Check the I2C communication line. (HDMI Tx)
Check item(3-1.4.). Check the I2C communication line :
Check the CPU.
Is the "I2C" 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] is faulty.
Replace with a new device.
Recheck from check item (3.1.).
If it does not work, replace the PCB.
Check item(3-1.5.). Check the I2C com-
munication line :
Check HDMI Rx [U1000 or U1003],
HDMI Tx [U1039] and CPU [U1018]
patterns as well as soldering.
If there is no problem, go to the next
step.
Check the HDMI Rx2.
Remove the damping resistor
[R1169/R1170] of [U1003].
Is the "I2C" waveform correct?
Recheck from check item (3.1.)
If it does not work, replace the PCB.
Check the HDMI Tx.
Remove the damping resistor
[R1882/R1883] of [U1039].
Is the "I2C" waveform correct?
Check the HDMI Rx1.
Remove the damping resistor
[R1061/R1062] of [U1000].
Is the "I2C" waveform correct?
NO
NO NO
YES YES YES NO
