Equipment is RTV 5040 Connected through a Motorola 2244, Comcast Cable: IR blaster stopped working to change channels. I checked the thread IR blaster regarding channel changes and got the cable box will turn on and the IR blaster is sending a signal to change channels. Channels change but not accurately. Using the channel guide to select a two digit channel number usually ends up being a single digit channel selection when the IR signal reaches the cable box. A three digit channel selection like 123 displays 111 on the cable box and goes to channel 1 Video on Demand. What suggestions could you have to help correct this problem?
