Power button and up volume buttons work on side of TV. No other buttons work. Can use remote to change everything on tv.
SOURCE: Lost remote want to get to input channels using side buttons on TV
Try using the manual buttons and keep pressing channel down until you see the lowest station you receive, then go slowly.
Maybe Insignia put the inputs into the channel search automatically.
SOURCE: cannot turn tv off with power button or remote , must unplugpower
It could be a stuck button on the set. check to make sure they all feel the same.. If one don't feel right try to free it .. If a button is stuck it wont let any of the others work or the remote.

It sounds like it has main board problem, leave it unplug for about an hour to let it reset itself to see if it will work again. It can also be unstable power supply problem.
