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!!!!

1-3. Adjustment of FM_ANT&RF Coil
Voltage Check Point : S-METER-Check Land (PWB Side B, around W572) Adjustment Coil : ANT Coil = L505 RF Coil = L506 Setting of Signal Generator : Refer to the following tables.
TYPE E/M K J MODE FM FM FM freq. 87.5MHz 87.9MHz 76.0MHz Mod. OFF OFF OFF ANT Input 5 or 11dBuEMF 5 or 11dBuEMF 5 or 11dBuEMF Fig (A),(C) (A),(C) (A),(C)
1-1. VCO Coil Adjustment - Adjustment of Tunning Voltage
: Vt-Check Land (PWB Side B, around D506) Adjustment Coil : L507 (VCO Coil) The adjustment method : VCO coil is turned and adjusted according to the following tables.
TYPE E/M K J Mode AM AM FM freq. 1611kHz 1700kHz 90.0MHz Voltage 5.5 ± 0.1(V) 5.8 ± 0.1(V) 5.6 ± 0.1(V) Fig (C) (C) (C)
Voltage Check Point
qThe appearance and the coil with which S-METER DC voltage serves as the maximum are turned and adjusted in the above-mentioned SG input. wBy the above-mentioned adjustment method, same adjustment is performed to both sides (ANT & RF Coil).
M : AM Adjustment For Your Information : The frequency of SET is only set up by Pre-Set-Key in case this adjustment
1-4. Adjustment of STEREO (adjustment of 456k-VCO)
Adjust in TEST MODE � How to enter the test mode While pressing on [FM] and [PRESET 6] keys, reset the unit. � Adjustment method Complete on condition that show �ALL OFF� when pressing on [PRESET 1] and [PRESET 6] keys. (Writing adjustment valve to the EEPROM.) Effect of adjustment is in cofirmation of adjustment status at [PRESET 4] key. � Display of [PRESET 4] Adjustment �OK� : 14seg model �E2P OK� 7seg model �EPO� Adjustment �NG� : 14seg model �E2P ERR� 7seg model �EPE� � Releasing the test mode Reset mode only. ACC off, Power off, Power down and Remove the panel mode is not releasing.
1-2. Adjustment of 1st & 2nd-MIX Coil
Voltage Check Point : S-METER-Check Land (PWB Side B, around W572) Adjustment Coil : 1st IFT = L508 / 2nd IFT = L509 Setting of Signal Generator : Refer to the following tables
TYPE K E,M,J MODE AM AM freq. 1000kHz 999kHz Mod. OFF OFF ANT Input 35dBuEMF 35dBuEMF Fig (B),(C) (B),(C)
q The appearance and the coil with which S-METER DC voltage serves as the maximum are turned and adjusted in the above-mentioned SG input. w By the above-mentioned adjustment method, same adjustment is performed to both sides (1st & 2nd MIX Coil).
