Symptom Cause and Possible Remedy Reference
Section
There are spots on the
picture, or the screen
shakes Is the system affected (by radio wave interference or induced
electromagnetic waves) by external sources (automobiles or trains,
high-voltage wires, neon, motors, magnetized steel frame, or iron rain
shutters, etc.)?
►Turn off the power supply, and try changing the equipment setup
location. If that has no effect, separate magnet-proofi ng will be
required.
-
The image appears
doubled or tripled Is the antenna direction shifted?
Are refl ected electromagnetic waves being received from mountains
or buildings?
-
A color pattern appears,
or colors disappear Is the equipment being affected by another TV (electromagnetic
interference)?
►Changing the TV setup location may lead to improvement.
-
The channel number
disappears from the
screen Has the RECALL button been pressed?
►Press the “RECALL button” again.
If the system is switched to external input and there is no external
signal video, the number will disappear.
Basic Controls
When the image is not
stable, the screen turns
completely white for a
moment
This occurs when the signal driving the liquid crystal is lost, and is not
a malfunction.
-
The screen goes dark
momentarily when the
channel is changed.
The screen is darkened for a moment to conceal noise generated
when changing channels.
-
The TV makes a hissing
noise occasionally If the screen and audio are not abnormal, this sound is caused by
slight expansion and contraction of the cabinet due to changes in
room temperature. It has no effect on performance.
-
The screen display shakes
with video input When input is switched to “video input”, this may occur if there is no
signal at the video/audio input terminal. How to Connect the
Input Terminals
A black band appears
momentarily when
selecting channels with
video
This is due to noise generated when changing channels. -
Both edges of the screen,
or columns or window
frames, appear bent
They may appear bent due to the received channel or some DVD
software. This is not a malfunction.
-
The image from the
connected equipment
does not appear Are plugs securely inserted into each terminal?
►Securely insert plugs all the way.
How to Connect the
Input Terminals
The main unit is hot to the
touch The main unit radiates heat, so some parts of the console reach a
high temperature. This is not a problem for performance or quality.
Set up at a location with good ventilation. Do not cover the ventilation
holes of the console with a tablecloth, etc., and do not place on top of
other equipment (like a video deck).
