If only dashes — are entered in the service position column, trouble diagnosis is possible without disassembling this DVD video camera/recorder.

3)Connect the measurement terminals to the check points, and collate the results with the details of check.

Letters in brackets [ ] that follow the check points show the name and side of circuit board. Example: [MAN-A] shows that the check point exists on side A of MAN-H/MAN circuit board.

Information:

The MAN-H/MAN or AEL-H/AEL circuit board has some check points to which no terminals of test equipment can be directly connected even when this DVD video camera/recorder is set to a service position.

Solder a lead wire of approx. 10 cm to such check points, referring to “Disassembly/reassembly to enable service position” and “circuit board diagrams”. When trouble diagnosis is complete, be sure to remove the lead wire.
