Receiver Pioneer cu zgomot de fond

Recommended Posts

Guest Cristi NC

Am un receiver Pioneer vsx-d810s care mergea perfect in urma cu un an dar in timp a inceput sa prinda un zgomot de fond ciudat. Mai exact acest zgomot este un tiuiit constant "puricos" care se amplifica odata cu volumul si este prezent pe toate sursele analogice optice si pe coaxial. Pe zi ce trece parca e mai puternic si mai constant si probabil la un moment dat v-a ceda ceva prin el dar nu stiu ce. La o examinare vizuala pare totul ok.

Mentionez ca am decuplat tot de la el, am schimbat prize etc.

 

Ma puteti ajuta cu vreo idee ?

În primul rând verificati tensiunile din sursa secundară apoi verificați condensatori electrolitici.

Acum la pornire nu merge un canal stereo vreo 1 minut apoi isi revine. Cred ca ii vine vremea sa-l desfac poate observ ceva vizual ca altfel nu am prea multe cunostine de electronica.

Si-a revenit statia foarte bine. Problema a fost sau mai este la potentiomentru de volum. Dupa ce l-am rotit de mai multe ori in ambele  directii statia si-a revenit miraculos.
