HDMI Connection

When powering on my tv I get a no signal message. I have to switch to hdmi 2 and back to 1 and it connects.. All my other devices connected by HDMI come right on. It is just the Xi tv box. I have switched cables , HDMI ports etc. with no luck

Re: HDMI Connection

There might be a solution depending on how you are connected.  Does your TV's HDMI por use ARC? What are the Device Settings in the Settings menu?  And  in Comcast Labs what is HDMI link set to?

Check if the box has power preferences on. If on your box may be asleep and pressing channel up wakes it up.
