Is it still under warranty? If not I would find a good TV Service Shop and have them check out the power supply as there more than likely a 'Capacitor' much like a battery that is going bad. Blessings, A/V Media Guy
Check capicitor in vertical hold circuit. You should have solid knowledge of electronics repair before attemping repair. TV's can emmit harmful radiation, and produce voltages up to or in excess of 30kV.
Hi I had the same problem. Broken white lines across the top of the screen. This is called overscan. You need to go into the Setup menu, other settings. 16:9 overscan needs to be on. Hope this helps.It solved our problem.
