The manual is well organized and is easy to read. The chapters are following normal way to proceed.
This scanned manual is well done in that most all the pages except for one is straight and clear- the way I would do them. One page was upside down but that happens. For the money that is charged on this site you get a pretty good deal. Now with complex repairs, I still prefer to us paper manuals which I have to buy at stereomanuals but the one I got here was much less than the $45 he was charging but this is a larger than normal manual for three different units. I am a picky manual user because I have used original manuals from Sony and Teac.
Very useful service manual, was exactly what i needed.Good quality,reasonable price.Thank you.
Acurate informations inside the SM and I could repair my old Sansui SC-3330 without any problems. Thanks.
I used it to repair a NAD 7030, but unfortunately, the 7045 is different !
But documentation was useful.
Replacing the Lamp
All projector lamps will wear out eventually. If used for long periods of time, the image could become darkened, and the color contrast could be impacted as well. We recommend that you replace your lamps early. If the LAMP indicator turns red, or a message prompts you to replace the lamp when you power up the projector, the lamp needs to be replaced. (See "Related Messages" and "Regarding the Indicator Lamps" for details.)
Turn off the projector, and unplug the power cord. Allow the lamp bulb to cool for at least 45 minutes, and prepare a new lamp (sold separately: DT00511 for CPS317/EPS3170/EPS3170A or / DT00521 for CPX327/EDX3270/EDX3270A)
Insert the new lamp, and tighten the 1 screw firmly to lock it in place
â¢ Also steadily push the opposite side of the screwed side of the lamp into the unit.
After making sure that the projector has cooled adequately, slowly flip over the projector, so that the bottom is facing up
Unscrew the 2 screws, and remove the lamp cover
Replace the lamp cover, and tighten the 2 screws firmly to lock it in place
Unscrew the 1 screw, and slowly pull out the lamp by the handle
â¢ Be careful not to touch the inside of the lamp case.
Slowly turn the projector so that the top is facing up Turn on the projector power, and using the menu, reset the lamp timer
â¢ To reset the lamp timer, from the OPTION menu, select LAMP TIME.
ATTENTION â¢ Make sure that the screws are screwed in firmly. Loose screws could result in damage or injury.
â¢ Do not use with lamp cover removed. â¢ Do not reset the lamp timer without replacing the lamp. Reset the lamp timer always when replacing the lamp. The message functions will not operate properly if the lamp timer is not reset correctly. â¢ When the lamp has been replaced after the message of "CHANGE THE LAMP ...THE POWER WILL TURN OFF AFTER 0 hr." is displayed, or the LAMP indicator is red, complete the following operation within 10 minutes of switching power ON.
â¢ The LAMP indicator is also red when the lamp unit reaches high temperature.
Before replacing the lamp, switch power OFF, wait approximately 20 minutes, and switch power ON again. If the LAMP indicator is still red, replace the lamp.
