monitor lcd yacumo nu se mai aprinde


Recommended Posts

Buna seara, am facut cateva masuratori pe placa , cred ca este sursa defecta. Am masurat intra 220Vca, sunt redresati undeva la 295Vcc, condensatorul este bun ,la iesirea trafului din sursa nu am nici o tensiune. am masurat in sursa tot, condensatori, diode, tranzistori sunt buni. A mai ramas un integrat smd I07575PS care nu am gasit nimic despre el.

Nu prea ma pricep la surse in comutatie, dar as vrea sa invat usor, usor.Orice sfat este bun. Multumesc!
