This service manual is a good copy of the original, complete and fully readable. It is really useful to repair my Tv set following its clear instructions.

Excellent quality. Easy process to download. No issues or problems at all - was exactly what I was looking for and needed. Great service.

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!

the manual is great and especially hard to find... thanks for the great service and having a hard to find manuel_
Fast Blanking 75R input and output impedance. This control voltage allows devices to over-ride the composite video input with RGB inputs, for example when inserting closed caption text. It is called fast because this can be done at the same speeds as other video signals, which is why it requires the same 75R impedances. 0 to 0.4V: TV is driven by the composite video input signal (pin 19). Left unconnected, it is pulled to 0V by its 75R termination. 1V to 3V: the TV is driven by the signals Red, Green, Blue and composite sync. The latter is sent to the TV on pin 19. This signal is useful when using a TV to display the RGB output of devices such as home computers with TVcompatible frame rates. Tying the signal to 5V via 100R forms a potential divider with the 75R termination, holding the signal at around 2V. Alternatively, if a TTL level (0 to 5V) negative sync pulse is available, this will be high during the display periods, so this can drive the blanking signal via a suitable resistor. Control Voltage 0 to 2V = TV, Normal. 5 to 8V = TV wide screen 9.5 to 12V = AV mode
