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 :)

I was very pleased with the service provided and was surprised at how good the quality was of the manual. I thought it may be a third generation copy or so, but it is as good as the websites that charge 3 times this much. I repair some electronics for family and friends without charge, so this is perfect for me. Thank you very much.

MONITOR SECTION
Voltage Adjustment Setting : DIMMER selector (S701) : HIGH BRIGHT dial (RV702) : Max. (light) VOL dial (RV301) : Max. Procedure : 1. Input the color bar (chroma off) signal from NTSC color bar generator and display on the monitor screen. 2. Connect the digital voltmeter to CL66 on the monitor main board. 3. Adjust RV401 (+5V) so that the digital voltmeter reads 5±0.1 V DC. 4. Connect the digital voltmeter to CL86 on the monitor main board. 5. Adjust RV601 (+9V) so that the digital voltmeter reads 8.5±0.1 V DC. Connection points : Monitor main board Refer to page 5. Alignment points : Monitor main board Refer to page 5. RGB Adjustment Procedure : 1. Input the color bar (chroma off) signal from NTSC color bar generator and display on the monitor screen. 2. Connect the digital voltmeter to CL151 on the monitor main board. 3. Adjust RV213 (OFFSET) so that the digital voltmeter reads 2.3±0.1 V DC. 4. Connect the oscilloscope to CL42 on the monitor main board. 5. Adjust RV212 (COM CUT) so that the lower black level is 6.2±0.05 V DC. 6. Adjust RV208 (COM DRIVE) so that the upper 100% white level is 9.2±0.05 V DC. 7. Repeat steps 5 & 6 until the items in the standards are satisfied. 8. Connect the oscilloscope to CL41 of the monitor main board. 9. Adjust RV207 (R DRIVE) so that the lower black level is 6.2±0.05 V DC. 10. Adjust RV202 (R CUT) so that the upper 100% white level is 9.2±0.05 V DC. 11. Repeat steps 9 & 10 until the items in the standards are satisfied. 12. Connect the oscilloscope to CL43 of the monitor main board. 13. Adjust RV209 (B DRIVE) so that the upper 100% white level is 6.1±0.05 V DC. 14. Adjust RV204 (B CUT) so that the upper 100% white level is 9.1±0.05 V DC. 15. Repeat steps 13 & 14 until the items in the standards are satisfied.
