Circuit sursa MP3 player

Recommended Posts

Am un mp3 player cu CD, Miyota X-999DX.

Este dintre acelea ieftine, care au telecomanda, redare VCD.

Are o functie de incarcare a acumulatorilor, cu un comutator "charge on/off". Cineva a pus baterii si a dat comutatorul in pozitia on - incarcare. S-a defectat circuitul de alimentare. Din ce am reusit sa observ pe cablaj, acest circuit realizeaza alimentarea tuturor blocurilor functionale ale aparatului, inclusiv comanda motoarelor. Bineinteles, incarcarea acumulatoarelor era realizata de acelasi circuit.

Intrucat nu am gasit nimic despre acesta, postez aici denumirea si sper ca cineva sa stie ceva despre functionare, pentru a-l inlocui cu altceva sau daca pot cumpara de undeva:
