Sanatate ! Tv-ul sa defectat in urma unui soc electric ..   Am gasit defect in sursa  in secundar :  dioda redresoare de pe bara de 12V  .. si Tl431  care era in scurt... Dupa inlocuirea lor  tensiunile secundare sunt prezente  , ledul  de stand-by este rosu , dar tv nu pleaca din stand -By .. In secundar am  tensiunea de 5V stby   si celelalte doua de 5V si 12V le am pe diodele redresoare pana la mosfeti ...


Sursa este :  AY065D-3HF01 .. Si Main : JUG7.820.1283

As avea nevoie si de schema sursei daca se poate !  Multumesc !


Dupa mai multe sapaturi , am observat ca in secundar mai am o dioda redresoare pe care am o tensiune de 33v  care vine la o dioda zelner printr-o rezistenta de 510R   . am masurat dioda si este defecta .. Din pacate este SMD  si nu vad ce scrie pe ea  . pe placa are notatia ZD1 ..
