Thank you for confirming.
This points to a hardware problem, meaning a faulty main board, which houses all of the hdmi input ports.
Hdmi circuitry is highly sensitive and easily damaged by power surges or even static shock from your body, if you've ever connected/disconnected anything while the tv or device was powered.
What we'll need to try here is a reset process:
Unplug power to the tv, and all devices, disconnect all hdmi cables between them
wait at least an hour
power all back on, connected to power only (no hdmi) for a minute, then power back off
power back on, tv first, source devices 2nd
Let me know the results.
