Solutions and Explanations
• 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).
• This smell is normal and will dissipate over time.
• This function is only available with digital channels from an Antenna / RF/Coax connection. (p. 22)
• Remove the base stand from the TV and reassemble it.
• The Channel menu is only available when the TV source is selected.
• If the TV is in the Store Demo mode, it will reset audio and picture settings every 30 minutes. Change
the settings from Store Demo mode to Home Use mode in the Plug & Play (Initial setup) procedure.
Press the SOURCE button to select TV mode, and go to
setup) → ENTERE (p. 7).
• Check the cable connections and reconnect them.
• Loss of audio or video can be caused by using overly rigid or thick cables. Make sure the cables are
flexible enough for long term use. If mounting the TV to the wall, we recommend using cables with 90
degree connectors.
• This is part of the product's design and is not a defect.
• PIP functionality is only available when you are using a HDMI, PC or components source (p. 21).
• If you are using a CAM CARD (CI/CI+), check that it is installed into the common interface slot.
• If there is still a problem, pull the CAM CARD out of the TV and insert it into the slot again.
• It is normal. The TV operates the OTA (Over The Aerial) function itself to upgrade firmware
downloaded whilst your watching TV.
• Check and change the signal/source.
• To prevent this, use felt pads on any surface of the TV that comes in direct contact with furniture.
