PROBLEME FOCALIZARE


Recommended Posts

Va salut cu respet, este vb.de un tv EDELSTEIN cu procesor TDA 11106PS,cadre UT 78040, memorie FM 24C08A,sunet TDA 1030,si sursa cu tranzistoare.La pornire este defocalizat complect, luminozitate redusa (la rece)si cum se incalzeste incepe sa se focalizeze imaginea si se lumineaza normal. Am curatat soclul TK si parca revine mai repede dar tot se manifesta.(inainte necesita 1 ora sa revina ,acum doar 10 min.)Vreau doar un sfat ca nu mai stiu ce sa-i fac ,poate sa faca asta si tubul cinescopic? daca cineva stie si eventual cum se intra in service menu ar fi bine. Va multumesc mult ,toate cele bune!
