Didn't have to. But supposedly they are the exact same fans. Just without the foam surround on top. I've been fighting a cold for the last few days and not sure if my hearing has really been affected, but I can no longer hear the tv noise. I'll post again in a few days once I'm all better. lol

For all those wanting to know the process and result (for my 65vt60), I got the fan/foam fix put in 5 minutes ago. I called Panasonic and described the problem (I had a July build I got last week and didn't want to return the beast). They made an appointment for me and a few days later a local tech came out.  He installed the foam and the whirling fan noise is gone from what I can tell. It still has some Plasma buzz on brighter images (and very faint fans), but nothing I can hear with the sound on. For me - the fix seems to have worked!  Here are some pics I was able to snap (including the instructions) during the process, which I thought was kind of cool.  Hope you all enjoy your TVs as much as I am mine.

I am now completely satisfied with the noise level as it is near zero.

Do the new fans have same part number as old fans?

Anyone knows what the part number for the foam fix kit is for the ZT60? Someone posted TXANV0113SER as the part number, but his TV was a VT60 I think. The tech who'll be doing my ZT60 told me the part number is TMKH292. Could the VT and ZT really need different foam sets, or is someone wrong here (the person who posted that first number or the tech)?

Has any one ordered direct from PANASONIC?
post #966 of 1365
I called Panasonic today, Monday, PM. The rep (Joedy) knew immediately what I was talking about. After the obligatory Q&A, she set up an appointment to have the fix installed in my April build 65VT60. My October build 60VT60 is very quiet by comparison.

No hassle at all.

So is it definitive that Panasonic is using new fans on the later builds and will replace existing fans that exhibit noise on earlier builds? Are the fans actually a different model or is it just the surrounding foam being removed? I had the fan fix installed but can still hear the noise. It's not horrible, but if there is indeed new fans available I'd be willing to try them.

Just an educated guess...
If Panasonic's foam fix doesn't work, their next step is to replace the fans with identical ones just to take that out of the equation. In case the fans were faulty and vibrating too much.

I think the foam is put there to dampen and prevent any resonant vibrations between the two fans. One might spin ever so slightly faster or slower and when the the vibrations meet between the two fans, the frequencies' wave forms line up to amplify the sound at certain time intervals giving it a slowly pulsating sound.

If you are bothered by a totally different problem, which is the sound of the airflow, I would put some acoustical foam directly behind each fan by the wall. I wouldn't do anything that impedes the airflow at all as some posts have described. I haven't seen the ratings of these capacitors on the circuit boards but as a general rule, the rated life of a capacitor doubles for every 10 degrees Celsius below it's rated temperature.

If a capacitor is rated for 5000 hours at 50C, it will last 10,000 hours running at 40C. I THINK most of the capacitors in this TV are high quality 105C 5000 hour Japanese capacitors but I wouldn't push my luck by putting a filter directly behind the fans, which impedes the airflow.

The instruction sheet that comes with TXANV0113SER says "Affected Models: VT60 & ZT60 series" (instruction sheet is same as the one pictured in post 962 above).

(And yes this was a direct order from Panasonic via that part number.)

I ordered some extra fans and some regular 80mm PC fan grilles. My plan this weekend is to take the back panel off and cut out the holes over the fan on the back panel and add 80mm PC fan grilles. If the problem truly is the air going through the holes the problem will be solved. If the problem is the fan or air being pulled through the bottom of the fan then my plan b is to install new fans that have the blades removed (so TV does not put up error message) and mount 120mm 5V fans on the outside with a 80-120 adapter. The 120mm fan is rated at 42cfm so I have to think that is moving move air that than tiny factory fan. I already have made up a USB to 4pin molex cable to power the fans. the 120mm 5V fans are rated at .23A so 2 of them should be able to be driven by a single usb port. I am just about done aging my panel so the USB drive will go and the fan usb power goes in its place. Then I have my Chromecast and Antec usb bias light using up all the remaining usb ports and hopefully I am done with the TV and can finally enjoy it for the long haul.

I did find some appropriate foam and applied the fix myself but found the fan noise still persisted. While adjusting the fans I noticed a fair amount of play in the rubber sheaths, or what have you, so I decided that perhaps some rubber washers would tighten things up. Thankfully that is what effectively eliminated significantly reduces the fan noise and in particular the oscillation and whine that was quite obnoxious, the fans are still audible but are much softer.

To those that need to address fan noise or have applied the foam fix but still have fan noise I highly recommend getting Neoprene washers, 5/32 in.
Remove the screws from the rubber sheaths then place a washer beneath the head of the screw. Reinsert the screw to the sheath and that should remove any wiggle room.

I was having trouble getting support to provide the foam fix for my July built VT60; the customer service rep wouldn’t acknowledge it no matter what I said, so I decided to take things into my own hands. You can order the foam fix at http://www.pstc.panasonic.com/EpartR/PartsListChoice.asp. It’s part number TXANV0113SER. It comes with the four foam pieces plus the service bulletin. I’ll probably also try the washer bit that KMFDMvsEnya mentions in post 596 while I’m at it.

Did you try the washers and if so did they work?

Also, anyone else in here tried the washers? I got them from Home Depot and am going to ask the tech who will be doing the fix on my TV to use them anyway, but I'm curious to hear about anyone else's experience with them... Thanks.

I did the fix and washers myself. Honestly if you look a few posts back, it helped, but I hear the fans during quiet scenes so I am trying to experiments this weekend to hopefully kill this noise once and for all. I also have some fans coming to try some experiments to as well. I suspect when all done I will have the grille holes removed and external 120mm fans as the best way to quiet this down.

Oh my all that noise does distract from the unbelievable picture quality!  OLED don't have fans

post #974 of 1365
So Panasonic is not using a new fan model in the "fix #2", but rather replacing the fans with the same model? And if nothing is wrong with the fans you have, that it's the flow of air through the vent holes that is the issue, then they won't help? I guess I could have a tech out again to see if replacing the fans does anything, but I'm doubtful if it just a swap with the same model fans.
post #975 of 1365
Well I was about to cut out the grille holes this weekend when the spider web fracture appears at two point at the top of my panel. So BB is picking it up Saturday and with no new ZT60 inventory left I may scoop up a VT60. So we will see what I get in a VT60 and then I will wait before trying to quiet any noisy fans.

Fan noise! is it as loud as projectors?

So sorry, I just bought the ZT60 60"

Congrats...is the air noise bothersome?

Just placed the order on Amazon, I sure hope it's not noisy?  Who has installed this TV on the wall? And what mount would you recommend?

post #983 of 1365
Wow, 65" or 60"? There's only a few of the former left. I am using it on the stand but the owner's thread has more info on recommended mounts should you care to look.

EDIT: Nevermind, the 65" are completely sold out.

60" link please

post #985 of 1365
Probably not the appropriate thread to post links to retailers. It's easy to find on Amazon (they have 118 left as of now).

So far so good smile.gif

Any wall mount from Monoprice will do, unless otherwise specified in the description.
I am using one with my 65ZT60.

Yes, I bought the 65ZT60 June build and there was an oscillating fan noise.
I had the repair and that cured the oscillation by stabilizing the fan.

However, the fan noise is still noticeable.
I don't want to take the TV apart again, nor do I want to cut the TV, or put modified plungers on the back.

I would like to find some soft 1" white foam to cut an put in back of the fans to stop the sound bounce back.

For those in a panic about the possible fan noise, fear not.  The majority of owners don't have the issue or can't hear it.  I have the 60"zt60 and have only noticed fan noise if I put my head behind the set, where the fans are.  Otherwise...no fan noise.  The ZT and VT are quality panels.  Panasonic is not going to offer a TV that sounds like a refrigerator, so fear not.
