you can try removing the batteries from the remote and waiting a few minutes and then put them back in. You can also unplug the box and then plug it back in to reset it. Lastly you can reset the remote back to factory default, see below.
This reset will delete all macros and keymoves. It will not reset device codes.
1. Press and hold the "Setup" key until a device key blinks twice. 2. Type in the code 980. 3. If successful, a device key will blink FOUR times.

do you have any ambient light in your room? does your tv have one of those back light things? certain flourescent lighting can do it also. Turn your room dark and go close to the box to see if it changes anything.
I also am having this issue. Went an got a brand new remote and same thing. I have done all troubleshooting remove batteries, tried all codes in this thread and still nothing. The remote will mute and control volume but will not change channels, access guide, DVR or OnDemand. Any suggestions for me?
"The remote normally is delivered by Comcast with the Cable setup code locked. You can check that by watching the LED. 1) Tap the Cable device button. 2) Hold Setup until 2 blinks 3) Enter 01877 The remote should blink twice. If it doesn't, and instead gives one long flash. then probably the setup code is locked. Unlock it by: Tap the cable device button 1) Hold setup until 2 blinks 2) Enter 982 The remote should blink 4 times. If it blinks 2 times, do steps 1 and 2 again.
Now try assigning 01877 again.
Oh, and is the OK/Select button red? If it is grey, then the setup code should be 4 digits-- 1877."
