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.

7.1.3 HOW TO DIAGNOSE THE UNIT WITH THE POWER AMPLIFIER SECTION REMOVED
Purpose:
A
When repairing this unit, the large Heat Sink Block obstructs access to some Assys. If the Heat Sink Block is removed, as the posistor mounted on it is also disconnected, the protection circuit is activated, which disables failure diagnosis of these Assys while the unit is powered. With the method explained here, the Assys that cannot be diagnosed while the unit is powered because of the Heat Sink Block can be diagnosed by creating an artificial status of the posistor's being connected (by connecting a 100-ohm resistor under normal temperature). Note: Use this method for diagnosing a failure other than possible failures inside the Heat Sink Block, such as those shown in the table below: Symptoms that are highly suspected to be failures inside the Heat Sink Block
1 No power with the MCACC LED flashing
Possible causes
DC detection has been activated to prevent further damage to the unit. Note: Refer to "7.1.2 How to diagnose the Amplifier Section" in the service manual. The peripheral circuits of the posistor inside the Power Amplifier Section are in failure. Note: A posistor is a kind of thermistor, and its resistance is approx. 100 ohms at normal room temperature.
B
2 The unit turns itself off after "AMP ERR" was displayed on the FL display. Then it goes into state 1 above. 3 "OVERHEAT" is displayed on the FL display under normal temperature, then the unit turns itself off. 4 The unit turns itself off without any indication on the FL
Overloaded amplifier, failure in the overload-detection circuit inside the Power Amplifier Section, etc. 5 "FAN STOP" is displayed on the FL display, then the unit turns Disconnection of the Fan connector, failure in the fan. (Only for the itself off. models for Europe and those for other than North America and Japan)

Procedures:
1 Remove the bonnet and center beam. 2 Remove all the wires from the wire saddle. 3 Disconnect all six connectors connected between the Amplifier Assy and the SP/PS Assy.
� Remove the wires.

2
� Disconnect the parallel wires.
4 Disconnect the parallel wires from the connector CN2201. (If the wires are not easily disconnected, disconnect them with the connector attached, using a vacuum desoldering tool.)
E
5 Remove the eight screws that secure the Amplifier section.
