New cable box

Is it possible for a new cable box's HDMI output not work
But the cable output works? Ive tried 3 different HDMI wires and still doesn't work but the old cable output to TV works

Re: New cable box

Sure that can happen. The different components of the cable box aren’t connected. Somebody dropped the ball in quality control
