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.

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 :)
CUT OFF, BKGD, SUB-CONT ADJUSTMENT
No. Adjustment point 3 MAX BEAM R1759 Adjustment Condition / Procedure 1. Receive the Monoscope pattern signal with standard mode. 2. Make the image normal with the remote controller. 3. Connect the beam ammeter between TP1601 and TP1602. Ammeter full scale: 3mA range Connect the TP1602 to the - side of the ammeter. Connect the TP1601 to the + side of the ammeter. 4. Adjust the beam current to 1.6mA ± 50µA with R1759 (sub-contrast VR). Note: Apply the adjustment after aging with the beam current 1,500 ± 50µA or more for 30 min or more. (On the white or green monocolour screen.) Waveform or others

(E-2) : Crosshatch (50Hz) (E-5) : Monoscope (50Hz) Adjust the overscan to 8.5 ± 0.5% (Monoscope) (E-5) V-LINEARITY 50 Adjust the linearity to the best. (E-2) V-S CORR~ Already preset (**). (Adjust this unless the linearity is achieved.) (E-2) V-CENT50 Align the center of the screen to the geometric center of CRT. (E-5) H-CENT50 Align the center of the screen to the geometric center of CRT. (E-5) H-SIZE50 Adjust the overscan to 8.5 ± 0.5% (E-5) E/W PARABOLA50 Adjust the end of the line of the crosshatch to be (SIDE-PIN) straight. (E-2) EW-CORNER50 Adjust the end of the line of the crosshatch to be (SUB-SIDEPIN) straight. (E-2) TRAPEZIUM (50) Already preset. (Adjust if the quality is specially poor.) (E-2) OTHER On the items of V-AMPLITUDE60, V-LINEARITY60, V-S CORRECTION60, V-PHASE60, H-PHASE60, H-SIZE60, E/WPARABOLA60, E/W-PARABOLA60 and TRAPEZIUM (60), the compensation data is automatically input if the 50Hz mode adjustment is done.

SUBBRIGHTNESS ADJUSMENT (I2C BUS CONTROL) (RF SIGNAL)
1. Receive the window pattern signal with AV input. 2. Make the image normal with the remote controller. 3. Select the sub-bright adjustment mode with the remote controller, and adjust the right dark white area of the window pattern to 2.7 ± 0.3cd.
* Receive the crosshatch pattern signal or equivalent signal. 1. Make the image normal with the remote controller. 2. Adjust the 3rd (1 thru 5 from the left) black of the window pattern to sink. 2 FOCUS ADJUSTMENT 1. Receive the Monoscope pattern signal. 2. With the remote controller, make the image normal. 3. Adjust the focus VR to make the vertical line of "5" in "E-5" display upper left part of screen as fine as possible.
However, if it is largely deviated when it is checked in the 60Hz mode, readjust it in the 60Hz mode.
