I disconnected everything but still it is going back to standby mode when I turn it on
That is a sure sign that it has internal problems.
You may be in Protection Mode. Some manufacturers design their AVRs to flip into this mode when a fault is detected. When this happened with my Marantz AVR, I needed to see a tech. I'd call HK andsees iff there's a user enabled solution.
