Buna dimineata.La acest sasiu am schimbat tunerul si in urma acestei schimbari am imagine clara dar nu am sunet.Tunerul este identic THOMSON.Tensiunile sunt bune pe tuner.Am un fasait ca atunci cand nu este pe norma de sunet.Am schimbat  ci sunet si c-urile electrolitice din etajul de sunet dar nimic.Tensiunile sant bune,schimbat si filtru si nimic.Ce ar mai fi?multumesc.

Tunerul a fost rupta mufa de intrare si nu se mai putea repara.Am incarcat o memorie noua 24c08 cu dumpul de la d-l FLORIN si apornit cauta programe schimba normele de sunet dar tot nu are sunet.

      Of,of,of........tv vine cu mufa rupta la selectror,care a fost inlocuit=acesta era defectul tv-ului.Acum am ajuns la memorii  :rade: .Aici sunt 2 situatii:

1-tv nu a avut sonor,si clientul "mananca bors",

2-in timpul manevrei de inlocuire a selectorului,a zburat pe undeva o mustata de cositor,sau UOC a fost avariat partial ,datorita unei sarcini electrostatice.
