Am un tv samsung format 16:9 cu diagonala 82cm. In partea stanga a imaginii sesizez niste bare verticale ca un fel de cortina mai ales atunci cand in camera este intuneric iar fondul este uniform colorat. care ar putea fi problema?multumesc

finalul video are catozii alimentati cu 180V de exemplu, tensiune culeasa de pe un secundar de la trafo linii. electroliticul de pe bara asta de tensiune schimba-l. vezi daca nu e eventual pe linga un radiator sau rezistenta de putere care se incalzeste si il usuca
