Having just moved to Comcast for cable TV I have discovered that the captions feature on my TV does not work anymore. This is because the HDMI cable between my set-top-box (STB) and my TV cannot carry closed captions for the TV to decode.
The problem is that there is no way to enable captions via the Comcast on-screen menu system.
It turns out that you have to turn of the set-top-box to enable captions – so it is not terribly convenient to turn them on and off anymore. This is the button sequence on the Comcast remote to enable or disable captions:
- Press the Cable button and then the Power to turn the STB off.
- Press the Menu button (on the STB).
- Press the Down Arrow button until you get to Closed Caption option and then press OK to enable / disable captions.
- Press the Power button twice to turn off the STB off and on again.
