Can't change channels on television or by remote

I have a NS-26L450A11 television. I am unable to change channels using the remote on directly on the television. When I press the channel button on the remote it displays a gray box with DTV where the channel usually is.

Hello tanya,

Welcome to Community@Insignia™!

Please try the following and let us know your results:


  • Remove the batteries from your remote control, press all of its buttons, and install fresh batteries.
  • Restore your TV to factory defaults via the on screen menus.  Remember: if you have customer picture settings to make note of them before the reset!
  • Power-cycle your TV by turning it off and unplugging it for an hour.
