Platinium CTV 21 S1 Defect sunet


Recommended Posts

Sanatate !! Sasiul este : ETE-3 .. Sunetul scade pana aproape la 0 apoi isi revine , asa face tot timpul cam din 10 in 10 secunde ... sunetul nu este distorsionat ... am verificat alimentarea circuitului de sunet . am schimbat electroliticii , dar fara rezultat !!

Nu !! Am urmarit si eu sa vad daca atunci cand scade sunetul apare OSD-ul , dar nu apare .. si  atunci  in acele cateva secunde cand este cu sunet scazut  daca  apav pe vol+ bara de sunet este la valoarea care  era ..

Am inlocuit :v601,v621.vd621,vd622 ... se pare ca functioneaza  acum .. o sal urmaresc sa vad daca mai face , dar de 10 min nu a mai scazut sunetul ... Masurate aceste componente sunt ok .. diodele nu au rezistenta interna .. Nu stiu care era defectul dar sa remediat !!
