I'm guessing a power surge from the returning power burned something up. You should have all your electronics plugged into surge protectors at a minimum. The best protection is a UPS (uninterruptable power supply).

Contact the authorized service center for Sansui.

Is there a button labeled source or input? That is the one you want. If not, a universal remote for $15 to $20 may work although it is hard to tell from the box if will control the source, so buy where you can easily return it, say Walmart or Kmart.
