Just got my ZT60 65" installed today - no excessive fan noise that I can detect! Hooray! This is an absolutely beautiful television - loving it.

I opened a case with Panasonic for the fan noise on my ZT60 today. They are supposed to call with appointment information about a service call soon. I will post how it goes.

Just thought I'd chime in to report on the 55VT60 I purchased in late July with a production date of July 2013. I'm pretty picky about noises, imperfections and performance issues of any kind in my high-tech gear. But I'm happy to report that my unit doesn't seem to exhibit any excessive fan noise of any kind.

I need to put my ear right up to the rear grill to hear the gentle whirring going on. If my head is in front of the tv (close enough to squash my nose against it), I cannot hear any fan noise. At least nothing my admittedly Heavy Metal-calloused ear drums can pick up.

Not sure if this means they may have ironed out the problem in later runs, I'm just lucky, or I'm actually going deaf. I can accept any of the above if it means being 100% happy with the jaw-dropping quality I'm seeing out of this thing (even before calibration).

How is Magnolia (BB) with fixing the problem? Can't believe a TV this spendy has this issue. My previous GT50 was silent. Truly loving the picture, but not loving the fans when at low volumes. This sounds like my old DLP which was 8-9 years old!

Unless you are in your return window and want to exchange I would recommend calling Panasonic and scheduling the fan kit for installation. Seems to be what everyone else has done with "relative" ease. Read back a few pages for additional info.

Or just wait it out and maybe you'll get used to it. I'm nearing that stage now.

All,

I just got the foam kit put in my TV. I do not hear the fans anymore even when the sound in muted. Since my TV was under warranty I had the repair guy come out. After watching him do the repair...there are only about 40 screws you need to remove and the back panel comes off with ease. There was no warranty seal anywhere nor did he put one on after the repair was done. If you don't want a repair guy to come out and do this, just do it yourself.

Get this done people!

Here are some pics of my TC-P65ZT60...





The repair guy said Panasonic issued another technical repair order that says to flip the rubber things around (he did this on all 3x fans)

Glad to hear the fix worked out for you. Is it completely silent from your seat when TV sound is muted?

What about heat? Do you feel the case go warmer after the fix?

It is completely silent now. I do not hear the fans at all, even when the sound is muted.

The heat is the same and is a non-issue. I asked my repair guy if he has seen any heat issues and he said heat issues are only caused by not enough air flow around the TV.

Okay thanks. Hope this solution has the same effect on my 50" VT.

The whining is really annoying and it's not getting better after 100+ hours like some mentioned.

When I contacted Panasonic last week about my fan noise, they were going to call me back about a service appointment. I didn't hear anything back for several days so I called them again this morning with the case number. This time, they asked me lots of questions about when I hear the noise. I hear the noise when the TV is showing ordinary content and it is a lowish hum that pulses (gets louder and then softer). She asked me to unplug the HDMI cable and listen again. It is not as evident with the blank screen but I suspect that is because the TV isn't generating as much heat. They finally agreed to have a service call done next Thursday. I will have to have the TV unmounted from the wall before the service call. I will post the results of that service call next week. I will also call the service and ask if they have the fan noise repair gear.

My repair guy said the first TV he did with the fan foam kit was a VT and I was the first ZT he has done. He said that VT owner was very happy with the results. I believe he said the quantity of foam stripes were were different on the VT vs the ZT but I cannot remember what he said for sure.

Panasonic seems to have issued Fan Fix 2.0. Please refer to goosedizzel’s post #158 in this thread (http://www.avsforum.com/t/1478361/panasonic-zt60-and-vt60-fan-fridge-noise-production-numbers/150). In this version, the rubber bushings behind the fan unit attachment points have been reversed, effectively moving the fan housing away from the back cover and creating a new void space and presumably a new air flow pattern. Is this change responsible for the reports of now silent displays?
You can determine which version you received by comparing your set to the attached photo. The pic is of the left fan of my 65VT60, with Fix 1.0. The arrow shows the interface of the back panel and the foam on the perimeter of the fan housing. There is no gap. In a version 2.0 fix there will be a ~1/4”+ space between the foam and panel.
Has anyone else received version 2.0 or was this actually a case of a “senior moment”?

Yes and no, this was done today on my 65VT60, with great results I can add. Sitting on the couch I no longer hear any disturbing fan noises.

I have to say that the repair guy only had the fix kit with him, no instructions on what to do at all. Luckily I had read post #158 of this thread the day before so I could tell him what to do. smile.gif

Get this done people!

I was wondering if you can get the foam fix package to apply it yourself, or buy from Home Depot.

BTW, what if we just rotate the rubber bushings ourselves. Do you think that is going to change the fan noise without the foam strips?

I've purchased these foam stripes at my local hardware store before in the past.

Someone else would have to test that theory. I'm sure we all would be interested to know.

I am also wondering if just re positioning the rubber bushes is all that needs done to get the desired result. Many who have had just the foam inserts done over at Avforums report that it was a total waste of time.

I can attest -- not a waste of time. I believe it's all acoustics and psychoacoustics. The inserts may have not made the fans quiet but at least they took the hum out of the frequency where I could hear it.

On top of that, giving it more thought I think if we just reposition the fans to sit closer to the base without the insert foams actually changes the dynamics of air-flow, and the fans may not work efficiently.

Today a tech came out and installed the foam kit from panasonic on my ZT but we were both puzzled because the fans were still loud. Was very disappointed to say the least but after seeing post 158 tonight, I decided to change around the rubber on the fans myself putting the fans squarely against the foam kit and away from the back panel. Lo and behold! It works. The fans are very quiet and even after muting the TV they are very very faint. With the volume at 20 and up, no fan noise. Wasn't hard at all to do, whole procedure took me about 20 mins.

While reversing the bushings may indeed cure the problem, we have no idea whether or not this might adversely affect the cooling of the panel. I’m aware of only a single occurrence where the service tech reversed the bushings without prompting from the customer. I have to remain a bit skeptical that this is a Panasonic authorized remedy. I know they haven’t called me back to say they didn’t do it right the first time.

The temperature remains the same as before, keep in mind it's not resting on the panel but on the foam kit, and looking at the way the foam kit is instructed to be installed there will be ample space for the air to circulate.

As great as the picture quality is, the fan noise is annoying as hell and takes every bit of enjoyment out of whatever program you're watching. Besides we all have have a 1year warranty, ample time to test this solution, if it fails hey 20 mins you switch it back and call panasonic. After all who can tell the way you had it before.

I realize it won't be the same, but does anyone have an audio recording of this up close that we can compare to ours up close?

Fan noise, that is.

The repairman just stopped by and he installed the fan fix (I think version 1.0 from what it looked like). It took him about 20 minutes (most of that removing and installing the back cover screws). It seems better from the brief test after the install but I will be able to tell more once I have it remounted on the wall and I give it a good workout. I will post about that later.
