Sony dropped full array backlighting from their lineup after 2012 I believe. They said the production costs were simply too high so I doubt you'll see a full array set in their 2014 line of TV's.
That's me in the video. I posted a thread about it here that got no replies, then found people talking about it over here! :) http://www.avsforum.com/t/1512422/ticking-from-speakers-sony-kdl-65w850a#post_24229404
It seems to me that you shouldn't get noise from the speakers even without an input if it's designed well - it should just turn them off in that case. But regardless, input, no input, it makes no difference. Even with the TV audio set to use an external system, which should definitely turn the speakers off. The sound does vary seemingly randomly though, so sometimes you can only hear it if you really mash your ear up against the speaker, and other times it's clearly audible on the other side of a quiet room.
I have contacted Sony and they said they were unaware of any problem, but would check with the techs and get back to me next week. Maybe if the rest of you having the same issue call as well it will increase the priority. It seems fairly likely that the TV's power supply is throwing off noise that the speakers are picking up, so the real fix would probably involve a design change in the power supply. Hopefully something as simple as swapping out some filter caps.
Does everyone get this sound to some extent if you put your ear right up against the speaker? Or is it only some of us? If the latter, I'm going to hang onto the TV and let Sony repair or replace it. If all models have this though, I may return it to Future Shop while I still can and look for something else. It's no problem when it's quiet, but the problem is I have no idea how often it's going to be at the more annoying level, and it would drive me crazy during quiet scenes in movies and that kind of thing. On the other hand, the picture quality is great and I would hate to take this one back only to end up with a poor panel. Argh why can't everything just work? ;)
Good thought, but no. Just tried it in a few different plugs, as well as with a surge protector. No noticeable difference.
Also, the sound is definitely coming from the speakers themselves, not a fan or something - both bottom speakers, as well as the one in the top-center at the back. Usually it's loudest through the left side one, then the top, then the right, but not always. (You can tell it's the speakers, because if you move your ear to a different part of the venting, away from immediately in front of the speaker, it gets quieter.)
If it were something you always had to put your ear up to the TV to notice, I certainly wouldn't care, but for some reason, it does regularly get louder than that. Not super loud, but enough to be annoying given the 'ticking'. If it was pure white noise even, it would probably be fine.
I'm not exactly sure. I was just looking at all the new stuff. I was in the internet browser and then did something to leave that and go to something else I can't remember and the screen flashed to something else for a split second and then back to the browser. That was all she wrote. The only key on the remote that worked was power. I know this is somewhat vague but that's all I remember.
I also managed to lock up the TV in this same way, also while trying to use the browser. Can't recall exactly what I did and haven't tried to recreate, but the browser does seem to be the common element.
Thanks for confirming the problem is not unique to my TV. Whew! When it happened to me I had not updated to the latest firmware, but I then did so. Since then I have had no recurrences BUT I have not played with the browser again.
Mine is wall mounted too, but I suspect that has more to do with the proximity of the speakers to your ears.
I did contact Sony already. They do in-home repair. Could be too much noise from the power supply, or inadequate shielding/filtering in the audio board as you say, or even in the speaker connections themselves. Hopefully Sony will come up with a solution. I'd really rather repair this set than replace since visually it's great.
A quick update on my vertical banding issues...
I replaced my TV this weekend with a new one.
I still see vertical bands during motion but they are much less pronounced. I was convinced on the previous set that the bands were affecting the still picture (which annoyed me the most, since I felt like I could live with the 'dirty screen' during motion if I had to) whereas on this set I think I see them only during motion.
From what I have read, it does seem like many large LEDs can have banding problems and it's mostly luck of the draw as to what you get.
I love the TV otherwise, so at this point I don't think I'll play the lottery and try to exchange for another set. Although tbh, I'm a bit disappointed to have any issues with something I paid over $2K for.
The Olympics starts a couple of days before my 30 day return window and I'll have to see how this thing does with all motion on white snow and ice.
You know, I swear if you guys had a beautiful woman naked in your bed you`d be busy checking her for skin imperfections.
