Denon AVR-X1400H Service Manual

Check item(12). Check the power supply voltage.
:
Does the power supply voltage of the OSD[IC731]
indicate the appropriate voltage (1.8V, 3.3V)?
The test points are as follows.
IC731
93 pin
6 pin
1.8V
3.3V
Check item(13). Check the power supply voltage.
:
Check the power supply components [IC742,
Q7408, IC741, Q7410] on the substrate and pe-
ripheral pattern.
If there is no problem, remove the OSD [IC731]
from the substrate and measure the voltage at
the test point of check item (12).
Is the voltage correct (1.8 V or 3.3 V)?
Check the power supply voltage.

3-3. Error Code H1-07 failure detection procedure
NO
HDMI OSD[IC731] is faulty.
Replace with a new device.
Recheck from check item (1).
If it does not work, replace the PCB.
The power supply circuit is faulty.
Replace the PCB.
NOYES
YES
Check item(14). Checking the reset :
Check the CPU.
When the power is turned on, is the TP"A_RST" waveform correct (as
shown in the gure)?
IC731
