This is my second LG television and I must say I'm a bit disappointed.
I had a 2012 model 60LS5700 and now the 2013 55LA6900.

The 3D is nice, however the ARC in both models failed miserably, on two different receivers too.
On the LA6900 the ARC worked for 5 min right out of the box and now it won't budge at all. Same with the 2012 model that I used to have.
I switched to Optical out and it only drives two channels (stereo).

Does anyone else have this issue with the ARC, is there a setting I am missing?

EDIT:ARC is no longer an issue, it was a problem between the couch and the remote. See 4th post.

How is the performance of the set generally aside the arc issues you are having?? Can you post pictures? Have you tried gaming on it? How is the gaming lag?

Aside ARC issue and the optical only sending a stereo channel the performance is good.
I don't think I'm the only one having these ARC issues with this or other LG TV's.
Wondering if other LG TV owners are having ARC issues?
I need fodder when I call LG and demand my money back, I don't like owning cheap crap.

To answer your question, I have thus far played Batman Arkham City in 3D and Ghost Recon on the 360 on the TV and it is good there is no noticeable lag.
The construction is kind of cheap though, after wall mounting it i noticed I was able to push the screen in on the corners it has a little too much give and seems flimsy.

EDIT: After further research it seems that the part that I'm able to push in, is the 3D filter in front of the LCD screen.

Oh man is my face red, I had to setup the ARC output to Auto.
Once I did that the optical audio output started to pass through dolby digital and DTS.
Once I did that I had to go into the input menu and enable Simplink once I did that ARC started to work.

How is the audio quality of this set being 2.1? I was thinking about getting the 47" for my bedroom and didn't want to invest in a soundbar or clutter up the room with external audio equipment (WAF).

Alright here is a link to the pictures: http://imgur.com/a/4usWR
Sorry for the grainy pictures apparently G+ is now auto enhancing pictures.
I'll repost later after I put the speakers through the works.

It is a nice set that's for sure.
I've attached more pictures for you.
Also the 2.1 sound is decent, definitively better than all other TV's I've heard.
I listened to some Music and it was enjoyable.
I watched a bit of the Dark Night as well and while decent it wasn't the best, I mean there is only so much bass you can fit in that TV cabinet.
My TV is also wall mounted so that might make a difference.
All in all the sound is really good for a TV set.

I just returned my 55la6900 yesterday as is would turn off and on and never stop. They confirmed this at the store and I exchanged it for a different tv. BTW, this only happened with HDMI components. It had a great picture before it would shut itself off and the sound was good for a thin tv but I used my own audio. I suppose I just got unlucky, but be on the watch with this set.

Things like that happen, especially with the electronics of today, it's an inevitable byproduct of complex machinery and programming.
I for one am happy with mine, except for the local dimming it is really bothering me.

why does Local Dimming function bother you? is it something that you can do away with?

I'm considering this and the LA6200 model. Really still torn until now. gaaah

Very interested in this set, but not sure i can fit the 55", as the TV will be set in a corner shelf. The corner shelf is 57 inch (144.8cm) in its widest part, but with the TV stand, that will set the screen back some and then not sure it would fit...

For those who own the 55", could someone please tell what is the distance from the front edge of the stand to the screen? That will tell me how far back the screen is and whether I will have enough space.

Also, just read a review on Amazon saying that the volume is RF-controlled, not IR, meaning you can't use a Harmony remote that is IR only to control volume??? Anyone using something else that the included LG remote???

Thanks in advance!

The 6900 looks really sexy on my wall I give it that.
Local dimming bothers me in certain instances only, you can sometimes notice it dim. Also, I was watching a movie where it had one line of white text on a black background and I could see back light bleeding,
It can be turned off.

Major difference between this and the 6200 is the bezel, the 6900 has almost none.
6900 has a gloss finish which apparently reading some text adds to the picture quality, however in a really bright room it will reflect your room.
It's not noticeable once you are watching something on screen.
The TV disperses the light from lamps and bulbs in the room so you don't get a bright spot on screen, this is actually kind of nice.
The 2.1 speaker is a nice feature as well, and for TV speakers they are superb.
Finally the 6900 is way thinner, if you are wall mounting it you will appreciate the lack of depth.

Thanks for the info. I just got this a few hours ago. I did an extensive test between the LA7400 and this model. I did not see any noticeable difference in their performance. I asked the salesmen to demo Tangled 3D and Life of Pi 3D blu rays that I brought and they watched it with me. The salesman was honest enough to say that he did not notice any difference as well.

The only thing I'm sad about is that this doesnt have the de-blur option in its Trumotion settings. Do you have this setting? Can you please check your trumotion settings?

Loving this tv set. Mine has some noticeable backlight bleeding. Worse than my LS5700 but the PQ is a winner so Im not going to lose sleep on that.

That's awesome. I like me set as well, it has some minor issues but all in all it has great picture.

Are you using the ARC function on your TV?

Im using an LG HTIB 6320 with it. I dont think it has an ARC feature. I just oike the ease of use with it though. My htib turns off the same time as my tv.

Btw, why was local dimming bothering you?

Too bad that you don't have ARC. I wanted to know if anyone else is having ARC issues with their TV. This is the second LG TV that has given me ARC problems.
Right now I'm running the output via optical from the TV, ARC was working but then it stopped.

Sometimes when I watch TV and it goes from a bright scene to a dark scene I can see the TV dim. It will dim in gradual steps to the desired background lighting, and it is noticeable.
And since it's edge lit, sometimes there is bleed through, for instance if there is white text on a dark background you see this spot light effect shining the light towards the text.

Mind you these are rare instances of this, and it doesn't happen very often.
That and the picture quality is superb, so really the pros outweigh the cons.

EDIT: Seems that the ARC issue was at fault with my receiver, after a firmware update the ARC is flawless and performs really well.

Ha ha, what are you sitting on the fence about?

Looking at the specs they are very similar. The Sony has a thicker bezel and 2.0 audio, however it is 3" bigger.
They both use passive 3D which I like, and I'll be honest I considered trading in my LG to get the Sony.
However the only reason I considered the Sony is because it comes in 60" size.

Does anyone know if the 55la7400 stand fits on the 55la6900 tv? I lost the stand for my 6900 and found seller with a 7400 stand.

Since the manuals are the same for the 6900, 6950, 7400 and the displays are the same size, I'm going with yes.
