11AK19P4 PRO. imaginea apare dupa cateva minute


Recommended Posts

Rastrul apare greu,[peste 1 min].Cu cat televizorul sta mai mult timp stins, cu atat apare imaginea mai tarziu.Am marit G2 pana aproape de aparitia cursei inverse,dar defectul persista.Cu rastrul stins,daca ating cu multimetrul unul din catozi pentru a-i masura tensiunea,apare imaginea..Deci nu deschide circuitul video decat atunci cand apare o rezistenta intre catozi si masa.[rezistenta multimetrului].Tensiunile sunt aprox 140v la toti 3 catozii dupa aparitia imaginii, culorile normale,contrast bun,deci nu suspectez tubul.Tensiunea pe pin 5 a circ TDA 6107 [bLK in] este 5v si cand e rastrul stins, variaza putin in momentul aparitiei rastrului.
