Please check the following components:
Check your playout device by replacing media type, channel or connecting another playout device to your screen
Connect your playout device to another source input port (HDMI1, HDMI2...)
Check/replace your wiring
Make sure your screens power adaptor is connected to the same electrical circuit (phase) with your playout device(s). The easiest way to assure that is by connecting all devices (screen, playout devices, receivers...) to the same electrical wall socket
Disconnect all playout devices from tour screen and open the OSD Menu. If still those stripes appear on your screen please contact us.
