Exactly as described, a Service Manual complete with the schematics and PCB layout delivered in a timely manner. Many thanks for the great service.

some of the writing is a bit blur but the part in the schmatic was great and i have fixed the machine thanks

Well.. I'd searched for this manual and although I found many copies online I was pleased to find your website with a well balanced pricing system and easy to search and follow links. That together with the very quick response time was just what I was looking for.. being a very impatient tech.. ;-) I had the service manual in front of me within a short time.
Bookmarked.. and you can bet I will always come here first for my service & user manuals..
best regards

The service manual when downloaded and printed out was clear and easy to read. I would have liked to have been able to enlarge some details, but this was not possible as the file permissions did not allow this. The service was very good. The time taken from placing my order to downloading the document was only a few minutes.
NOTES: 1. Since the G light is very important for picture quality and performance, pay special attention in its adjustment. 2. Be careful not to touch the lens with your fingers when adjusting. (5) In case of R lens. Set the position where the chromatic aberration changes from red to crimson. As shown below, observe the vertical bright line and adjust lens focus where the crimson or red chromatic aberration slightly appears inside and crimson or red outside (reference value : 1~3mm) at the point specified in table below. Change the signal and fineadjust in the same way as the G lens. L

Adjustment Procedure (7) After all colors have been adjusted, display all colors with the cross-hatch pattern signal and compare the focus (optical focus) performance with the limit sample set. (8) Then, select the circle pattern signal and compare the focus (optical focus) performance of each color and all colors together with the limit sample set. (9) If the focus performance is worse than the limit sample set, re-adjust step (1) to (6).

2.5 STATIC FOCUS ADJUSTMENT
Adjustment preparation (1) LENS FOCUS adjustment should be finished. (2) Contrast : MAX Brightness : Center. (3) Receive the circle pattern signal. (4) Apply covers to the lens of the colors you are not adjusting and project only one color on the screen. Adjustment procedure (1) Red and blue static focus adjustment. Adjust the static focus VR on Focus pack (UFPK) so that the center of circle pattern is the most clear. Check that the focus does not get conspicuously worse at the edges of the circle pattern signal or cross-hatch signal. (2) Green static focus adjustment. Adjust the static focus VR on Focus pack (UFPK) (for green) so that the center of circle pattern is the most clear. Check that the focus does not get conspicuously worse at the checking point, the periphery of circle pattern cross-hatch signal. NOTE: Checking point for the periphery of picture.

(6) In case of B lens. Set the position where the chromatic aberration changes from purple to green. As shown below, observe the vertical bright line and adjust lens focus where the purple or green chromatic aberration slightly appears inside and purple or green outside (reference value : 1~3mm) at the point specified in table below. Change the signal and fineadjust in the same way as the G lens. L
