When I revamped my A/V system I routed the HDMI out from my cable TV set top box and from my wireless Bluray player to a 2x2 HDMI switch, so that either TV can select either HDMI source.
That HDMI switch also has IR repeaters, so I put an IR receiver under each TV and an IR flasher in-front of the Bluray player and in-front of the stereo head unit. Both are hidden behind solid doors.
The cable TV set top box has a RF remote control, so it is good hidden behind a screwed-on panel.
All of those electronics are powered by a hidden inverter w/ a small control panel that is easy to access in-case power needs to be cycled when things get confused.
Most current-technology televisions are Class II double-insulated AC-powered devices. It is good to swap out working televisions every few years because of improvements.
