Interpolated Resolutions: When resolutions are shown that are lower than the pixel count of the
LCD module, text may appear different. This is normal and necessary for all current flat panel technologies when displaying non-native resolutions full screen. In flat panel technologies, each dot on the screen is actually one pixel, so to expand resolutions to full screen, an interpolation of the resolution must be done.

Troubleshooting
No picture
• The signal cable should be completely connected to the display card/ computer.
• The display card should be completely seated in its slot.
• Check the Vacation Switch should be in the ON Position. Front power
Switch and computer power switch should be in the ON position.
• Check to make sure that a supported mode has been selected on the display card or system being used. (Please consult display card or system manual to change graphics mode.)
• Check the monitor and your display card with respect to compatibility and recommended settings.

Power Button does not respond
• Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.
• Check the Vacation Switch on the left hand side of the monitor.
Image persistence
• Image persistence is when a “ghost” of an image remains on the screen even after the monitor has been turned off. Unlike CRT monitors, LCD monitors’ image persistence is not permanent.
To alleviate image persistence, turn the monitor off for as long as an image was displayed. If an image was on the monitor for one hour and a “ghost” of that image remains, the monitor should be turned off for one hour to erase the image.
NOTE:
As with all personal display devices, NEC-Mitsubishi Electronic
Displays recommends using a screen saver at regular intervals whenever the screen is idle.

TCO’99
This is a translation of the original English TCO'99 document.
MultiSync LCD1550ME White Model (L15XA231-BN)
Congratulations! You have just purchased a TCO’99 approved and labeled product! Your choice has provided you with a product developed for professional use. Your purchase has also contributed to reducing the burden on the environment and also to the further development of environmentally adapted electronics products.
Why do we have environmentally labelled computers?
In many countries, environmental labelling has become an established method for encouraging the adaptation of goods and services to the environment. The main problem, as far as computers and other electronics equipment are concerned, is that environmentally harmful substances are used both in the products and during the manufacturing.
Since it has not been possible for the majority of electronics equipment to be recycled in a satisfactory way, most of these potentially damaging substances sooner or later enter Nature.
There are also other characteristics of a computer, such as energy consumption levels, that are important from the viewpoints of both the work (Internal) and natural (external) environments. Since all methods of conventional electricity generation have a negative effect on the environment (acidic and climate-influencing emissions, radioactive waste, etc.), it is vital to conserve energy. Electronics equipment in offices consume an enormous amount of energy since they are often left running continuously.
What does labelling involve?

Environmental Requirements
Flame retardants
Flame retardants are present in printed circuit boards, cables, wires, casings and housings. In turn, they delay the spread of fire. Up to thirty percent of the plastic in a computer casing can consist of flame retardant substances. Most flame retardants contain bromine or chloride and these are related to another group of environmental toxins, PCBs, which are suspected to give rise to severe health effects, including reproductive damage in fisheating birds and mammals, due to the bioaccumulative* processes. Flame retardants have been found in human blood and researchers fear that disturbances in foetus development may occur.
TCO’99 demand requires that plastic components weighing more than
25 grams must not contain flame retardants with organically bound chlorine and bromine. Flame retardants are allowed in the printed circuit boards since no substitutes are available.
Lead**
Lead can be found in picture tubes, display screens, solders and capacitors. Lead damages the nervous system and in higher doses, causes lead poisoning.
TCO’99 requirement permits the inclusion of lead since no replacement has yet been developed.
English-27
1-28
Cadmium**
Cadmium is present in rechargeable batteries and in the colourgenerating layers of certain computer displays. Cadmium damages the nervous system and is toxic in high doses.
TCO’99 requirement states that batteries, the colourgenerating layers of display screens and the electrical or electronics components must not contain any cadmium.
Mercury**
Mercury is sometimes found in batteries, relays and switches, Mercury damages the nervous system and is toxic in high doses.
TCO’99 requirement states that batteries may not contain any Mercury.
It also demands that no mercury is present in any of the electrical or electronics components associated with the display unit.
CFCs (freons)
CFCs (freons) are sometimes used for washing printed circuit boards.
CFCs break down ozone and thereby damage the ozone layer in the stratosphere, causing increased reception on Earth of ultraviolet light with consequent increased risks of skin cancer (malignant melanoma).
The relevant TCO’99 requirement; Neither CFCs nor HCFCs may be used during the manufacturing and assembly of the product or its packaging.
* Bio-accumulative is defined as substances which accumulate within living organisms.
** Lead, Cadmium and Mercury are heavy metals which are
Bioaccumulative.

MultiSync LCD1550ME Black Model (L15XA231-BNBK)
Congratulations! You have just purchased a TCO’95 approved and labeled product! Your choice has provided you with a product developed for professional use. Your purchase has also contributed to reducing the burden on the environment and also, to the further development of environmentally adapted electronics products.
Why do we have environmentally labelled computers?
In many countries, environmental labelling has become an established method for encouraging the adaptation of goods and services to the environment. The main problem, as far as computers and other electronics equipment are concerned, is that environmentally harmful substances are used both in the products and during the manufacturing.
Since it has not been possible for the majority of electronics equipment to be recycled in a satisfactory way, most of these potentially damaging substances sooner or later enter Nature.
There are also other characteristics of a computer, such as energy consumption levels, that are important from the viewpoints of both the work (Internal) and natural (external) environments. Since all methods of conventional electricity generation have a negative effect on the environment (acidic and climate-influencing emissions, radioactive waste, etc.), it is vital to conserve energy. Electronics equipment in offices consume an enormous amount of energy since they are often left running continuously.

4-2
4) If there is no particular operation, an all white screen (255/255 gradation) is displayed.
5) Operate the(
4) RIGHT and (3)LEFT keys in this state. Then, operation for the gradation becomes possible. It is also possible to change the pattern by operating the (
4)RIGHT and (3)LEFT keys.
6) When withdrawing from the aging mode, press the EXIT key.
During operation in the aging mode, the power save mode is not assumed. The LED maintains the green display.
At the time of adjustment of this model, a suggestion may be given to enter the service (factory) mode. This will be explained below.
(1) Service mode:
1) In the “display mode” menu, press the (+) and (
−) LEFT keys at the same time while pressing the
RESET key.
2) When the NEXT key is pressed under the condition that the WARNING screen is displayed, the mode moves to the SERVICE mode. At that time, the LED is kept lit in green. The OSM AUTO-OFF function is disabled.

3. Set adjustments
3.1. Measuring instruments to be used
The measuring instruments considered necessary for the adjustment of the LCD1550ME set are specified below.
1) Equipment that can generate an output of the adjusted VG-819 unit or equivalent
3.2. Power source voltage
100 - 120V/ 220 - 240V
± 5%, 50/60Hz
3.3. Electrification
1) Make connections according to the mode intended for VG-819 cable setting.
2) Turn on the POWER switch of the VG-819 unit.
3) Connect an AC power cable to the unit under inspection.
4) Confirm that the vacation switch (seesaw switch) at the left side of the unit being inspected has been moved to the “I” side, and turn the POWER switch ON at the right side of the front.
5) The LED of the unit under inspection is lit in amber. (In the middle of signal discrimination)
6) After the completion of signal discrimination, the LED is lit in green.
Note 1: When the POWER source switch is turned on for the first time, the initialization of EEPROM is effected regardless of the ON/OFF position of the POWER switch. In this period (about 1 minutes), the POWER switch must not be moved to the ON or OFF position. Upon the completion of the initialization, a normal screen is displayed. (If no signal input is entered, the information OSM is displayed.) If the screen is not displayed for more than 5 minutes after the electrification, however, this seems to have resulted from failure in the initialization of EEPROM.
Such a condition is regarded as NG.
Note 2: Connections for the connectors should be carried out always under the condition that the AC
POWER cord plug has been pulled out.
3.4. Input signals
Refer to Paragraph 3.6.1 for each adjustment item.
3.5. POWER ON and signal input
1) Turn on the vacation switch located on the side of the main unit (the power supply for the signal generator turned off) and turn on the power circuit by pressing the POWER key on the front panel.
Confirm in this case that the LED is lit in amber. When the power supply is turned on for the first time after the completion of PWB assembly, do not turn off the power supply for at least 10 seconds because initialization is required to be performed.
2) Turn on the power supply of the signal generator and enter an input of Signal 1. Confirm that the LED is turned from amber to green.
* If this LED is not lit in green at that time, it is regarded as a defective LED.
3) Prior to adjustments, execute the factory reset procedure without fail. The method of this action is described below. a) Display the SERVICE menu and adjust the cursor to the item of [FACTORY RESET]. b) Enter a signal 2 input of VGA 640x480(Solid all white pattern). c) Press the (+) PLUS or (-) MINUS keys to execute the factory reset procedure.

1. Audio circuit (Circuit diagrams Main PWB)
1.1 Audio input
The audio signal input received from the audio input terminal (JK011) is applied to the amplifier I001 of 4
(L-CH) and 9 (R-CH) through the low-pass filter consisting of R040, R041, R042, R043, C040 and C041.
In this amplifier, controls of Volume, and mute are conducted. The audio signal controlled at the pin 6 determines the attenuation of output of the amplifiers. Since then, the signal is output to the jack P003.
1.2 Audio output
The audio signal is output from the Audio output terminal (P003) of the jack board to the internal speaker system.
2. Power supply (Circuit diagrams MAIN PWB)
1. Line filter consists of C801, T801, C803, C804. It eliminates high frequency interference to meet EMI’s requirement.
2. Rec & Filter
Bridge diode D801 converts AC source into pulsed DC. This pulsed DC is smoothed and filtered by C805.
R802 is an NTC ( negative thermal coefficient ) resistor, used to reduce inrush current to be within safe range.
3. Power transformer :
T802 converts energy for square wave from power source C805 to secondary side to generate +12V and
+5V.
4. Output :
The square wave from T802 is rectified by D809, D810, then filtered by C817, C822 to generate +12V and +5V respectively.
4.1 A 5V power supply for LCD module, CPU and logic is generated from the power source.
4.2 I310 : 3-terminal regulator
A 3.3V power supply for I306 analog is generated from the 5V source.
4.3 I310 : 3-terminal regulator
A 3.3V power supply for I306 digital is generated from the 5V source.
Q303, Q304 ON/OFF control for LCD Module
ON/OFF control is performed for power ON/OFF and also for the power saving sequence.
5. Driver : Q803
If the electrical potential of gate is larger than source by about 10 volts, Q803 turns on.
6. FB :
Negative feedback CKT consists of photo coupler I802 and adjustable regulator I803. It can maintain output voltages +5V and +12V at a stable level.
7. PWM :
7.1 Start : When power is turned on, R805, R803 conducts due to bias from C805. C807 is charged a 16 volt and a starting current to pin 7 of I801. I801 starts to oscillate and outputs a pulse train through pin 6 to drive Q803.
7.2 OPP : When Q803 turns on, C805 supplies a linearly increasing triangle current through the primary inductance of T802 to the driver Q803, once the peak value of this current multiplied by R811 exceeds1 volt, pulse train will be shut down immediately to protect Q803, T802 from being burned out.
7-2
7.3 Regulation : If output voltage +5V goes up, the R terminal of I803 gets more bias, accordingly photo transistor and photo diode flows more current. The voltage of pin 2 goes up too, making the pulse width of pin 6 to become narrower. So the output voltage +5V will be pulled down to a stable value.
7.4 OVP : If +5V goes up too much, the induced voltage on pin 4 of T802 becomes large also. Suppose that it is over 18 volts, ZD801 conducts, pin 3 of I801 is pulled up over 1 volt. The pulse train at pin 6 goes down to zero, shutting Q803 off completely.
7.5 SCP : If output terminal is short to ground, photo transistor does not conduct, hence Q806 does not conduct neither. The reference voltage +5V at pin 8 begins to charge on C829 and activates Q806 to conduct either. Then oscillation of I801 is stop, shutting Q803 off completely.

9. CPU circuit (Circuit diagram MAIN PWB)
I302 (MTV312MV64) functions as the CPU.
The source voltage for the device is 5.0V and the system clock frequency is 20MHz.
9.1 Detection of POWER switch status
The CPU identifies the ON status of the two power supplies. The identification is made when the power supply is turned off. For example, if the power supply is turned off with the POWER switch, the POWER switch must be turned on when activating the power supply again. If the power supply is turned off by pulling out the power cord, then this power supply can be turned on by connecting the power cord, without pressing the POWER switch.
9.2 Display mode identification
9.2.1 Functions
(1) Display mode identification
The display mode of input signal is identified based on Table 1, and according to the frequency and polarity (HPOL, VPOL) of horizontal or vertical sync signal, presence of the horizontal or vertical sync signal, and the discrimination signal (HSYNC_DETECT, VSYNC_DETECT).
When the mode has been identified through the measurement of horizontal and vertical frequencies, the total number of lines is determined with a formula of “Horizontal frequency / Vertical frequency =
Total number of lines. “Final identification can be made by examining the coincidence of the obtained figure with the number of lines for the mode identified from the frequency.
When the detected frequency if the sync signal has changed, the total number of lines should be counted even through it is rge identified frequency in the same mode. Then, it is necessary to examine whether the preset value for the vertical display position of Item 4-3 has exceeded the total number of lines. If exceeded, a maximum value should be set up, which does not exceed the vertical display position of Item 4-3.
7-4
(2) Out of range
This out-of-range mode is assumed when the frequency of the horizontal / vertical signal is as specified below.
Vertical frequency : Below 56.2Hz or above 75.1Hz
Horizontal frequency : Below 31.5KHz or above 60KHz
(3) Power save mode.
The power save mode is assumed when the horizontal / vertical signals are as specified below.
If there is no horizontal sync signal input.
If there is no vertical sync signal input.
If the horizontal sync signal outside the measuring range of gmZAN1.
If the vertical sync signal outside the measuring range of gmZAN1.
