Hi. I have an Apple TV 4K, the first generation, I think, from early 2018. I use Netflix on it a lot. Lately, when I start a movie or episode, the TV will suddenly shut off in a couple of seconds. I turn the TV back on (using the Apple TV remote) and start the show again. The TV shuts off again. This will repeat 3 or 4 times until it finally stays on for the whole show. Anybody know why this happens, and is the problem with the Apple box or the TV itself? Any help is appreciated. Thanks.
