The remote was working perfectly, and then I wake up this morning and it no longer works. I have changed the batterys powered on and off the box. Ive tried holding down the cable button but nothing happens. The lights will blink on the top bottons but nothing happens when you hold them down. Any ideas of the problem?
Nope, just a little motorola box. I found it hard to believe that a remote control would just stop working for no reason but after doing some research, comcast readily admits that they have terrible equipment. But to not be able to change the channel using the box is a joke to me.
Thanks for the advice about checking the "backlight" setting on the television screen. It appears that my brightness was interfering with the IR of the remote. I wish I had come here first, rather then Comcast's "ONLINE LIVE CHAT" since after over an HOUR AND A HALF and thier only solution to send out a tech, as I certainly wouldn't be up at 4 am. Your solution fixed my problem in less then TWO MINUTES...... Cudo's to you. I hope that Comcast will add "checking the television monitors' settings" to their trouble-shooting checklist......The highlighted in blue below really would have saved all involved both hassle and time.
What cable box do you have?
Do you have another Comcast remote on another box you could try?
If you have a DTA, you can try the remote IR receiver that comes with the DTA to plug in the back of the box and see if that helps, either to test or a permanent solution.
See if it responds with the TV off. It could be light polution from a CFL lamp or the backlighting on the TV.
