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!!!!

In case of warming up of more than 2 hours under a condition that the large anode current is running through the projection tube so that for example the all-white pattern appears, adjust to obtain the sharpest focus while observing the whole screen like in the RED case. 11. Press a button on the remote controller in order to display the internally-generated black cross-hatch. (See TEST SIGNAL SELECTION on page 11.)
Note: Keep in mind that only the BLUE electric focus is adjusted with the black cross-hatch. 20. Check the BLUE focus of the whole screen and if necessary repeat steps 17 and 19. 21. Fix the BLUE lens by tightening its fixing screws.
TILT ADJUSTMENT Rotate R, G, B deflection yoke so that picture becomes horizon, then fasten screw. CENTERING ADJUSTMENT 1. Stretch a thread between two center of screen edge (top and bottom, left and right).
12. Use the focus VR of �G� of the focus pack in order to adjust the electric focus in the middle section of the screen to its sharpest level. Note: Normally the most clearly visible point of the scanning line is the sharpest point of the Green focus, however as the characteristics vary depending on the projection tube, the sharpest focus points of the vertical and horizontal lines may not match each other, thus when you turn the focus VR, if the picture tends to be tremendously unstable (rolls horizontally or vertically), adjust the balance of the vertical and horizontal lines to its best position. 13. Check the GREEN focus of the whole screen and if necessary repeat steps 10 and 11. 14. Fix the GREEN lens by tightening up its fixing screws. 15. Expose only BLUE by covering the RED and GREEN lenses with caps. 16. Press a button on the remote controller in order to display the internally-generated cross-hatch (See TEST SIGNAL SELECTION on page 11.) 17. Loosen the BLUE lens fixing screws (refer to Fig. a), and adjust the BLUE lens focus while observing the middle and peripheral screen sections. 18. Press a button on the remote controller in order to display the internally-generated black cross-hatch (See TEST SIGNAL SELECTION on page 11.) 19. Use the focus VR of �B� of the focus pack in order to adjust the focus in the middle section of the screen to its sharpest level. (The point of the Blue focus becomes sharpest when the brightness level of BLUE is lowest, the cross-hatch is clearly visible.) 2. 3. Select the adjustment mode. (See page 10.) Press a button on the Remote Control to display the black cross-hatch.
4. 5. 6. 7. 8.
Adjust G centering magnet so that the cross-hatch pattern center comes to screen center. Perform HEIGHT adjustment . (See page 14.) Perform WIDTH adjustment. (See page 14.) Check whole quality of green line. Adjust R, B centering magnet so that the cross-hatch pattern center comes to screen center.
