General
The top of the receiver is hot.
Phenomenon is specific to this amplifier. This is not a malfunction.
If [Control for HDMI] or [Network Standby] is set to [On], or
[Standby Through] is set to [On] or [Auto], the power for zone 2 is
turned on, the top of the receiver may become hot even while the
receiver is in standby mode. This condition occurs because current
is flowing in the internal circuits of the receiver, and this is normal.
Video
There is no picture or an unclear picture appears on the TV screen
or monitor, regardless of type of picture.
Select the appropriate input on the receiver (pages 11, 12).
Set your TV to the appropriate input mode.
Make sure that cables are correctly and securely connected to

HDMI output
The output of the HDMI video signals of the receiver may be set
to [OFF]. In this case, select [HDMI OUT A] or [HDMI OUT B] using
the HDMI OUT button on the remote control (page 13).
Sony recommends that you use an HDMI authorized cable or
HDMI cable made by Sony. Be sure to use High Speed HDMI
cables with Ethernet. Premium High Speed HDMI cable with
Ethernet, which can support bandwidths of up to 18 Gbps is
required for 4K/60p 4:4:4 8 bit and 4K/60p 4:2:0 10 bit, etc.
4K image
Depending on the TV or video equipment, 4K images may not
be displayed. Check the video capability and setting of your TV
or video device. Also, make sure to connect to the receiver to an
HDMI input jack of a TV or video equipment supporting 4K. You
have to connect an HDMI cable to an HDMI jack that supports
HDCP 2.2 when you use a playback device for 4K resolution
video content, etc.
HDR
HDR images may not be displayed in HDR mode when using
certain TVs or video equipment. Check the video capabilities
and settings of your TV and video equipment.
Some video equipment may not output HDR content in HDR
mode if [HDMI Signal Format] is set to [Standard format], even
when both the TV and video equipment support HDR and
bandwidths of up to 18 Gbps. In this case, set [HDMI Signal
Format] for the selected HDMI IN jack to [Enhanced format].
When [Enhanced format] is set as the signal format, use
Premium High Speed HDMI Cables with Ethernet, which can
support bandwidths of up to 18 Gbps.
