Manual acquired with good resolution, complete in all its pages, very good policy of the folder where are saved all products purchased.
 ;
Service manual very complete and clear. It was very helpfull for my work.
;
This is the 2nd time I download manuals from this website and I can say it's what I was expecting. It contains schematic, layout (decent quality), short description, parts and dissasembly instructions. I recomend it for anyone who wants to repair/modify this device.

Very useful Service Manual! With it I was able to identify the damaged pots in my old amplifier, purchase the adequate replacements and make myself the repair.
I have again my old amplifier, still a very good one that I will keep for as many years as I can!
Thanks to Owner Manuals!
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.
