A:AnswerJust assembled mine (1/13/20) and noticed same side-to-side movement. Someone else noticed the stand being 'flimsy' and asked about other/additional legs or support. No answer/solution that I saw as of now. I don't mess with or move my TV much, but do make connection changes and was concerned that the stand connection might crack or break if moved some. Regarding the leaning, you may want to check to confirm you've got the stand pieces assembled properly. I needed to fiddle with mine to get the two pieces lined up. The stand connected to the TV just fine since it has a substantial cut-out it fits into. Hope this was of some help.
A:AnswerI don't know for fact -- I saw the same thing -- it's just 'newer' technology. It's roughly the same everything - but they refreshed it for the current year. If you can score a deal on the SK8000 - probably worth doing.
A:AnswerWatch it! with the stand, it is how I broke my TV because of the flimsy stand however if you have an entertainment center that is enclosed to slide TV in it it is ideal. LG has to design a better stand for this product that will allow the tv strong support but also narrower to fit on a smaller stand or cabinet.
