Problema YAMAHA RX-750

Recommended Posts

Amplificatorul sus mentionat are intrari LD/TV, VCR/TAPE 2, TAPE 1 /DAT, TUNER, CD, PHONO. In situatia actuala este blocat pe radio. La rotirea butonul pentru selectarea altei intrari (este cu clic) nu se intampla nimic, nu afiseaza ca ar comuta pe alta intrare. Ce ma nedumireste este ca are cuplat si un motoras care roteste axul selectorului, rotire fara clic(l-am alimentat separat dintr-o sursa de curent continu si roteste axul selectorului). La ce foloseste acel motoras (banuiesc ca lucreaza in impulsuri)?. De unde "sa-l apuc" sa pot face selectarea altei surse de semnal?.

Dupa mai multe sapaturi cred ca am lamurit....nelamurirea. Mototasul (pas cu pas) are rolul de a comuta intrarile din telecomanda (pe care oricum nu o are). Am crezut ca asta se face electronic. Chestia cu afisajul care ramane pe radio indiferent de ce intrare selectez este ca asa a fost construit din fabrica. Nu are pe el pixeli care sa arate ca este pe cd, phono sau alta intrare.
