Solutions and Explanations
• Make sure the AC power cord is securely plugged into the wall outlet and the
TV.
• Make sure the wall outlet is working.
• Try pressing the button on the TV to make sure the problem is not
POWER
the remote control. If the TV turns on, refer to 'Remote control does not work'
below.
• Ensure the Sleep Timer is set to Off in the System menu.
• If your PC is connected to the TV, check your PC's power settings.
• Make sure the AC power cord is plugged in securely to the wall outlet and the
TV.
• When you are watching TV programs from an antenna, the TV will turn off after
10 - 15 minutes if there is no signal.
• Check the cable connections. (Remove and reconnect all cables connected to
the TV and external devices).
• Set your external device's (Cable/Sat Box, DVD, Blu-ray etc) video outputs to
match the connections to the TV input. For example, if an external device's
output is HDMI, it should be connected to an HDMI input on the TV.
• Make sure your connected devices are powered on.
• Be sure to select the TV's correct source by pressing the
remote control.
• Reboot the connected device by disconnecting and then reconnecting the
device's power cable.
• Make sure the coaxial cable is connected securely.
• Run Auto Program to add available channels to the channel list. There are 3
options, STD, HRC and IRC. Most cable systems use STD.
• Verify the antenna is positioned correctly.
• Check the Caption Setup menu. Try changing Caption Mode Service1 to CC1.
• Some channels may not have caption data.
• The compression of video contents may cause picture distortion, especially in
programs with fast moving pictures such as sports programs and action movies.
• A weak signal can cause picture distortion. This is not a TV problem.
• 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.
• 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 the wall mount can create excessive noise.
