popa ionut Posted October 27, 2012 Share Posted October 27, 2012 Am inteles,va recomand schimbarea tuturor tranzistorilor sunt de proasta calitate cei din schema si a diodelor...am atasat o schema ceea ce difera or sa fie tipul tranzistorilor si notatiile in rest este aceeasi sursa de SANYO copiata si simplificata..de chinezi http://www.hotfiles.ro/download/tv_2.rar/705198 Quote Link to comment Share on other sites More sharing options...
dan cod Posted October 27, 2012 Share Posted October 27, 2012 Singurul cu probleme in sursele astea este A1015 dar in cazul asta este pus din fabrica altceva deci e ok.De fapt poate ca nici nu are defect de sursa.Nu a spus ce face tvul.

dumitru_a Posted November 28, 2012 Share Posted November 28, 2012 Va rog o schema pentru acest sasiu daca se poate si cum se poate intra in service meniu (cred ca este o tasta ascunsa), am un televizor care nu mai prinde posturi pe banda b1 , am presupus ca selectorul et-5ee-k04 este defect , se poate inlocui acest selector cu uv1316/a ?
