Samsung LN - Recent Questions, Troubleshooting & Support
Try a hard restart, which simply means unplugging the power cord of the TV, and replugging it after 4 hours have passed. This technique reprograms the electronics, to a certain extent.

Samsung ln46b630 started with verticle lines
screen ribbon needs resetting not an easy job to do if you not done them before as you need to take the screen out and remove the screen shield off to get to the ribbon, then put a foam or rubber spacer over the ribbon so that when you fit the shield case back on it just pushes on it slightly so it has good contact. and its best to do all the ribbons as this will help it not do the same to the reset.
