Remedies
• Check that the device is connected and switched on.
• Adjust the brightness and contrast.
• Check the input signal.
• Check the connection between the screen and the device. Unplug
the power cord, wait one minute, and plug the device back in.
• Check the screen selection.
• Check that the video input cable is plugged in correctly.
• Possible power fluctuations, connect the device to another power
source.
• Check for magnetic devices in the immediate vicinity (wireless
receiver, AC transformer, etc.).
• Check that the video input cable is plugged in correctly.
• Check the video input voltage range (V-sync Max. 75Hz, H-sync
Max.48.08KHz).
• Make sure the video cables are connected correctly.
• Check the connection to the speaker.
• The sound might be off (mute), try adjusting the volume.
• Check if the remote control signal is blocked by an object or light.
• Check the batteries and replace them with new ones if necessary.
• Check the correct setting of upstream receiving devices (satellite
receivers, DVB-T receivers).
• Unplug the power cord, wait one minute and plug the device back
in.
• The cable cross-section must be at least 2 times 0.75 mm2, for
cable lengths of 5 m, at least 2 times 2.5 mm2.
• Make sure that the +/- voltage is correct (observe symbol on sti-
cker). Reversing the polarity of the device will void the warranty.
