I have Comcast cable and can not get the remote for the cable box to turn off my TV. It works to turn channel and for the volume but not the on and off.

when i turn on my flat panel tv the light turn on but the tv don,t come on.

The Comcast remote only changes channels on the cable box. not the tv itself. If you have a cable box then the tv will need to be turned to channel 3 or 4.

your rca does it have a button for cable. then you can program your tv remote to work with the cable box. go to the manual and try all the codes for rca tv. if this does not work then you have to try it manually. have them give you a different adapter. it might be in the box or remote.

your tv needs to stay on the same channel for the cable box to work with the tv and you change the channel on the cable box not directly on the tv

Usually on a universal remote (after programmed) the volume is controlled by pressing the cable button then adjusting the volume. When you turn your tv on by pressing tv power---then flipping through the channels by pressing cable--channel up or down. The remote (in my experience usually only controls the volume while in the cable mode)

I Believe You Can Go To Channel 2 And Right Below Those Channels Are The 3 Video Channels Turn On Your Dvd Player And Go Through Them. If That Doesn't Work Try Looking At The Buttons On Your Tv For A Tv Video. Make Sure You Dont Have A Tv Video Button On Your Remote If You Do Then Just Click It Till You Find The Appropriate Video Channel.

put new batteries in them,contact comcast and get a new remote for free

I have a Motorola DVR from Comcast. Code 051 will make all the cable functions work. Haven't figured out how to do anything with the DVR bits,

Need to program my Insignia TV to my Direct TV remote. Need code

Are you using a cable box sush as a Comcast cable box? If so then the volume control within the cable box is most likely not high enough for the TV to detect a stereo pilot signal. The Comcast remote (if thats what you have) still is programmed to operate the volume within thier box, the volume display will be at the top of the picture and it will be in white. Turn it up until the word "stereo" appears. then leave it at that setting and use your TV's volume control only.
