Denon AVR-X6400H Service Manual

Check item(17). Check the power supply voltage.
:
Does the power supply voltage of the GUI [U2800]
indicate the appropriate voltage (1.8V, 3.3V)?
The test points are as follows.
U2800
1.8V
3.3V
L2802 L2815
Check item(18). Check the power supply voltage.
:
Check the power supply components (U3603,
Q3696) on the substrate and peripheral pattern.
If there is no problem, remove the GUI [U2800]
from the substrate and measure the voltage at
the test point of check item (17).
Is the voltage correct (1.8V or 3.3V)?
Check the power supply voltage.
