Problem
Vertical bars appear to
flicker, jitter or shimmer
on the image.
Screen is black and
power indicator light
blinks steadily.
Image is not stable and
may appear to vibrate
when you have a
computer connected to
the PC input.
Image is not centered on
the screen.
If a still image is displayed
for an extended period of
time, residual images or
blurring may appear.
The TFT LCD panel uses a panel consisting of sub pixels [2,764,800 (LN-R237W1 - 3,147,264)] which require
sophisticated technology to produce.
However, there may be few bright or dark pixels on the screen. These pixels will have no impact on the
performance of the product.
Possible Solution
Adjust the Coarse tuning and then adjust the Fine tuning.
On your computer check: Power, Signal Cable.
The TV is using its power management system.
Move the computer's mouse or press any key on the keyboard.
If the setting is not correct, use your computer utility program to
change the display settings.
NOTE: Your TV supports multiscan display functions within the
following frequency domain:
Horizontal frequency
(kHz)
Vertical frequency (Hz)
Maximum refresh rate
(at 60Hz)
Adjust the horizontal and vertical position.
The screen position must be adjusted on the output
source (i.e. STB) with a digital signal.
When you need to leave the monitor unused for an extended
period of time, adjust the settings so that the monitor
automatically goes into energy saving mode or activates the
screen saver to display moving images.
