Solutions and Explanations
• Set your PC's output resolution so it matches the resolutions supported by the TV. (p. 12)
• This is normal; "PC" is always shown on the source list, regardless of whether a PC is connected.
• If you are using an HDMI connection, check the audio output setting on your PC.
• The Samsung Wireless USB dongle is required to use a wireless network.
• Make sure the Network Connection is set to Wireless (p. 31).
• Make sure the TV is connected to a wireless IP sharer (router).
• Try network test in Setup menu (p. 26).
• If you have latest SW version, SW upgrade will not proceed.
• Remove the left and right audio connections from the set-top-box. If the buzzing stops, this indicates
that the set-top-box has a grounding issue. Replace the Component video cables with an HDMI
connection.
• HD channels will have black bars on either side of the screen when displaying up scaled SD (4:3)
contents.
• Black bars on the top and bottom will appear during movies that have aspect ratios different from
your TV.
• Adjust the picture size options on your external device or TV to full screen.
• Replace the remote control batteries with correct the poles (+/–) in the right direction.
• Clean the sensor's transmission window on 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/Sat remote control to operate the TV. Refer to the Cable/Set user manual for the
SAMSUNG TV code.
• Check the supported resolution of the TV, and adjust the external device's output resolution
accordingly. Refer to the resolution settings on page 12 of this manual.
• Caption can not be selected in the TV menu when connected via HDMI or Component (p. 26).
• Caption must be activated on the external device (p. 26).
• This smell is normal and will dissipate over time.
• This function is only available with digital channels from an Antenna / RF/Coax connection. (p. 28)
• Remove the base stand from the TV and reassemble it.
• The Channel menu is only available when the TV source is selected.
