However when I disconnect the cable from the power board to the T-con board, the red light comes on the front (just like it should) and the screen lights up when I push the power button. Then, when I connect the t-Con cable, the TV works perfectly. When I unplug the power cord and plug it back in, I'm back to where it started showing no signs of life. Do you think I need to replace the power board or the T-con board(or any parts you would recommend replacing)?
