6.1 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:
Check if the right connections are present: See the section “Connections”
Check if the issue is related to one of the following cases: 3 In case the monitor power LED stays off, or there is no image even if the
power LED is green.: See the section “Power diagnostics”
3 In case the monitor is switched on, but nothing is displayed on the
screen: See the section “Light diagnostics”
3 In case the monitor keeps showing the no valid sync message: See the
section “Image diagnostics”
3 In case there is no communication with the monitor, and you are sure
there are no network or IP address issues: See the section “Communica­tion diagnostics”
3 In case color is not correct or color is unstable: See the section “Color
diagnostics”

6.3 Fault finding trees User Manual

6.3.1 Description fault finding trees

When the display unit is not working properly or the operation instructions do not solve the problem, the troubleshooting may allow the user to identify the source of the problem.
The fault finding trees are divided into three structures. They should be checked according to the problem observe d by th e us er:
“No power” fault finding tree: The display unit does not seem to be powered. No LEDs are burning and nothing is observed on the screen.
“Nothing observed on the screen” fault finding tree: The display unit is pow­ered but no image is shown on the screen.
“Verify input signal” fault finding tree: The display unit works correctly, but the applied input signal is not reco g nized or not displayed on the screen.

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 resolv e 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”.

Page 25
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…)
Diagnostics
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 firm­ware
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 con­tent, etc…)
Check in the color working space menu ( 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 CR T 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
) if the white point, gamma and/
Barco - RHDM-1701 - Maintenance Manual ______________________________________________ 25
Page 26
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 spectropho­tometer 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.

10.1 Cleaning precautions

Take care not to damage or scratch the LCD surface. Be carefull with rings,
jewellery and rough materials. Handle the LCD with care to avoid scratches.
Do not apply pressure on the LCD surface.
Do not apply or spray liquid directly to the LCD surface or cover as excess
liquid may cause damage to internal electronics. Instead apply the liquid to the cleaning cloth.
Avoid dirt of fingerprints, oil, and fat staini ng on the LCD surface as they will
harm the LCD. Remove dirt by following the cleaning instructions below.

10.2 Cleaning instructions (for CIVIL)

Before cleaning:
Switch off the display unit.
Remove the power cord from the mains.
Cleaning the LCD screen:
Wipe the screen surface with a soft cleaning cloth.
To remove stains, use a damp cloth with non-aggressive cleaning products:
3 Do NOT use abrasive cleaning agents, glass cleaner or tissue paper. 3 Do NOT use alcohol/solvents at higher concentration > 5%. 3 Use non-aggressive cleaning products (water or a solution of distilled
water and IsoPropyl Alcohol).
Do not rub or push on the LCD screen. Rubbing with tissue can degrade the
performance of the LCD screen.
Cleaning the cover:
Use a soft cloth to remove dust. If necessary, a vacuum cleaner can be used
to clean the ventilation openings (if applicable).
Use a damp cloth (if necessary with some mild detergent) to remove stains.
Do not use a scouring pad, or other tools that my scratch and damage the
