Does not turn on (LED off) | 5V DC DC power supply inoperative, Tsound is no voltage on capacitor CE4 (near the audio output), but tsound is 12V capacitor CE14 | Remove IC UE1 or coil LE1, adapt DC DC Mp1584 Step Down board or similar (input cap. CE14 and output in CE4), IMPORTANT: before connecting the output, adjust it to a voltage of 5V. Then just joy!!! | RUBERVAL SBC |
