Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, let's start and review the basics. Proposed preliminary tries (if have not been done):

  • determine the part number of the power supply board, something like a DPS-408AP B;
  • test for the presence of the +12V and the +5V among others;
  • the voltages would normally be printed/stenciled on the pins/terminals of the connectors;
  • visually inspect for any leaky capacitors;
  • if the +5 and +12 are present but the TV still show completely/electrically dead, then suspect/replace the main board;
  • likewise determine the main board number, something like a SC0-P710201G000.
