My Comcast remote which had had non-working buttons for awhile finally gave out today, not sure when I'll be able to go get a replacement, so I'm trying to program a Radioshack 7-in-1 15-135 universal HDTV remote to operate my Comcast box and my SHARP LC-60LE632U TV but have had no success so far. I have a PDF of the remote's manual, and have tried using all codes for Sharp TVs listed, none took. My box is a comcast motorola DCT3412 I HDTV DVR and I tried all codes for Motorola boxes listed as well as General Instrument codes and none of those took either. I tried the find your code function, but after cycling through the button 200 times neither device would power off. Anybody have any ideas?
