YES
Check the I2C communication line. (HDMI SW2)
Check item(3-3.4.). Check the I2C communication line :
Check the CPU.
Is the "I2C" waveform of the TP near the HDMI SW2 [U1000]
correct (like the one shown in the diagram) when the power is
turned on?
U1000
I2C(HSCL)
I2C(HSDA)
HDMI SW2 [U1000] is faulty.
Replace with a new device.
Recheck from check item (3.1.)
If it does not work, replace the PCB.
Check item(3-3.5.). Check the I2C com-
munication line :
Check HDMI SW2 [U1000 or U1003],
HDMI Tx [U1001] and CPU [U1018]
patterns as well as soldering.
If there is no problem, go to the next
step.
NO
*The diagram shows an example.
(Signal patterns vary depending on the tim-
ing.)
Points for checking waveforms
- Crest value (3.3V normally)
- Signal change
- SCL frequency (400kHz normally)
Voltage scale : 1.0V/div
Time scale : 10us/div
HDMI SW2 [U1000] is faulty.
Replace with a new device.
Check the HDMI SW2.
Remove the damping resistor [R1061/R1062] of [U1000].
Is the "I2C" waveform correct?
Recheck from check item (3.1.)
If it does not work, replace the PCB.
