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 burn-
ing 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 sig-
nal 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 representative.
