which board to replace after air input and one HDMI input not working

Oldturkey is certainly right. LG Tvs are known for having issues with their HDMI inputs. If after performing a hard reset on the TV and replacing the HDMI cables, you still have this issue, I suggest to replace your LG Tv Main Board
In order to order the right part, please get your TV model code from the back of your TV. It will help you to receive the right part.
