Ma intereseaza si pe mine cu ce pot inlocui componenta notata cu U4 de pe placa de baza  T.VST29.A2B 12062  capsula smd 5 pini sot23-5 cu inscriptia GG2G  .Banuiesc convertor 5v to 1.2v cu  stby . Eventual un manual service aferent sau  asemanator sasiului.

Va mulțumesc domnule nostrom pare a fi exact componenta de care am nevoie.Pentru domnii :am prezentat foarte clar tipul de capsula , inscripția de pe componenta cat si șasiul echipamentului , dar cred ca voi și acum va jucați cu EFT uri.

MCP16301 are 6 pini  nu 5 ...am precizat tipul capsulei . 

Circuitul este fara indoiala BL8024  am studiat schema  , dealtfel in lipsa componentei am  improvizat o noua sursa pe baza unui circuit  din seria MP si functioneaza perfect .
