normal.

I've had best buy out twice now. The first time to replace all the screws in the back of the tv and that helped for about 1 week and the buzzing or humming sound came back. Best buy came today and replace one of the boards on the tv and i'm hoping this will fix the problem.

Not all plasmas, I am not sure yet why but I have a similar issue too, did not care to check if it was a various coloured noise or just various shades. I DO NOT have it on my other Panasonic professional plasma though.Either it's HDMI cable or just HDMI connection )I use DVI on others - or this TV has more faults then I initially thought...The worse thing is greenish tint vs older pro plasmas which may not have this deep of the black level but are all more accurate in my opinion. I had 2 of these before and haven't noticed this issue just now - also if you display a window on a gray screen you can notice horizontal smudges at the hight of the window border.

I haven't had any problem with such noises.I still feel it's a great product, even though I have problems keeping it attached to a base because of its weight, and my swinging it around to fit my needs. Perhaps you need a new bulb. I use the standard bulb mostly because it gives off heat and warms the area around it.

I've had the TV for about 6 months. It is a bedroom TV so doesn't get a lot of use. So far I have encountered no issues but I do not like the sound quality.

Yes my tv's corners are bright. This tv is not worth the money. It also is not 120hz.

We've been experiencing it off and on for about 6 months. Two nights ago, it was really bad...today...its not there. It comes and goes. In our case its a blue stripe. We've seen it whether its coming from the cable box or bluray player. I haven't played with it too much, so I don't have a pattern of what it does and how to defeat it. I'd like a comment from Panasonic. Our TV was 5 years old at Christmas.

I have the same problem. I assumed it was caused by running the sound through a receiver. Does it do it using the tv speakers? I would like know too.

I just bought a new SONY KDL32EX523 and it has this too, except that the noise is loud enough on all backlight levels to be heard all the way down the hall! The sound absolutely would want to make me kill myself if I had to live with it every day. I'm just waiting for Amazon or Sony to get back to me otherwise this is going back.
