Am un tv Sharp de reparat . A avut verticalul defect, se vedea o linie orizontala. Am gasit tranzistorii finali IRf 9020, 020 defecti si i-am inlocuit. Am mai gasit o dioda zenner in scurt. Acum verticalul se dessoara cam 3 sferturdin ecran dar nu am rastru. Imi apare imagine de AV si cursa inversa. Va rog daca ati mai intalnit acest defect sa ma ajutati. Multumesc.
