circuit 36A65 sursa Toshiba 32E2533D

Recommended Posts

Mi-a venit integratul,am pus si apar toate tensiunile  dar ledul rosu nu se aprinde.Acuma am observat ca una din tensiunile ,mai exact 12V pentru placa de baza trece printr-un FET care e comandat ,am vazut ca nu primeste comanda din MainB.Ce am facut ,am dat eu dintr-o sursa externa

si ledul rosu imediat s-a aprins.Dat degeaba dau din butoane sa porneasca ca nu face sa treaca pe verde.Am tensiunile pe main de 5V si 3,3V prezente.Problema e ca nu gasesc manual nici la sursa si nici la main.Poate e din soft ,are cineva salvat macar partea de SPI?Ca nand nu prea cred.

Va multumesc.

Iti miroase a trecere de Traznarica si Fulgerica prin  zona ?

Ceva urma de "flame" prin zona hdmi sau scart ?

Daca s-au intalnit cei mai de sus amintiti cred ca ai nevoie de un alt mb digital...

Sau poate teleul a mai fost praduit de vreun meserias inaintea ta de placa logica...
