I'll give it a try a bit later, and pray that it works! Thank you for the help!

Calman Calibration Software, using the Dynamic Range Workflow for Brightness and Contrast, to get the Columns at their Lowest Points across the board: on my PN64F8500 - Brightness 46 Contrast 84. At these settings, Columns are all virtually either, very slightly above the Zero line, or at it. Cell is left at 20 re Doug Blackburn's talks with Samsung re ABL, and the best setting.

American "US01" Model?

I just purchased the the 64" F8500, but it won't be getting delivery for a few days. I was told the unit was the U.S. model(as in a US01 model), and not an import. Can anyone tell me how I could check that when the drivers deliver it my house? I'm sure it is printed on the label, but what exactly should I be looking for?

Thanks for the help!

My wife wants to rearrange the living room. She wants to put my 60 f8500 about 8" from the side of a fairly drafty 4' tall 8' wide window. I live in Minnesota. What do you folks think? Am I right that the possible cold could damage my set?

Considering the heat these tv's generate out of the back, I don't think the cooler air blowing on it will hurt it. The biggest threat to plasma are power surges, and heat.

The back of the tv will have a label with Version number. US01 should be the version number.

that's true if it's ALWAYS on. but the worst thing for electronics is constant heat/cold cycling. that's how condensation builds up, and that's never good.

ultimately it will be the jvc x35, but I've been 'practicing' with the f8500. you can see my results so far(I haven't got into the cms yet) in the f8500 settings thread


and I'm sure i'll give my other displays at least a solid once over as well.

I was figuring if he was from Minnesota, the window was better insulated. If he gets frost or moisture on the inside of the window in the winter, then condensation would be an issue for the tv close to it. If no condensation occurs on the window, then it should not be an issue. Being from a cold northern climate too, it's quite hard to keep the humidity in the house higher than 35 or 40% in the winter even with a humidifier attached to furnace.

If the screen is too bright with that high contrast, then reduce cell light, and of course, brightness.
the problem with the contrast is if you put it lower than 95(lower than 100 actually I believe) it shifts the 10pt controls and totally messes up the greyscale. it can be fixed, but it takes a lot longer since the 10pt controls no longer line up. I actually haven't heard(or personally noticed) any change in dithering from adjusting the contrast. i'll have to check that out too.


that being said, when I did mine, contrast at 95 and cell light 20, gave me about 50ftl, which is way bright imo. I was able to get good results using contrast setting of 90, but that's still over 35ftl. I would considering that a good setting for ambient light viewing, but it's what I'm going to use full time until I feel like doing something better.




now, with all that being said, this is recent, and I've had my tv being used as my pc monitor with the contrast up at 95 and cell light at 20 for about a year. the ir is basically imperceptible, and never lasts. I now have over 1600hrs on mine, and I accidentally left it on overnight displaying avs forums for about 7hrs straight. that definitely left some ir, but it cleared up within the hour.


so, if you're getting 'the worst ir' after watching one movie. you're either very picky about ir, have a 'dud', or you need to get more hours on the tv. I don't remember every having ir issues, even at the beginning, but I always tend to be a bit overprotective at first, so I'm not even sure how many hours I put on it before doing anything that could cause ir.

Just to follow up with the IR on the F8500, I have managed to get VERY stubborn IR to the point where I suspect it's uneven phosphor wear (burn in!). It's feint, but it's there.


Ran the set for a month and a half at contrast 70 and cell light at 10 and had no issues, so I thought I'd crank it up to a more normal contrast 95 and cell light 13. However a month later, and now the Sky News logo is visible in the top left on bright scenes. Unfortunately the logo is bright white and since I was passed what I thought would be a sensible break in period I thought it would be ok. Seems not.


I have run the screen wipe for 3 hours a number of times and have watched full screen zoomed in channels on dynamic (torch!) mode to no avail. To be fair, it probably is dimmer and if I keep doing this for another month I suspect it will fade to point where I can't find it anymore. Even now you can only see it if you know it's there and look for it on a bright screen such as white or light sky.I noticed it on 11th August, so it's been there 3 weeks+ so far..

Just be aware that the F8500 is not immune to screen burn and IR...


Cheers

I recognize you said you allowed the TV to age for 6 weeks but did you actually check the amount of hours was on the set? It's not really about time but rather the amount of hours the phosphors have been active along with the type of content being viewed in order for the phosphors to age properly.

I've had my F8500 for just over a month now (with over 500 hours on on the panel) and up until recently I've keep my settings lower due to eyes being sensitive (and to protect the panel from IR while properly aging the phosphors) but I've been playing around with settings after reading some of the settings recommendations posts from Fierce_GT and I can tell you first hand the F8500 is very much resistant to IR, especially long-term IR.

I have a 2012 Panasonic GT50 and I followed the break-in procedures verbatim and I can't get through a Football game or CNN without IR from the tickers or sports logos. I still have the NFL Network logo on my Panny after several weeks. Used the Disney WOW Blu-ray and the IR remains stubborn. It will go away as other stubborn IR does on my Panny but it's nonetheless frustrating.

On my F8500 I never get any sports logos and the CNN tickers (after being on for over an hour) show up on the black screen the moment I change the channel and within seconds, literally, the IR from the CNN ticker is completely gone. Just to verify I'll turn on the screen wipe and not single hint of IR anywhere in the white slides.

The one major difference between the Panasonic Plasma forums and the Samsung Plasma forums is most of the repeated complaints on Panasonic are about constant IR issues. IR is barely talked about on Samsung.

Just from an observation of your post it sounds like either your phosphors didn't age evenly or you have a faulty panel. You shouldn't be having that much problem with IR.
