Finally, i found one website, where i can download this service manual , and fix my hifi. The service manual is very good, and easy to download and to print.
 ;
Complete and very useful. Could have benefited from a little higher resolution on the schematic and layout diagrams for improved legibility.
 ;
Great Service Manual, Very Complete, as advertised, Perfect, Thanks!
 ;
Good quality service manual.It has helped me to fix my FV1800,particularly for replacing the dial cord.The scheme is on A3 format and very readable.Thank.Olivier.

This manual is complete and very readable.It was a great help for my two ICF5800L.The first one had the dial cord broken,and without the service manual it is impossible to replace it.Thank.Olivier.
HCD-DX50/RG80
Note : Clear RF signal waveform means that the shape � � � can be clearly distinguished at the center of the waveform.
Adjustment Location: [BD BOARD] (Conductor Side)
RF signal waveform VOLT/DIV : 200mV TIME/DIV : 500ns
level : 0.65 ±0.15Vp-p (RFDC) 1.1 ±0.4Vp-p (RFAC)

Procedure : 1. Connect an oscilloscope to TP (TEO) and TP (DVC). 2. Turn Power switch on. 3. Load a disc (LUV-P01) and playback the number nine track. 4. Press the gG button. (Becomes the 1 track jump mode.) 5. Confirm that the level B and A (DC voltage) on the oscilloscope waveform.
1 track jump waveform center of waveform B A (DC voltage) DVC level=1.0 ±0.5Vp-p symmetry

6. Adjust RV101 on the BD board so that the center of waveform becomes the same voltage of DVC. (i.e. A=0V)
