Solutions and Explanations

• Try pressing the POWER button on the TV to make sure the problem is not the remote. If the TV turns
on, refer to "Remote control does not work" below.
• Ensure the Sleep Timer is set to Off in the Setup menu (p. 16).

• Make sure the AC power cord is plugged in securely to the wall outlet and the TV.
• When watching TV from an antenna or cable connection, the TV will turn off after 10 - 15 minutes if
there is no signal.
• Check 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.

• If you are using an HDMI connection, check the audio output setting on your PC.
• 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.
• Replace the remote control batteries with 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.
