Safety precautions
2.3.1
Service safety precautions
WARNING:
Electric shock or fire hazard can be caused if critical components are replaced by non-
conforming components. These components are marked in this guide by a
sign. Replace
with conforming types only!
2.3.2
Product safety notice
WARNING:
Many electrical and mechanical parts in display units have special safety-related
characteristics. These characteristics are often not evident from visual inspection nor can the
protection afforded by them necessarily be obtained by using replacement components rated
for higher voltage, wattage, etc. Replacement parts that have these special safety
characteristics are identified in this data and its supplements and bulletins. Electrical
components having such features are identified by
or * on the schematics and on the
parts lists in this data and its supplements and bulletins. The use of a substitute replacement
that does not have the same safety characteristics as the recommended replacement part
shown in the parts lists in this data and its supplements and bulletins, may create shock or fire.
2.3.3
Earthing
WARNING:
The display unit must be earthed correctly. Verify that the power cable is plugged into a
standard 3-pin power outlet which is effectively earthed. When using extension cords, make
sure that they contain a grounded connection. If in doubt, contact a qualified electrician.
Ignoring this warning may lead to personal injury or death.

Fault finding procedure
If you detect a problem with your configuration, please check the items listed in
the user manual first.
In case of malfunction it is important to follow a certain troubleshooting
procedure. Some of the steps in this procedure may seem obvious.
Nevertheless, they are worthwhile checking. As a malfunction on one board
(module) can influence the behavior of other boards (modules), it might be
necessary to replace the same board (module) twice in the same
troubleshooting procedure.
6.2
Start here
Check the fault finding trees as presented in the User manual (included below).
If the fault finding trees of the User manual do not solve the problem, check the
following items listed in this diagnostics chapter:
•

Figure 8: IRIS board indicator LEDs
To verify if the IRIS board is defect, check the FPGA LEDs on the position n°1
and n°2. They light up orange after start-up and should go out when they are
configured. When one of those FPGA indicator LEDs does not go out, the IRIS
board is defect. The display unit should be send back to Barco.
The Freescale LED should light up green during operation. This LED is only for
development purposes and will not be present on the new version of the IRIS
board.

Diagnostics
6.7
Light diagnostics
In case the display unit is switched on, but nothing is displayed on the screen,
even after exhausting the “Nothing observed on the screen” fault finding tree in
the User manual:
•
Switch on the display unit. Check if the backlight switches on. (Even black
should become brighter)
If the backlight does not switch on:
•
Prepare the display unit for diagnostics:
3 Remove the power connection to the display unit
3 Remove back cover as described in “Removal and reinstallation back
cover”
3 Do not disconnect any cables inside the display unit
3 Reapply or switch on the power connection to the display unit
•
•
Check if LEDs D16 and D17 on the PIB are on. If not, replace PIB as
described in “Removal and reinstallation of the Power Interface Board (PIB)”
Check if the backlight is connected to the power (Connector J8 on PIB)
The fault is likely to originate in the IRIS board or the backlight board when:
•
•
the backlight has power but is never switched on
the backlight switches on but no menu or other picture can be made visible
on the screen
The IRIS board can only be replaced by Barco qualified personnel. Send the
display unit back to Barco.
6.8
Image diagnostics
In case the display unit shows the no valid sync message and the “Verify input
signal” fault finding tree from the User manual does not resolve the problem:
•
Source validation:
3 Check the video source on another input board or on another display
unit
3 Check if a different video source applied to the same input of this display
unit shows an image on the screen
3 Check whether your source is a validated input timing for your firmware
version. (User manual)
•
•
If the source is valid, try to resolve the problem by installing a new/different
input board as described in “ Removal and reinstallation of HDSDI board”
If installing a new/different input board is unsuccessful, the IRIS board is the
most likely to cause the problem. The IRIS board can only be replaced by
Barco qualified personnel. Send the display unit back to Barco.
6.9
Communication diagnostics
In case there is no communication with the display unit, and the problem is not
related to the network or the IP address, then the problem can be related to the
communication board. Replace the communication board as described in
“Removal and reinstallation of the communication board”.

Diagnostics
If installing a new communication board does not solve the issue, the IRIS board
is the most likely cause of the problem. The IRIS board can only be replaced by
Barco qualified personnel. Send the display unit back to Barco.
6.10
Color diagnostics
Each display unit is calibrated in the factory with the highest precision to the
correct white point, primaries and gamma. Two main issues can cause color
problems:
•
•
Defects
Matching between the display unit and other types of displays (e.g. CRT
technology based display units)
Defects
Make a visual inspection of the displayed image. Check for the problems
described below:
•
One horizontal stripe of the display unit has a different color than the rest of
the screen
•
The whole image as an extreme color (such as purple, green, red, etc…)
If one of the problems described above occurs, follow the diagnostics procedure
below:
•
•
Restart the display unit
If the problem persists or occurs frequently, try an update to the latest firm-
ware
•
If the above checks do not resolve the issue, the display unit will have to be
serviced and/or send back to Barco.
Matching problems
If the display color resembles the needed color (e.g. compared to a CRT), but is
slightly ‘off’ (white point slightly reddish, greenish, purplish etc) from the
expected color, several settings can be checked to obtain a better matching. The
points below describe the possible steps that can be taken to reach the desired
color matching:
•
•
Make sure the display is warmed up (wait at least 20 minutes)
Press the CAL button and select the appropriate color space (e.g. Rec.709
for HD content, EBU 3213 for European SD content, SMPTE C for US SD con-
tent, etc…)
•
•
Check in the color working space menu (ꢄ) if the white point, gamma and/
or RGB primaries correspond to the standard values as specified in the User
Manual
The white point of the RHDM can still differ slightly with respect to another
display unit (e.g. a reference CRT monitor). Try to manually adjust the white
point of the display unit. Differences in white point can be related to:
3 different technologies
3 different calibration sensors
3 metameric difference of a human observer because of difference
between LED and phosphor spectra

Diagnostics
NOTE:
When the colors of the display unit seem ‘greenish’, decrease the y coordinate of the white
point from 0.329 down to a value as low as 0.315 and increase the x coordinate of the white
point from 0.3127 up to a value of 0.315.
IMPORTANT:
Do not measure the display unit with a colorimeter such as DK Technologies, Konica Minolta CA
210, Thoma, Klein K-10 etc. These probes will give erroneous results because the display unit
is a LED-based display. The color filters do not match. It is recommended to use a spectropho-
tometer for reliable results.
NOTE:
The CRT can be measured with a corresponding probe (such as mentioned above). Use the
obtained values to manually adjust the (x,y) coordinates of the display unit.
If the above checks do not resolve the color matching issue, contact Barco for
further assistance. A display swap would probably not solve the problem as the
problem is related to the difficulty in matching different technologies.
