Check the controller board, 6871QCH038A. This board is one layer deep into the assembly after the cover is removed. Gently lift the covering circuit board back plane to access.
To do this direct a blast of cold air unto the large chip in the center of the board. If the picture comes back on then you have found it. This means powering the TV while open and this means danger to the novice. Voltage can end your life when you become the circuit path.
Order Part number 6871QCH060Q as the suitable replacement part to this circuit board.

Most a likely a problem with your Y-Sustain board which will then not drive the screen giving a black picture. The fuse on the board may be open circuit & need replaced but most likely you will need to have the sustain board replaced.
