Buna ziua , acest televizor lcd prezinta zone puricoase in zone mai luminoase ale imaginii si in jur de 10 linii puricoase verticale pulsatorii situate la distante egale peste imagine , pe imagini intunecate liniile verticale se accentueaza si zonele dispar iar pe imaginile luminoase liniile se atenueaza si zonele sint mai vizibile . Am gasit in secundarul sursei si pe mainboard electrolitici devalorizati dar dupa inlocuire nici o schimbare . Ce parere aveti de acest defect ? e de la t-con ? ( nu are AS15 ) sau de la mainboard ? Multumesc .
