Denon AVR-X1600H Service Manual

3-7. Error Code H1-16 failure detection procedure
Check the power supply voltage. (ARC IC)
Check item(3-7.1.). Check the power supply voltage. :
Does the power supply voltage of the ARC IC [IC724] indicate the correct voltage (1.2V)?
The test points are as follows.
JK731
HDMI 4
[GAME]
JK741
HDMI 5
[MEDIA PLAYER]
L7364
Check item(3-7.2.). Check the power supply voltage. :
Check the power components [IC725] and the pattern on the sub-
strate.
If there is no problem, remove the ARC IC [IC724] from the substrate
and measure the voltage at the test point of check item (3-7.1.).
Is the power supply voltage correct (1.2V)?
Replace with a new device.
The power supply circuit is
faulty.
Replace the PCB.
Recheck from check item (3.1.).
If it does not work, replace the PCB.

YES
Checking the reset waveform. (ARC IC)
Check item(3-7.3.). Checking the reset waveform :
Check the waveform.
Is the "RESET" waveform of the ARC IC [IC724] correct (like the
one shown in the diagram) when the power is turned on?
The test points are fallows.
IC751
ARC_RST
Check the reset circuit between
CPU [IC751] and ARC IC [IC724].
If there is no problem, the ARC IC
[IC724] is faulty.
Replace with a new device.
Recheck from check item (3.1.).
If it does not work, replace the
PCB.
