Denon AVR-X6400H Service Manual

3-13. Error Code H1-16 failure detection procedure
Check the power supply voltage. (ARC IC)
Check item(45). Check the power supply voltage. :
Does the power supply voltage of the ARC IC [U3802] indicate the correct voltage (1.21V)?
The test points are as follows.
N3401
HDMI OUT
[MONITOR2]
L3805
1.2V
Check item(46). Check the power supply voltage. :
Check the power components [U3801] and the pattern on the sub-
strate.
If there is no problem, remove the ARC IC [U3802] from the sub-
strate and measure the voltage at the test point of check item (45).
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 (1).
If it does not work, replace the PCB.
Checking device. [U3802 : SiI9437]
NOYES
NOYES
YES
Checking the reset waveform. (ARC IC)
Check item(47). Checking the reset waveform :
Check the waveform.
Is the "RESET" waveform of the ARC IC [U3802] correct (like the
one shown in the diagram) when the power is turned on?
N3402
HDMI OUT
[MONITOR1]
U3802
R3805 : RESET
Check the reset circuit between
CPU [U6201] and ARC IC [U3802].
If there is no problem, the ARC IC
[U3802] is faulty.
Replace with a new device.
NO
