Yamaha DSP A1000

Recommended Posts

Va salut. La acest receiver yamaha DSP A1000 intra protectia dupa aproximativ 3 secunde de la pornire. Am gasit contacte reci si acum ramane pornit, releele se aud cum cupleaza dar selectorul de intrari este motorizat si se plimba singur de la un capat la altul, sau cateodata pana la jumatate. Chiar daca se misca singur, pe ecran nu sunt afisate si intrarile, de ex. cd, aux, tuner, etc. Cand am verificat cu atentie amplificatorul si am gasit lipituri reci am desfacut selectorul si dupa ce l-am curatat si uns l-am montat la loc. Se poate ca problema sa fie cumva de la montarea gresita in interior a contactelor sau problema sa fie altundeva. Va multumesc anticipat.

Da e selectorul e problema tipica e partea de contacte de duce la procesor probabil (cazul tau).

Practic nu stie in ce pozitie e .

La mine facea probleme pe partea de audio a selectorului (ramanea pe pozitie dar contact prost pe audio)....si cateodata ca la tine.

Am curatat selectorul .

Am facut o placa cu 9 relee care se potrivea exact pe mufele de erau pe selector .

Partea de audio practic am trecut-o prin relee.

Releele erau actionate de selector (in selector practic am scos toata partea audio si am dus un 5v deci selectam un 5v cu care dateam in relee)

Cand selectionai practic actionai releul .......ca sa fiu sigur am pus in paralel contactele ca selectorul e stereo .

Pare complicat dar e simplu o sa-ti trimit fisierul daca-l gasesc .

O sa caut poza
