1. Turn off the TV and unplug it from the power outlet.
2. Locate the two alignment screws on the back of the TV. They are usually located near the top and bottom of the TV.
3. Using a Phillips head screwdriver, turn the alignment screws clockwise or counterclockwise until the picture is aligned properly.
4. Once the picture is aligned, tighten the alignment screws.
5. Plug the TV back in and turn it on.
If you are unable to align the picture yourself, you may need to contact a qualified technician.
