My cable box is connected to my Samsung TV with HDMI via source 1. Now all of a sudden, i get no picture or sound.Using my remote to turn on my devices, the TV turns on, the Cable box turns on and so does my audio receiver. But nothing shows up on the TV. I have doubled checked my in/out source, but still no response from the cable box. Any solution would be appreciated. My cable box is a Pacer,with the extender hard drive.
