1. PRECAUTIONS AND NOTICES
1. PRECAUTION AND NOTICES
SAFETY PRECAUTIONS
This monitor is manufactured and tested on a ground principle that a user’s safety comes
first. However, improper used or installation may cause damage to the monitor as well as
to the user.
WARNINGS:
z This monitor should be operated only at the correct power sources indicated on the
label on the rear of the monitor. If you’re unsure of the power supply in your residence,
consult your local dealer or Power Company.
z Use only the special power adapter that comes with this monitor for power input.
z Do not try to repair the monitor by yourself, as it contains no user-serviceable parts.
This monitor should only be repaired by a qualified technician.
z Do not remove the monitor cabinet. There are high-voltage parts inside that may cause
electric shock to human bodies.
z Stop using the monitor if the cabinet is damaged. Have it checked by a service
technician.
z Put your monitor only in a clean, cool, dry environment. If it gets wet, unplug the power
cable immediately and consult your local dealer.
z Always unplug the monitor before cleaning it. Clean the cabinet with a clean, dry cloth.
Apply non-ammonia based cleaner onto the cloth, not directly onto the glass screen.
z Do not place heavy objects on the monitor or power cord.
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety visual inspections
and the protection afforded by them cannot necessarily be obtained by using replacement
components rated for higher voltage, wattage, etc. Before replacing any of these
components read the parts list in this manual carefully. The use of substitute replacement
parts, which do not have the same safety characteristics as specified in the parts list, may
create shock, fire, or other hazards.
SERVICE NOTES
1. When replacing parts or circuit boards, clamp the lead wires around terminals before
soldering.
2. Keep wires away from high voltage, high temperature components and sharp edges.
3. Keep wires in their original position so as to reduce interference.
4. Adjustment of this product please refer to the user’ manual.

7. THEORY OF OPERATION
8.1 Inverter Board Circuit
The diagram of inverter board circuit is shown in Appendix (PWB-0420_01). The inverter
supplies power for backlight for the LCD panel.
8.2 Power supply Board Circuit
Please refer to 2.0 power Schematic sheet in Appendix. The 12Vdc from adaptor output is fed into
J800 as power regulation of U801 (BA9741F) input power and inverter main power on pin 1 of
CN830. The U801 can provide two independent power sources: a) The 5Vdc will be for main
board power. ; b) Another 10.5Vdc will output as audio power when audio Jack is inserted.
8.3 Scaling controller Board Circuit
The Scaling IC U400 is to convert the input signal from VGA, and SVGA to an XGA
resolution that the panel can acknowledge.
The scaling IC of gm2115 is a highly integrated System-on-a- Chip with very powerful functions,
including integrated 8 bit triple-channel ADC/PLL, programmable OnPanel timing controller,
embedded microcontroller with parallel ROM interface, OSD engine, sRGB compliance, and
PWM back light intensity control.
The Scaling IC features an integrated timing controller (TCON) that connects directly to
commercially available row and column drivers. All TCON signals OCLK, ECK, ORGB, ERGB,
OSP, ESP, OPOL, OINV, EINV on pin 119 to pin 128 of U400 have programmable drive strengths
and can be disabled to control Panel.
The flash memory chip of U410 contains codes via parallel data bus interface to
communicate with Scaling IC U400.
The DDC memory chip of U300 stores DDC data and the NVRAM chip stores timings and
setting data. Since the NVRAM has to get series number information from DDC chip, both their
SDA and SCL ports are connected together. In order to avoid conflict on I2C interface during the
DDC data transfer, the electrical switching of U301 is isolated and controlled by scaling IC pin
GPIO7.
8.4 Audio Circuit
Please refer to section 7, sound AMP Schematic. The audio Right/Left channels are fed into pin
6 /8 of sound AMP U701 (AN7522) while Audio plug is inserted in J701 jack. The sound output
amplitude will depend on this bias voltage on pin 9 of U701, which is always controlled by Q702.
When mute is activated, the Q703 will be forced to saturation to block sound output. When standby
is activated, the Q705/Q704 will also go to saturation to bypass the sound input signal to ground.
The sound outputs of U701 will drive speakers via CN701 connecter.
