Flowchart of troubleshooting the HDMI block
A
No video or audio output from the
equipment supporting HDMI
(in a case of HDMI input/output)
When a player
supporting HDMI is directly
connected to a monitor supporting
HDMI (with an HDMI cable) is
there any abnormality?
B
Check whether
HDMI authentication has
been completed between the
player supporting HDMI and this unit
according to the HDMI indicator on the front panel:
Lit: Authentication OK
Flashing: Authentication in progress
Unlit: Authentication failed
C
Check with other input sources:
Video input (composite, component)
Audio input (analog, digital)
In a case of a failure in the audio
system, input a signal from the
HDMI input then check it at the SP
D
output.
Diagnose the unit by referring to
the sections on how to diagnose
and troubleshoot the HDMI block,
described on the subsequent pages.

The player or monitor supporting HDMI (or the HDMI
cable) may be defective. Or there may be wrong
settings of some equipment.

Not the HDMI block, but either the DSP block or the analog line is
defective, and which is defective must be judged:
• See "7.1.3 Troubleshooting the DSP Block."
• Check the analog line.
See "3. How to diagnose the product with the Power Amp Block
removed" in "7.1.10 DISASSEMBLY."
