Philips 39PFL3088H/12 TPN10.1 E LA nu porneste


Recommended Posts

Buna Ziua!Acest tv philips avea 2 condensatoare umflate in secundar C9123 si C8112 de cate 470uF /25v .

Dupa schimbarea lor sursa ar vrea sa porneasca se aude un fasait pulsator ca si cand apar oscilatiile,Am 12V dar tensiunile mici apar si dispar.

placa este 715g6079-c0d-000-004k .

Unde nu am tensiune este  Q703 si U705 pe iesirile acestora.

Stiu ca pe Q703 trebuie sa am 5V dar pe iesirea U705 care este inseriat cu bobina L702 nu stiu tensiunea corecta.

Orice sfat este binevenit ,poate e o defectiune tipica acestor sasie.

Pe U706 am 3,3V acum ca am dat 5V acolo unde era lipsa adica pe iesirea Q703 ,dar tot nu aprinde ledul rosu.

va multumesc!
