                O mica mare precizare:

       -SAA5264=teletext si nu procesor,

       -8801cpcng4n98 este UOC, adica si procesor si jungla(multifunctional daca doriti).

   Trebuie urmarit traseul de la SCART(pinii 2 si/sau 6),sau mufele RCA,alba sau rosie(dupa gust si preferinte).

  Este bun un osciloscop(si un generator de semnal),dar in lipsa porniti tv ,conectati in A/V o sursa de semnal si urmariti auditia intr-o casca telefonica(de tipul celor folosite in vechile aparate EM-72),si vedeti unde dispare.Nu strica sa incercati si alt dump.
