I have a haunted TV: my 4 year old Sony Bravia (Android TV) reboots seemingly intentionally during the most interesting parts of TV broadcasts. And since a few weeks ago, it also regularly loses the Wi-Fi connection. Thanks Google and Sony!
Usually the culprit is aged electrolytic capacitors.
Mine had cold solder joints on the bridge rectifier.
I had a bad experience with the last (and final) cheap Android TV I got (Philips, really a rebranded FUNAI according to the Netflix device ID) - would take minutes to boot, often not power on unless unplugged, and would get slower and slower the longer it was on. Guess it was haunted as well. I left it in the house I sold.
Ah, a classic case of haunted tech. My version is my electric bike that decides it wants to turn the power on and off as it pleases.
My Samsung TV remote used to stop working once a week, every week. The only fix was "rebooting" the remote by popping the batteries out and back in.
Our Google Chromecast tend to become very hot and then restart when the kids watch Disney+.
wow I also have a Sony Bravia around the same age and this also happens to me sporadically! drives me insane when it happens, but it's infrequent enough that I haven't replaced it yet.
Beware. Newer TVs are haunted with so many persistent smart features that you might miss the Bravia
