So if that "box" moves, the shadow is always aligned horizontally with the box. I haven't noticed it in any Blu-ray movies, but I have noticed it if there's say a ticker say when I'm playing a PS3 game or something.

thanks that picture is better, rather it doesn't look as bad as what I thought I was seeing. Is it like a dim strip that sits above the black bar and ends where the white ends?

Thats normal. Not sure what the proper term is for it. Banding perhaps. Mine has done that since day 1 with certain content and I have been unable to get rid of it. It wont hurt anything.

Yea it looks like banding to me too. Mine does it also.

Looks like some flavor of line bleed. Try a google search with line bleed and plasma and you will see its a common occurrence.

This has nothing to do with your problem, but what did you find in a 1.33:1 aspect ration that caused you to watch it exclusively for several days -- the complete 1960 Tokyo Olympics followed be a complete collection of Godzilla movies? wink.gif

Oh I opted for the 4:3 with the grey bars because in this country Directv only gives us 4:3 for all channels. Nice huh :)

I wanted to watch it without it looking stretched but I am not gonna unevenly age whole sections of my tv because of

my content provider's shortcomings.

That's what I was thinking too.

I think you would be fine with a 60" TV at your viewing distance.

I sit about 8' from my 60GT50 and it is fine. I probably could have gone with the 65" but that would have been pushing it a bit in size and in cost. I upgraded from a 50" 720p Panasonic plasma and the size and PQ improvements are quite nice smile.gif.

Yeah it's definitely not banding and is line bleed. This is pretty much exactly what I'm seeing though not quite to that extreme. It's only really noticeable when you have a somewhat solid background, so isn't really prevalent in movies and the like. I kind of wish I never noticed it because now I seem to see it everywhere. wink.gif

It can be annoying but I hardly notice it anymore.

I just did a update on my new GT50 and it changed the look of the volume bar. I think it was ver 1171 or something similar to that. Anyone know what else this update does?

Edit: I had previously searched this thread for posts about the 1.171 update and did not find anything initially. Searched again and found some posts about it. Looks like a browser update and the volume bar color change was added.

I would hold off if you can. 60'' ST60 will be cheaper and initial impressions sound very very good.

Very cool. I commented on the Eagle with contrails in your picture a while back. I was surprised you had no response.

I've searched everywhere, but can't find how to get into the service menu of my GT50 so I can check how many hours it has run.

I did find this below on HDTVtest.co.uk but it does not get me to the service menu.

Thanks in advance for the help.



Disclaimer: By entering and adjusting the service menu, you risk voiding your warranty and damaging your TV. The instructions below are specific to the British GT50 model, and should serve as a guidance only... I take no responsibility for your actions and outcome.

Input signal = whichever source you wish to calibrate, for example Sony PS3 into HDMI 1. Engage [THX Cinema] mode, display the test pattern(s) on screen, then while holding the volume button on the TV, and press 0 three times on your remote which will bring up the service menu.

Press 1 on your remote twice, which will bring you to the [WB-ADJ] submenu.

Once you're there, press 9 twice on your remote to change the picture mode to [Cinema]. This in conjunction with [Colour Temp] "Warm" allows you to calibrate greyscale in [THX Cinema] mode.

Press [3] to cycle through the RGB cuts and drives. I suggest only adjusting [R-CUT], [B-CUT], [R-DRV] or [B-DRV].

Write down all the values before you change them.

Use the volume up and down buttons on your remote to change the values.

Once you're happy with the measured greyscale, press [OK] on your remote to commit and save.

The [Exit] button will get you out of the service menu. Remeasure outside service menu, as it may be slightly different due to different brightness etc. If necessary go back to the service menu and adjust again.

I was also interested in accessing the SM to check out the hours used on my 60GT50. But after reading how complex it was to access the SM and the possible issues I'm fine not knowing how many hours are on my plasma wink.gif.

Thanks for the reassurance I spent the last couple days with all content using all of the screen using either Just or Zoom and as you said

the sides of the screen have almost completely blended back in appearance with the middle and the effect where the sides were distracting

me is about 99% gone

+1 Why does it even matter anyway. If someone was going to buy a used one I can see how they might be curious but other than that what difference does it make?

post #8425 of 9713
Hi,

I'm using this as my Home Theater PC:
- Windows 7 Ultimate 64-bit
- AMD Phenom II X4 960T 3GHz
- ATI Radeon HD 5450. Catalyst Center 13.1
Connected to P60GT50 through HDMI.

This setup was working fine with an old Viera TH-50PX80U, although the native resolution on the old Plasma is not standard, so I had to create a custom profile on the Catalyst Center that is good enough to fit on the screen. I was hoping that the native resolution 1920x1080 of the P60GT50 would be a smooth transiton, but I'm running into many issues:
- First time the PC started on the new Plasma, it was underscan and was not displayed fully.
- I updated to the latest Catalyst and drive, and now it was displayed fully. Everything worked great for a while.
- I switched to TV input, switched back and everything went bad.
- The video card started producing pixelation and other artifacts on the screen.
- I rebooted, and now with 0 overscan/underscan, the desktop is now too big for the screen, and being cropped.
- I tried to remove / reinstall the driver but it did not work very well.

I'm hoping to get advices / setting tips from anyone using an HTPC successfully with P60GT50.

Thanks very much and best regards.

I think I'll run to the store, stock up on staples, and gas up the car. Forget about the zombie apocalypse. We need to worry about the troll apocalypse... cause it's happening now.

Everyone knows I don't have a British model since the instructions don't work.

Does anyone know how to access the service menu on a US model?

Thanks in advance for your help.

You gave no indication whatsoever that you did not have a british model. Therefore it was difficult to assertain whether you had a problem with the instructions given, or required other instructions relevant for your model.

What you are requesting could render your TV useless if used improperly. I'm of the opinion that if you are going to start fiddling in the service menu, then you should at least have basic reading and comprehensive skills. Your lack of attention to detail and poor detective (google) skills make me think that perhaps some caution should be taken... However, since you are obviously such a charming individual, I say go nuts. Just mash the remote with your fist.

Um you kinda gave the impression you had a British model since you indicated you used the instructions from a UK based web

site which were for a British model. If I told someone I was trying to use instructions off a Japanese website to service my

vehicle I would not be annoyed with them if they assumed it was a Japan based model. Also I would really not want to come

off so hostile on a forum where 99% of the people are quite helpful and willing to go out of their way to assist.

I have some questions about Burn-In / Image Retention on the GT50.

When I bought my set new, I broke it in for about 80 hours (the set has now seen ~1000 hours of use) and didn't experience any burn-in within the last 4 months.

Now, it's beginning to show significant burn-in for some reason.

For example, over the last few days I've been watching hockey. Total time has been about 6 hours. Now, the score bar is burned into the set.

The Bell logo and menu borders from my Bell PVR menu? Burned into the set.

The ironic thing is that I have been totally crazy about "maintenance" since the set was first turned on. Every second day I run the Scrolling Bars IR reduction built into the GT50.

Thankfully the IR can only be seen when there's large expanses of similar colors like the ice in a hockey game. However, I know it's there nonetheless.

So, the questions are:

- How do I get rid of the current burn-in?

- How do a prevent this from happening again?

- Since this didn't show up for quite a while and now it seems to be caused by even an hour or so of watching hockey or a few minutes on the Bell menu, could there be an issue with my GT50?

Any help would be greatly appreciated.

Oh, and for those wondering, my set hasn't moved from the THX mode (NOT THX Birght Room) since it was first set up.
