The Samsung's remote control is not programmable for the cable box. I wish I had a more elegant way to say that, but it's short and to the point.
I've seen that issue several times, and I'm not sure why it only changes one level at a time. Your best bet is to contact Comcast and see if they have an updated code for this model.
I'll look into this on our end and see if there's a solution posted somewhere internally.
I have a Samsung 37" 550 series LCD tv and Comcast digital cable with a Scientific Atlanta cable box and Comcast DVR 3 Device remote. I like the Samsung TV remote with its big numbers and backlit display. Is there a way to program the Samsung remote to operate the Comcast cable box?
If not and I have to use the Comcast remote to control the TV, does anyone know what code to use where the volume control will function correctly with the Comcast remote? Right now when I press volume, you have to keep clicking the volume control to increase/decrease the volume as it only will change one bar at a time. I've tried all the numbers listed and even one I found through this board, but although I can operate the TV, the volume control doesn't work right.
Any help is appreciated.
