Could it have to do something with the coax cable? I am using a HDMI to the TV, but we have a coax, then splitter to my modem and the other to the cable box.
It didn't seem like there was a good response to Viral Tarpara's problem so I am wondering if anyone has any recommendations or suggestions.
This has come up in the S60 thread as well as here before. I don't know that there is any proof... but my take and that of some others (albeit, not everyone, we're divided on this) is that there is significant dithering when these panels are new. It is most visible and provable when running slides because there is no content variance then.
Please also note: If you're coming from a smaller panel to any make or model of 65: Depending on viewing distance, you may see significantly more graininess than before. Customer feedback on various makes and models of 65's shows this somewhat often.
I had a 55ST60 that failed and when my 65PS64 arrived, I noted that I could see significant graininess at distances under 8 feet. Of course, the THX film society lists that as about the minimum distance for a 65. Why? Well, 1920 x 1080 remains a constant. So a bigger panel is necessarily going to have significantly bigger pixels than a 50 or 44 or whatever. So if graininess is bothersome to you, maybe see if you can increase viewing distance. Even 2 or 3 feet can make a big difference on this IMO.
My eyes are 20/20 left and 20/25 right. As such, 9 feet viewing distance is my absolute minimum for my 65 panel. That works out ok, but some may have a theater where it would NOT. Under 7 feet, my 65 panel just plain looks too grainy, period. If your visual acuity is better, you would understandably have to have a greater viewing distance, IMO. Opinions will vary for good reason.
IMHO, my 65PS64 had dithering reduce quite a bit in the first 300 hours. However, please be advised: So far as I know, no TV in existence can remove dithering caused by bad content. And I'm finding there is a LOT of that...
Example: Watching certain movies, some low light scenes had dithering so bad they were unwatchable. Same movie, go on to another dark scene and it was excellent. That right there is content driven dithering. That is to say, it would have looked grainy on ANY TV.
Just the same, I believe both my 55ST60 and my 65PS64 both reduced for dithering on average (NOT content driven) in the first 300 hours. Similarly, I believe motion blurring reduced in the same time frame. Others disagree and that's fine. Just saying it is my subjective opinion. Appears opinions are about 50/50 on the dithering & blurring reduction during break in.
It could be relevant that many have a 50 instead of a 65. "New dithering" might not be so noticeable on a smaller screen or so I believe.
Some people say graininess is less noticeable on a 60 or 55 and that they believe that may be the butter zone for a 1920x1080 HDTV. So if it continues to be a bother, you might consider swapping down for size. If you don't want to go all the way down to a 50PS64 and if you're not a video gamer, I can attest that the ST60 model is also pretty amazing other than video gaming input lag. Maybe a 55 or 60ST60 would serve you better? Just a thought.

Just purchased a tc-p50s64 from costco, floor model for $ 500.00 including 5 years of warranty. unit is in great condition, so floor model did not bother me, not at that price. I followed fairchilds calibrations, both cinema and custom. I did get nice flesh tones and color, but seemed to dull for me. I have owned a vizio 42in plazma for 5 years, and it still rocks, but the bezel is large and i wanted a larger tv. I used a roku with my vizio, but liked the simple apps on the s60/64. I did try this unit on vivid and adjusted it and it looks pretty good. Maybe it's these old eyes, but i'm wondering can i follow those calibrations and do something for a little more pop,, or is that defeating the purpose of this plazma. again just had it for a day now and being a floor model it did get some break in, maybe not like the slides, but i did not notice any problems with the picture, burn in etc.... waching distance about 8 to 10 feet, fairly brigt room , but no direct light on tv. Thanks again for any feedback
Shared settings will vary wildly between different panels even in the same model line. This could be that. I find that Vivid mode is so over-driven and distorted that it is absolutely useless to me - but panels and opinions vary. If you like it, use it. .
Another thought: Since it's a floor model, did it do a lot of hours in "torch" mode? (vivid) If so, I wonder if that might dull the phosphors? I doubt it, but it comes to mind.
This is probably too obvious, but being it was a display model, have you carefully (with proper procedure & materials) cleaned the screen yet?
I hope you find some settings that serve you well.
Short of Vivid mode if you think it is too much, you might try Moshock's settings. Those have a lot of "pop" though there may be signs of distortion because the colors are being driven so hard. It's not as wild as Vivid, though.
