ia vezi in functia av ,face la fel ?? Parerea mea e , ca e cursa de stingere ....cadre sau hs . Tin minte ca ,am avut un defect asemanator la un alt model de tv . Iti recomand sa inlocuiesti la pin 3 r 8k2 , c-ul de 100pf si dz 9v1 dar si ferificarea diodei d107 (scurcircuitata sau cu rez mica ) cat si alimentarea cu 8v prin rez-le de 10k 152+153 . totodata schimba ci c-ul 2u2 de la semireg. de liniaritate sau chear pe el . Vezi si rez 624 ...!? Astept raspuns .SM!
