Nu trebuie nici o schema; trebuie montat un convertor bistandard (30 mii lei) pe modulul de sunet. Sunt trei conexiuni:1- +12V; 2- MASA; 3 - Intrare modul sunet TV. Tensiunea 12V poate fi si mai mica. DACA NU FUNCTIONEAZA DIN PRIMA, trebuie schimbate intre ele filtrele 5.5 cu 6.5 MHz de pe convertor ( de obicei cnvertoarele sunt facute din 5.5Mhz in 6.5Mhz dar sunt reversibile prin scimbare filtre)
