When I got Comcast X1 wireless cable box, it had to go in the HDMI 1 slot on my TV. I moved my Chromecast dongle to the HDMI 2 slot, but the TV doesn't recognize the slot, though my iPhone can connect with the Chromecast.

You may have to activate that imput through your menu.Alot of plasmas have the ability to mute imputs.
SOURCE: Need help hooking up TV, BluRay, Home Theatre & cable box
I found that since the Panasonic TH50PZ80U TV has only 2 HDMI ports on the back of the TV, the best solution for me was to use component (red, blue, green) cables to connect the Home Theatre to the TV. I suppose I/you could connect the home theatre to the HDMI port on the front panel, but I don't want cables hanging out the front of the TV (personal preference). Unfortunately, I am no longer able to use the VIERA Link functionality available by connecting all Panasonic components to each other using HDMI cables, but I feel it's a small price to pay for the incredible picture quality acheived by using the HDMI cable to connect the HD Cable Box to the TV. I may yet be able to control everything using the HD Cable Box remote, but I haven't gotten that far yet but I've got Comcast coming on Saturday and hopefully they can let me know if this is possible: let me know if you have a solution.
So here are the components and the cable types used to connect:
I hope this helps someone else.

I had the same problem. I changed the 4-3 setting on the motorola cable box. Turn off your cable box and press menu. My 4-3 setting was set to auto. If you turn it off, you lose the 4-3 aspect on most channels. I changed mine to 480p and so far it seems to be working. Worth a shot.

Try this combination.
1) Start with the cable box turned on and TV on tuned to the cable box.
2) Press the POWER button for the cable box and then quickly press the MENU button.
3) This should bring up the user setting menu. Use the arrow keys on remote to go to Closed Caption and press right arrow button this should bring up the closed caption menu.
4) Press the OK button and this should either turn CC on or off.
5) Once Closed Caption is turned off press LEFT ARROW button to return to User Settings Menu.
6) Press the POWER button to turn the Cable box back on and the Closed Caption should be gone....
Good Luck.....
