tv everest model E21N-A8


Recommended Posts

Sursa trasnita. Am schimbat; dd5011 cu bu508, B764 cu 1013, 2sc 2655 cu2sc 3807, optocuplorul, tz. core comanda optocuplorul,doua diode  in scurt. Sursa porneste, toate tensiunilecorecte inafara de +B care nu vrea sa se ridice, in sarcina, decat pana la 85v Fara sarcina cu bec sau etaj linii, ajunge la 120v. Am verificat tot in sursa si in jurul optoc., nu vrea sa -traga- sub nicio forma. Poate-mi scapa ceva, ajutati-ma! Nu ar fi bun inlocuitorul lui DD5011? Multumesc.

 

 

Tv-ul foloseste multifunctionalul tda 11106/ps/v3/3

tranzistorul pus este bun.mai trebuie sapat.zenerele din sursa verificate la fel si conzii ceramici.acel 3807 este cu gaura de surub in el? condul de 100 de micro schimbatil din prima,din cauza arcului  electric format de la trasnet sigur a suferit,posibil si schoper-ul.
