That event did bring up an interesting comparison point between plama and LCD displays. I am pretty sure that if the unit had been an LCD, it would have been watchable (although cracked) until I replaced it but the cracked plasma display was just blank which meant my family had no TV to watch until I had a chance to get the replacement.

Since the buzzing in plasmas is at least partially related to altitude (high altitude means higher probability of buzz or worse buzz), I feel it necessary to report that I live at about 1000 feet above sea level.

The main source of PDP buzzing is substrate vibration (i.e - the glass). There is some evidence that the volume of buzzing is related to how secure the glass is bonded. A cracked panel obviously has glass that is able to move much more freely and thus vibrate with much greater amplitude.

Directional buzz is a hallmark sign of substrate vibratation. Essentially the glass is acting like a speaker emitting sound at the driving frequency. Is the Samsung PDP a 2-pane or 3-pane design? The old Pioneer PDPs () are 2-pane and also have the directional buzz.

So the verdict is what?....I guess the Samsung will have the best PQ & slight better black lvl?

I guess I'll go check out the buzz sound. How do you check it out in store?

You want to debate whether economic stimulus will improve the economy from here, we can drum up experts on each side who can speculate on the effect of government spending, tax cuts, monetary stimulus., etc. They would all be taking informed guesses on what will happen if policy A, B, or C is undertaken or not undertaken.

There is no such speculation required when I can walk up to any plasma ever built and hear the buzz when the display is operational.

I will not debate whether facts are facts here. Take that to the science-denying or hard-of-hearing communities.

(Note: I don't have any dog in the Samsung hunt one way or another. It is quite possible that Samsungs buzz louder than other plasmas or that some Samsungs do or that a particular model does. I have no opinion on that, having not bothered to form one.)

There is no difference in HDMI cables. If you can see the picture without visible dropouts or sparklies, the cable is working at 100%. No other cable will display a better version of that picture. You're simply wrong if you think there is a better digital cable than one that is already working.

If you hear a distracting buzz that interferes with your ability to enjoy the set, chances are it's busted. If not, get a different set.

Read occasional posts here that all plasmas have a buzzing sound. But have never heard it from my spring-'09 Panasonic TH-65VX100U [1st-page links]. Maybe it's silent because it's a pro model designed to run most of the day. There's no audible buzz even with a bright all-white image. Pressed my ear against the metal frame and couldn't hear a buzz. Also, with 6 fans, there's no fan noise even inches from the display--other than a brief whooshing sound at start up. -- John

Either the Samsung C8000 or the Panasonic VT25. Neither is a Kuro replacement though.

You mean a GT25/G20/G25/S2? Uh, negative. The VT series will only get you the black level and color accuracy of a 1st gen Kuro Elite. Kuro is a whole package, not just one part of PQ.

Or maybe you have hearing loss around the buzz frequency range of PDP tech. All, and I mean all, PDPs buzz to an extent because it is inherent to the technology. If you can't hear it, it is you not the display. Xrox has aready given you the reason why.

Speaking of the VX, will the newer models (VX200?) have the black level loss as well? Or is that unknown at this point?

I sorry, but if you cannot hear your VX100 buzz, its you because your display does buzz. You can't get around what is inherent to the technology.

I was hoping for a consensus. Ha, this seems like a bad time to be in the market for a new television but my Samsung LN52A650 just died on me yesterday. I'm looking into a possible out of warranty repair but I don't have a lot of confidence in that route. Now I find myself frantically researching the televisions currently on the market and no model seems to be rising above the rest.

Uh, negative. No PDP manufacturer has done that.

I've calibrated 2 VX100s (65" models) and both buzzed just like every other PDP. If you can' hear it, great. But that does not mean your display has overcome what exisits in the technology.

So does the Samsung buzz louder than the other PDPs?

It really depends on your enviroment and you being able to hear the buzz, some people are sensetive to it, I had myself in a room with a client and I could not hear it but he could

I have excellent hearing (which was recently tested by a doctor during an FAA exam) and my wife can attest that I am easily bothered by noise, yet I cannot hear any noise coming from my LG 50PK950 with the sound off. This set is silent for all practical purposes.

This was one reason why I went the LG.

Not really. However, PDPs that use a bonded color filter will buzz louder than PDPs that use a thrid layer of glass.

I think there is enough evidence to state that some Samsung plasmas (the thin ones?) buzz louder than normal. There have been members on this forum who have exchanged a loud buzzing Samsung with a VT25 or G25 and noticed less buzzing.

Fwiw, this is what CNET stated in the their PN50C8000 review...

"It's also worth noting that, unlike some readers, we didn't experience any unusual buzzing sound on our PN50C8000 review sample. It was quieter, all things being equal, than the Panasonic TC-P50G20, for example."


My understanding is that the VT25, G25 and Samsung 6,7,8k series all use a two-pane design.

I do empathize with those who perceive an abnoxious buzz coming off their displays. My 58" C7000 has a slight buzz I can hear if my head is oriented in the right place, but it's a non-issue from my viewing position.
