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!

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.
KV-32HS500/32HV600/34DRC500/34XBR800/36HS500/ 36XBR800/38DRC500/40XBR800/42DRC800
+B overcurrent (OCP) Occurs when excessive current �ows through R5013. The increase in voltage across R5013 causes the output of Q5004 to go high, and this high signal goes to the micro. +B overvoltage (OVP) IC6505 detects +B OVP condition and turns on Q6522. This sends a high signal to the micro and also shuts down the AC relay. V-STOP Occurs when an absence of the vertical de�ection pulse is detected by pin 24 of IC2801 (B Board). Power supply will shut down when waveform interval exceeds 2 seconds. White Balance Failure If the RGB levels* do not balance within 2 seconds after the power is turned on, this error will be detected by IC2801. TV will stay on, but there will be no picture. *(Refers to the RGB levels of the AKB detection Ref pulse that detects 1K). Low B OCP/OVP Occurs when set 5V is out. Horizontal De�ection Stopped Occurs when either: 1) a +B overcurrent is detected (IC5007), or 2) overheating is detected (Thermistor TH5002).
