CN401 (Pin 16)

For the following diagnosis, a digital oscilloscope must be used. SPICLK
A

Is the logic of RST_1 "H" ?

No

Check the output from the DIGITAL MOTHER Assy.

w

Yes R139

Is the clock signal output while the voltage at SPIDS_1 is "L"?

No

Check the output from the DIGITAL MOTHER Assy.

y

Yes R144

Is the logic of RST_1 "H" ? Yes

No

Check the resistors and patterns in the path.

Is the clock signal output while the voltage at SPIDS_1 is "L"?

No

Check the resistors and patterns in the path.

B

Is the logic of RST_1 maintained at "H"? (Does it fall to become "L" periodically?)

k
No It is likely a boot error. (It is very difficult to diagnose which peripheral part of the DSP is in failure.)

Yes CN401 (Pin 19) MOSI

g

Yes R134 REQ_1

Is the clock signal output while the voltage at SPIDS_1 is "L"?

No

Check the output from the DIGITAL MOTHER Assy.
C

z
Does the logic become "H" for a moment when the input stream is changed? No The 1st DSP is in failure. Replace it.

Yes R146

g

Yes CN401 (Pin 21)

Is the clock signal output while the voltage at SPIDS_1 is "L"?

No

Check the resistors and patterns in the path.

AA
Does the logic become "H" for a moment when the input stream is changed? No Check the resistors and patterns in the path.

Yes R142 MISO

h

Yes CN401 (Pin 17) SPIDS_1

Is the clock signal output while the voltage at SPIDS_1 is "L"?

D

No The 1st DSP is in failure. Replace it.

i
Does the logic become "L" for a moment when the input stream is changed? No Check the output from the DIGITAL MOTHER Assy.

Yes CN401 (Pin 18)

x

Yes R137

Is the clock signal output while the voltage at SPIDS_1 is "L"? Yes

No

Check the resistors and patterns in the path.
E

Does the logic become "L" for a moment when the input stream is changed? Yes

No

Check the resistors and patterns in the path.

It is very difficult to diagnose which part is in failure.
