Hopefully, this will keep those doubters who claim this cloudiness problem doesn't exist quiet.

Yes it is, and I was actually unaware of this issue w/I went to purchase this panel. The photos actually do not do this panel justice - it is absolutely stunning on 720p/1080i and mind-blowing running 1080p material from my laptop via VGA - WOW

Again, my only gripes coming from an XBR960 CRT is that is cannot produce deep black/blacks like CRT and there is a slight motion blur [that your eyes adjust to] compared to CRT. But I knew this going forward and it's definitely not an issue for me. I have better color now and much better resolution/bigger picture - only suffering in overall color saturation; but not by much at all - but that's LCD.

I compared a lot of high-end panels, and I went w/LCD for I do not have light control for Plasma, and the XBR3 by far was best on overall picture quality. The Sharp and the Samsung are close, but the Bravia Pro engine is fantastic after ISF Calibration and I cannot live w/the banding issue of the Sharp. It's too bad; for I really liked the Sharp.

Nice setup man.

Glad that someone got a good one. I wish mine was one of the good ones but I ended up with a 50" Plasma so I got more screen.

Yours is the XBR3 mine was XBR2 wonder if the XBR2s are the ones with the problems?

I personally believe that XBR vs XBR3 shouldn't be cause for this issue as the panels and the 'engine' are the same between the models.

However, I tend to believe more on the manufacturing date on this issue unless many of those who have build in July/Aug claims to have cloud/backlight leak issue.
Looks to me that only few sets which those build date have reached the customers. Among them, I am not sure how many are in this forum and participating. Unless we have good statistical data, it is hard to come to conclusion. Sony may be the right entity to answer that

BTW, how many of us do have Sept/Oct build dates which are 'perfect'? .

Because it's the EXACT same panel, made in the same plant. The XBR2/S2000/xx96D series all use the exact same panels.

God I wish people who DON'T HAVE THE PROBLEM would shut up about it. If you can't see it during movies/shows that are dark, then great, YOU DON'T HAVE THE PROBLEM. But those of us who have the problem DO SEE IT.

Look dude, for starters, the image I posted IS with a signal going into it. It's a dark scene, but that's because it's easiest to capture with a camera that way. Trust me, when watching a movie, it's very easy to see if it's dark material. Anyone else will probably tell you the same thing.

As for the harping on whether it's a Sony or a Samsung, what part about "it's the exact same panel" don't you get? The issue is the PANEL, which is identical across all three product lines that I mentioned, hence people with the S2000/96D/XBR2-3 all seeing the same thing. It doesn't matter if I own a Samsung or a Sony... with the exception of the processing electronics in the set, they are the exact same panel.

Also, because of having THREE sets with the exact same issue, I no longer have a TV using this panel and have gone with the Sharp instead. I'd get you more pictures if I could, but no longer have a TV with this problem (because it doesn't use this panel) to do it with. Just sharing my experience to back up the others' claims that you seem to have such a problem with.

As I have mentioned before, I have a KDL-40V2500 with a significant cloudy backlight problem. I went to BestBuy today to exchange for a set without the problem. So after opening three other sets, and hooking them up, the problem was on all three sets as well (to varying degrees, but nowhere near satisfactory since I could easily see it in the brightly lit BB home theater area and they were all manufactured Oct 2006). Two of the three also had stuck pixels which really makes me wonder. I am definitely going to have to follow up on this with Sony as I can not expect Best Buy to open and repackage every set in stock until I find one.

Look you guys can flame on me all you want. I have looked at post #90 and #91 of all xbr threads their are no pictures? if im was in the wrong thread please post correct thread showing a xbr2/3 displaying a SIGNAL confirming uneven backlight.

This is my point!!! I dont care about any other models except xbr2/3.

Looking threw all the threads I have yet to see a uneven back light issue with this set "WHILE A SIGNAL IS GOING THREW IT".

I could care less about other models of TV's I just wanted to know if someone could post either a link or a picture of a xbr2/3 having uneven back light issues while displaying a SIGNAL.

no need to get upset guys just wanted to see what it looked like

my tv doesn't have this problem but when turning the tv on for the first time for the day i notice 2 beams of light on the bottom left corner of the screen about 3-4 inches in length but go away after 30 minutes after the tv has warmed up. a guess is when tv has warmed up things expand and compress and you can't see the 2 beams from the backlighting sneaking threw some small crack between something.

No need for flaming here.

Check out post 61 - it appears to be credits with a black background. Please tell me you can see the issue in that picture.

That black background might be a star field in BSG or Star Wars. The net effect is the same - annoying uneven blacks.

Hmmm...Posts 90 and 91 of this thread have pics attached to them. Do you not see the picture icons or is your browser not working quite right?

I did this out of curiosity because I wanted to see how the inside looks like. As I mentioned in the past thread, I hypothesize that this laying down may have "destressed" localized pressure points along the screen which may be causing the light patches or clouds. Just a guess.

To this day, my set still looks really good. Below is a link to a pic that I took of my screen under "extreme" conditions: the picture was taken in a completely dark room and the BACKLIGHT was at "10," which is the max setting. Other than the small patches at the upper corners, the backlight leakage/bleeding looks pretty darn uniform.

I hope you guys can get this issue resolved with Sony.


wait wait wait... so you just unscrewed the back of the TV panel & re-screwed it back on & that FIXED THE UNEVEN BACKLIGHTING?

why isn't everyone on this thread doing this right now?

I think that "kontai69" did 2 things, laid the panel face down, and unscrewed the back. From his posts, he thinks that the simple act of laying the panel face down "destressed localized pressure points along the screen which may be causing the light patches or clouds". Sounds simple and harmless.

Maybe the poll should be divided into 4 questions. It looks to me like the XBR3's don't have the "cloud" problem and the XBR2's do.

Keep in mind that my set is a 32" Sony LCD (KLV-32M1; July'05 build; made in Japan) and not the newer 40+" XBRs. I only paid $XXXX for mine.

Anyways, I think that laying my set face down on a table is what alleviated the cloudiness that I was seeing. In retrospect, the panel likely got "stressed" during shipment or when I picked it up by myself out of the box. I also made the mistake of laying the box sideways as I transported the TV box home. I imagine these larger 40+ inch LCDs would be even more prone to stressing, either due to shipping and/or manufacturing imperfections.

My clouding did come back when I later bumped into the TV by accident. As mentioned in a past post, I decided to rub the clouds with a microfiber cloth. This actually removed nearly all the cloudiness as can be seen in the pic in my post above. I thnk that the rubbing may have spread out the "localized stress areas" which I hypothesize may be causing the clouding. You all might give this a try; it can't hurt. Of course, use common sense when doing so: keep one hand behind the panel for support; don't press so hard that your fingers turn red, etc.

Again, to the "cloud doubters" who posted in the other threads: this cloudiness issue is VERY visible on regular TV/DVD programming whenever there were scenes with dark or black backgrounds!!! I feel like strangling the naysayers who say that the "complainers" have OCD and that the issue is only visible on a blank input.
Just wanted to rant.

True, but just don't tell Sony if you do so. At least on my set, there wasn't a tamper-proof sticker, so they won't know if you don't tell.

Just another data point. Made in Mexico, August 2006. No clouding. Even with a vivid setting in an unused input. There is a hint of too much red but with normal tweaked settings (Cnet) even that is gone.
