There Is No Picture From A Source Connected To An Hdmi In - Onkyo TX-NR545 Manual

Troubleshooting
There is no picture from a source connected to an HDMI IN
The input selector of this unit needs to be in the position that corresponds
to the jack where the player is connected.
While the Pure Audio (European, Australian and Asian models) listening
mode is selected only video signals input through HDMI IN can be output.
Check if "Resolution Error" is displayed on the main unit display when
video input via HDMI IN jack is not displayed. In this case, the TV does
not support the resolution of the video input from the player. Change the
setting on the player.
Reliable operation with an HDMI­to­DVI adapter is not guaranteed. In
addition, video signals from a PC are not supported.
Try switching off the DeepColor function. To turn off the DeepColor
function, simultaneously press the STRM BOX and ON/STANDBY
buttons on the main unit. While holding down STRM BOX, press
ON/STANDBY repeatedly until "Deep Color:Off" appears on the display.
To reactivate the DeepColor function, repeat the above described step
until "Deep Color:On" is appeared on the display.
