Need to turn off closed caption on tv remote it's a toshiba DCSB1

Closed Caption may only come on when you have the television muted.

I had the same issue... here's what I did.  If power off your cable box, then press the menu button, there's a selection to enable or disable Closed Captioning.  This works for both HD series Motorola boxes Comcast offers, at least in the Minneapolis/St. Paul area.  Hope this helps!

I had this problem just now for the Toshiba DC-SB1 remote control model, and I think the problem might be that you're pressing the wrong button. Try pressing the "skip track" button right below where it says close caption on the remote. It's deceiving because, based on where the words 'closed caption' are, it looks as if the stop button is associated with it, but it's not. That's what I was doing wrong, it may be a different problem for you though.
