When diagnosing power loss on the board, trace 12V from the input pin to the internal voltage regulator IC. The regulator should step down the voltage to stable +5V and +3.3V rails to feed the main microprocessor and RAM modules.
This is the most referenced part of the manual. The RD3 01 uses two main ISO blocks (A and B) plus an antenna diversity connector.
: There is a documented factory design error in the AUX input circuitry. An electrolytic capacitor connected to the IN- input of the TDA8579 chip is often installed with reversed polarity . If you are adding an AUX input and hear distortion or noise, you should flip this capacitor so the positive terminal faces the TDA chip .
: There is a factory defect where the electrolytic capacitor for the IN- input of the TDA8579 line receiver is installed with reversed polarity . If you use the AUX input, this capacitor should be re-soldered with the positive side toward the TDA chip to prevent audio degradation.
