New set up which works sporadically - no method to the madness.
Cable box turns on using ALL button but not TV. Small grey box shows up after you turn on TV stating: No Signal, Press INPUT on your remote control, then select the device you want to view. When you press INPUT, no choices appear on the screen. (TV power is on.) If you press the TV button on remote, sometimes it works but most times, not.
Ideas? This is the odd box out of the boxes at home. Spectrum did not have any of the other boxes which work fine elsewhere in the house.
