So I called the dealer, they gave me the phone number of the warranty company and said I was already registered under my home phone. I remembered that I was given a free 3 year extended warranty by the dealer. Just a quick follow-up: my TV is one month out of the one year warranty and LG wanted $100+ for the replacement magic remote. (I do have an extended warranty so in theory I can get a replacement remote - but I'd rather not spend an hour on the phone if this is a common problem.) Has anyone else had this problem with the remote - and if so, how did you solve it? Does the remote use bluetooth or WiFi? I sometimes use Bluetooth headphones with the TV and those work fine. The remote doesn't seem to require line-of-sight to work. I was also hopeful that a firmware update caused this problem and it will be resolved. Plus the cursor works fine, when I can get it turned on. I put in fresh batteries several times to see if that's the problem - it made no difference.

So that works, but it's not a good solution because it's hard to get the cursor turned on. I mostly make due by repeatedly pressing the button that turns on the teardrop cursor - after maybe 10 times it'll come on, and then I can use the cursor to operate the TV until it times out. The red light at the top of the remote sometimes flashes red, sometimes goes solid red for a few seconds, and sometimes does nothing when I press the button (I couldn't find a description of what the light does). It's not bad buttons, it's like the buttons only send the signal to the TV intermittently. It worked perfectly until a few weeks ago and I'm not sure what changed. The remote seems to work properly when the TV is first turned on, but later, I have to press a button repeatedly to get any effect. I have the 2016 LG OLED65E6P purchased with the 'magic remote' and recently, the remote control has become unreliable.
