    Samsung PS50A410 - big bang and no idea!

    Hi,

    I need you help to repair a Samsung PS50A410.
    The Power Supply (DYP-50W3) has only Stand-by power.

    I have changes the Caps (CP805 and CP806), the bridge rectifier (BP802) and checked all diodes.
    In Stand-by-mode no reaction. After I had turned on the Power
    I had a small bang and short-cut between all pins from QP801 (19N60).
    I can't find the reason for the short-cut...

    Here is the shematic:

    Has anyone an idea for the troubleshooting?

    Sorry for my bad english, maybe it will be better when I write here in this forum ;D

      Clear pictures are important, can you post some? Could have been the fuse that popped too

          There are some pictures.
          The fuses are okay, the varistor has 0 ohm and will be replaced when I had found the defect part(s).
