Dear P20 experts, I’ve been running my P20 for 3 years now with no problem whatsoever. I power it down via remote control and wake it up with it. I have time delays for the various zones to start gear sequentially. Yesterday I powered it up and it initialized the first zone successfully, when it c…

Does this happen when powering zone 2, or just the first time?

Dear jvvita, It happens right after flicking the main switch at the rear. The initial problem occurred when powering zone 2 but after that it now always happens just seconds after flicking the main switch, even without any gear cables plugged into it…

Dear 1cdfoley, Thanks a lot for your solution proposal! I’ve tried powering the P20 up with no hifi gear attached to it at all and the reaction of the device is the exactly the same. Hence, the problem can’t be invoked by a faulty device provoking the P20. However, your advice sparks an idea with…

Maybe you could try plugging a high load device (toaster or hair dryer) into the same wall socket to see if the in wall breaker may be failing. Not saying this is the problem but that test should eliminate the in wall breaker.
