2. Service precautions

General Caution: Remove the power plug from the mains outlet before

removing any cover

• Opening the display must be done in a dust-poor environment, to
avoid dust particles on the glass plate or the panel.

• Opening the display must be done in a dust-poor environment, to
avoid dust particles on the panel.

Precautions for assembling the
display

• When assembling the display, place all the screws in their holes
without tightening them before they are all in place and the
metallic cover is resting without any mechanical stress on the
panel.

• Color spots on the display might be observed during operation if
any mechanical stress would be applied to the panel.

• When assembling the display, be sure to re-apply all the EMC
tapes and other EMC measures. Before applying the tape on metal
parts, degrease the metal using alcohol.

Handling Precautions for the LCD
panel

1. Since the panel surface is easily damaged, pay attention not to
scratch it.

2. Wipe off water drops immediately. Long contact with water may
cause discoloration or spots.

3. When the panel surface is soiled, wipe it with absorbent cotton or
any other soft cloth.

4. Since the panel is made of glass, it may break or crack if dropped
or bumped on hard surface.

5. Since CMOS LSI is used in the LCD panel, take care of static electric­ity and ensure human earth when handling.

6. Do not open nor modify the LCD panel assembly.

7. When you insert or remove the Signal Interface Connector, be sure
not to rotate nor tilt the Interface Connector of the LCD panel.

8. After installation of the LCD panel into the display frame, do not
twist nor bend the LCD panel even momentarily. Otherwise the TFT
Module may be damaged.

9. The Backlight lamp contains mercury. Do not throw it in the trash.
Dispose of it as required by local ordinances or regulations.

10. Do not display the same pattern on the LCD panel for more than
10 hours, to avoid image retention.

Cleaning Instructions

Nio 2-3-5 MP 5

3. Cleaning Instructions

Precautions • Caution: Remove the power plug from the mains outlet before

removing any cover

• Always wear clean protective gloves when handling and cleaning
the display

• Since the LCD panel and the front glass are easily damaged, pay
attention not to scratch them.

• Since the LCD panel is easily damaged, pay attention not to scratch
it.

• Wipe off liquid drops from the LCD panel immediately. Long con­tact with liquid may cause discoloration or spots.

• Since the LCD panel is made of glass, it may break or crack if
dropped or bumped on hard surface. Also, do not put any mechan­ical stress on the LCD panel.

The cleaning kit contains: • 3 soft, nonabrasive, dust-free cloths PN° B382816

• 2 pairs of gloves PN° B382818

• 1 touch-up paint bottle for the bezel PNº B1909152

• 1 touch-up paint bottle for the rear plastics PNº B1909151

What else do you need? • Neutral glass cleaning product to clean the glass plate.

E.g.: Cleareen, a product of Certified Laboratories.
Prefer products based on alcohol (Ethylalcohol or Isopropylalcohol)
above other neutral glass cleaning products.
Be sure that the product does not contain products of the 'DO NOT
USE' section below.

• Solution of 25% Isopropyl Alcohol and 75% de-ionized or distilled
water to clean the LCD panel.

As an alternative for the solution of IPA and water we can recom­mend “Klear Screen” (TM), a dedicated LCD display cleaner.

• A duster or dust remover to blow away dust. E.g.,. DUST OFF 67
(KONTAKT Chemie)

A dust remover is composed of a blend of compressed liquid gases
functioning as propellant. They provide a jet of dry inert gas that
acts like compressed air for a quick and safe removel of dust parti­cles and other dry contaminants on the surface of the lcd panel or
the glass panel.

DO NOT USE: • Strong alkalis lye

(Lye is a strong caustic alkaline solution of potassium salts,
obtained by leaching wood ashes. It is much used in making soap,
etc.)

•Acid

• Detergents with fluoride

•Detergents with ammonia

•Coarse tools:

- Detergents with abrasives

- Steel wool

- Sponge with abrasives

- Steel blades

- Cloth with thread made of steel

Cleaning Instructions

6 Nio 2-3-5 MP

Cleaning the glass plate- Outside
surface

Proceed as follows:

1. Take one of the nonabrasive cloths and put glass cleaner liquid on
it.

2. Clean the glass with the moist cloth.

3. Take another clean, dry cloth and wipe the glass dry.

Cleaning the glass plate- Inside
surface

If there are dust particles on the inside of the glass plate, proceed as
follows:

Spray with the duster gas onto the surface to be cleaned. For best
results, use the 'quick shot' method (Spray in short blasts). When the
aerosol is cooling down and the pressure is decreasing (internal
evaporation to restore the equilibrium in the aerosol can), wait a few
moments for the internal pressure to restore and repeat the spraying
action. Do not shake or move can during use.

Spraying the gas, the dust particles are blown away from the glass.
Do not blow them in the direction of the display.
Attention: The dust remover can contains a liquid gas. If you shake the

can or move the can too fast while spraying, you may blow drops of
liquid on the glass surface!

If this is the case, clean the glass as described in the § "Outside
surface" above.

Cleaning the LCD panel Proceed as follows:

1. If the LCD panel is dirty, take one of the nonabrasive cloths and
moisten the cloth with a solution of 25% Isopropyl Alcohol (IPA)
and 75% de-ionized or distilled water.

Do not use the same cloth as the one you apply glass cleaner to
for cleaning the glass.

2. Clean the panel with the moist cloth.

3. Take another clean, dry cloth and wipe the glass dry.

4. If there are dust particles on the LCD panel, blow them away by
using the dust remover. Do not blow them in the direction of the
glass plate.

Attention: The dust remover contains a liquid gas. If you shake the
can or move the can too fast while spraying, you may blow drops of
liquid on the panel surface!

If this is the case, clean the panel as described above.

Cleaning the plastics Clean the cabinet using a recognized cleaning product for medical

equipment. The cloth you use must be moist, not wet!
The cabinet has been tested for resistance to the following products:
Cidex, Betadine, Alcohol (Isopropyl and Ethyl), Ammonia-based

cleaners (Windex) and Aquasonic Gel.

6.6.9 After replacing the LCD/Backlight unit

After replacing the LCD / Backlight
unit, proceed as follows:

• It is necessary to calibrate the BLOS after replacing the LCD / Back­light unit. See chapter “BLOS calibration”.

BLOS calibration

32 Nio 2-3-5 MP

6.7 BLOS calibration

Introduction The calibration must be performed using the Minolta CA 110 / 210

measurement instrument, the calibration cover and the BARCO
software tool Mfdcontrol.exe (IMPORTANT- internal use only).

You must use the metal calibration cover because it is the only way to
ensure that the lens of the Minolta is in the correct position and at the
right distance of the panel.

The calibration is best performed in a darkened room.

Calibration set-up

Warm-up times • The Minolta must be warmed up for at least 15 min. before 0-cali-

bration of the CA- 110 / 210 will be started (is needed to have the
accuracy of 2% when you measure luminance values less then 5
cd/m²).

• The display must be warmed up for at least 2 hours without power
interruption.

Perform the CA- 110 / 210 0­calibration

For CA-110:

• Be sure the measuring probe is connected to the CA-110.

• Power-on the CA-110.

• Put the measuring/viewing selector in the viewing position (the
black spot on the knob must correspond with the white spot on
the measurement head).

In this position an image can be seen in the viewfinder, no light
will reach the sensor. The metal calibration cover must not be used
to darken the probe.

• Press the 0-cal button on the CA-110.

• Put the viewing selector back to the measuring position (no image
can be seen in the viewfinder). The 2 white spots corresponds in
the measuring position.

For CA-210:

• Be sure the measuring probe is connected to the CA-210.

• Power-on the CA-210.

• Turn the pointing ring to the “0-CAL” position.

• Do not point the probe in the direction of high luminance. Be sure
the pointing ring is set to “0-CAL” and not to “POINTER”.

• Press the “0-cal” button on the CA-210.

• After 0-calibration, turn the pointing ring to the “MEAS” position.

BLOS calibration

Nio 2-3-5 MP 33

Remarks: • If the ambient temperature changes, redo the zero calibration

The zero calibration can be checked in normal working position by
putting the measurement head on a flat surface, so no light will reach
the sensor and the display will show 0.00 cd/m². If the zero calibration
is not well performed, the message “offset error” will appear or a
value greater then zero will be measured.

Calibrate the BLOS • Connect the metal calibration cover to the display.

• Connect the CA 110 / 210 to the PC by a proper cable (see illustra­tion) and put it in the calibration cover.

• Start the program Mfdcontrol.exe (version Sept. 29 2003 at least).

• In the main menu, click the I-Guard button

• Click on Monochrome I-Guard

• In the next menu, the program will detect the BLOS.

Checking factory settings

36 Nio 2-3-5 MP

7.1 Checking factory settings

To check the factory settings: 1. Start the program Mfdcontrol.exe.

2. In the main menu, select the display of which you wish to check
the settings.

3. In the main menu, click on the button General.
The General information window appears

4. In the General information window, check the following items:

- Is the display serial number correct?

- Is the display stock number correct?

- Is the display type correct?

- Option DPMS must be checked.

- Option Stabilizer must be checked.

- Option Power LED must not be checked.

5. In the Backlight section at the bottom of the window, there is a
slider. Move the slider between minimum and maximum. The
backlight of the panel should change between minimum and
maximum. As another consequence, the Stabilizer option is dese­lected again.

6. Select the Stabilizer option again. The luminance value next to
the slider should go to the calibrated value (see Technical Specifi­cations) again.

Checking BLOS operation

Nio 2-3-5 MP 37

7.2 Checking BLOS operation

To check the BLOS operation: 1. Run the tool Mfdcontrol.exe (Version Sept. 29 2003 at least).

2. In the main menu, click on I-Guard.

3. In the I-Guard Calibration window, select Monochrome I-Guard.

4. In the Built in Sensor window, read out the Internal Device value.
This should be an acceptable value (see the technical specs - Lumi­nance).

Signature check

38 Nio 2-3-5 MP

7.3 Signature check

Introduction: This test should be performed after replacing an Interface Board. The

Signature Check tests a part of the Video circuit on the Interface Board.

To perform the Signature check: 1. Run the software tool Signature test.exe

2. In the menu, select the head and click on the button Measure. The
signature check is running now, displaying a number of test pat­terns.

3. After completion, the software returns if there were errors or not.
If there were errors, check the file Signature.log in the root direc­tory of the software tool.

How to judge the information from
the log file

The Signature test actually consists of 2 signature checks. Signature 1 is
calculated at the input of the FPGA on the Signal board. Signature 2 is
calculated at the outputs of the FPGA.

So, the knowledge of which of the signature checks is faulty can give
an indication of where the problem resides.

• If Signature 1 and Signature 2 are both faulty, there is a problem
that can reside on the imaging board in the PC, a problem with the
video cable, or a problem with the display’s Signal board. So, first
figure out if the imaging board or video cable is not faulty.

• In case Signature 1 should be OK, but Signature 2 is faulty, the
problem resides on the Signal board.

Visual checks

Nio 2-3-5 MP 39

7.4 Visual checks

Perform the following visual checks: • No scratches on the panel surface or plastics?

• No dust particles between the panel and the glass?

• When you disconnect the signal cable, does the display go into
stand-by? (power LED turns orange)

• Check the display quality by displaying some test patterns. A num­ber of useful test patterns are bundled in the software tool Gray­scale.exe.

Troubleshooting

44 Nio 2-3-5 MP

9. Troubleshooting

Sometimes if there is a problem, it is not obvious what is the origin of
the problem: The Interface board or the LCD panel.
There is a relatively easy way to test where lies the cause of the

problem. Therefore, replace the interface board by a spare board. This
is no problem if you do not perform a calibration.

If the problem persists after replacing the board, the cause is the LCD
panel. If the problem is solved after replacing the board, the cause is
the board.
