Problem
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.
The picture appears distorted in the
corner of the screen.
The 'Resets all settings to the default
values.' message appears.
This TFT LCD panel uses a panel consisting of sub pixels (6 220 800) 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
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.
Your TV supports multiscan display functions within the following
➣
frequency domain:
Horizontal frequency (kHz)
Vertical frequency (Hz)
PC Maximum refresh rate (at 60 Hz)
Adjust the horizontal and vertical position.
The screen position must be adjusted on the output source (i.e. STB) with a
digital signal.
If "Just Scan" is selected with some external devices, the picture may appear
distorted in the corner of the screen. This symptom is caused by the external
devices, not TV.
This appears when you press and hold the EXIT button for a while. The product
settings are reset to the factory defaults.
