I got my 60LA6200 from Amazon a couple weeks ago and I wanted to chime in with my findings:
+ Set has good color.
+ Nice adjustment options
+ Plenty bright
+ On the right content, picture can be fantastic
+ Game/PC lag seems low. I don't notice any in Game mode when I move my mouse.
+ PC desktop and text looks great
+ Screen is more evenly lit than the 5 edge-lit LG and Panasonic LCDs I tried previously.
+ Picture and motion processing seems good.
+ Passive 3D is the only 3D worth having for me and I've tried both.
- Black levels - They aren't great. But not terrible either. The edge-lit LG's I had tried before had local dimming so I knew this set would be worse and it is. Watching a dark movie like Harry Potter can be disappointing if it is a really dark scene. Keeping the backlight at 30 or less at night helps a lot.
- Screen tilts forward. When I put the base on my unit I could not get the top two screws to "bite" so I could screw them in. It's like they were too short to reach the holes. So my set is hanging on those two top pegs and screwed in with the bottom two screws. I don't know if this is responsible for the tilt or not but logically it could be responsible. But like I said, we couldn't get those screws to go in and tighten. This is not a huge deal
- Set has some minor light leakage or clouding in the lower left side. I realize this shouldn't happen on a rear-lit set and it is more diffuse than the edge-lit version but there it is. It's not nearly as bad as some of the others posted here, though. I can live with it and "massaging" this corner of the screen did help.
- The actual corners are slightly darker than the rest of the screen but this is better than the reverse on edge-lits.
- Banding: There is a slightly darker vertical band along the left-hand side about 3 inches wide. I'm not sure if this is really banding or some artifact of the way the set is lit. There are two smaller horizontal bands across the top. One about 3 inches down and another 2 more inches below that. Mercifully, these are thin and far enough away from the center of the screen that they aren't too bad. I can live with it.
- Dirty Screen Effect (DSE) - Sadly, it's pretty awful on this set. Any kind of panning shot across a light color (Fog, blue sky, close up of skin, light grass, etc.) will reveal that the entire screen is evenly peppered with little smudgy areas. I'm amazed at how even the uneveness is, if you follow me. Random looking, but randomly everywhere. There are even a few small areas about the size of the diameter of a pencil that are slightly brighter. What makes this worse is that you can play something like Skyrim and the screen will look absolutely beautiful for hours, and you'll be happy with the set. Then it decides to get foggy in the game and like a punch to the gut you're suddenly aware that in these circumstances the PQ is AWFUL.
- LG couldn't make an even panel if their lives depended on it. This is my 4th LG set in the past year looking for a new TV, so I feel I can judge.
- There is no "great" TV for me at reasonable prices. The quality control now just stinks. I've tried Sonys, Panasonics, etc. I've tried Rear Projection, LEDs, and Plasmas. They all have problems and each set you try will be both better and in some ways worse than the others. Will I return this set to Amazon? I still don't know. Despite the DSE, it IS the best one I've tried, all things considered. I know the perfect set doesn't exist and yet I feel compelled to hunt for it due to the $1500 investment. But every exchange is another roll of the dice and I've ended up with sets that were worse and regretted it. I wish I wasn't so OCD about this crap.
