I was having a hard time finding the problem with this Mackie 1604 unit. I didn't have a schematic. Went looking on the web and found your site and the price was more then reasonable. Ordered it and within the hour had the manual and within 15 minutes had the unit fixed. Best $4.99 I ever spent. Thank you.

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!

4-2-1 HIGH VOLTAGE
Signal: 1024 x 768 (68 kHz/85 Hz) Display image: Don�t care Contrast: Minimum Brightness: Minimum Limit: 26.0 kV ± 0.3 kV Measure the high voltage level at the anode cap. High voltage should be within the limit as above.
4-2-2 CENTER RASTER
Adjust SW401 so that the back raster comes to the center when you apply basic mode for 17�.
4-2-3 Centering
Centering means to position the center point of the display in the middle of the display area. Horizontal size and position and vertical size and position control the centering of the display. Adjust the horizontal size and vertical size to their optimal settings: 312 mm (H) x 234 mm (V). Adjust the horizontal position and vertical position to � 5.0 mm of the center point of the screen. |A-B| � 5.0 mm.
C
Use control bar after selecting �V-SIZE� in left menu to adjust the vertical size of the display pattern to 234 mm.(Tolerance: ± 4 mm.) 4-2-3 (c) HORIZONTAL POSITION ADJUSTMENT CONDITIONS Scanning frequency: Display image:
68 kHz/85 Hz Crosshatch pattern
Use control bar after selecting �H-POSITION� in left menu to center the horizontal image on the raster. 4-2-3 (d) VERTICAL POSITION ADJUSTMENT CONDITIONS Scanning frequency: Display image: 68 kHz/85 Hz Crosshatch pattern

4-2-4 Linearity
Linearity affects the symmetry of images as they appear on the screen. Unless each row or column of blocks in a crosshatch pattern is of equal size, or within the tolerances shown in Tables 4-2 and 4-3, an image appears distorted, elongated or squashed. Table 4-1. Standard Modes Linearity: 1024x768/85Hz
Standard Modes Linearity Difference between Each block (8 %) adjacent blocks (4 %) 4:3 Horizontal: 20.9~23.1 Horizontal: Less than 0.88 mm Vertical : 20.9~23.1 Vertical : Less than 0.88 mm
Click Standard Dump on the right Menu in the general field. Use control bar after selecting size B+ in the left Menu to adjust the horizontal size of the display, Pattern to 312mm(Tolerance : ±4mm.)
