... TDA7563B 4.3 Output DC offset detection Any DC output offset exceeding ±2 V are signalled out. This inconvenient might occur as a consequence of initially defective or aged and worn-out input capacitors feeding a DC component to the inputs, so putting the speakers at risk of overheating. This diagnostic has to be performed with low-level output AC signal (or Vin = 0). ...

The others are notified after successive cycles of I This is true for both kinds of diagnostic (Turn on and Permanent). The table below shows all the couples of double-fault possible. It should be taken into account that a short circuit with the 4 ohm speaker unconnected is considered as double fault ...
