Remedy
1.
Input the SDI signal to SDI 2 INPUT.
2.
Measure the C2451 waveform.
Connect and disconnect the SDI signal and check whether there is a change in
the C2451 waveform.
3.
•
When there is no change and the R2433 voltage is 3.3 V while the SDI
signal is input:
Replace IC2403
•
When the R2433 is at the ground level or unstable level while the SDI
signal is input:
Replace IC2202
