Very quick response. Very good and accurate print quality of the scanned document.
 ;
The service manual was very usable and clear enough to see the individual values of all of the components (unlike some of the service manuals I have gotten in the past from web sites similar to this one). The price was right and the information was greatly appreciated. It helped me with an otherwise very difficult repair. It was much needed and appreciated. A faster turn around on my order would be nice, but I understand the constraints on your staff's time. Thank you for your service.

Excellent manual. Helped me out with disassembling and troubleshooting my projector.

Note on Printed Wiring Board: � X : parts extracted from the component side. � Y : parts extracted from the conductor side. � : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.) Caution: Pattern face side: (Side B) Parts face side: (Side A) Parts on the pattern face side seen from the pattern face are indicated. Parts on the parts face side seen from the parts face are indicated.
� % : indicates tolerance. � C : panel designation. � A : B+ Line. � Power voltage is dc 4.5V and fed with regulated dc power supply from extermal power voltage jack. � Voltages and waveforms are dc with respect to ground under nosignal conditions. no mark : POWER ON � Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. � Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. � Circled numbers refer to waveforms.
� Main boards is six-layer pritnted board. However, the patterns of layer 2 to 5 have not been included in this diagrams.
� IC1 (microcomputer) and IC7 (flash RAM) on Main board cannot be replaced individually. Replace it with Main board assembly for service.
� IC1 (microcomputer) and IC7 (flash RAM) on Main board cannot be replaced individually. Replace it with Main board assembly for service. * The voltage and waveform of CSP (chip size package) cannot be measured, because its lead layout is different form that of conventional IC.
