The service was quick and simple, finding the service manual easy and it appears to be the original with colour schematics. It contained the info I was after and so sorted the problem.
I have copied it to CD and attached the envelope to the inside back cover of the owners manual. Good manual and excelent service. Robin Wood, Wood Electronics, New Zealand.

Nice to have the service manual for the Sony DCR-TRV345E now. The document is of excellent quality.

MACKIE HR824 26 pages English-only Service Manual contains:
1) HR824 technical overview with the description of front and rear panel switches.
2) HR824 specs
3) Block Diagram
4) Wiring Diagram
5) Packaging management
6) Spare part & final assembly list (for PCB rev A and B) + exploded view
7) Test Procedures (where, how to measure voltage...) including Test Point diagram on the PCB.
8) IC and Transistor charts.
Excellent guide: very clear, good scan quality enabling us to print readable diagram :-)
Note:
Mackie HR824 make extensive use of surface mount devices (SMD). Service on the HR824 must
only be undertaken by experienced service technicians with the right tools, experience and patience to perform surface mount rework when needed.

This Service manual is very well scanned and its clean to read, no any anti-theft words that un-english could understand. I got my CCD600 working with this manual and it´s clear shematics :)

+ �
Checking Location: � BD BOARD (Conductor Side) �
Procedure: 1. Set the test disc (PATD-012). Disc chucking operation is complete, then press the [POWER] button to turn the power off. 2. Connect an oscilloscpe to test point TP (TE1) and TP (VC) on the BD board. 3. Connect between test point TP (ADJ) on the MAIN board and GND by lead wire. 4. Press the [POWER] button to turn the power on and enter the ADJ mode, then playback the number two track automatically. 5. Press the [TIME] button. (The tracking servo and the sledding 6. servo are turned OFF) Check the level B of the oscilliscope waveform and the A (DC voltage) of the center of the Traverse waveform. Confirm the following : A/B x 100 = less than ± 22%
Traverse Waveform
Center of the waveform B 0V A (DC voltage) level: 1.15 ± 0.5 Vp-p

TP (RFDC)
TP (RFAC)
7.
Press the [TIME] button. (The tracking servo and sledding servo are turned ON) Confirm the C (DC voltage) is almost equal to the A (DC voltage) is step 6.
