This is a service manual in every sense of the word ( French and German versions of the text are included, as well as English..)
There are explanations of the mechanical and electrical functions, plenty of mechanical drawings, and the needed schematics. The quality of the scanning is excellent - all the component values are clearly legible - and very usefully there are pcb component layouts, so you can find a component on the schematic, and then very quicky pinpoint its physical location on the relevant pcb.
I cannot see how I can give this manual any less than the maximum 5 stars! Great value for money, which will pay for itself immediately. Excellent all round!

I got the manual quickly after the payment was transfered (1 day). The manual was exactly what i needed and the updates via e-mail were great. Thanx!

6.2 Adjustment of DPS ASSY (Video SCR ASSY)
� If deviation of the time axis occurs on the oscilloscope screen, or to move the screen to have a better view, perform fine adjustment using a delay. However do not change the ranges of the vertical and horizontal axes. � When reading the waveform on the oscilloscope screen, read the center of the waveform noise. � If the signal waveform on the oscilloscope is difficult to read, adjust the luminance.

6.2.1 Adjustment of video output pedestal potential
1. Connect the equipment as shown by the dotted lines in Connection Diagram 2. 2. Set the equipment as shown below. a. Oscilloscope 0.1V/div (DC mode) 5µs/div H-SYNC TRG. b. Video SG Staircase signal (1 Vp-p/75�) 3. Set the oscilloscope to the GND mode, and adjust the oscilloscope so that the luminance line is at the center of the oscilloscope. 4. Connect the equipment to the CN3002 (J1002) of the DPS ASSY using a tool as shown by the lines in Connection Diagram 2. 5. Set the unit to the STANDBY mode. The other functions can be set as desired. 6. Set the oscilloscope to the DC mode, and adjust VR1004 (RV1004) in the DPS ASSY so that the pedestal potential of the video waveform satisfies the GND potential set at step 3 (within 0±0.02V).
