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.
3.JITTER CHECK 1) While oscilloscope is kept connected in the same test point as in step2. RF WAVEFORM CHECK, connect the output terminal of an oscilloscope to the input terminal of the jitter meter. 2) 3) 4) Set the VOLT range selector of oscilloscope to 500mV range or below. Play back 2nd track of TCD-782.

Check that jitter meter indicates 28.0ns or less.

4. PLAY ABILITY CHECK 1) Play back the 3rd , 8th and 13th track of ATD-001. Check that the noise does not occur sound skipping does not occur.
5.LASER CURRENT CHECK *Do not perform this measurement unless the laser is suspected to be defective. 1) 2) 3) Connect digital multi-meter across the resistor R402(10Ω). Play back the TCD-782 and check the DC voltage value on the digital multi-meter. Calculate the laser current (Iop) by dividing the DC voltage across R402 by the resistor value (R402= 10Ω). Check that the laser current (Iop) is 60mA or less.
