I attached an image of what is supposed to be a solid grey screen. There are dark spots all over the place and the dreaded creases on both sides.

anyway, had a house party the other day. loads of kids came and turned out the distance alert works flawlessly. previously i said it doesn't seem to work very well with my face even when i am kneeling, but it works 100% of the time with kids. they watched disney's tangled all together and every time one of them got close, the screen went dark and the message came up and everyone else started shouting at the poor kid :P

That's actually normal. That theme adjusts with the time of day. One side of it will be a stronger color than the other. It's perfectly normal and I can say this with confidence as I play my PS3 on a HD CRT.

The flashlighting is pretty bad on the bottom center and bottom right of the screen.

Apparently some level of clouding and flashlighting is normal on most LEDs/LCDs. See Geoffrey Morrison's article on this topic:

http://news.cnet.com/8301-17938_105-.../?tag=mncol;9n

"Nearly every LCD TV on the market has a problem: uniformity. Certain areas of the screen are going to be brighter than other areas. On dark scenes, this can be visible and sometimes distracting. "

"This LC/backlight system is never perfect, either due to manufacturing irregularities, design inefficiencies, or whathaveyou. Because it's not perfect, parts of the screen are going to "leak" light."

"There are multiple issues that make a perfectly uniform LCD difficult. The thinner the TV (and therefore the less distance between the backlight and the LC), make a uniform brightness more difficult, given there's less space to diffuse the light evenly."


For me personally, while viewing actual content from any source ( not grey screens) I don't notice any of the flashlighting symptoms described above on my HX820. In fact I am very impressed with the display capabilities of this TV.

I agree with you vaxick--I was trying to make that point in my post--but I guess I didn't do a very good job--thanks for pointing that out. :-)

I have to agree 100% with LBJ2.

I have failed to be unimpressed with this TV when actually watching content on it. Some slight uniformity issue on a grey screen doesn't bother me at all.

Well I've gotten most of the problems taken care of by dropping the back light to 1. My initial impressions of the set were disappointing, now I'm actually pretty impressed.

I have been searching for a new HDTV for a while now. I have changed my candidates several times. I have come to just LED and my favorite brand Sony. My first candidate was the Sony 46HX729. Then it was the 46NX720. Then I said, let's get the best, the 46HX929. But then I asked, is it worth spending $2100 (from Amazon) for mostly PS3 gaming, some for sports and some for Blu-ray movies and coming from a 2007 26" Vizio?

If not, then I was considering the Sony 46HX820 depending on the performance of gaming input lag.

The main issue I'm having a hard time getting around is that on bright scenes, the corners of the TV have a very blue'sh tint to them. Does anyone else experience this?

Another thing I noticed was "crushed" or clipped blacks. One scene had a dark wooden door that appeared to have no detail. I bumped the brightness up to 75 momentarily and sure enough there was plenty of detail not being shown.

What are the odds of getting Sony to send out another set?

I've measured lag on my set, with the gaming mode set to speed and it's 20-30ms.

I believe there are two types of 3D glasses you can buy to view 3D on a Sony 3D TV:

Sony TDG-BR100/B - 3D glasses ( the original pair that requires a battery)
Sony TDG-BR250 - 3D glasses ( the latest pair and is rechargeable)

They are both much more reasonably priced these days compared to what the originals cost a year ago. Check out this 3D starter pack at:

Here's an even better deal for the same thing:

I have the 55HX820 and I ONLY use it with a PS3 and Xbox 360. No cable, I just stream Netflix, Hulu, Vudu and watch Bluray's outside of my gaming.

Love the TV, but there is a fair amount of lag if you don't use game mode. I don't find the lag to be overly distracting so I just keep everything on. But to each his own...

The picture is far too blue. I prefer warmer and more real to life. I'm sticking with Warm1 for now, Warm2 is too warm.

Hi all.

I've browsed this thread but I couldn't determine a common judgment on viewing angles.

televisioninfo's Review is appalling in this respect

"The viewing angle of the Sony Bravia KDL-55HX820 was strikingly poor, falling below 50% of its maximum contrast when only 8˚ off-center. With a total viewing angle of 17˚, you will need to position yourself right in front of the TV for the best results. Although the contrast falls dramatically, the color remains relatively true."


but what really puzzles me is that their own First Impression Review (written by another author) drew a completely different picture!

"We were able to walk out to about 50° or 60° before we noticed a significant drop in the contrast ratio. The picture held up pretty well after that point, though: even though it wasn’t great, even at almost 180° we could still see a picture with passable contrast."


Well, after having seen a KDL-46HX820 in a shop, side by side with other TV sets, I agree with any single word of First Impression above quoted: I've found a very good angle until 60° and an very acceptable quality even beyond that. Visibly much better than the nearby EX series TVs, too.
BTW, all TV sets I saw were displaying, at the same time, the same HD source, a movie with many dark scenes and with a lot of contrast.

So, I tend to believe First Impression and (even more!) my eyes much more than televisioninfo full Review, even if supported by instrumental measurement.

However, I'd like to hear more owners' opinions about this.

^^for me the picture starts losing contrast at 50 degree from the center. at 70 degree the difference with center becomes noticeably huge for me. and at 90 degrees it looks very washed out.

I suppose that beyond 50° or 60° a good degree of subjectiveness occurs about what is considered "acceptable", however your experience seems much more similar to televisioninfo's First Impression and to mine experience in that shop than to televisioninfo's Review (which found a "sweet spot" to just 8° off-center!).

Vaxick: If you bought the TV directly from Amazon ( not an Amazon third party) and want to exchange the TV I recommend you work directly with Amazon first and see what they can do for you. Looks like they have a free 30 day return policy with free shipping on TVs...http://www.amazon.com/gp/help/custom...&nodeId=901908

How bad is the crease?

Steve--I am really sorry to hear about all the trouble you are having with your HX820. For me this is one great TV.

I also got my HX820 directly from Sony as a replacement for my previous 2011 EX720 model ( which had an unwatchable 3D crosstalk issue). When I contacted sonylistens@am.sony.com about my EX720 trouble they were great--very responsive. They sent someone out to my home to examine the ex720 ( free of charge) and ultimately offered the HX820 as a replacement. I couldn't be happier with Sony service that handled my case and the result. Luckily my HX820 is very nice--no crease, no color crushing, no light bleeding issues or any of the other maladies you are experiencing with your set.

IMHO...If you haven't already done so it may be an idea for you to contact sonylistens@am.sony.com too--at a minimum maybe they will send someone out to examine your TV. Who knows maybe there is something they can repair or adjust.

Yeah we must have lucked out, mine has no creases, no evident cross talk, no flash lighting, and no clouding if evident at all is not as noticeable as it was on my old 52xbr6 it replaced as well through their exchange program.

Overall very impressed, especially when I was shipped 4 pair of br250 3d glasses as a courtesy from sony for free cause they wouldnt replace the tv with an xbr model and i pitched a fit.

You can try exchanging it but as I mentioned on my previous post every set I saw in two different bestbuy store had crease issues. The only ones that had a less visible crease issue were the 46 inch hx820s. Maybe it's the smaller size screen of the 46 that helps. There is absolutely no difference whether you buy from Sony or third party such as Amazon. I believe people here that believes they have a prefect 55hx820 are probably not looking close enough or not using a solid white or grey screen to examine for defects, which I think is smart because my picture quality is prefect until I started looking closer at the crease and clouding issues. Of course I could be wrong and there could be prefect screens out there but until I see photos of this perfect screen or until someone that has clouding or crease exchanges for a prefect one, Im sticking with the fact that this is normal on such a thin panel.

Ace1281 et al. After reading this post --I took the challenge to spend some time closely examining a gray screen on my HX820 and I do in fact see a very faint what you call "crease'" which looks more to me like the LCD panel itself around the entire frame of the HX820 just behind the glass. It looks very mechanical/man made or part of the LCD panel design--as opposed to damage from shipping or handling. However, due to slight imperfections in the frame --I can imagine that this panel may sit a a little closer to the glass in some areas of the TV frame then others on some people's TVs--so to some the panel's edge may be more visible in certain sections of their frame hence the appearance of a potential defect. Likewise I am sure back-lighting settings may increase visibility of the panel's edge. On my TV, the panel is ever so slightly visible equally across the entire frame all four sides of the frame only when I am in the highly entertaining "gray" screen mode. While viewing actual content--I don't see this "crease" at all and frankly I had to really study the LCD on the gray screen to even see this very faint "crease."

The good news, for me is I don't plan on spending too much time viewing white or gray screens on this TV .

For reference, take a look at a couple of pictures I found on the HX929 avsforum--this clearly shows the "crease" (the plastic strip) displayed through the glass and then the second picture shows the inside LCD panel ( the plastic strip) with what I think is the edge of the panel that has been nick-named the "crease".
http://www.avsforum.com/avs-vb/showp...postcount=3021

In summary, I now have to agree with some comments in this forum--I don't think this is a defect. For me this TV is still pretty fantastic at displaying 2D/3D content.
