Official Sony KDL-EX640 Owners Thread - Page 5

I have a 46EX645 and I'm wondering, does "white balance" do anything?

If I select "custom" so that advanced setting and white balance adjustments are enabled (for example, using the CNET settings listed in post #17), I don't find that the RGB gain and/or RGB bias adjustments do anything.

I find the blues tend too much toward the purple side of the scale (from the CNET settings), but even if I max the gain and the bias (I tried all 3 of the R, G, and B with no difference) it doesn't visibly change the blue at all.

The gain is negative so I guess it's actually attenuation (zero is the default and changes are in the negative direction), so I would think that a more negative gain setting on Red and Green would make the Blue go more towards a pure blue but it doesn't seem to do anything. Is there some other setting I need to change before the white balance adjustments have an effect?

About all I seem to be able to control for blues is darkness or brightness, but nothing via the white balance control.

How do the 42EX440, 46EX640 and 46EX645 compare? I know the EX440 so suppose to be really good with input lag but I would like a 46" or larger TV.

No, I've yet to contact SONY about this...being that I got it as a very reasonably-priced replacement for an aged (out of warrently) 52W4100, that had developed 1 small horz. line issue.

Will cont. to "sit on-the-bench" for this one as the Misses wouldn't relish me going-on about it.

Yeah, I understand. I went to Costco and looked at 25+ tvs very closely. None of them had that hot spot or any other anomalies at the edge of the screen. I have another call in to Sony about it. I will post back when I hear something.

Called Sony and told them the replacement had the green issue and they said they will ship another tv. At some point they are losing their shorts on shipping and white glove delivery. It's got to be $150 each time at least.

I will report back on tv #3 when it arrives.

Fingers crossed.

Well now they are sending out a refurbished tv with a 2 year warranty. I bought it with AX so I will have 3 years total. At first I dd not want a refurb but with the new tv's showing the same issue I am hoping this one works out.


Update: After I emailed them that it is within 30 days of purchase, it should be new, they are stopping the shipment and sending a new unit.

I have yet to search this thread manually, but does anyone have any input on the useless web browser? I think it's Opera browser and I get a lot of out of memory, page too big to display errors.

Thanks!

It's pretty cumbersome, but I have not had any memory errors. I would expect though with large sites it may happen.

I tried and found it very awkward to use. If I want to browse the web on the TV or to Skype I use my Ipad connected to one of the HDMI ports and mirror the iPad display to the TV.

So...question for you...are you saying that a 40ex640 TV DOES NOT HAVE AUDIO RETURN CHANNEL! I bought one a few weeks ago and asked before purchase both at the store and on the sony live chat if it did have audio return channel and everybody said yes

I was afraid of that. It would seem that .mobile sites work fairly well, but their tough to search for and you still have issues with flash video not loading. I was considering a mac mini, but I guess an ipad would be less expensive way to do it. Can you get wireless mouse and key for an ipad?

No ARC. Just used optical out to receiver.

Good morning,

I just bought and received a KDL50EX645.

Amazing picture quality... But like many others, in a pitch dark room, I do see minor flashligthing at all 4 corners, but major flashlighing or clouding in the middle of the screen, many half a foot by a footl.

However, you don't see it at all when there is pictures, only on a full black screen..

Would you guys try to buy another one ? I think I may go purchase a second one and perhaps keep the best out of the two..

If the second set is identical I might have to change set.. We'll see..

Any comments ?

So having been through this (i just set up a 60" 645) I'd recommend:
- make sure you set the tv backlight correctly. Down from max to 90 can really make a difference. Check others calibration settings, fiddle around etc. This makes a huge difference
- consider an led backlight (for the back wall)for critical viewing. I set one up and was amazed by the improvement.

With above i have it set up so i barely notice the flashlight effect with any light in the room, but it's there a bit. But when i really want to be picky, i just flip the external backlight on and i can watch in a completely dark room. Its the best picture I've ever seen and I've been doing this a while.

Read the manual! It's talked about in there. Normal for these Edge Lighted tv's to do that.

I'm not sure which to get the Kdl40ex640 or the kdl46hx750. The 3d would be nice but not required. Cnet's review video says the kdl40ex640 has a better picture than the kdl46hx750. Can anyone confirm this? Also which would be better for some analog cable channels?

Both will look about the same. 3D is dead.

Hey Guys,

Ok, so as I mentionned in my previous post, I'm the proud new owner of a Sony KDL55EX645 but after watching my TV in a dark room for the first time, I was really unimpressed with the amount of flashlighting I was getting from the screen... Lots of people are saying it's normal, but I mean it was all four corners + 1 foot by 1 foot in the middle of the screen.

I decided to go buy a second set just to compare... New set is perfect... black everywhere...

The only problem I saw is 1 dead pixel on the bottom right. It bothers me when i'm 2 ft from the TV but from where I sit, I cannot see it at all.

I think that since I have a perfect set (no flashlighting) I should stick with the dead pixel instead of trying to get another set with flashlighting..

As for the PQ, it's awsome! My old TV did not have 24fps.. It's crazy lol

I have had 2 and the flash lighting is minimal on both. The edge lits due suffer from dirty screen syndrome-when the scene pans left or right with light bacgrounds, the colors seem uneven. It's the short coming of an edgelit vs backlit.

I would take back and get another and try.

Hey avs people and ex640 owners. Long time lurker of avs and decided to share my calibration setting (had it 'professionally' done hope it works well for others too, im really happy with it.)
Picture 95
Brightness 58
Color 50
Hue 0
Sharpness 1
Color temp warm 2
Noise/mpeg reduction off
Motionflow and cinemotion as you will
Everything in adv settings off/0
White balance:
R gain -2
G gain -2
B gain -13
R bias -11
G bias -9
B bias -7

I will say I didnt know what to think of it when it first got done but now that ive been using it a while I cant go back, cable/htpc/xbox, I use it for all and am very happy with this tv, hope my settings work for others as well

Anyone get the software update last night? Any idea what the changes are?

I got it - v1.245. Dont know what it does but my channel banner still has incorrect time. TV picture looks great to me. Same as before the update.

I was going to say the tv looks better now, but I thought it was just me!

Another update. The green area-top edge, in between center and right side of tv-of my screen is gone. Not sure how and it doesn't make sense-break in?-but it's gone. Just wanted to put this out there in case anyone else has it, seems like it will disappear after 50 or so hours of use.

Anyone else having issues with Hulu+ after the last TV update? On shows longer than an hour, about 3/4 the way into the program, I get kicked back to the main Queue page. Like the show had ended, but there is more show left. I just can't access it.

These settings are awesome. Thanks!

I am not a gamer and the only sports I watch are soccer and rugby. Mainly I watch HBO, movies, Daily Show, Colbert, PBS and a few specialty channels. For my tastes Girmic's settings are the best I have found for my EX645. Thanks for posting them.

I do have a question. The settings do not include a backlight setting. I can experiment with this myself but I am curious, does the EX640 not have this setting?

Hi! From yesterday I have a problem with Netflix on Sony KDL-EX640. There are a info when I tried watch a movie:

Sorry, video isn't supported on this platform.

I had chat with Sony technicals and Netflix technicals and no solve yet. The gug from Netflix said, that gonna clear my signal. And NOTHING. When Netflix guy tried do something, I saw a code: ui-303 under a info.

When I turn on Sony Playstation I had info to upgrade Netflix to version 2.11. I did it and on Sony Playstation Netflix working fine. But I prefer watch Netflix on Sony Bravia. What I must to do? How can I upgrade Netflix on Sony KDL-EX640? I must wait for Sony Bravia Update? Thanks for your help!

I had this same issue two nights ago (Monday night). By Tuesday evening, the issue had cleared. Perhaps Sony had yet to upgrade or had issues with the Netflix app?

Would you guys recommend this TV for someone that is going to mainly use the TV for PS3 gaming and HD satellite with the occasional blu-ray? I'm upgrading from a 26" LG LED that has bad backlight blooming problems and I really don't want to have to deal with the same thing.
