Official KDL..EX500/501 Thread - Page 157

The banding that you are explaining is not the kind of "banding" that my set suffers from. I guess there are two different types of banding that LCD tvs can have. my sets banding looks EXACTLY like this:

When I switch my tv to an input that doesnt have an input connected, (causing the screen to turn that darkish green color) I can clearly see the banding. This means that it is NOT caused by a poor signal or the tvs calibration, for neither of these have any affect on the "no input" screen.

I have called sony tech support multiple times about this. They said that it could be caused by a insufficient/inconsistent supply of power to the tv. They said that this is only a problem in old houses or in rural areas. Seeing as my house was built in 2005 in SF bay area, I dont think that could be whats causing this problem for me.

That is not banding. That is uneven screen uniformity that is bad enough to be seen in a video image.

This is banding. This is caused by the electorincs or screen of the a set unable to render the gradient shades of certain colors. This happens from inferior decoders and less than 8 bit color screens.

Again the ex500 line doesnt not have banding. What some are reporting may be some other type of defect but it is not banding.

Again, what would you say is the issue I am having? My post is a few back, but to sum it up there are faint "bands" that are visible in certain colors. Mostly lighter colors, grays and shades of blue or brown. Could see the "bands" during the movie tangled, especially the opening scenes quite clearly.

When viewing from no source, the dark screen images is free of the "banding" issue I am seeing and it doesn't show up in black scenes or white scenes. Any thought as to what this might be? Also another poster said something about hanging a TV incorrect....how would one do this? Anyway, other than this, I love the TV and my replacement from BB should be in early next week.

Thanks.

not sure, it is hard to say from posts on the net.

I am aware of what gradient banding is. The problem that we are expressing is uneven screen uniformity that also goes by the name "banding" (either vertical or horizontal "bands" that run across the screen). Just type in "LCD banding" to google and you will find hundreds of links such as this:

This defect can be compared to flashlighting which I think we can all agree is common amongst the ex lineup. Flashlighting can be caused by poor handling during production/transportation, well so can banding. Perhaps banding is extremely rare with these sets but it does exist. Many people may have banding on their sets and just never notice it, (after all you do need to actually try and find it in order to see it). If people just sit back and enjoy what they are watching they will honestly probably never notice the banding on their sets. Hell my GF or anybody else who watches my tv never claims to see it unless I point it out to them. If I dont think about banding I never notice it myself, otherwise I would have returned it months ago.

Thanks for the info....unfortunately with my set, the "banding" is very noticeable. If it wasn't that bad, i wouldn't worry about it.

Mike...nice to see you, I haven't been on that much either and when I get on, there ya are...hope everything is going well with you and yours!
I am soooo glad my 55EX500 is one of the great ones...I enjoy the set as well as now looking on getting a set for the family room..the old RP is starting to show wear and I really need to get a LCD for there.

Remember all, Sony does warn on using too long of screws if wall mounting! FYI

Hi Stu great to see ya too.

I guess I dont like the terminology used. To me banding is banding screen uniformity is screen uniformity. Im not sure if its sensativity to it or if the screens have gotten worse at the end of the runs.

One of the big pluses of this set is screen uniformity. Though that pic of black screen looks nothing like mine. When properly calibrated for 35 ish ftl.

Though if I were to crank up the backlight a notch or 22 I would most definitly see uneveness.

In order to get screen uniformity on an LCD you MUST use a proper calibration of lower backlight 0-1 maybe big maybe 2. And the ftl in the realm of 35ish.

This imo is most likely the cause of the newer users complaints. The guys that love the set and that have been here a long time use lower backlight meter calibrated type settings. the new kids on the black seem to be using settings that are not adhering to standards and are brighter.

This will give you uniformity problems hence the inferior image issues.

Just my best guess at it. And for infos sake this would pretty mcuh happen on any brand model lcd with higher backlight settings.

Your post cracks me up....if you would have bothered reading my post you would see I am using a backlight setting of 1 and using CNET calibrations. I don't pretend to be an expert, however I understand the difference of banding and screen uniformity. All TV's have defects, this one is no different. It is a great TV and has great uniformity, my issue is something entirely different. Also there aren't determined standards for televisions that say you have to have this setting and this....blah blah, otherwise they would come out calibrated at 6500k already so people don't have to pay for ISF calibrations. It is the standard for color accuracy and the way films are supposed to look, but it isn't a required standard for television sets. The only thing is preference and the way it looks in the eye of the user.

Like I said before though, Great Set, Great TV, I hope my next one is fine. I really like the set.

I usually watch my TV in a completely dark room so I keep my backlight at 0 at all times. Sometimes I will even turn the power saving on the high setting to make the backlight go even dimmer. With these settings the "banding" still persists and is as noticeable as it would be with the backlight at 5 or 10. And I wouldn't consider myself a "new kid on the block" for I have been following this thread since I purchased the TV 11 months ago.

Also screen uniformity issues are all usually connected to the panel itself. Banding however is a whole different monster, and has nothing to do with the panel. If I had my panel replaced it may eradicate clouding, flashlighting, mura, and any other screen uniformity issues, but the banding would still be there. This is because it is caused by the TVs internals/circuitry and its inability to consistently control all the arrays of pixels across the entirety of the screen. In the end it looks like a screen uniformity issue but does not in any way act like one. Adjusting the Tvs settings may help extinguish the visibility of bad screen uniformity, but not banding.

My statement was a generalization. You are perhaps sensative to something else going on. you do not need to get the set isf calibrated. I spent 100ish dollars for an eye1lt and learned to calibrate myself. I used it on my sets along with friends. Well worth all the money and time I have spent with it.

Nothing being sensative....just seemed you were singling out myself and another. No harm done and all is well. I may look into calibrating myself shortly.

Ahhhh, nothing like pancakes, bacon and the Three Stooges on a Sunday Morning...nyuck nyuck

Fixed

Just an FYI,

I ended up returning the set and getting a KDL-55EX620. I went through 3 different sets of the 55ex500 and all of them had the same issues with horizontal banding. I couldn't live with it so settled on a different model. This model is free of those issues.

I would like to say however that I think the 55ex500 is a great set, only if you can get one that is free of the mentioned defect I was having. Maybe I just had some bad luck. 2 of them were from Best Buy and 1 from Target, so they were different batches.

The 55ex500 was the first Sony set I had and it impressed me so much that even with the defects I was having on the sets, I stuck with Sony and tried another model.

Have a great day all!

serialmike say they don't suffer from banding so you can't possible have banding!

I found an excellent guide for setting your Xbox 360 HDMI settings.

Obviously havent read more than a line or two of my posts. But hey if you feel like thats enough to comment with proper knowledge of the discussion go right ahead. Just dont get mad when people laugh at you.

Wow...4 days since the last post...this thread is finally showing signs of dying off.

So true.

Not much to say now that its not current and most are sold out. No more noobies.

Settings are pretty much locked up with a few different good ones out there. The set itself is solid. I might go as far as to say one of the most solid CCFL sets ever made.

Long live my ex5!

I will be getting a refurbished one (60EX500) to replace my 60WE610 with a melted light housing. I am hoping it is as solid a set as you say. I did get 8 yrs out of this last Sony, hope to get as many with the EX500. Will see about applying the setting you have posted.

My first post to this thread, just read the first 71 pages - is there a post with pro calibration settings for the 46EX500? If so, was it done with a Minolta or Klein?

Dont think anyone on any version has used anything better than the eyeonelt and posted.

Let me rephrase, what post of calibrated settings would you use if you had the 46"?

Mikes settings work wonderfully even on my 40ex5.

I've only watched baseball on the EX500, how does it look for hockey and white ice accuracy?

If you're referring to mikes settings i only use them for movies. For sports I just use the normal sports setting and tone down the backlight a bit. Looks awesome for all sports though I'm admittedly not that much of a hockey fan

My question is more to do with watching a large white surface which in order to look accurate could result in player uniform colors looking pale. I've seen this on some other displays over the years. What's interesting is 10 years ago i had a Sony 42" plasma, the one with speakers at the bottom - for hockey anyway the picture was stunning and i've not seen a better looking hockey game on any other display since then including my professionally calibrated Elite Pro110.
