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 :)

Display RST MASK 09 (red 2). / [MKS S59] Note: Disregard the discharge that may appear during voltage-change setting.
Set VOL OFFSET to the setting value 240. / [VOF 240] Gradually decrease the VOL OFFSET value until disappear the discharge (dead cell).

� This setting becomes VOL OFFSET_max1.
VOL OFFSET_max1
Note: Make a note of this VOL OFFSET_max1 value.

No
Replacement of abnormal circuits or re-replacement of the panel required
Yes Display RST MASK 10 (green 2). / [MKS S60]
Set VOL OFFSET to the setting value 240. / [VOF 240]
C
� This setting becomes Gradually decrease the VOL OFFSET value until disappear the discharge (dead cell). VOL OFFSET_max2.
VOL OFFSET_max2
Note: Make a note of this VOL OFFSET_max2 value.
VOL OFFSET_max2
107?
No
Replacement of abnormal circuits or re-replacement of the panel required VOL OFFSET_max
Yes Choose the lower value between VOL_OFFSET_max1 and VOL_OFFSET_max2, and set it as VOL_OFFSET_max.

[From the Recovery flowchart (1-2)]
Is the VOL OFFSET_max value minus the VOL OFFSET_min value greater than 96? Yes
E
No
Replacement of abnormal circuits or re-replacement of the panel required
Are the VOL OFFSET_max value 165 or greater and the VOL OFFSET_min value 069 or less? Yes Set VOL OFFSET to the setting value 117. / [VOF 117]
No
VOL OFFSET_max
165?
No
Yes Set VOL OFFSET to the setting value VOL OFFSET_max minus 48. Set VOL OFFSET to the setting value VOL OFFSET_min plus 48.
F
Determine the current VOL OFFSET setting value as the final value.
