I was working on a 55lf6000-UD television, i had just replaced the LED strips(Flashing issue) but when I got it back together, the screen had lines and was going all white. (As far as I’m aware, I didn’t crack the screen) I was bending over the tv, with a hoodie on, and , (drumroll please) my metal hoodie sting aglets shorted the power supply. so i ordered a new one. Now, i have the tv on, was expecting the white screen which i was hoping the OK & EXIT trick would work on, but instead the backlights are on, but the screen is completly off, barely some light bleeds from the corners. Im lost on this, all my ribbon cables are snug. what could my problem be? Main Board fried during the shortage? TCon gone bad?
@nham919 if you have no video is is most commonly the main board. After all, all video processing is being done on that board.
