Important Safety Notice

1. Safety precautions

This monitor is manufactured and tested on a ground principle that a user’s safety comes first. However,
improper usage 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 you residence, consult your local dealer or Power
Company.

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 is 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 lean, cool, dry environment. If it gets wet, unplug the power cable immediately

and consult your closed 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 class screen.

z Do not place heavy object on the monitor or power cord.

2. 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.

3. Service notes

z When replacing parts or circuit boards, clamp the lead wires around terminals before soldering.

z Keep wires away from high voltage, high temperature components and sharp edges.

z Keep wires in their original position so as to reduce interference.

z Adjustment of this product please refers to the user’s manual.

(2) Lamp frequency which may produce interference with horizontal synchronous
frequency may cause line flow on the display. Therefore lamp frequency should be
detached from the horizontal synchronous frequency and its harmonics as far as
possible in order to avoid interference.

(3) Life time (Hr) is defined as the time when brightness of a lamp unit itself becomes
50% or less than its original value at the condition of Ta = 25±2°C and IL= 7.5mArms

(4) Designing a system inverter intended to have better display performance, power
efficiency and lamp reliability.

They would help increase the lamp lifetime and reduce leakage current.

a. The measurement should be done at typical lamp current.
b. The asymmetry rate of the inverter waveform should be less than 10%.
c. The distortion rate of the waveform should be √2 with ±10% tolerance.

- Inverter output waveform had better be more similar to ideal sine wave.

DD

to valid data at power ON.

DD

off at power Off.

DD

T5 : The time from valid data to B/L enable at power ON.
T6 : The time from valid data off to B/L disable at power Off.

 The supply voltage of the external system for the Module input should be the same

as the definition of V

DD

.

 Apply the lamp voltage within the LCD operation range. When the back light turns on

before the LCD operation or the LCD turns off before the back light turns off,

the display may momentarily show abnormal screen.

 In case of V

= off level,

DD

please keep the level of input signals low or keep a high impedance.

 T4 should be measured after the Module has been fully discharged between power off

and on period.

 Interface signal should not be kept at high impedance when the power is on.

04. TROUBLE SHOOTING

1. Common Acknowledge

z If you change the interface board, make sure that the U103, U105, U106, U108and U201 these five components also changed

to the new I/F board because there are program and data insides. If not, please re-write EDID or upload firmware into MCU via
VGA or DVI Cable.

z If you adjust clock and phase, please do it at the condition of Windows 98 or Windows 2000 shut down pattern.

z If you want to confirm the R.G.B. colors is normal or not, please do auto-balance under 32-grays scalar pattern.

z This LCM is analog/Dual interface. So if the entire screen is an abnormal color that means the problem happen in the analog

circuit part, if only some scale appears abnormal color that means the problem happen in the digital circuit part.

z If you check the H/V position, please use the crosshatch pattern.

z This LCM support more than 25 timing modes, if the input timing mode is out of specification, the picture may appears

abnormally.

z If brightness uneven, repairs inverter circuit or change a new panel.

z If you find the vertical line or horizontal line lost on the screen, please change panel.
