Denon AVR-X2400H Service Manual

Checking operation between the HDMI (Front HDMI Buffer) and the player
b
In order to check, connect the player to the HDMI terminal and congure the player as AVR source.
Check the sound output while turning on the player.
Check item(47). Check the power supply voltage. :
Does the power supply voltage of the Front HDMI FFC base [N1000] indicate the correct voltage (5V)?
The test points are as follows.
N1000
17pin 5V
Check item(49). Checking the 5V status of the register :
Send the following command from Termite.exe.
Send the command "i 002E 00FF 0001".
Move to the branch destination according to the value returned.
Check the power supply voltage. (HDMI Rx)
Checking the +5V/DDC status register (Front HDMI Buffer)
Check item(48). Check the power supply voltage. :
Check the FETSW [Q1058] and peripheral pattern.
If there is no problem, remove the Front HDMI FFC from the substrate and measure the voltage
at the test point of check item (47).
Is the power supply voltage correct (5 V)?
Front HDMI Buffer [U3000] is faulty.
Replace with a new device.
Example
i 002E 00FF 0001
"00"
(Detection of 5V is not OK.)
"00 or 04"
(Detection of DDC is not OK.)
"88 or 80"
(Detection of 5V is OK)
"22"
(Detection of DDC is OK)
Go to check item (51)
Go to check item (51)
Go to check item (53)
Replace the FET SW [Q1058] and recheck from
check item (47).
If it does not work, replace the PCB.
Recheck from check item (2).
If it does not work, replace the PCB.
3-11. Front HDMI Buffer IC [AD8195] failure detection procedure
YES
YES
NO
NO
Check item(50). Checking the status of the register :
Send the following command from Termite.exe.
Send the command "i 002B 00B4 0001".
Move to the branch destination according to the value returned.
