I just received a new Cox Communications HD/DVR Motorola DCH3416 box. Since installing the new box I have noticed issues with the remote control interacting with the cable box. I cannot change channels for the life of me. I originally thought I had a bad remote and had it replaced with no change. I had Cox out to my home two different times to replace the box and the remote again...still same issue of not being able to change channels. I came across some rants about IR interference and thought perhaps this could be my issue. I experimented by turning my tv sideways and believe it or not the remote worked perfectly. I turned the tv back and the remote stopped working. I've concluded that the tv is the issue and is producing high IR noise which is affecting the remote to dvr box signal.
Is anyone else experiencing this issue with the PN51D450 model. I am looking for a fix to this problem.
