My remote is not working. I removed the batteries and put them back in to try to reboot the remote without luck. I also have tried fresh batteries. All I get is the cable light (on the remote) blinks twice and then the TV light starts blinking without stopping. I really don't want to go to the Comcast office to exchange it. This is becoming an every-four-months occurrence.
I had the exact same symptoms you did last night and I tried everything to fix it. Then I noticed a stuck up arrow key. It was stuck under the metal ever so slightly I had a hard time seeing it. I freed up the key and it started working like a champ. Try closely checking your remote for a slightly stuck key. I hope this helps you.
Thanks for the information. The remote is the silver one with the grey OK/Select button. I had the batteries out overnight and had no luck with it rebooting. I also tried the reset in the link you sent me and I wasn't able to get to the point where pressing the setup key had any effect. Again, thanks for the tips.
Thanks for the troubleshooting tip. None of the buttons seemed to be stuck. I went through all the buttons with the batteries out and all of them seemed to be working normally. I guess I'll stop by Comcast today to exchange it.
I had the same issue and discovered one of the keypad buttons stuck just a little bit under the remote cover. The way the remote "thinks", that button is constantly being pressed, which is why the Cable light stays on. Once I freed the stuck button, everything returned to normal.
