Are cineva drept de acces la sistemul EURAS (telezimex)? Acolo se descrie o posibila solutie pentru aceaste problema:


CS-907

Intermittent sound drop-outs at lower volume on various loudspeaker outputs.

Daca se poate sa se posteze si aici solutia, ar fi ideal!!!

Am schimbat arhiva, acum se descarca.

Este receiver dolby, intrare pe optic de la PC (SPDIF). Are probleme la volum de iesire mai mic, indiferent de nivelul semnalului de intrare... Daca dau volumul mai tare de oriunde, se "curata semnalul" in 2-3 secunde si dupa aceea nu mai are problem o vreme.

DUPA 2 ANI AM GASIT SOLUTIA:

- cauta 2 releuri, le scoti capacul, apoi arcul, le cureti contactele, le montezi la loc si voila

- inainte sa le desfaci, loveste-le usor, sa vezi cum isi revine sunetul pe o perioada Smile

de obicei asta este datorita unui condensator electrolitic strapuns.

amplitunerul fiind o chinezarie, nu e de mirare ca dupa cativa ani acesti condensatori se usuca (fiind ieftine si de proasta calitate).

data toate boxele fac la fel in acelasi timp, probabil sursa este de vina.

incearca sa vezi condensatori umflati etc.
