The ZT has 3 fans. I can't imagine adding additional exterior fans would do any harm, as long as airflow in & out isn't restricted.

Notice the thermal infared pic you took? The brightest areas were ironically over the areas of the screen the were suffering the uniformity problem

High temps causing the uniformity issue?

I'm thinking about maybe buying larger case fans and mounting them on the *outside* of the set, on the bottom part, to boost flow.

I also notice a blotch that starts showing up after several hours now on the *right* side of the screen. It is *directly* over the hot spot. Running the screen wipe or alternating several red green and blue full screen IRE patterns seems to lower it some.

Any other way you can think to get cooler temps without opening the set?

Anyone hear of repair shops or techs putting in stronger fans? Two fans for a plasma seems not enough... my previous 2008 Panasonic had 4.
80mm usb fans. Place them directly over the vent holes. They will push in cool air.

They can be plugged into the tvs usb ports so they will shut off when the tv is off.

Coolerguys has some 80mm usb fans.

ps: Ive already had my zt60 shut off due to overheating. It happened once and it was random.

But i was in day mode ( with the contrast near 90 and panel bright at high ) so I know it mustive been overheating.

hasn't happened since but I've been looking into usb fans ever since to help cool it down

You're probably better off sucking air out than pushing it in.

Correct

I stopped by best buy today to see what is new since I haven't been there in a while. Man its like a circus of tvs. Samsung has this new huge section with all sorts of sizes/curved/straight this and that. Although some of the 4ks did catch my eye, the motion was off to me, and the color was insane. Like almost made me blind insane. It gave me a headache! I'm so happy I got plasma, the picture is smoother, softer, natural like. Guess we will see what happens with 4k Oled

Mo!

Where is the third fan? (With 1 and 2 being in the upper left and right corners.)

Panasonic ZT60 and VT60 Fan/Fridge Noise Production Numbers
mo949's Avatar mo949 11:47 AM 08-19-2014
The ZT60 has a 3rd fan that the VT60 does not.
Its in the middle.
repete66211's Avatar repete66211 12:04 PM 08-19-2014
The service bulletin shows a VT60, which has only two fans. (The webcam is at the center top.) The ZT60 has 3 fans, which can be seen in member goosesdizzel's post here and here:


This would lead one to believe that the VT60 might be more prone to damage caused by heat, no?
Grendell's Avatar Grendell 12:06 PM 08-19-2014
Yeah, I see it now. In the middle.

Thanks for that pic.

I'm looking at this:

http://www.newegg.com/Product/Produc...82E16811999130

And then using double sided tape to attach three of them to the following locations (on the outside), sucking air out:



Maybe only using one fan instead of two on the left (although that board seems to run hotter).

I'd probably rather use a USB hub with a swith on it rather than use the set's ports for power.

Does any of this sound ill advised?

Here's the thermograph again:



The two boards with the black heatsinks seem to be running the hottest.

That thermograph is taken from a distance to get the whole panel in, when moved closer to the set, the hot spots increase to a ~110°F - 115°F reading.
mo949's Avatar mo949 12:26 PM 08-19-2014
Make sure your double sided tape is heat rated to about 130F.

Alternatively you can use what I did, which is real Duct (HVAC) tape and seal it around the sides to create the most static pressure.

So,the 65" VT60 only has 2 fans? I know that my 55" only has two.

Dont suck the air out if there are no vent to allow air in...you'll create a negative pressure environment and no cool air will be drawn in over the hot components

Use the screws that come with the fan. You can screw them into the grate like a pc case. Thats what I plan on doing I used double sided tape for my led strip and it kept coming off once the set heated up....
Grendell's Avatar Grendell 03:10 PM 08-19-2014
It seems since there are three fans blowing out at the top, then the three fans I would add in the bottom/middle should probably blow air in.

Mine did that once back in Jan/Feb, I thought the power had blipped or something. This was before calibration with the contrast up pretty high.

I just got a PS4 that I have hooked up to my ZT. I was wondering what picture mode other people play their games in also what precautions should I take to avoid image retention. Thanks.

I'm sure that there are people who use ZT60 displays for gaming, but I wouldn't.
repete66211's Avatar repete66211 05:51 AM 08-21-2014
I game with a PS3 & Xbox 360 fairly regularly. You'll want to disable any unecessary HUDs (especially if they're white) and use a picture mode with Contrast set no higher than 70. Pixel orbiter can alleviate IR in some instances so the THX modes, which don't allow this feature, may not be the best modes to use when gaming. Also, if you are going to pause the game regularly you'll want to use the screen wipe while doing so.

I really wish the Panasonic remote had a hard button for the screen wipe. As it is, I programmed a macro on my remote to engage it, which I use all the time when pausing games or 4:3 content.

I game on ZT60 with THX bright mode all the time, no problems.

I also play my Xbox 360 on the ZT. If I plan to be away from it for a while, I use the video mute feature on my AVR. I haven't had any retention issues.

Is it true that, in comparison to the VT60, the ZT60 display contains no MgO, or magnesium oxide, making it less susceptible to burn in or IR? I remember reading that somewhere, but just wondered if anyone could confirm.
repete66211's Avatar repete66211 01:54 PM 08-21-2014
The ZT and VT panels are the same. Where they differ is the ZT's improved anti-glare coating.

That's what I thought, but I did read that somewhere on this forum I believe. If that's the case, it's obviously not true.

Panels are both are the same NeoPlasma Black 3000 - Filters are different Ultimate Black for ZT & Infinite Black Ultra for VT

Big difference is the way the screen is attached to the panel, the Filter is on the INSIDE glass surface, held there by the autoclave process.

Studio Master Panel
The ZT60 series features Panasonic’s Studio Master Panel for increased performance and superb contrast. By removing the pocket of air between the panel and the front glass, the Panasonic TV’s Studio Master Panel improves light transmission and minimizes reflections from external light.

"If you look at the Panasonic TX-P60ZT65 from an angle, you'll notice that its pictures don't suffer with the 'double imaging' issue you see with every other Panasonic plasma TV when viewing them off-axis. This is because Panasonic has managed to remove the usual air gap between the plasma panel and the front glass. It's something that's only been possible by manufacturing the ZT65 screens in autoclaves - rare, high-precision heated compression chambers required to make sure the panel layers bond together correctly."

B T C's Avatar B T C 02:37 PM 08-21-2014
Thanks, Bob. I knew about the different filter and no air gap on the ZT60, but was curious about the MgO comment I read.

This may be a bit off topic, but would you guys, or ya'll, have any reservations about buying either a VT60 or ZT60 with no warranty coverage?
repete66211's Avatar repete66211 02:44 PM 08-21-2014
I didn't buy a warranty for mine. Naturally it comes with one year of coverage, which is when any inherent issues usually appear anyway. I'm not sure if I'd buy used unless the price was nice. For example, ~$1,500 for a 65" ZT with no visible IR would be a compelling offer.

Could this be it? Much to technical for me

Or is it related to magnesium sputtering as it relates to image retention? I remember talk about that from some time ago.
