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!!!!
If anyone has a users manual... Please email me. need one. $ [email protected]

Explanation of the Auto Sensor Cooking process 1. During the first 10 second period there is no microwave activity. When calculating the T2 time by using the formula below make sure this 10 seconds is subtracted from the T1 time. In other words, T1 time starts at the end of the 10 second period. 2. T1 time The total amount of time it takes themicrowave oven to switch to T2 time after the 10second period. 3. T2 time When the steam escapes from the cooking container placed in the oven, the steam sensor detects it and the microprocessor calculates the balance of cooking time. This T2 time is then shown in the display and begins counting down. Balance of cooking time (T2 time) The balance of cooking time which is called T2time, can be calculated by the following formula. T2 time (in sec.) = T1 time X K factor NOTE: Remember, the T1 time starts after the 10 second period. The coefficient K is programmed into the microprocessor memory and they are listed in the following tables along with the P1 and P2 powers. NOTE: When "More" or "Less" pad is selected, the K factor varies resulting in T2 time to be increased or decreased. Example of calculating the T2 time Example 1: If the T1 time is measured to be 2 minutes and 40 seconds after the 10 second period, and the Auto program selected is Oatmeal: T2 = T1 � K = 2 min. and 40 sec. � 0.1 = 160sec. � 0.1 = 16 sec.

Sensor reheat (Only for sensor models)
Auto Sensor Reheat is a quick and easy way to reheat refrigerated and room temperature foods. Simply press the reheat pad. There is no need to select power level and cooking time. NOTE: The Auto Sensor Reheat process is same as Auto Sensor Cooking process.
Category Sensor Reheat P1 Power HIGH P2 Power MEDIUM K Factor Standard 0.3

Steam sensor and digital programmer circuit (Only for sensor models)
In order to determine if the steam sensor function of the digital programmer circuit is working, do the following test. 1. Place a water load (150 cc) in the oven. 2. Tap Sensor Reheat pad. 3. Tap Start pad. 4. Steam Sensor detects steam about 1.5 to 4 minutes after the Start pad is tapped. 5. T1 time cooking automatically switches to remaining time for cooking (T2). 6. The remaining cooking time (T2) appears in display window. If the following cooking time appears, Steam Sensor function is normal.
T1 TIME 1 Min. 30 Sec. ~ 4 Min. T2 TIME (Remainingcooking time) 27 Sec. ~ 1Min.12 Sec.

Thermistor
The thermistor which fixed on magnetron detects magnetron temperature and make power down when the temperature becomes abnormal high. A normal thermistor´s resistance values for temperature ranges between 75-85 degree F is from 37k� to 57k�.
