I did notice I have "fan noise" but it is so negligeable I can't see having a tech come over to do this fix which doesn't completely eliminate the noise anyway
IMO it's no worse than the fan noise from my Verizon DVR or the cental air kicking on and running, etc etc. Truth be told, unless the scene I am watching is dead quiet
I cannot hear any fan noise from my listening position which is about 10 feet away. This is even with lowest volume settings
Im pretty sure that if I didn't read about this issue here I probablly would have never given it a second thought.
Anyway the TV is phenomenal and is now on the verge of extinction. I feel I am lucky to have snagged one of the last untis available and I will enjoy the hell out of it until it burns out.
Try and do the same. Obsessing about an issue that seems to be quite trivial will never allow you to sit back and relax and enjoy it (im sure Ill take hell myself for that comment)
BTW, my build date is July 2013.
PS- D-Nice came and caliobrated it and it looks amazing with all content I've fed it.

Finally, at the 11th hour (month, more specifically) I had er' done! I will be intently watching for any signs of crackage over the next 3 weeks. I helped the tech, and I think we got her back in the groove successfully. As others have stated, there is maybe a 50% reduction in sound. Not sure it was worth all the trouble, and it doesn't leave me too exuberant about purchasing future Panasonic products when they take such a blatant engineering shortcut. Better than overheating but not very conducive to a home theater and the volume dynamics of movies.
soytainly, but the stress and fear of damaging the panel offsets the somewhat minor improvement, along with the fact that I had to help lift it off and back onto the TV stand (my tendinitis and trigger finger have made me considerably weaker, so it was no easy task) and cut my finger on the razor sharp metal of the back cover itself as we removed it. Finally, one of the screws near the bottom wouldn't even line up properly so as to be screwed back in, so it will be interesting to see what happens to the glass in the coming weeks.
Vinnie, do you think the result you got was worth the hassle? Would you have had the fix done if you knew before the fix what you know now?
Have we lost you to OLED forever?
I have the VT and has tried to solve the noise problem. I got a technesian out who changed the fans to new ones?!? That off course did not change anything and he had never heard of any foam kit :-(
I call Panasonic while he was here and they confirmed they had a foam kit but the tv needed to come to a servicecenter for this...
We tried the tv with out the back plate but the noise level was exactly the same as when it was mounted...
Dont know what to do now, either accept or try again with panasonic to get them to install the foam kit...
Also, consider installing a baffle on over the fans. Search the forum for different types you can build. Top Gun is one type. People have even tried the Plunger type. They work too!
I think you answered your own question. If the TV is full of dust you are setting it up for overheating and fan motor failure. Unless you have access to a air compressor with a high pressure nozzle I'm afraid your in for dis-assembly and cleaning.
I consider myself fairly noise tolerant. However, the Panasonic Vt65 fan noise drove my to have the foam fix installed.
The irritating whiny pitch was gone immediately and fan noise volume is way down. The foam fix is enough for me to the point I no longer notice the fan in low volume situations. .
The Panasonic service man told me that, in order for the foam to be effective, the pieces of foam must touch the fans physically. The key for the foam fix to dampen the fan vibration. I believe that the fan vibration is getting amplified by the enclosure. Others in this forum have pointed out the fan is silent when the back cover is removed. So, it lends credence to theory that the fan vibration is the main culprit.
Get the Panasonic foam fix installed first before passing further judgement. With the official foam fix, I am getting to enjoy more and more the spectacular VT picture quality.
I will push on for the foam kit and cross my fingers...
Panirama; when you say that the should phiysically touch the fan, do you mean the fanblades?
That said, I did apply your approach to what I replaced the pani with and automagically my new set had zero issues as soon as I stopped reading about esoteric and purist issues here.
This is a great forum but it can cause obsessive folks like me to worry about things that otherwise would go unoiticed. Still love the forum but just dont go into threads about my set uless I need something specific.
So that is good advice.
If the fan noise is ruining your viewing experience, sell the TV and get something else.
I recently purchased the VT60. I aslo have the fan problem and had the fix last week. While the noise is slightly less it is still unacceptable. I'm planning to replace the fans by bigger (slower) 120mm PC fans. The fan connectors are different from the connector on a PC fan. I don't want to cut the fan cable just in case I need to replace them for warranty. Does anyone know the name of the type of connectors used in the Pana? I will be placing my results here.
My projector is around 30db and it sits 5 feet above my head and does not bother me at all. I can't imagine the ZT60 fans being any louder then this plus it would be further then 5 feet from your head.
As you can see from the schematic below, the fan has a TachOut signal that goes back to the main control board and will detect that the fan is not at the RPM expected, the downside of this is that it is a variable speed fan and when the control circuit sees it is not running at the right speed it will raise the fan output voltage to the max or until it hits the speed it wants, so you may just end up with a big fan going the same speed.
Personally I would get a cheap fan controller from Amazon and manage temp and fan speed without tapping into the Panni circuit at all and just un plug the factory fan and accept the 11 flashes of the on off light, which is way better than the fan noise.
Disclaimer -- I returned my ZT60 due to the fan noise and went with another set, I knew it would drive me up a wall and that "noise" problems are very hard to fix, but I had it for a week and had bought the service manual, thus the picture. I still follow this thread to see if any actually fully beats this issue.
