Warnings and Cautions
High voltages are used in the operation of this product.
Do not romove the cabinet back from your set. Refer
servicing to qualified service personnel.
To prevent fire or electrical shock hazard, Do not expose
the main unit to rain or moisture.
Do not drop or push objects into the television cabinet

slots or openings. Never spill any kind of liquid on the
television receiver.
!
Caution
If the television is to be built into a
compartment or similarly enclosed, the
minimum distances must be maintained.
Heat build-up can reduce the service life of
your television, and can also be dangerous.
Page 8
!
Caution
Never stand on, lean on, push suddenly the product or its
stand. You should pay special attention to children to children.
!
Caution
Do not place the main unit on an unstable cart stand, shelf or
table. Serious injury to an individual, and damage to the
television, may result if it should fall.
!
When the product is not used for an extended period of time, it
Caution
is advisable to disconnect the AC power cord from the AC
outlet.
!
Avoid exposing the main unit to direct sunlight and other
source of the heat. Do not stand the television receiver
directly on other produces which give off heat. E. g. video
cassette players,Audio amplifiers. Do not block the
ventilation holes in the back cover. Ventilation is essential to
prevent failure of electrical component. Do not squash power
supply cord under the main unit.
!
Caution
Caution
The LCD panel used in this product is made of glass.
Therefore, it can break when the prod uct is dropped or
applied with impact. Be careful not to be injured by
broken glass pieces in case the LCD panel breaks.

REPLACEMENT OF MEMORY IC
1. MEMORY IC
This LCD TV uses memory IC. In the memory IC are memorized data for correctly operating the video and
sound circuits. When replacing memory IC, be sure to use IC written with the initial value of data.
2.CHECK MEMORY IC
(1) Power off
Unplug the ~120V power plug from ~120V power socket.
(2) Replace IC
Be sure to use memory IC written with the initial data values or blank memory IC.
(3) Power On
Plug the ~120V power plug into ~120V power socket. (If memory IC is blank, the program will take 25s to
initial memory IC.
(4) Check and set SYSTEM default value:
1) Press “DISPLAY” key, then press colour key “red”,”green”,yellow”,”DISPLAY” on the Remote control
unit continuously for factory used.
2) The “Factory2” will be displayed on the screen,
3) Check the setting value of the SYSTEM default value of Table below. If the vale is different, select
items by [CH-]&[CH+] keys and set value by [VOL-]&[VOL+] keys.
4) Press “OK” key and return to the normal screen.

3 SVRR SVRR is the midrail bypass mode enable
4 OUT1 OUT1 is the audio output for channel 1
5 PGND PGND is the power ground refernce
6 OUT2 OUT2 is the audio output for channel 2
7 VCC VCC is the supply voltage input.
8 M/SB M/SB is the mute/standby mode enable. When held at less
than 2V, this signal enables the TPA1517 for standby
operation. When held between 3.4V and 8.8V, this signal
enables the TPA1517 for mute operation. When held above
9.2V, the TPA1517 operates normally.
