Please check the flat cable connections between TCON board and the LCD panel. If this is ok, then it is either the TCON board or the LCD panel itself. Good luck.

Check and replace the backlight inverter board. Do not think that it works only with some capacitors. The inverter transformers are the main component on that board, and always gets shorted inside, and is irrepariable.
