Checking the reset waveform (HDMI Rx/Tx)
Check the I2C communication line. (HDMI Rx/TX)
Check item(8). Checking the reset waveform :
Check the waveform.
Is the "I2C" waveform of the TP near the HDMI Rx (IC721 115pin)
correct (like the one shown in the diagram) when the power is
turned on?
115pin
Check item(9). Check the I2C communication line :
Check the CPU.
Is the "I2C" waveform of the TP near the HDMI Rx (U1000)
correct (like the one shown in the diagram) when the power is
turned on?
116pin
PSDA
114pin
PSCL
Check the reset circuit between
CPU (IC751) and HDMI Rx/Tx
(IC721).
If there is no problem, the HDMI
Rx (IC721) is faulty.
Replace with a new device.
Recheck from check item (2).
If it does not work, replace the
PCB.
The HDMI Rx/Tx
(IC721) is faulty.
Replace with a new
device.
HDMI SW (IC701)
is faulty. Replace with
a new device.
CPU(IC751)
is faulty. Replace with
a new device.
The HDMI Rx/Tx (IC721) is faulty.
Replace with a new IC.
Recheck from check item (2).
If it does not work, replace the PCB.
Check item(10). Check the I2C com-
munication line :
Check HDMI Rx/Tx (IC721), and
CPU(IC751) patterns as well as solder-
ing.
If there is no problem, go to the next
step.
Checking the HDMI SW.
Remove the damping resistor
R7136/R7138 of IC701.
Is the "I2C" waveform correct?
Recheck from check item (2).
If it does not work, replace the PCB.
Checking the HDMI Rx/Tx.
Remove the damping resistor
R7229/R7231 of IC721.
Is the "I2C" waveform correct?
NO
NO
NO
YES YES NO
Examples of conrmation waveform
*The diagram shows an example.
(Signal patterns vary depending on
the timing.)
Points for checking waveforms
