Check the usual suspects:
  • Forgotten solder joint,
  • Bad solder joint (reflow suspicious joints),
  • Reversed components (electrolytics, tatalum's, diodes, transistors, IC's). In case of IC's, probably destroyed, better replace,
  • Components in the wrong place like IC's or transistors,
  • Trim all the component leads and test pins as short as possible. Nothing must touch the chassis plate.
