Denon AVR-X2600H Series User Manual

Check the power supply voltage. (HDMI Tx)
Check item(3-1.1.). Check the power supply voltage. :
Does the power supply voltage of the HDMI Tx [U1039] indicate the correct voltage (1.1V, 3.3V)?
The test points are as follows.
HDMI Tx
U1039
112pin
38pin
1.1V
3.3V
Check item(3-1.2.). Check the power supply voltage. :
Check the power components [U1064/U1066] and the pattern on
the substrate.
If there is no problem, remove the HDMI Tx [U1039] from the sub-
strate and measure the voltage at the test point of check item (3-
1.1.).
Is the voltage correct (1.1V or 3.3V)?
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.

Checking the reset waveform. (HDMI Tx)
Check item(3-1.3.). Checking the reset waveform :
Check the waveform.
Is the "RESET" waveform of the TP near the HDMI Tx [U1039]
correct (like the one shown in the diagram) when the power is
turned on?
HDMI Tx
U1039
RESET
Check the reset circuit between
CPU [U1018] and HDMI Tx
[U1039].
If there is no problem, the HDMI
Tx [U1039] is faulty.
Replace with a new device.
Recheck from check item (3.1.).
If it does not work, replace the
PCB.
NO
