Casetofon deck JVC TD-X203G


Recommended Posts

Va salut,

Casetofonul reda, dar nu inregistreaza ci doar sterge banda. Nici vu-metrul nu indica nivelul semnalului la inregistrare. Undeva, pe traseu, semnalul se opreste.

Am nevoie de o schema pentru a urmari semnalul de intrare.

Manualele de service gasite de mine pe net sunt pe bani si depasesc valoarea acestui obiect desuet. Schemele unor aparate similare nu se potrivesc nicicum.

Va multumesc.

Rezolvat. Nu era nimic defect.Inspirandu-ma din schemele altor deck-uri am vazut ca semnalul de intrare ajunge direct la potentiometrul de nivel al inregistrarii. Pe pinii potentiometrului nefiind semnal, am luat-o spre intrare.Mufele "line-in" de la deck sunt murdare/corodate in interior (cine stie cand au fost folosite ultima oara) si contactul nu este bun.

 

Am curatat RCA-urile in interior cu o scobitoare pe care am pus niste vata imbibata in alcool izopropilic.
