A few days ago my TV announced it had new s/w to download, so I let it do its thing and upgrade.
Maybe that was a mistake. Yesterday I came in to my man-cave and the TV was on, no signal. That is odd for two reasons: (a) I turned it off the night before, and (b) it turns off after a while with no signal (or used to).
I assumed I was being silly. But this morning the same, and I was suspicious.
Later during the day I popped out today for a coffee, and I definitely turned the TV off when leaving. My wife saw me do it - I am not going crazy. When I came back, there it is, on, no signal.
So I did a test - I turned off the TV.
It turns itself back on!
It also turns on the (connected) Apple TV (as I would expect), and after a while the Apple TV goes off leaving the TV on with no signal. It stays on!
I can only assume this is LG's latest "burn up your OLED pixels quickly" software update. I can't think of any other reason they would do this. Very annoying. Not quite sure what to do - the power socket is an option, but annoyingly all hidden behind the cabinet, and rather tedious to say the least.
FYI I went in to menus and it has "turn on by WiFi" and "turn on by bluetooth", both of which I have disabled, but no different.
P.S. Disabling the simlink stuff "fixes" it, but why was it suddenly broken. It was fine before. Arrrg!
