Received my replacement 55VT60A on the weekend. I have decided to run it or Normal mode when I am watching free to air TV and Foxtel and THX Cinema when I am using my PS3 for Movies and TV series.
After watching approx 6 hours of sports over the weekend I can confirm that there is no image retention or burn (phew). I also updated to the latest Viera Firmware last night

The fan noise is still present and just as loud as the previous unit I owned. The first unit was a October 2013 build and the replacement a July 2013. Both of them are identical from what I can see as there is no foam fix visible on either of them. The question I am asking my self now is do I proceed with the service technician fan foam fix or not? I am still using the cardboard vents I made which cut out approx 30% of the noise.

Vinnie, I'll be eagerly awaiting your comments on the experience, and most importantly the result and if it was worth the risk to the TV. Thanks in advance and good luck with the fix.

I called Panasonic to have the fan noise fixed on my VT60. They gave me the local companies contact info who would do the work. Today I called the repair company and they said they only repair at their facility and would have to take my TV!

anyone else have this happen? I'm not letting them take my TV for a repair that takes a few minutes. They seemed to not even know what the repair procedure is when I asked them about it.

If it's a 42" then they will want to take it. That's been common for years, not sure if things have changed. Of course your tv is larger. It would take longer to load it up then fix it with potential for scratches:eek: That should have in home repair as far as I know, maybe you should call panasonic and have them forward the service bulletin.

If the ZT's back panel is installed improperly it will crack the front glass. I think the bulletin was posted in this thread. That issue applies only to the ZT

STIG: here's just my 2-cents on your comment. DO NOT LET A TV REPAIR COMPANY TAKE YOUR ZT PLASMA OUT FROM YOUR HOUSE! That fan noise repair and kit install can be done in house, safely, and with you keeping a careful eye on their work. I've ordered some parts & materials to complete a DIY fix I've been working on & designing, and will be posting it on this thread as soon as it's completely finished.
I hope you find a company that will do the work inside your own house. That is the only way I would do it,...but that's just my opinion.

STIG: out of curiosity, do you know the Build Date in your Plasma? Forgive me, but I haven't read all your posts yet, but what exact Model of Panasonic Plasma do you own?

ZT FAN NOISE: as there are many people who have had issues with fan noise from ZT's as well as VT's, I, along with some others have made comments as to venting holes, and lack of them, causing both poor ventilation and possible noise due to fans pushing air out of the poorly designed back panel. Just in case your interested, Google "Pictures of Rear Panel of Panasonic VT, ST, S, models" from previous model years. If you look at those previous model years, you will notice a distinct difference in the location, but more importantly, the number of ventilation hole patterns on the rear panels and especially across the top of most rear panels. I mention this just as an observation I thought some of you may find both interesting and helpful? I will be having the fan kit installed in my ZT, and as promised, will post pictures of technicians work on those fans. After that, hopefully my fan noise will be reduced enough? If not, I will then post pictures of what I call, my Mini Acoustic Panel, that also reduces fan noise. Finally, no one likes having the rear panel removed from their Plasma. In the final scenario, I may use a special Dremmel tool and bit to drill out ventilation holes that match the patterns on previous generations of Panny Plasmas, 2012, 2011, etc. I just thought I'd post this observation and my opinion in case it's of any interest to some of you?

There are no fans in anything below the VT series. I am not even sure the VT50 had fans built in and if it was new to 2013 models on the VT and ZT. The ST60 and S60 do not have any fans and that would be for earlier years as well.

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.

Getting my 55VT fan fix applied right now. The service technician is also adding the neoprene washers I supplied to reduce the play in the fans mounting. FYI he has replaced both Fans and added two strips to the SC fan only. Ill have a good listen once the job is done. Hopefully some improvement.

Seems like a pretty simple job. Getting the back cover off seemed fairly easy and I could not see any risk of damage etc.

Ok so its been a few hours and the first thing I will point out is that the noise is still there and not completely gone. What has changed is that the noise is reduced and not as noticeable as before. Im guessing about 30-40% noise reduction. Overall I'm pretty happy with the result.

So I got my ZT60 back in June 2013. I have been debating on if i should get the Kit or not before the Warranty runs out. Now about reading these stories about Cracked Glass, and knowing this TV isn't made anymore, i am starting to think that i wont get the fix, and avoid having anyone touch my TV. Maybe i will wait till the warranty is up, and create more holes in the back panel, or make them bigger.

I am in the Bay Area in Mountain View, let me know if anyone in the general area has had the Fix done to their TV as well. Gotta decide if i want to get it done or not.

Hi all,

I am new here. As a lot of you, my Tx-P55vtw60 has noisy fans. I found a lot interesting info from all of you and try to apply them. But before removing my tv from my wall and opening the back panel, I would to know if it is possible to see the build date from the menu of the tv? Or should I detached it from the wall? Thanks.

Sets manufactured for the North American market have a sticker located on the back panel which has the build date printed on it.

In NA the first five digits on serial number will tell the year and day in numbers. Like #13254xxxx it would be the 254 day on year 2013.

The first four digits will give you the information. Like 3254xxxx would be the 254th day in year 2013.

I don't think the build date is available in any menu. I was in the same situation as you. I had already mounted my TV on the wall, so I was unable to see the build date under the mount. Fortunately, my mount pulls out from the wall and pivoted enough that I was able to loosen one side/corner of the mount enough to pull it back and read the tag using a flashlight.

As stated in the last few posts, the fan noise will still be there even with the factory fix in place. Mine has the factory installed fix and it still annoys me almost every night. I'm following this thread in hopes that someone comes up with a miracle cure! smile.gif

jlgoa,

Check the very right hand rear of the unit about half way down. You may find a tiny black sticker there that has the serial number. (Right hand side looking at the screen.) If there is a sticker, you can calculate the date from s/n info described in the posts above.

The serial number should be on the shipping box too. That said, swiss (european) sets use a different serial number scheme, so you may have to dig a bit further back (in this thread?) to find how theirs correspond to manufacture date. (Also, swiss sets may not have manufacture date on the backside sticker.)

Somebody not all that long ago (from Netherlands?) had the fix done, a month or two ago. May want to check the last few pages...

What was the volume measured at without the fix and after the fix. I have a projector that measures about 30db and sits right above my head. You can definitley hear it but it eventually just gets lost in the sound.

Just curious how loud these fans are compared to that.
