Samsung tv blows fuse.un55eh6000f

[ronl]

Hi Members.I have this flat screen in for repair hopefully. The Power supply fuse is blown.i found out that the switching transistor is shorted so far.not sure if I can get parts for the power supply but a replacement board is available.usually at this point ,i pull out the schematic(don't have) and find out if something else overloaded the power supply before I replace anything.one common cause iirc, is the backlight arrays. Anybody know what voltage is needed and the current drawn by the backlights?. Power supply # is bn44-00499a.Thanks for any help. RonL
