i have the PN51D550 samsung TV and picture is black with random pixels, when i press menue i can FAINTLy see the menu through a couple pixels. i opened the back up and noticed the logic board is flashing a green light repeatedly, so i checked all power on all other boards and resistors and they seem fine, so i unplugged a couple ribbons and the green light still flashes, witch tells me its the logic board. Is this right, or does the green light always flash no matter what? usually its a diagnostic light USUALLY so im just wondering if it would be the BRAIN/Logic Board? PIC OF SCREEN IS BELOW, MINUS MY DAUGHTER LOL
