Defect sunet Philips 37KV1212/o2B

Recommended Posts

Am un batranel de philps 37KV1212/o2B de vreo 15 ani.A functioant excelent pana acum ceva timp cand incepuse sa intre pe sunet un brum atunci cand imaginea devenea mai luminoasa. Dupa ce am schimbat in electolitic ,din calea comuna cred, si-a revenit. Acum de vreo cateva zile un defect asemanator.Cand imaginea devine mai lumioasa creste volumul sunetului.Am incercat sa ii gasesc problema dar nu ii dau de cap. Ma poate ajuta cineca cu un sfat o schema?

Incercati sa reglati fin bobona demodulatorului sunet s-au incercati cu un alt TDA8305!!! Condensatorul de filtraj din pinul 7 al TDA8305 l-ati inlocuit??
