Acelasi model tv am si eu si acelasi defect. La indemnul unor colegi forumisti, l-am deschis si i-am refacut toate lipiturile care mi se pareau a fi in neregula sau prezentau urme de oxidare (cele mai multe se gaseau in zona transformatorului de inalta tensiune). Am beneficiat si de ajutorul unei lupe mai puternice pentru a vedea asa zisele lipituri reci. Nu am reusit sa identific o astfel de lipitura, dar la terminarea operatiei de refacere a acestora am constatat ca tv functioneaza perfect. Bafta!
