Very good conversation, Pretty fast Service, wood do it again,
Have paid by Paypal, so i got the Service Manual online after 15 Min.
Very helpfully.
Greeting from Germany,
Hans

Good-quality scans. Detailed description. I hope I can repair the machine.

High-quality scanning. Detailed description. Recommend for all technician. A+++

This is a good quality scan of the original Service Manual from Nordmende, Germany. Contains the circuit diagram, PCB layout, adjust/tune instructions as well. It is NOT in English but in GERMAN language! That was quite right for my german friend from the lower east side in Berlin.

Received via e-mail this PDF manual is worth the money. This is a quality scan of a manual in excellent condition and is just as good as having the original manual in hand. I have later seen the original manual and it was printed in colour, but this particular manual is black & white but scan resolution is high end quality! All drawings and pictures are presented in great detail. So, nearly perfect score in my opinion.
If you own the turntable you also should own the manual!

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.
