Denon AVR-X6300H Service Manual

Check item(72). Checking the reset :
Check the CPU.
Is the waveform of the TP near the GUI (U2800) correct (like the one
shown in the diagram) when the power is turned on?
U2800
RESET
Check item(73). Check the I2C communication line :
Check the CPU.
Is the TP waveform of the TP near the HDMI Decoder (U2000) cor-
rect (like the one shown in the diagram) when the power is turned
on?
U2000
I2C(AVSDA)
I2C(AVSCL)
Check item(74). Check the I2C communication line :
Check GUI (U2800), HDMI Decoder (U2000) and CPU(U6201) patterns as well as soldering.
If there is no problem, go to the next step.
Check the HDMI Decoder.
Remove the damping resistor (R2031) of
HDMI Decoder (U2000).
Is the "I2C" waveform correct?
The GUI (U2800) is faulty.
Replace with a new device.
Checking the reset waveform.
Check the I2C communication line.
