cristiandan Posted July 17, 2007 Share Posted July 17, 2007 La acest sasiu de Sony(model Kv-21T1K),in mod AV imaginea e impecabila dar sunetul lipseste cu desavarsire.Am verificat si schimbat tranzistoarele din comutator Q100,105,114,diodele in comutatie Q100,Q114 dar defectul persista.Tv-ul functioneaza normal in mod TV si comuta TV-AV si invers.Poate fi defect proc.SAA5291?Multumesc !
