Owner-manuals.com is the best Possibility to give vantage HIGH CLASS Elektronic COMPONENTS
a new Life.Thanks alot for your perfekt Service.
;
I am proud of you. In the future, I benefited from your services.
;
I found this manual to be complete in every detail. Besides the schematic it has a complete set of alignment instructions which are easy to understand. It also includes a complete parts list as well as an explanation of how the power supply and safety shutdown circuits operate. Even a schematic of the tuner is included.
 ;
The product was good and just what I needed, however I had moderate difficulty with the down load because the sight would not recognize my pass word. I was finally given a direct link to the manual and that worked.
;
Very quick and easy website to use and fast download of manual, quality of manual is excellent and will be pleased to use this service again in the future, thanks so much!
Note 7: B/W LCD (H002) is driven by microprocessor (IC101) on the Main unit (U002). So either of them may contain a problem. Note 8: As the zoom motor of lens is driven with pulses generated in the gate array (IC501) on the Main unit (U002) and passed through the motor driver (IC404), either one of them or parts used for them will be suspected. Note 9: Focus motor of lens is driven with pulses generated on the gate array (IC501) on the Main unit (U002) and passed through the motor drive (IC403). So, if the focus operation is entirely no good, either one of the circuits or parts used for them will be suspected. If the focus operation is normal but focus is not good, adjustment failure will be suspected. Perform the adjustment again according to the electrical adjustment procedures. Note 10: Light emitting pulses for the strobe are generated in gate array (IC501) on the main unit (U002), and the charging control is carried out by the microprocessor (IC101). So, one of them or parts used for them will be suspected. If light intensity is excessively poor, the adjustment may be upset. Make the adjustment again according to the Electrical adjustment procedure. Note 11: In the CCD unit of Lens block (U004), signals from CCD (IC1) are converted into digital signals by the A/D converter (IC3) and then the signals are fed to the Main unit (U002). The CCD is driven by TG(IC4) and V driver (IC2). In the main unit, the signals are fed to the DSP (IC503) in passing through a gate array (IC501), and displayed on the color LCD through the LCD circuits. If a picture is not displayed on the screen, these circuits will be suspected. The picture is not displayed if the lens aperture is closed, in this case lens aperture drive circuit will be suspected. Pulses generated in a gate array are fed to the motor driver (IC403) and the driver drives the lens aperture. Note 12: Playback picture image read out from the SmartMedia is JPEG-decoded in DSP (IC503) on the Main unit (U002) and displayed on the color LCD (H001) in passing through the LCD circuit. So, these circuits will be suspected. Note 13: CCD (IC1) in the lens block (U004) has variations in the sensitivity and saturation level, so an adjustment has been made at factory shipping. When the lens block and the Main unit (U002) are replaced, perform the adjustment again according to the Electrical Adjustment Procedures. Note 14: CCD (IC1) in the lens block (U004) has pixel defect (white scratch, scratch), color filter variations, etc. So, an adjustment has been carried out at the factory shipping. When the lens block and the Main unit (U002) are replaced, perform the adjustment again according to the Electrical Adjustment Procedures. Note 15: Detections of buttons and mode dials are carried out with DSP (IC503) on the Main unit (U002). As the buttons and mode dials are located on the Main unit, Rear unit (U201), and Switch module (A400), check connections between the unit having the button relating to the failure and the Main unit.
