Recommended Posts

Buna ziua.La ac. tv sasiu CP195 cu sursa defecta (STR6753 explodat-supratensiune) am pus de proba UPS001, care a cedat imediat-am zis ca a fost proasta sursa, am inlocuit d809 si c813, si am pus alt UPS cu care tv-ul a pornit si a functionat OK, tens. normale. Aseara l-am oprit si astazi cand l-am pornit a bubuit iarasi UPS-ul. Ce ar putea fi?cu stima!

schimbati toate diodele din puntea de redresare,precum si condesatorul 100-220mf 450v,lasa-ti in aer pinii din primar ce nu-i foloseste ups001,daca bubuie doar siguranta,da-ti afara si ptc si bobina de demagnetizare,de proba,e posibil sa fi fost afectate de la socul de curent,deobicei de la socuri de curent,gaseam un c fix la 2kv pe langa trafchoper defect
