• There could be interference from another electrical appliance, such as a computer,
another TV or VCR. Move any such appliances further away from the TV.
• There could be interference from a high-wattage appliance, like a hairdryer or vacuum,
operating nearby. Move the antenna away from the appliance or change to a coaxial
cable connection which is less prone to interference.

slightly delayed one. Adjust your antenna position.

connection. If the antenna is damaged, replace it.

electrical plug from the wall outlet and wait a while before inserting it into the wall outlet
again and operating the television.
The POWER LED

LED are blinking
alternately.
• It may be a malfunction that the fan is locked or the temperature has increased.
The POWER LED
and LAMP/PROGRAM
LED are blinking
rapidly simultaneously.
• The lamp may not have been installed correctly, or it may be due to a malfunction.
• The lamp door may not be closed correctly.
The LAMP/PROGRAM

• It may be a malfunction of the internal electrical circuits.
• The antenna could be disconnected.
• The input mode could be set improperly. See page 68.
• The tuner (Auto Tuner Setup) could be set improperly. See page 37.
• The TV station may be having difficulties. Check to see if other stations are working.
• Use the HDMI cable with HDMI logo . See page 22.
• You can not output audio using the AUDIO OUTPUT under the following conditions:
1) When you have digital sound from an HDMI device connected to the HDMI 1 or
HDMI 2 connection on the back of your TV. (See page 22).
2) When you have analog sound from a DVI device connected to the
AUDIO IN "HDMI 1" connection. (See page 21).
• When you have an HDMI device connected to the HDMI 1 connection on the back of your
TV, your TV detects it, and blocks the analog audio signal coming into the "HDMI 1”
jacks. Therefore, you can not hear any analog sound from the other device conected to the
"HDMI 1" jacks, while you are viewing the images from the HDMI device.
