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.

The service was great and the document was also great. Highly recommend!!!!
If anyone has a users manual... Please email me. need one. $ [email protected]
NOTES In many cases, color misconvergence may be corrected by returning HIT and WID data in main deflection side to initial adjusting values. Following cases will surely require readjustment of convergence. CRT REPLACEMENT When CRT is replaced, main deflection readjustment and color matching are required. Perform following procedures. 1. Replace two CRT�s of blue and red. 2. Perform horizontal adjustment for blue and red yokes on base of green CRT data. Mount yoke and velocity mod. coil alignment, pushing towards CRT without gap. 3. Adjust alignment of blue and red. (Refer Alignment adjustment for details.) 4. Rotating centering magnet, adjust CRT centers of red and blue to CRT center of green. (Picture position adjustment) 5. Adjust HIT and WID data of main deflection, and decide data at the most precise screen comparing to green data. 6. Adjust convergence of each screen picture for color matching. Do not move green one at this time. 7. After convergence adjustment of each screen picture finishes, replace green CRT. For green CRT as well, repeat steps 2 to 5 above on bases of red and blue color matching to adjust convergence. REPLACING CONVERGENCE UNIT When replacing convergence unit, all picture screens require readjustment basically, but the following method allows process be reduced considerably. 1. Replace the memory (Q713) on defective unit with memory on new unit. Mounting the unit on the SET after the above working realizes picture screen before replacement immediately. 2. Mount unit which has combination of old and new memories, on SET and turn it on. Screen shows whole picture looks like straightly shifted towards vertical or horizontal direction. 3. Adjust again centers of green, red and blue with centering magnets. 4. Check each picture screen for slight disparity of color and picture size. If necessary, add some adjustments of main deflection and color matching of convergence.
