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.

Exactly what was needed to assess the product - excellent value and great service

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 :)
(5) Lighting in green, and then in red (Alarm of power voltage error) Unlike [lighting in red] in the STANDBY mode, [lighting in green] continues for about 30 seconds without any output of images and audio signals. Since then, the mode turns into [lighting in red]. (Caution) How to reset the alarming condition The alarming condition can be reset when an OFF�ON setting is repeated twice for the main power supply in the state that the LED is lit in red. The interval between the first and second settings is not particularly specified.
Lighting in red
Make an OFF � ON setting twice for the main power supply in order to reset the alarming condition. Is the LED lit in red after it has been lit in green for about 30 seconds? YES When the main power supply is turned on in the state that the AD, PD, and PH connectors are disconnected, are there the Vs (170Vdc) and Vd (60Vdc) outputs at Pins 6-7to Pins 9-0 of the PD connector and a 5Vdc output at Pins 1-2 of the PH connector? In this case, is the LED not turned in red after it has been lit in green for about 30 seconds? At that time, however, no images are generated. NO When the main power supply is turned on in the state that the PA and PV connectors are disconnected from one after another, is there a 12Vdc output at Pins 1-3 of the PA connector or the 12Vdc and 6Vdc outputs at Pins 1 and 3-4 of the PV connector? In this case, is the LED not turned in red after it has been lit in green for about 30 seconds? NO Is there an output of 3.3Vdc available at Pins 1~3 and 2.5Vdc at Pins 7~9 in the state that the PA and PV connectors are returned to the former state, the main power is turned ON, and the PN connector is disconnected? In this case, however, this check must be finished in 30 seconds. Otherwise, there will be power tripping on account of an alarm. NO
Normal
Refer to P7-1 "HOW TO DIAGNOSE THE PDP MODULE". YES The PDP is fault. (Caution) The voltage values of Vd and Vs can differ according to the PDP. The method of checking these voltage values is obtainable from [2. Adjustment of the power unit] in the method of adjustment.
YES
The MAIN PWB or the AUDIO PWB is fault.
NO
The Power unit or the PN connector is fault.
YES The MAIN PWB is fault.
