Remote loses some programming functionality after a few minutes
I was using a new Comcast XR11 remote on my Visio TV for 6 months with no issues. Recently the on/off and volume commands stopped working. I reprogrammed the remote and this functionality started working again. However, after a few minutes the volume and power commands no longer worked. All other remote functionality was fine. I reprogrammed it many times, trying all the codes, but nothing resolved it. I spoke to Comcast customer service and they suggested a new remote. They initially sent the XR2 remote by mistake. That had the same issue. I then got a replacement XR11 remote and still have the same issues. I have rebooted the mini-box and that did not help either. TV works fine.
