Sony equipment of that era was afflicted with the infamous SMD aluminum round can type electrolytic capacitors. They are well known to fail by leaking the electrolyte attacking the components and copper traces around before going dry and dead.

The later revisions of these model use two or four of these caps that usually need to be replaced.

That was the case with my unit where the 47uF cap have leaked. I decided to replace all four capacitors. 

The radio was working before the repair, but I noticed an improvement in the sound quality after installing new capacitors.
