No audio, sometimes the audio came back, said the customer | Defect in the power supply, 3.4 turns was 1 volt, I made an adaptation of a regulator IC taken from a 3.3v scrap board, in my case I put a 1084 33, It's easy, pin 1 is ground, pin 2 It's the 3.3v output and pin 3 on the right It's the input, you can solder wires to the regulator and connect pin 1 to ground, pin 3 in the middle of the d 209 (6volt rectifier diode) and pin 2 (in the middle of the regulator) on the 3.4v output of the p203 connector that goes to the main board, note: you do not need to disconnect the original regulator circuit from the power supply board, leave it as it is | reginaldo moronte,eletronica junior caldas novas |
