Problem
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.
You may see small particles if you
look closely at the edge of the bezel
surrounding the TV screen.
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
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.
This is part of the product's design and is not a defect.
