Orientation
  • This Sony receiver has a large number of circuit boards. The service manual has a diagram showing their identities and locations.

  • Because the unit won't power on, we're going to focus on the PS (Power Supply) board and the AC board.

  • Another thing to identify as a potential problem is the power switch, which has its own small circuit board behind the front panel of the receiver.
