Not shure how you switch between inputs. In case it is by using remote control try new batteries. Also when batteries are inside forever they tend to leak at some point so check that out once a while because replacing a remote control of any device can be rather expensive...when trying to sell because of such issues TV is worth less.
These days lots of folks use AV receiver so only one HDMI input is needed, even so not looking forward to a TV with only one HDMI input being accessible.
