MITSUBISHI CT2153STX TV D pdf

sursa la pag 33-34

acest tv imi da batai de cap,in sensul ca sursa aux=ok insa sursa principala nu pleaca

am 300v

inlocuit ci sursa,verificat cei 3 tr q901-954-955-ok,comanda on/off ajunge la optocuplor,si acesta inlocuit

am banuit supraconsum pe trafo linii,l-am inlocuit,la fel,BU-ok,am decuplat liniile,am pus bec....si la fel

are sursa asta vreo chichita?am avut in timp cateva exemplare la reparat dar au avut alte defecte!

multumesc anticipat

tranzistorul regulator din STR59041 , se masoara?

si cele 2 rezi de 180k , care alimenteaza Q955 sunt ok?

Am avut ceva de acest gen, la Panasonic (sau Toshiba ,nu imi amintesc bine) sursa tot cu STR59041 si m-a "plimbat" o rezistenta cu pinul oxidat in lipitura  de "mi-o venit rau".STR-ul e "vero"?
