Dear members, my Beocenter AV5 has developed a strange fault. When I turn it on, it doesn't stay on the selected source, but rather randomly switches between various sources. For example, if I select CD, the Beocenter goes to CD for a couple of seconds, the CD starts to play, but then, without me doing anything, the Beocenter switches to V.Tape, just to go to TV briefly afterwards. When I press CD again, it doesn't stay there, but rather jumps to TV again or something else. Sometimes, I can use it normally for quite some time (an hour or so), but as soon as it starts switching sources, it doesn't go back to normal. Only if it's off for a couple of hours, there is a chance of it operating regularly again for some time. The Beocenter has 300 something Video Days on it, and otherwise works perfectly. Any idea what the reason is? Maybe a defective capacitor? But if so, where? Thanks! Kai
