Sziasztok!
16:9-es 66cm-es CRT TV bekapcsolva klattyog a relé, a B+ 145V-rol leesik 130V-ra, a BU melegszik, tehát le van terheve.40W Égôvel stabilan áll a 145V.
Ha kihuzom a Horizontalis elterito tekercset akkor beindul a TV nem melegszik semmi csak akkor fuggoleges vonal van. Ha lecsatolom az E/W tranzisztorra vezeto jelet akkor kb 3cm széles a kép majd 10-15sec alatt ugy felmelegszik a BU250AF hogy kiég. Leszedtem már az eltérito tekercset, de az vizualisan szépen néz ki, de 0ohm-ot mérek (egyszeru multiméterrel).
Amiket már probara csereltem:BU2508AF, meghajtoja BS270, 8.2nF/2kV meg a melette levo nagymeretu kondik, E/W tranzisztor BDW53B, környékbeli elkók, sajnos már vettem uj nagyfesztrafót is.Megmértem egy masik TV elteritojét ott is 0 ohmot mértem ebbôl gondolom az elterito tekercsem is jó.
Most megallt a tudomany..
