Problem
An OSD instructing to replace the lamp is
displayed. (The LAMP indicator is lit red.)
Relighting the lamp when it is hot makes a
sound.
Leaving stationary images, such as still
video images, web pages, or filler bars (used
for NORMAL aspect mode), on-screen for
an extended period of time can leave ghost
images on the screen.
An OSD advising "AIR FILTER
CLEANING..." is displayed.
When viewing with HDMI connection, picture
is displayed with unnatural colours (as if red
and blue are reversed).
Pictures from equipment are unusual when
the equipment is connected via HDMI.
No sound is produced.
Possible Solution
• Replace lamp with a new one.
• This is a characteristic of the lamp and not a malfunction.
• This is a characteristic of the LCD panel and not a malfunction. Try
displaying constantly moving pictures which fill the entire screen, or
turn the power OFF for a while to return the screen to normal.
• Please consult your nearest dealer.
• Change "Color corr." from "Off" to "On".
• Is the HDMI cable connected properly?
• Turn Off the TV unit and device, then turn them On again.
• Check the input signal from the equipment.
• Is "Sound Mute" active?
• Is the volume set to the minimum?
• Is "Speakers" set to "Off"?
• Change "SAP" settings.
• Check "HDMI1 in" or "HDMI2 in" insettings when the equipment is
connected via HDMI.
• If digital sound connection has problem, select analog sound
connection.
