Beocenter 9300 with beolink 1000. The remote stopped working. After trying everything, taking apart, checking connections, changing batteries of course, no luck. Finally put the remote directly against the receiver on the 9300 and it worked. If I pull it away by an inch it won't work. The question is, is it the remote or the sensor on the 9300? I would buy another remote but hate to do that if it is a problem with the 9300 instead. Does anyone have any ideas for testing???
