7.10 Troubleshooting

7.10.1 How to use the troubleshooting

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 observed by the user:
• "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. The fans are not working.
• "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 recognized or not displayed on the screen.
• Image displayed on the screen is distorted, shows bands or stripes. In this case
something is wrong with the display unit. Contact Barco or your sales representa-
tive.

7.10.2 Fault and warning list

All faults and warnings are shown in the "Status controller" OSD submenu. The number of
faults and warnings are generated with respect to a node. The root node is "0" and will
always show when an error or warning occurs. In the table below, all nodes and error
codes which are relevant to the user are shown.
