JAD Posted July 14, 2009 Share Posted July 14, 2009 Deconecteaza etajul de baleiaj orizontal (dezlipeste C de la Tz final linii) si scoate din placa tiristorul din sursa. In acest fel sursa debiteaza tensiuni normale (de power-on) si o poti verifica cupland un bec de 230V/60-100W pe bara de alimentare a baleiajului orizontal. Tensiunea corecta este cam 112V-115V pentru tub normal si cam 124-128V pentru tub perfect plat.Dupa reparatia sursei si eliminarea componentelor in scurt poti pune la loc tiristorul din sursa si verifica restul.Tine-ne la curent cu stadiul reparatiei.
