I bought the QN90A Neo QLED, and I'm already starting to regret it.
There was a plastic cover in the package which I connected it on the back side of the TV (where it reads common interface).
I can no longer remove the cover. It's stuck indefinitely.
What's the purpose of the common interface? And how can I remove the cover?
