THANK YOU FOR A GOOD TRANSACTION, NICE COPY, CLEAR
;
Very Good! All the diagram are easy to read, and its complete.
;
This was an excellent source of detailed assembly information on a device which is at least 12 years old. A very lucky find, coupled with great service.
;
Excellent Service Manual and best price on the Internet. This Service Manual covers everything you could ever need including full circuit schematics, component layout diagrams, stripdown procedure and full parts list/breakdown. I needed this to carry out a modification to one of these headunits and this manual covered everything I needed. Fast delivery, processed within a few hours.

Thought I would never find a copy of the Technics SX-EN2 Service Manual until I found Owner-Manuals.com. Price was very fair and I received the download promptly. While a photocopy, it is quite readable and includes all the pertinent information and diagrams. Thank you Owner-Manuals!

Step 7: 1st DSP f
CN401 (Pin 20) RESET
j
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.
