    alternative diode to Samsung TV 55 mb

    Hi, Recently my Samsung 4K QE55Q60AAUXXH just suddenly stopped working_ there is no any sign of life - no red light or anything..and think, after diagnostic, it is diode DM863c SF28e PK33 siyu or one of these four. Is there any alternative I can replace with since it is hard to find it in my country and to order outside is quite difficult. thank you...

    It's probably similar to UF4007

      SF28 is 2A, and UF4007 is 1A - which means it won't work.

      Try to find HER207 and exchange all 4 pieces for it.

        i saw that 500v caps... but it's not that high.. it stays probably for Super Fast 2A 800v

        check THIS https://www.alldatasheet.net/categor...T%20DIODE%202A

        (equivalents)
