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.

Alignments
Align the vertical centre of the picture to the vertical centre of the CRT.This is the first alignment to be performed of the vertical alignments. For an easy alignment set SERV.BLK to ON. Vertical S-correction (VER. SCOR) Align the vertical linearity, meaning that vertical intervals of a grid-pattern must be equal over the entire height. Vertical amplitude (VER. AMPL) Align the picture height so that the complete test pattern is visible. Note that other vertical alignments are not compensated. Vertical shift (VER. SHIFT) Align the vertical centering so that the test pattern is located vertically in the middle. Repeat the 'vertical amplitude' alignment if necessary. Horizontal shift (HOR. SHIFT) Align the horizontal centre of the picture to the horizontal centre of the CRT. Horizontal parallelogram (HOR. PARALLEL) Align straight vertical lines in the top and the bottom; vertical rotation around the centre. East West width (EW. WIDTH) Align the picture width until the complete test pattern is visible. East West Upper Corner (EW. UCORN) Align straight vertical lines in the upper corners of the screen. East West Lower Corner (EW. LCORN) Align straight vertical lines in the lower corners of the screen. East West Trapezium (EW. TRAP) Align straight vertical lines in the middle of the screen. East West parabola (EW. PARA) Align straight vertical lines at the sides of the screen. Horizontal bow (HOR. BOW) Align straight horizontal lines in the top and the bottom; horizontal rotation around the centre.

Figure 2 Initial Set-Up 1. Connect an external video pattern generator (PAL-475.25 MHz) to the aerial input of the TV-set with a crosshatch test pattern. 2. Set SMART PICTURE to NATURAL. 3. Activate the SAM-menu and select GEOMETRY. 4. Set VER.SCOR to value: � �8� for 28� WS picture tubes, � �13� for 25�, 28�, 29�, 32� and 34� 4:3 picture tubes, � �23� for 29� SF picture tubes. 5. Set VER.ZOOM to value: � 25 (for widescreens; set in SUPER WIDE mode to 35).
When a NTSC signal is used on one of the EXTERNAL inputs, the following additional alignments can be performed to correct the picture (descriptions above): 1. Horizontal width 60 Hz (H60. WIDTH) 2. Horizontal parallelogram 60Hz (H60. PARA) 3. Horizontal shift 60 Hz (H60. SHIFT) 4. Vertical amplitude 60 Hz (V60. AMPL) Sound There are no adjustments needed for SOUND. Default values: � � � � � � � NIC-FMAM = 250 2CS-FM = 40 PS-FM = 27 PS-NIC-BGDK = 58 PS-NIC-I = 127 PS-NIC-L = 58 DEVIATION = OFF
�
Alignment Sequence For all sets: 1. 2. 3. 4. 5. 6. 7. 8. 9. Set SERV.BLK to ON Adjust VER.SLOPE Set SERV.BLK to OFF Adjust VER.AMPL and VER.SHIFT Adjust EW.WIDTH and HOR.SHIFT Adjust EW.PARA Adjust EW.UCORN and EW.LCORN Adjust EW.TRAP Adjust HOR.BOW and HOR.PARALLEL
�
For widescreen sets only (go to super wide mode): 1. Set SERV.BLK to ON 2. Adjust VER.SLOPE 3. Set SERV.BLK to OFF 4. Adjust EW.WIDTH and HOR.SHIFT 5. Adjust EW.PARA 6. Adjust EW.UCORN and EW.LCORN 7. Adjust EW.TRAP 8. Adjust HOR.BOW and HOR.PARALLEL
Explanation of terminology � Service blanking (SERV. BLK) Switch the blanking of the lower half of the screen ON/OFF (to be used in combination with the vertical slope alignment). � Vertical slope (VER. SLOPE)
