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!!!!

INTERMEZZO 4.1t
Service Bulletin
Service Bulletin INF2003-03 - June 2003 To: All Infinity Service Centers Warranty labor rate: MAJOR repair
Model: Intermezzo 4.1t Subject: Distortion at Low Volume Levels In the event you receive an Intermezzo 4.1t with the complaint �there is distortion at low volume levels, particularly when higher frequencies are present�, perform the following procedure: Synopsis: Remove three components and re-wire them in a similar circuit on the opposite side of the Feature PCB. 1) Remove the woofer grille; extract the (6) rubber grille retainers; this can be accomplished by carefully pulling them out of their cavities with long-nosed pliers or similar tool. 2) Remove the (6) Phillips screws from the woofer trim ring. 3) Remove the trim ring with the woofer attached; unplug the two wire leads. 4) Remove the (6) Phillips screws at the rear of the enclosure, and push the amplifier assembly into the enclosure. 5) Unplug the three connectors from the amplifier; remove the amplifier from the woofer opening. 6) Remove the 4 screws holding the front faceplate w/ controls and Feature PCB to the plastic enclosure; pull the assembly out as far as the attached wires will allow. If the rectangular gasket bordering the enclosure is damaged during this procedure, order Infinity part# MM0080. 7) Unplug all wire connectors on the PCB except the AC power wires, which can remain attached. 8) Remove the 2 screws holding the HP push button switch assembly to the faceplate; remove the assembly and plastic spacers. 9) Locate and remove resistors R153 (2.2K�), R154 (5.6M�) and diode D110 (1N4148). 10) Resolder the three components together on the rear of the PCB, following the examples below: �Circuit Equivalent�, and supplied image on Page 2. Observe polarity for D110. Solder an insulated 16 - 20 gauge (0.5 to 1.0 mm2) jumper wire to the cluster of parts to complete the connection. Cut the PCB traces in the indicated areas. Add a dab of silicon sealer or equivalent adhesive to hold the components in place on the PCB.
