Even if the PDF is a scan, I can read the information I need.
The price is affordable and the service (mail sending) is very fast.
Thanks ! Regards. William (Fan of Kenwood)

Very good quality original datasheet!I like this amazing website!!!!!!
 ;
Excellent just what I needed to replace the electrolytic caps and make this old gem a beauty again. Was as scan of the original photocopied service manual.
;
It was helpful to get schematic with waveforms in important points and lot of service information. Manual is good quality, fast delivered. Of course it is hardcopy of paper one with all its disadvantages.

I want to give you a real heads-up for your desire to enable such people as I to acquire the information I need to maintain the older types of equipment such as this Akai HXA351W. You do a swell job with all the processes you have to perform so I can have a legible, thus usable
document which does not send me crazy trying to figure out the blurry text of a bad copy.
Very well done, Thomas.
6. Feed a white raster signal through RGB connectors and turn on the power of the projector. (If a signal generator which provides a white raster signal is not available, turn on the power without connecting the LCD panel.) 7. If all three LCD panels need to be replaced, refer to the �Green LCD adjustment�. 8. Adjust the focus ring and the raster focus of the LCD which has not been replaced. If the green LCD is not replaced, adjust the green raster. If the green LCD is replaced, adjust the red raster, and if the red LCD is replaced, adjust the blue raster. 9. Atach the wall chart to the wall so the bottom line of the square lines up with the bottom of the raster. Also, center the chart horizontally with the raster. 10. Adjust the zoom ring and make sure the bottom of the raster remains on the bottom line. Return the zoom ring to the maximum wide setting. 11. Hereafter, do not move the setting position and the focus ring.
5. If the focus or raster geometry is changed, when tightening the screws holding the LCD mount, loosen the screws slightly and readjust. 6. Prepare one focus adjustment jig and insert it onto the one hole on top of the LCD plate, and adjust the LCD plate back and forth until the best focus is obtained in considering upper and lower balance of the projection screen. (Refer to Fig. 3-2-7.) 7. If the focus or raster geometry is changed, when tightening the screws holding the LCD mount, loosen the screws slightly and readjust. 8. Input the cross hatch pattern of G signal. 9. Adjust the cross hatch pattern up & down (Refer to Fig. 3-2-8) and left & right (Refer to Fig. 3-2-9) with the three adjusting screws (hex screw driver (1.0 mm) available on the market) until it is aligned with the green cross hatch pattern.
< Red/Blue LCD adjustment > 1. Confirm connection of the LCD panel (if not connected, connect the LCD to the connector of the PC board.) 2. Turn the projector on. 3. Input the cross hatch pattern from RGB connectors. Only input R signal when adjusting the red panel focus, and only input B signal when adjusting the blue panel focus. 4. Prepare two focus adjustment jigs. Insert them onto two holes on bottom of the LCD plate, and adjust the LCD plate back and forth until the best focus is obtained in considering left and right balance of the projection screen. Fig. 3-2-8
Fig. 3-2-9 10. Turn off the power, and remove the FPC section of the LCD from the connector of the drive PC board.
