Orion sasiu 11ak58

Recommended Posts

Acest tv are sursa cu NCP 1207 si scoate tensiuni mai mici decit cele nominale(U1 85V in loc de 112v).Am schimbat optocuplorul,referinta TL 431,am verificat toate rezistentele din zona lor,toate sint ok,am schimbat de asemenea toti condensatorii de pe iesiri.Un sfat ar fi bine venit.Multumesc.

Verificati grupul de rezistente R842, R845, R846, R839. Cea din urma este critica R839-99k.Scoateti cate un pin, nu masurati rezistentele direct in circuit.Scoateti apoi din circuit finalul linii/Q603-BU2508, montati un bec cu incandescenta (220V/40-60w)  intre  colector/emitor si masurati B+.

 

PS: Inca  odata verificati rezistenta R839-99k.

Tv-ul este cu diagonala mica tensiunea U1 dupa schema pe care o am eu trebuie sa fie 112V,finalul linii este de conectat,sursa este pe bec,rezistenta de 99k afost schimbata,celelalte rezistente sint SMD masurate in circuit cu un multimetru Philips 2524 arata exact valorile scrise pe ele.Multumesc pentru interes.

Mii  de  scuze, asa este.  B+  are  valorea de 112v,  eram   cu  gandul  la   alt   sasiu!

Inca  odata  mii   de  scuze pentru greseala.

Verificati  toate   rezistentele  mentionate  de   mine   mai   sus.
