There's a product called LightDims for this that is well worth its low price.

So I recently came accross second hand TC-P55ST60. Is it advisable to buy 2-3 year old plasma?


This tv retailed for around $1,500, what would be a decent price for a used set?
Anything specific I should look for when I go to check it out, other than dead pixels?
is there a way to check how many hours its been watched through settings?

I'd check for uniformity. I've had three ST60 50's in my possession and all had some amount of pink discoloration on gray backgrounds. If you don't have a test pattern go to the Eco menu. The mostly grey background will show it. It's worse on gray but I would also see it in shots of the sky etc in normal content.

As long as the screen and filter and bezel etc are in acceptable condition, and the panel doesn't show any burn-in or issues it should otherwise be fine.

It actually retailed for $1,295. That was the regular price Panasonic's online store, on Amazon, and at Best Buy from late summer to end of production in December. I kept waiting for a sale to occur but after a few months i ended up buying mine for full price ($1,295) before they disappeared.

I'd check the panel for hairline cracks (shine a flashlight over every single inch), and of course check to see if it has any burn-in (using the colored break-in slides on a USB stick).

Quick way to Check the Hours Used Via the regular User Menu (same for all 2013 models):Go to Menu > Help > Version > and scroll down to Status4. On that line you'll see a letter A or B or C followed by a 4-digit number which is the number of hours. A0039-0000 for instance would be 39 hours. C1926-00000 would be 1,926 hours.
As long as the TV is in good condition, i wouldn't obsess about high hours. The panel is rated for 100,000 hours before brightness is reduced which is like 30 years of watching it all day long.

Posterization, all plasmas have it. I doubt you can find a flat screen TV that doesn't have it somewhere in the grayscale.

This sounds like greyscale tracking error to me and not posterization.


Edit: Or it could be non-uniformity.

Yes, as Randy said check for burn-in/image retention, and also get the hours that have been put on the set. Depending on the hours, you might be able to negotiate a lower price. But there is no need to fear high hours if the set is in good shape and has no burn in.


I'd say a fair price for one with less than 3000 hours in excellent condition with no image retention is around $1000, but I don't think I'd pay more than $1000 unless it was pristine with super low hours.

I also own 2x 50 inch ST60 model. I do notice that too... the pink discoloration is mostly on the center of the screen and is only noticeable in full white and gray backgrounds (in Cinema mode, of course). When I watch a bluray Hollywood movie the pink discoloration is barely noticeable. Another thing I noticed is that when I watched Schindler's List (a black & white movie) a week ago I noticed a hint of green & pink tint here and there, depending on the graduations of the gray . Is there a way to cure these discoloration by getting it professional calibrated?

Yes, or you can get a calibration disk with greyscale patterns and try to improve it by eye, but it's super tough to do that.


This set can be super fine tuned, so it's one definitely worth getting professionally calibrated. I recommend Chad B, but there are many good ones who post and participate here.

The higher the contrast is the less you'll see it. Higher quality sources show less of it than lower quality sources.

Thanks Randy for this bit of information. I've had my TC-P60ST60 since May 2013 and never knew that there was an hours counter in the "Help" section of the Menu. I've got 6437 hours on mine and I believe it looks just as good as when ChadB calibrated it. I'm sure I could use a touch up calibration though.

You can't calibrate out uniformity issues. Chad B would tell you the same.

This is why I eventually sold all of them. Pink 'blob' in some portion of the screen...greenish tint elsewhere. And my meter would detect it as well (Which is why you can't calibrate it out...the meter will get different readings on each portion of the display and the adjustments are universal for all areas of the screen).

Don't get me wrong....I don't mean this as a knock against Panasonic since personally I feel like no manufacturer cares all that much about uniformity anymore. I assume it costs money to achieve it and they can't be bothered.

My F8500 has some discolored areas on a white test pattern but it is nowhere near as bad as any of the ST60s were and of course the F8500 has other weaknesses that the St60 does not. I just though that ultimately it was a better TV for ME because uniformity is very important to me.

It didn't sound like he was describing a uniformity issue. I believe he was describing an issue with grayscale tracking, where there were color tints depending on the gradiation of gray, which I do fix with calibration.

Edit: my mistake, sounds like he has a uniformity issue (which I can't fix) and possibly a tracking issue as well.

Some of the 50" models of the Panasonic 60 series are known to be problematic, something that has received surprisingly little attention in the US - perhaps the 50" size is less popular there?

You might take note of this thread:

http://www.avmagazine.it/forum/74-di...eeding-e-aloni

Note: that is the VT60, which in Europe was available in the 50" size (unlike in the US). However, in terms of the issue noted in this thread, it is a TV that behaves similarly.

Some of the behaviour of these TVs is quite unusual, so it tends to be misunderstood or miscategorized. This is an image that was in that thread:



You might look at that and think that the upper part of the screen is prone to pink tinting. But that is not the case. What is happening there concerns the number of subpixels illuminated at one time in a single horizontal row. When that number is large, the whole row or the centre of it tends toward a pink/magenta tint. If you look at that image, you will see that the non-dark part of it is wider at the top than it is below. It is the width, the geometry, of the light part that is associated with the tint in many cases, rather than the screen position per se, but that is to probably to oversimplify. If you want an extreme example of this phenomenon, see below:




One can only speculate as to the cause, but you should note that grey is particularly awkward because its reproduction requires all three subpixels in a pixel to be to a large extent active. If you have a wide horizontal grey line (and a plain grey screen consists of a set of these), then you have a large number of subpixels that need firing, relative to say a red screen for which the green and blue subpixels are far less active. So maybe it's some sort of load issue? Hard to know.

What I can say is that I've had 3 entirely different "high-end" Panasonic plasmas and none has had perfect uniformity. On my current VT, I tend not to be bothered too much by this, which in most instances is very slight (the coloured line bleed is the most noticeable aspect, but it is not everpresent to a detectable extent). I can imagine, though, that some people would be aghast, especially given that these sets were awarded "reference status" by some reviewers.
