Looks like you have a problem on your integrated circuit. I suggest you take it too repair shop.

If the unit does this without anything connected to it then it does need to be serviced.
If not then check your speaker wiring for any shorting connections. If you don't see anything connect each speaker one at a time and see if it happens.
If it does either the wiring or that speaker is bad.
If not then connect each source one at a time. When you connect the source that is causing the problem that source or cable is at fault.
