Does anybody has this schematic? My Bose Wave Music System (CD upload from front, not on the top), is not sending the CMOS level to the STDBY of the power amplify TDA7376B, and even if I force the TDA7376B to arm injecting 4.5V on the PIN 7 still not sound (just a glitch because if the power injection), so something before, maybe on the selection input section or volume/EQ control
This board is that one the use the capacitor 0.3 5v to keep the information, not 9v battery

I appreciate if anybody can help
