Hey there... My TiVo's two LED lights have gone out and the IR sensor seems to have broken today. The remote/batteries still work b/c I can still use it to turn on my TV and to change the volume. When I turn the TV on, I am at the mercy of whatever is on Live TV. I do see the TiVo continuing to change channels (and display the channel header) correctly at the top of the hour as it goes about recording shows on its to-do list. I just have no control of accessing TiVo Central to view shows, change any settings, or really doing ANYTHING with the remote. How do I fix this or further troubleshoot the problem? Can I just replace the IR/light assembly or something? Thanks for your help!!!
