It's a good manual, this one it's a scan from the original factory service manual, great quality 100% readeable. definetely it worths what I paid for.
 ;
A good manual! fast service and good qualityi for pdf document.
thanks!

Very helpful and complete manual. Maybe only one negative is schematics have sometimes unreadable name of the parts. But it's not a big problem.

Excellent high quality schematics brought my old Heidelberg back to life. Fast download at a reasonable price. Thanks.

This document is just what I was looking for, it´s very useful, it contains adjustment procedures for the final stage of the power amp and also
has a complete wiring diagram and description of the main semiconductors used in the design.
1. Video Controller Unit & Display Data Conversion Unit The video controller unit receives the video signals inputted through the tuner, AV port (VIDEO1, VIDEO2), and converts them into an ITU656 signal through the microcomputer (VCTI) combined with the video decoder that integrates various functions in one chip. Either the analog RGB(FLI2300) signal or PC RGB signal is selected by the switching IC and inputted to a scaler (GM2221), which is sent to the LCD module after being modified to an LVDS signal through the integrated LVDS IC. VCTi is the main microprocessor that handles video signal processing and sound signal processing. It also manages the RF signals received from the tuner. The scaler can control timing to fit into the LCD panel, and can also control the size and position of the input signal. 2. Power Supply Unit The power supply unit provides 5V, 15V and 33V DC power to the Mainboard. The 33V is directly used for the tuner. 15V power is directly used by the sound amplifier IC and is also used to generate 5V and 3.3V power through the Step-Down DC/DC Converter. 5V power is converted to 3.3V and 1.8V power through the regulator, which in turn supplies electrical power for ICs such as VCTI and scaler.
