Have the power supply checked or replaced, have it checked for leaky capacitors on the power supply board, there are capacitors on these PS that go bad causing bad audio and even dead symptoms. When these capacitors go bad there tops become puffy like they are going to pop.
So they should be very easy to spot. replace them with save value but instead of 10v voltage rating replace with same value but 16v working voltage.
