hi i noted that you are using an OMNI avr. If you are still using this, may I suggest that you have someone check the output. I have the same OMNI AVR, and when a technician tested the output, we discovered that the output is beyond 230 v, meaning it is not really effectively regulating the appliance connected to it. if this is the case, its better to connect to the 110 v output sockets (if the v of your electronic equipment is 110-240. Just a suggestion.
