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,

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.

6.2 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT
A
� Note : The grating angle of the PU unit cannot be adjusted after the PU unit is changed. The PU unit in the CD mechanism module is adjusted on the production line to match the CD mechanism module and is thus the best adjusted PU unit for the CD mechanism module. Changing the PU unit is thus best considered as a last resort. However, if the PU unit must be changed, the grating should be checked using the procedure below. � Purpose : To check that the grating is within an acceptable range when the PU unit is changed. � Symptoms of Mal-adjustment : If the grating is off by a large amount symptoms such as being unable to close tracking, being unable to perform track search operations, or taking a long time for track searching. � Method : � Measuring Equipment � Measuring Points � Disc � Mode

� Checking Procedure 1. In test mode, load the disc and switch the 3V regulator on. 2. Using the � and � buttons, move the PU unit to the innermost track. 3. Press key 3 to close focus, the display should read "91". Press key 2 to implement the tracking balance adjustment the display should now read "81". Press key 3. The display will change, returning to "81" on the fourth press. 4. As shown in the diagram above, monitor the LPF outputs using the oscilloscope and check that the phase difference is within 75° . Refer to the photographs supplied to determine the phase angle. 5. If the phase difference is determined to be greater than 75° try changing the PU unit to see if there is any improvement. If, after trying this a number of times, the grating angle does not become less than 75° then the mechanism should be judged to be at fault. � Note Because of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may be seen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates the average angle. � Hint Reloading the disc changes the clamp position and may decrease the "wobble".
