Samsung 32LE71B nu porneste


Recommended Posts

Acest tv doar clipeste ledul si nu face nimic , este compus din 

sursa BN96-03775A

MB GSM32SE

 

Am pornit sursa fortat si tensiunea pe PFC este 366v si nu porneste sursa mare 13v 24v 12v etc. deci sa inteleg ca tensiunea de PCF este cu probleme? va multumesc

Pe PFC trebuie sa ai 380-390v.

 

Asa stiam si eu, dar la acest tv daca este defect F9222L cred ca PCF nu mai urca tensiunea de 366V , eu lam pornit cu sursa de laborator si este ok, acum ramine sa fac comanda de ic. multumesc celor care au raspuns

 F9222L defect clasic la LE32S71B

Multumesc colegu, dupa ce am mai masurat miam dat seama ca acest ic este cu probleme, prima data credeam ca daca nu urca tensiunea de PCF mai mare credeam ca nu porneste sursa mare, si ca este de la PCF problema
