HDMI connection issues12.4
You encounter problems with HDMI
devices
The HDMI - HDCP procedure might take •
a few seconds before the TV shows the
picture from a device.
If the TV does not recognise the device and •
the screen shows no picture, try switching
from one device to another and back again
to restart the HDCP procedure.
If you experience intermittent sound •
disruptions, check the user manual of the
HDMI device to verify that output settings
are correct. Alternatively, try connecting
the channeling of the audio signal from the
HDMI device to the TV via an additional
audio cable.
If a HDMI-to-DVI adaptor or HDMI to DVI •
cable is used, check that an additional audio
connection is in place to complete the DVI
connection.
