That's a tough one, I've had the same TV since I was 4 (17 now). It's probably exactly what your friend is looking for (no internet connection, has ports for HDMI, SCART, and the red-white-yellow cables), but it's pretty old so I don't imagine it's being sold anymore.
It'll break at some point, despite my wishes, so I'll end up dealing with this question soon enough
Does Lemmy have a version of the remindme bot?
