    Hi to all in searching for help i found your forum . My proplem is a burnout le32d400e1w samsung tv and the proplem is at the Samsung BN44-00438A Power Supply Unit . Two parts are burnout the first is a 5n52u transistor and the second is 474J400V capasitor ( the ather letters on the capasitor are S B26 MPP). I include 2 pictures can anyone please help me . The technician says to me that he cant find any diagram to put the correct parts.
    The ather numbers on the unit are .BN44-00438A , 12632F1_BSM , SEC S/N:CN088N4400438ASE38B7QN998 RD , PB7L009134 . I am living in greece and my economy is very low to buy the new part (150-200euros ). Any help would be good . Thank you all for reading me .

    Without a schematic, and the skill to diagnose the power board, you might consider replacing the entire board. You can find them on e-bay, for instance.

    Unless the transistor is a "house coded" part, the number you've given doesn't make any sense - perhaps starting with 2N, but I'd expect 4 digits after the N.

    For the capacitor; 474 is the first 2 digits of the value and the multiplier in pF, so that's 470,000pF or 470nF or 0.47uF. If you figure the rest out - don't skimp on the capacitor voltage!
