Sursa TV Samsung LE40EH6030


Recommended Posts

Salutare tuturor!

Intampin urmatoarea problema cu acest televizor: Sursa PSLF930C04D nu porneste din stand by, inlocuit ICM803 , ICM801 sursa pulseaza ca si cum ar vrea sa porneasca.

Inlocuit electroliticii din circuitul FSFR1700, verificat restul condensatorilor si in mare componentele sa nu am scurt pe placa insa nu am gasit nimic dubios.

Are careva vre-o idee referitor la aceasta problema sau o schema, am cautat pe net insa fara succes!

Nu am gasit schema PFC-ul porneste dar nu se stabilizeaza, oscileaza odata cu restul.

Tensiunea de stand by 5v este stabila, singura de altfel.

Circuitele integrate ce se afla pe placa le-am testat pe o placa cu aceleasi componente si sunt functionale.

 

Acum 7 minute, Florinel TV a spus:

Sursa este BN44-00552A si gasesti schema aici https://www.electronica-pt.com/esquema/lcd/bn44-00552a-psu-37327/

 

Mersi Florinel, scrie ca este BN44-00552A dar de fapt este BN44-00473A asemanatoare ce-i drept.
