Incearca cu CNX82 ar trebui sa mearga.

CNX83 are si baza fototranzistorului accesibila, nu stiu daca e si folosita in schema. Daca nu e atunci merge adaptat un 817 si gata.

eu as fi de parere sa lasi sursa originala,este fiabila,ups001 are regim aiurea de functionare in gol

verifica d810,d812,q810,r828,inlocuieste c820,c830.c825 cu altele noi si ar trebui sa mearga

O sursă atât de fiabilă cum e aceasta cu STRS5707,trebuie reparată.O distrugi pentru un optocuplor.....:scarpin ...ti-a zis colegul Modoran mai sus să pui PC817,care merge,deoarece schema din LG nu folosește baza fototranzistorului.Acum am citit:"am 5V pe procesor".Sursa e bună,alta e beleaua.

CNX82 ce am zis eu potriveste perfect si fizic -are 6 pini ca si originalul nu 4 ca si PCul.Si eu zic ca nu merita acolo UPS001 dor in cazuri speciale.
