The person who you quoted is talking about proper calibration with instrumentation (color/spectro meter). It is fundamentally different to what you have done which is 'adjustment', not "calibration".
People don't pay professional calibrators hundreds of dollars to come to their homes and fiddle around with an iphone app.

I called Panasonic, and they said they haven't heard of this before and have escalated the issue. But before I got off the phone, they said they would do not warranty any burn in issues. I ran scrolling bars for 2 hours and it is now gone. Not sure what would cause this or if anyone else has experienced this before.


I can't see anything burned into your screen, and if there is any burn-in you wouldn't see it when the TV is turned off like that.

If by chance you're talking about the two bright lights in the screen, that's not burn-in - it appears to be bright light behind the TV that's shining through the rear vents and lighting up the plasma panel from behind.

Looking through Red color filter it is correct in a completely dark room.

I don't have any big problem with that. I have HDMaster's extended evening settings plugged in and like the PQ; turning the color up to 60 doesn't really have as dramatic an effect as you may think. Actually, it's pretty subtle. I grabbed the THX set-up app for my iPad when it was free but don't have AirPlay or the HDMI lightning cable so I have never tried it to see what it says.

The shortcoming of simple tweaking (whether its based on an app or a disk) is that you can alter the grey scale and never really know it. It probably doesn't matter too much unless skin tones get out of whack or the overall picture takes on a color cast. For a lot of people reference levels can be kinda dull.

Maybe I'm wrong (I usually am) but I thought the problem was the two giant "white" circles in the center. If that's not it maybe the reflection of the Barcalounger has burned in smile.gif

Yes it was quite subtle. At the base setting of 50 I can clearly see the red box through the filter. Turning up to 60 it is lost against the red background. My room is pitch black and very comfortable to watch.

Afternoon all. Just got my first GT50. Unless I'm being a dufus I think it's DOA. I've set it up on the stand, plugged it and....nothing. I mean like with the power lead connected, nothing. Am I missing something. Is there a manual switch on the TV to get it in standby mode (I've round the bezel and can't see anything hidden and nothing in the manual)

There's no red light on the TV at the bottom (Im presuming that's where it would be)....so I'm guessing its a dead TV and the wait will have to go on

According to the instructions you should have been able to turn it on via the remote OR the button at the side.

Yeah you'd have thought, but I think it was set to off so probably not in standby mode...will have more of a play after the school run

Hey guys I have a 60" GT50. I'm using THX Bright mode, with the eco mode saving turned on. I like it, but does anyone have any other suggestions for bright room setting? I don't like custom mode, for some reason it looks weird compared to THX modes.

Why do you use the "Saving" setting as opposed to "Standard" doesn't that dim the picture ?
mohanman's Avatar mohanman 09:11 AM 05-02-2013
Yeah it does a little, because I like THX bright mode, but you can't adjust the gamma. I think by switching to eco mode it drops down the gamma just a tad.

This morning, I took possession of a 60" GT50 from a retailer that was previously a display model. Got it for a reasonable price, not great. The salesperson told me the TV have been on display for about 2 months. Even if it were on 24 hrs a day for 60 days, max hours should have been about 1450. Accessing the service menu, I see it has 4180 hrs and 435 power cycles. That's more than a year's use in our house! My first reaction is to call them and return the TV for not any other reason but that I was obviously not given the truth. Other than that, is returning the TV the most logical choice?

Thats about 6 months non stop. Probably about 3 years for me. With 435 power cycles I would guess that they used it for roughly 8 months.
I certainly understand how you feel and that would be my first reaction. But....
How good was the price?
Does it work perfectly?
What kind of warranty did you get?
Do you think you can do better with your money?

Those white marks are on the screen when the TV is off and they are just as visible at night.

The white marks are also clearly visible when the TV is on.

I ran scrolling bars for a hour and it cleared up. However, when I got home from work the next day, they started to come back.

The initial Panasonic rep I talked to said that image retention can be seen even if the TV is off, for whatever that is worth. I am going to call them back tonight.

$1500
Seems to work fine. Got normal 1 year factory warranty.
Same money would get a new ST60. This is my first plasma coming off a 52" XBR4. More reflection than I thought there would be, but probably acceptable if I wasn't annoyed.

Bring it back and do not look back! Buy the ST60 NIB. I cannot see how anyone can justify keeping a GT50 with 4,000 hours on it for the same price as a new ST60 which will give you a better picture and is being compared to the VT50. There is so much more yelling I can do here but hopefully I won't need to do any more then this and you will already be on your way to bringing it back.

I would second that especially with 4000 hours on it.

+1 btw the S64 has an antiglare filter that may worth looking into for you. From what I understand its only available at Costco and Sams.

^S64 does not have 3D if that matters to anyone.

I would return the 60GT50 in a heartbeat for the 60ST60. I would first take a picture of the 4180 hrs. and 435 power cycles on the screen. Then I would go back to the store and ask to have what the salesperson said to be put in writing (if not already). Then I would show the screen shot showing that the information given was not factual. I paid $1599 for a NIB 60GT50 so the price you paid was not a very good one IMO. Good luck smile.gif.

i agree with others here - you did not get a good price and I would return it and get the ST60 - maybe at another retailer...

Thanks everyone for the "clear" guidance on my just delivered GT50 with lots of hours. Even though the hours really annoyed me, I also have quite a reflection issue. The TV is located in our family/great room area where it's difficult not to see window reflection. The salesman lead me to believe it wouldn't be an issue.... but, it is. If I knew the ST60 was less reflective, I'd give it a shot, else I'm back to shopping LED.

How can that possibly be ir? Did you leave it on while you were in Germany? What is behind your tv?

The panels are going to be similar I believe. Did you change the settings to make it brighter. Certain settings are darker by default. You are going to see a reflection in an LED as well. It all matters how well the panel handles the reflection. The ST60 handles reflections better then LED's I have tried.

Either way, get rid of that GT50!

If that is not an external light source then a faulty component is leaking current to the plasma cells

in that general area while the unit is off. That is very bizzare.

My other concern is that if the cells are being powered they are gonna end up aging much more

rapidly than the rest of the screen and that area will look very dark compared to the rest of the picture.

Taking into account my ultra-limited electronics know-how I call faulty board.

Also if the white spot is still there if you unplug the TV from the wall then it's quite simple, your tv is possessed

and you need to call a priest asap.

Hello All,

I'm a GT50 owner finally! Is there a safe way to enter the service menu and enable the 3 setting "Motion Smoother" option while in THX Cinema Mode? Right now it is greyed out.

I say this because other members in my family like the look of the "Soap Opera Effect". I do not. But I guess this is great reason this HDTV is such a great set. You are allowed to make your own choice SOE on or off - even with a Plasma!

Please walk me through the steps. I understand the risks.

Thank you,
J

I agree.

It also looks just like the images posted by people who have their tv's back to a window. It looks like light coming through from the other side.
