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.

Once again, excellent price and manual delivered in a timely manner and as advertised!

6. Connect the TV only to an AC power source with voltage and frequency as specified on the back cover nameplate. 7. Do not attempt to connect or disconnect any wires while the TV is turned on. Make sure that the power cord is disconnected before replacing any parts. 8. To protect against shock hazard, use an isolation transformer.
4-3-2 Automatic Degaussing
A degaussing coil is mounted around the picture tube, so that external degaussing after moving the TV should be unnecessary. 8ut the receiver must be properly degaussed upon installation . The degaussing coil operates far about 1 second after the power is switched ON. If the set is moved or turned in a different direction, the power should be OFF far at least 10 minutes. If the chassis or parts of the cabinet become magnetized, poor colar purity will result. If this happens, use an external degaussing coil. Slowly move the degaussing coil around the faceplate of the picture tube and the sides and front of the receiver. Slowly withdraw the coil to a distance of about 6 feet before turning power OFF. If colar shading persists, perform the following Colar Purity and Convergence adjustments.
4-3-3 High Voltage Check
CAUTION : There is no high voltage adjustment chassis. The 8+ power supply should be +8.5 volts (see table 1). 1. Connect a digital voltrneter to the second anode of the picture tube. 2. Turn on the TV. Set the 8rightness and Contrast controls to minimum (zero beam current). 3. Adjust the 8rightness and Contrast controls to both extremes. Ensure that the high voltage does not exceed Maximum High voltage (see table 1 ) under any conditions.
