    7.1.3 HOW TO DIAGNOSE THE UNIT WITH THE POWER AMPLIFIER SECTION REMOVED Purpose: When repairing this unit, the large Heat Sink Block obstructs access to some Assys. If the Heat Sink Block is removed, as the posistor mounted on it is also disconnected, the protection circuit is activated, which disables failure diagnosis of these Assys while the unit is powered.
