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.

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.)

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?

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.

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.

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....

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.
