MOST LIKELY YOU HAVE FAULTY CAPACITORS ON THE INVERTER BOARDS. THEY SHOULD BE 470UF 35V TYPES. THERE SHOULD BE 2 ON EACH INVERTER BOARD. If the tops of the capacitors are bulged, that's most likely your problem.
That white line (usually jagged) is actuallly part of the transmitted picture. However, you are not intended to see it because it is located in what is known as the 5% overscan area. Your TVs today are more than just cable ready... they are a versital, technology filled multimedia display. You can see that line because the screen size or wide mode you are using is intended for 1080p/24 signals. You have 0% overscan with this screen size setting. This allows you to see ALL of the picture, including portions of the picture the broadcaster did not intend for you to see. You can change your screen size using the Wide feature in the Setup menu. See pg.62 of your user manual for details and descriptions of the various wide modes.
If the backlights for the screen do come on and you also have 12v and 5v feed the main board then it does sound like the mainboard will need to be replaced.
