Difuzoarele le-ati verificat? Lipituri la TDA7056 ati refacut? Verificati QV18, eventual strapatii jonctiunea BE sau scoateti-l din circuit urmarind daca defectul persista; verificati semnalul A.MUTE.viewtopic.php?f=17&t=12666

Verificati la pinul 3 TDA7263 daca "lucreaza" semnalul MUTE: daca aveti sub 1,6Vcc finalul este blocat; daca aveti peste 4,5Vcc finalul amplifica, in acest caz defectul poate fi la comutatorul AV sau la jungle (lipituri reci).
