I can't find a code to work with comcast cable using the emerson jumbo remote. I tried the codes listed for jaeks solution to the same problem, however none of them worked. Additionally, I have used the code search to try to find a code. I can successfully get the cable box to turn off using this method, but thats it... it will not turn back on nor change any channels. I am able to program the tv (GE brand), just not the cable.
