Possible Solution
• Black bars on each side will be shown on HD channels when displaying upscaled SD
(4:3) contents.
• Black bars on Top & Bottom will be shown on movies that have aspect ratios different
from your TV.
• Adjust picture size option on your external device or TV to full screen.
• Replace the remote control batteries with correct polarity (+ -).
• Clean the transmission window located on the top of the remote.
• Try pointing the remote directly at the TV from 5~6 feet away.
• Plasma TVs typically make a soft humming sound. This is normal. It's caused by the
electrical charges that are used to create the images on the screen.
• If the humming sound is loud, you may have set the brightness on the TV too high.
Try setting the brightness lower.
• You can also have loud humming if the back of your Plasma TV is too close to a wall
or other hard surface. Also try rerouting your connection cables.
• Improper installation of wall mount can create excessive noise.
• To minimize the possibility of screen burn, this unit is equipped with screen burn
reduction technology. Pixel Shift technology enables you to set picture movement up/
down (Vertical Line) and side to side (Horizontal Dot).
• Program the Cable/Set top box remote control to operate the TV.
Refer to Cable/Set top box user manual for SAMSUNG TV code.
• Check the supported resolution of the TV and adjust the external device's output
resolution accordingly. Refer to resolution settings in this manual.
• This smell is normal and will dissipate over time.
• This function is only available with digital channels with an Antenna (RF/Coax)
connection.
• Remove the stand base from TV and reassemble.
• Make sure TV is placed on flat surface.
If can not remove screws from TV, please use magnetized screw driver.
