Dear Sir,
Document is original service document of sharp. I had a problem with the door contacts. Fuses where blown. With the manual in a few minuts is was clear what the problem was.
Manual was of great help.
With kind regards,
Martie Verhoeven

The scan is clear and well readable with very few weaker spots, usually on black background with white letters, but with enough zoom those spots can be read.
Printout is clear, the manual is complete and has all pages scanned.
I would give 5 stars, except that it is not in color, and the schematic and PCB pages are scanned on multiple pages. The document is locked (except printing) so the pages can not be extracted to compose them together for printing on the large plotter
It is worth the price tag.

let's say first that i do not need to have a credit for my opinion, i am a retired sparkie and i voluteerd to fix an electronic device for a local "Youthgroup",as no diagram was present i checked the "net" and gambled on this site and paying some fee via PayPall, i was gladly surprised that the manual arrived as was stated, GOOD SHOW, and best wishes, John

I had been looking for a Manual for my CS2150 for quite a while -- in fact I had just about given up. I saw this site and decided to download the Manual. When I Received it by Email I was really pleased with what I got, with the result that My Kenwood 'Scope is now 100% repaired and working well. As an AV Serviceman, you need a good 'scope, and thanks to this site, and the Service Manual, I have been able to repair it. The Manual was a copy of the Factory Original and the copy was very clear, especially in the area of the Circuit Schematics, where You really need to be sure of what You are looking at.

I recently purchased a manual for a Samsung DLP tv to help with a trouble shooting problem I was having. Every tv repair shop wanted close to $400.00 for the fix, but after I found Owner-Manuals.com I hit pay dirt. The manual they had for me to purchase and download was a complete service manual for the exact tv I needed. It was complete with wiring diagrams, schematics, and even part numbers. If your the fix it yourself type I highly recommend trying to find any manual here before paying someone else to fix whatever problem your having.

Check points for each error
5.2.1 Spindle start error (1) Defective spindle motor � Are there several ohms resistance between each pin of CN201 "2-3","3-4","2-4"? (The power supply is turned off and measured.) (2) Defective spindle motor driver (IC201) � Has motor drive voltage of a sine wave or a rectangular wave gone out to each terminal(UOUT,VOUT,WOUT) of CN201"2,3,4" and IC201"19,18,17"? � Is FG pulse output from the terminal of IC201"41"(FG) according to the rotation of the motor? (3) Has the control signal come from the microcomputer? � Is it "H" while the terminal of IC201"48"(MUTE1) is operating? � Is the control signal input to the terminal of IC201"25"(SPDRV)? � Is the SVREF voltage input to the terminal of IC201"26"(VREF)? (4) Is the FG signal input to the servo IC? � Is FG pulse input to the terminal of IC301"175"(FGIN) according to the rotation of the motor? 5.2.2 Disc Detection, Distinction error (no disc, no RFENV) � Laser is defective. � Front End Processor is defective (IC101). � APC circuit is defective. --- Q101, Q102. � Pattern is defective. --- Lines for CN101 - All patterns which relate to pick-up and patterns between IC101 � IC101 --- For signal from IC101 to IC301, is signal output from IC101 "40" (FE)? 5.2.3 Traverse movement NG (1) Defective traverse driver � Has the voltage come between terminal of CN201 "7" and "8" ? (2) Defective BTL driver (IC201) � Has the motor drive voltage gone out to IC201"11" or "14"? (3) Has the control signal come from the microcomputer? � TRSDRV Is the signal input?
