Easy to order the manual. Good quality and fast delivery.

The Service Manual for Sansui AU-9500 was very helpfull, in complete and in good printable condition.
Thanks.

Dear Sir,
Document is original service document of sharp. I had a problem with the door contacts. Fuses where blown. With the manual in a few minuts is was clear what the problem was.
Manual was of great help.
With kind regards,

The scan is clear and well readable with very few weaker spots, usually on black background with white letters, but with enough zoom those spots can be read.
Printout is clear, the manual is complete and has all pages scanned.
I would give 5 stars, except that it is not in color, and the schematic and PCB pages are scanned on multiple pages. The document is locked (except printing) so the pages can not be extracted to compose them together for printing on the large plotter
It is worth the price tag.

let's say first that i do not need to have a credit for my opinion, i am a retired sparkie and i voluteerd to fix an electronic device for a local "Youthgroup",as no diagram was present i checked the "net" and gambled on this site and paying some fee via PayPall, i was gladly surprised that the manual arrived as was stated, GOOD SHOW, and best wishes, John

For the following diagnosis, a digital oscilloscope must be used. SPICLK
Is the logic of RST_1 "H" ?
No
Check the output from the DIGITAL MOTHER Assy.
Is the clock signal output while the voltage at SPIDS_1 is "L"?
No
Check the output from the DIGITAL MOTHER Assy.
m
Yes R122
s
Yes R124
B
Is the logic of RST_1 "H" ? Yes Is the logic of RST_1 maintained
No
Check the parts and patterns in the path.
Is the clock signal output while the voltage at SPIDS_1 is "L"?
No
Check the parts and patterns in the path.
at "H"? (Does it fall to become "L" periodically?)
No
It is likely a boot error. (It is very difficult to diagnose which peripheral part of the DSP is in failure.)
t
Yes CN351 (Pin 19) MOSI

C
Yes R102 REQ_1
Is the clock signal output while the voltage at SPIDS_1 is "L"?
No
Check the output from the DIGITAL MOTHER Assy.
Does the logic become "H" for a moment when the input stream is changed?
u
No The 1st DSP is in failure. Replace it.
Yes R126
o
Yes CN351 (Pin 21)
Is the clock signal output while the voltage at SPIDS_1 is "L"?
No
Check the parts and patterns in the path.
D
Does the logic become "H" for a moment when the input stream is changed?
v
No Check the parts and patterns in the path.
Yes R125 MISO
p
Yes CN351 (Pin 17) SPIDS_1
Is the clock signal output while the voltage at SPIDS_1 is "L"?
No The 1st DSP is in failure. Replace it.
Does the logic become "L" for a moment when the input stream is changed?
w
No Check the output from the DIGITAL MOTHER Assy.
Yes
CN351 (Pin 18)

E
Yes R123
Is the clock signal output while the voltage at SPIDS_1 is "L"? Yes No Check the parts and patterns in the path.
No
Check the parts and patterns in the path.
Does the logic become "L" for a moment when the input stream is changed?
It is very difficult to diagnose which part is in failure.
