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.

Before adjustment, set the diversity to 1 so as to prevent the circuit from operating during input signals are weak (use �1� input for antenna input). Use rear monitor or OSD output for the video monitor.
Procedure Adjustment Item 1 Diversity adjustment Input signal Adjustment Adjustment method Point Monitor the voltage of pin 2 of IC1001 (PM0013AM) and adjust the DC voltage to 2.5V ± 0.1V.(DC V Meter(1)) Note: If this has not been adjusted properly, extreme diversity switching occurs even with good receiving conditions, causing voice interruption. 2 Center meter Receive TV point adjustment B signals (US Band 10ch) L401 Monitor the voltage between pins 9 and 12 of IC401 (LA1145M) and reduce the potential difference between both edges to zero. (Center Meter) Note: If this has not been adjusted properly, the voice becomes low too fast as input signals become weak. Even worse, sound may be strained or no sound output. 3 SD adjustment Receive TV point B signals (US Band 10ch) RF level: 33 dBµ 4 RGB level adjustment Input white 100% with burst signal 1Vp-p to VTR1. VR801 VR402 Monitor the voltage of pin 19 of IC401 (LA1145M) and adjust the DC voltage to 2.5V ± 1.0V.(DC V Meter(2)) Note: If this has not been adjusted properly, seek may stop even without any signal input or may not stop even when turning input signals stronger. Turn the TV on and enable VTR1 using the menu screen setting. Set the source to VTR1 and monitor the waveform of pin 2 of RGB monitor output CN4801. Adjust the video output of pin 2 as follows: When the RGB monitor or 75� is connected to CN4801: 0.7Vp-p ± 0.1V (Oscilloscope(1))
Receive TV signals. TC1001
When nothing is connected to CN4801: 1.4Vp-p ± 0.2V (DSENS(Pin 12):Connect to GND) Note: If this has not been adjusted properly, the screen becomes too 5 OSD clock adjustment Input white 100% with burst signal 1Vp-p to VTR1 TC2801 bright or dark. Before this adjustment, connect the RGB monitor (since return synchronous signals are required to be input from the monitor). Connect AVX-7000. Turn the TV on and enable VTR1 using the menu screen setting. Set the source to VTR1 and display the OSD menu screen. Adjust the screen so that the OSD display comes center. Note: If this has not been adjusted properly, the menu screen OSD display shifts. Set the MODE switch (S1001) to the FM modulator mode. Connect a multi-CD and start-up the source with the CD. Set the modulator frequency to 89.1 MHz on the menu screen. Monitor the collector voltage (positive side of C537) of Q503 and adjust the DC voltage to 3.0V ± 0.1V.(DC V Meter(3)) Note: To use the menu screen, connect an RGB monitor. Note: If this has not been adjusted properly, RF is strained when the modulator frequency is low or high.
