A bit hard to say definitively. At the bottom of the TV (inside) you'll see a smallish board (T-Con) with flat leads (Flexy cables, usually 2flexy) going to the long boards along the bottom of the panel. I'd start by disconnecting one flexy at a time, switch the tv on and see if you get a clean half of the screen (may be pure white, black or have vertical lines). Then reconnect that flexy and unclip the other one and check the screen. Report back with your results (pictures are good) and we'll go from there. Bruce
