Probleme Sony CFD-S20CP


Recommended Posts



Am desfacut casetofonul sa ma joc un pic prin el, achizitionand de curand un analizor logic. Problema e ca nu stiu ce a patit, dar cand conectez cablul de la placa CD (pag. 24) la main board se stinge LCD-ul si nici nu functioneaza nimic de la CD. Radioul merge normal cu placa CD conectata.

Am banuit un scurt la inceput, mai ales ca daca bag cablul flex oblic (primele contacte 1,2 sa nu faca contact), LCD-ul ramane aprins si se stinge doar cand bag cablul flex complet. Am alimentat si placa separat si am masurat cat curent intra in ea. Pe linia de 6.2V trage ~4mA si pe cea de 3.3V cam 80mA. Vi se pare mult?

Daca m-ati putea ajuta cu un sfat sau de unde sa incep, as aprecia enorm. Nu am deloc experienta in depanare :)




PS. Nu am putut sa atasez manualul de service. Il puteti gasi aici: http://diagramas.diagramasde.com/audio/CFD-S20CP%20sm.pdf
