Problema Philips model 32PFL3403/12 sasiu LC8.1ELB


Recommended Posts

Va salut!

Dupa cum spune si titlul topicului am un Philips (pe sasiu LC8.1ELB sursa PLCD170PS09 si invertor 6632-0494A ) care initial a fost supus unei supratensiuni de la retea. In starea actuala Tv-ul porneste , are sunet insa nu lucreaza invertorul (nu pornesc lampile) . Am verificat tensiunile de alimentare ale invertorului si sunt in regula, partea de On-OFF de asemenea.

 

Driver-ul invertorului este de tip BD 9897FS iar tranzistoarele FDD 8447L.  Driver-ul am observat ca se alimenteaza  (pe pinul 26- am 24V).

 

Rugamintea mea este sa imi spuneti ce mai pot verifica? sau pe unde sa mai sap. Orice sfat este binevenit.

 

Va multumesc anticipat!

Cu stima!

Lampile sunt in regula, iar valorile rezistentelor sunt aceleasi (insa cam mici 0,2-0,4 Ohmi).

Dl Lucian unde pot gasi revista ?intrucat am vazut pe site-ul unde se comercializeaza ca momentan personalul este in concediu si nu expediaza nimic in afara de module LCD.

De asemenea as dori sa va intreb daca stiti unde pot gasi mai multe date despre trafo ? cu inscriptia de pe ele  (L1-EH32-A-08715F-BJ-0) nu am gasit nimic.
