Can anyone help? I keep hearing a 3 second high pitched beep but can't quite tell where it is coming from n our lounge where our home theatre system is, i.e. LED TV, receiver, speakers, blu ray player, modulator, router, Foxtel box and modem. There are a couple of cable connector boxes behind the system also. I thought it was our fire detectors but I took out the batteries and I could still hear this beep lasting about 3 seconds every 15 minutes. I unplugged the power for the TV and waited 15 minutes - I could still hear the beep. I unplugged the router - still could hear the beep. I unplugged the Foxtel box - still could hear the beep. I unplugged the receiver - still heard this annoying beep.
Any ideas?
