Hello. I have a European 51E6500. As far as I can understand from the first post this "inferior" sized TV should have the needed pots to do this tweaking.
I had the 50" Panasonic ST50 for a little while and the blacks were the best I've ever seen. On the Samsung they are not so good when I have the lights turned off, but they could be a lot worse I guess.
What I really wanted to know is if adjusting the voltage pots could eliminate some green blobs and DSE I'm experiencing on this screen? It's very subtle and for the most part completely invisible, but when I'm playing video games and notice that the screen is darker in one area it really annoys me.
I read that Panasonic released a firmware somewhere that raised the panel voltage and that helped people with green blobs and DSE. Would raising the panel voltage a little reduce the green blobs and DSE on my screen? I figure I could raise the voltage a bit and compensate by adjusting the Yrr to achieve darker blacks at the same time.
The E6500 suffers from the so called "Brightness pops" I have for the most part learned to live with this, but will these adjustments have any influence on this, negative or positive? I have not experienced any "Floating blacks" at all on this set, but could that become an issue after adjusting the pots?
Post from another forum where I describe the DSE and blobs on my screen (the illustration is exaggerated of course):
The two red circles indicate a semi-dead subpixel. In 1 the green subpixel will turn off and on like crazy when there's a green screen. Oddly enough it's worse when it has to handle a gray screen like the one I drew, but still only the green color. Number two is red subpixel, and the problem only occurs when displaying a red color.
Neither of these show up during normal viewing, and I think they have been like this from the very start. Only noticed them when I inspected the green and red screens in the DVDO Edge's test pattern sections.
The white spots are areas where the screen is a little brighter than it should. The top one is the most noticeable one. I found this immediately after getting the TV, but simply because I was looking for something like that. During normal viewing I haven't seen it.
The green one is a green blob, I guess. This is just above the Samsung logo. This can be seen if you look for it, but you really have to look for it.
The dark areas is where the screen is darker than it should be. The darkest area I found when playing around with the Miiverse feature on the Wii U. It's noticeable when scolling a white screen with black text up and down the screen. Not otherwise, but it should be noticeable if using a webbrowser too. **The brighter areas are only seen when you are very close to the screen and therefore not a problem. I think, and I really hope that this is a problem with the screen coating, because looking at it from an angle makes it pretty much invisible. I sure hope this doesn't get any worse, or across the whole screen, that would piss me off.**
Adjusting cell light and contrast settings doesn't seem to help.
Any thoughts on this would be greatly appreciated.
EDIT: 672 hours on this set so far, if that matters.
** I no longer suspect the screen coating. I believe this is DSE :/
