Denon AVR-X6400H Service Manual

3-2. Error Code H1-02 failure detection procedure
Check the power supply voltage. (HDMI SW1)
Check item(11). Check the power supply voltage. :
Does the power supply voltage of the HDMI SW1 [U2401] indicate the correct voltage (1.1V, 3.3V)?
The test points are as follows.
HDMI SW1
U2401
1.1V
3.3V
112 pin
38 pin
Check item(12). Check the power supply voltage. :
Check the power components [U3604] and the pattern on the sub-
strate.
If there is no problem, remove the HDMI SW1 [U2401] from the sub-
strate and measure the voltage at the test point of check item (11).
Is the voltage correct (1.1V or 3.3V)?
Replace with a new device.
check item (1) again after replacing [R2460/R2461] with a new
resistor.
If there is still a problem, the HDMI SW1 [U2401] is faulty.
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.
Recheck from check item (1).
If it does not work, replace the PCB.
Checking device. [U2401 : MN864788]
NOYES
NOYES
YES
Checking the reset waveform. (HDMI SW1)
Check item(13). Checking the reset waveform :
Check the waveform.
Is the TP waveform of the TP near the HDMI SW1 [U2401] correct
(like the one shown in the diagram) when the power is turned
on?
HDMI SW1
U2401
RESET
Check the reset circuit between
CPU [U6201] and HDMI SW1
[U2401].
If there is no problem, the HDMI
SW1 [U2401] is faulty.
Replace with a new device.
NO
