Troubleshooting
5.3 Troubleshooting
Should the display fail to function properly, the troubleshooting steps below may help to locate and
solve the problem:
• Check AC/DC adapter, battery and the power source.
• Minimize the configuration, e.g., remove additional peripherals and devices.
• Check the brightness settings of the display.
• Make sure the display is not in NVIS or Invisible Mode
• Set OSD default values (factory reset see chapter „OSD Menu“).
5.3.1 General troubleshooting
5.3.1.1 Display problems
The display is not working, nothing appears on the screen, display is too dark or bright.
• Please make sure, no power saving options are active (several settings might turn off the display
after a specific period of time).
• Please make sure the brightness settings are not set too dark or bright.
• Please make sure the backlight is not turned off.
Some pixels are not working (constant black/white/discoloured).
• A small number, depending on the screen size of the display, of not working pixels or sub pixels are
an intrinsic characteristic of all common LC displays. As long as the number of defective pixels are
not exceeding the number defined by pixel failure class II this is not considered a defect. This is a
physical limitation.
5.3.1.2 Touch screen problems
Touch screen can’t be used, no input possible
• Check if the touch screen has been recognized by the operating system’s device manager.
• Don’t use the 2 standard USB itnerfaces to connect to the touch screen, always use the RD-DVI
interface..
• Connect the RD-DVI interface with a dual Link DVI cable.
• Check if the connected PC is a RD-DVI compatible device or use a Y RD-DVI - DVI/USB cable.
