The fans on my VT60 are also always on, and they sound like they are always running at the same speed.

OK, I do have to admit that they boot up at a higher speed followed by a slight cycling down (but I have not noticed any change in speed otherwise).

I commented a while back that the fans speed up considerably when you're in the service menu. But other than that mine are always on when the tv is on and they always run at a constant rate.

I can hear my fans when the content is quiet but the noise the fans make could not be described as a howl or refrigerator-like by any stretch of the imagination. That's the reason I believe some units are worse than others.

I'm sorry to hear you didn't get what you were looking for.

Thanks for the kind words. Two of them are definitely from the same batch. Their production numbers differ only by 2 units: 5352 and 5354. However, the first unit was in 06xx, but again, from the same store/warehouse. So, it should have been shipped along the others.

Actually I went back to BB last night and showed them pictures of the dented pedestal. They said they'll replace it again. I asked if I can wait until they get new shipment, and they said yes, we can order now but set the delivery date to one month from now until the current units' stock ran out or something. I think it is a very good offer. By mid-August, maybe I get a unit from another batch.

The fan noise is being investigate over on the AVForum. See post 470. So far they claim it is a combination of back panel design and environment.

I say they are right on the target. My noise is quite similar but a tad less in high pitch and a little more on the bass.

Oh, and the pulsation frequency is different on mine.
post #1718 of 11493
Yeah the pulsing on mine was more noticeable then that as well.

What a shame if all these is caused by a stupid back panel design that could have been solved easily in testing stages. Unfortunately for us, if it is the back panel, I don't see any bright future in fixing the issue from Panasonic. You know designing and distributing the back panel in post production basis is very expensive. They probably address this in VT70/ZT70 models.
post #1720 of 11493
But if the problem is with a static rather than electronic part of the TV the fix could be as simple as drilling or cutting some more vent holes. That's easier and less expensive than distributing and installing thousands of new fans. OK, who's willing to start drilling? smile.gif
post #1721 of 11493
I'd have no problem cutting complete holes where the fans are and replace with wire mesh......I know that would 100% void the warranty though. I was planning to do this after the normal 1 year warranty expires if I'm bored but quite honestly even wall mounted with the screen about 3 inches from drywall with the air diffusers, you can hardly hear it. Interesting enough though, right now I have an intermediate solution on cooling my preamp that is kind of loud (much louder db wise compared to the ZT60 right now) and I noticed during the quiet scenes, the ZT60 actually is more noticeable simply because of the whirling/pitch of the sound....not necessarily the noise level.

I've been doing the back and fourth with the X900 and ZT60 for about a month now; just got back from BB; after pulling the trigger on the 65ZT60 due to 20% reduction- 2x price difference sealed the deal. Panel is scheduled for July 27th delivery and install; with BB Silver Rewards calibration to soon follow...

Cheers!

Congrats! You'll love that set! Waiting for delivery is always hard wink.gif

Picking my 60zt up on Wednesday! Should be a noticeable improvement over my LG PK550 and 50G10.

The problem with this is everyone has the same back panel. That would mean the same fan noise exists on all models and the only difference would be the environment. I don't believe that's the case. I think there is an issue with some fans, or fan controllers. With the relatively infrequent occurrence of the issue, I just don't see design playing a part.

It's possible there are some variances in where the fan sits in relation to the vent holes that could account for different sound levels.

Yes, congrats! I also bought a ZT60 today at Best Buy (60"). Mine is scheduled for pickup on the 17th. They said delivery would be on the 24th, so I said I'ld pick it up to save a week. I'm just glad the months of research and debating is over. Should look a lot better than my 2003 Samsung 46" DLP.

True, but that would be a manufacturing variance, not a design issue.

I think all units have some degree of audibility. If so it's a design issue. That some appear to be worse than others would indicate it might also be a manufacturing problem. My money is on the design side of the equation being the primary culprit though.

Unfortunately my BB experience stats imply otherwise, and fan noise seems like a design issue that amplifies exponentially in some environments. My last exchange is scheduled for mid-August, so I will report back. This time, a GS installer will bring the new TV to avoid any possible accidental damage or droppings by warehouse employees.

Edit: BTW, GS install is only about $50 more than the basic delivery. It is something to consider if you care about the screws not being stripped by a rushed power driver/drill on the back of your new TV and also want a clean delivery.

BB basic delivery is free, isn't it?

Yes, they always zeroed it out for me. But, it was listed on the return receipt varying at $69-$79. They told me GS install is about $120 total including delivery. If I knew that from start, I would've pushed for GS install, or on a $5K total purchase, I would've paid the extra $50 just to be safe.

I noticed the same price reduction and bought a 65 for the LR and a 60 for the BR. I was planning on a 55 VT for the BR, but the price drop changed that dynamic! cool.gif

The VT50 has many more vent holes then the VT60.

I´ve got some questions for people that play lots of games on their sets smile.gif

Since the reviews on HDTVtest and Cnet suggest that the input lag is somewhere between 30 and 50 ms, how does playing on those sets actually "feel"?
And any problems with IR yet? And did you people had a break in phase, since there seem to be many different opinions if this is actually usefull or not.
This would be my first Plasma btw....the new Samsung highend sets seem to take away 90% of the picture options when you want acceptable input lag :-/

Though I haven't gamed on the display, I have seen some quick IR. When I've popped up the apps screen, and taken about 15-30 seconds to select an App, I get some short term IR. I notice it on solid colors. The reason I saw it is I went into Vudu app to see a preview. The green MPAA preview screen showed an entire row of IR from the apps screen (a row of app icons). Note that the icons had only been on the screen less than 30 seconds. I hit back a few times and rewatched the beggining of the trailer. It showed on the green screen (I never made it far past the green screen before I went back to see if I was imagining things). Letting the preview finish killed all the IR.

I was in THX cinema mode. Anyway, you may need to age the panel some to reduce the chance of IR. I don't have lots of hours yet and that may be why I picked up quick IR from static icons. Not trying to scare you off, but I have seen it when I use the built in apps (Netflix caused it to, saw bits of the interface when I accidentally exited netflix and went back in -- saw it on the red netflix splash screen). Again, it just may be that the panel needs to age a bit to calm down. I don't know if ageing will help or not. I definitely wouldn't game on mine right now after seeing it given I have less than 150 hours on mine.

Ordered mine yesterday!
post #1739 of 11493
I have had my ZT60/65 for less than a week now. It is wall mounted style (I use a Zen mount stand) and have had no fan problems. It seems they both run at the same RPM at all time, but the right fan does go to a much higher RPM for a second or so from time to time (I have only noticed it two or three times) and gets back to its normal quiet stage. The right side of my TV gets terribly hot to the touch.

Any single person using a single dealer is not statistically significant. If anything, it would point to a problem related to a bad batch of parts. It would need to be accompanied by a much larger sample size of similar issues experienced by people that have received their products at varied times and locations. This would also elevate return rates, at least slightly. I find it far more likely they have inconsistent quality levels in the fans or fan controllers that they use. I agree that you having 3 bad apples is significant, but you are making assumptions many levels deeper than your data supports. Also, free basic delivery should be included with any TV in MHT.
