Probleme cu un BLUEsky ST7216 sasiu 11AK19PRO


Recommended Posts

Va salut !Am de reparat un Tv BLUEsky model ST 7216 cu sasiu 11AK19PRO . Am gasit pe E-W dezlipita si facuta zob dioda dinspre masa , si finalul linii de asemenea , ars . Am schimbat dioda si condensatorii din jurul ei . ?Am dat un plus ? pe st-by si am pornit sursa cu un bec . Dar pe dioda D317 nu am decat 10V si de aici pe stabilizatorul LM317 nu am decat 2,5V si 1,7V in loc de 3.3V si 2.5 V . Dati-mi va rog niste sfaturi cum sa abordez mai departe lucrul ... Va multumesc

decupleaza pe rind barele' de alimentare.....

Cand am dat afara finalul de linii nu m-am uitat ce tip e , am pus dupa shema un BU2508DF . Din greseala am vazut ce scosesem un 2508AF ...... Acum am fost convins ca s-a mai umblat in el .....Am schimbat si dioda de pe sursa de 3.3V , am pus toate la locul lor si i-am dat drumul .....functioneaza !!!!(cu 2508DF de bine'nteles ) Multumesc ! Cu stima ,
