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.

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

Outstanding quality manual. This is the exact documentation I needed to service my AKAI GX-210D. This is a PERFECT COPY of the service manual for my machine. Outstanding service. Thank-you!
WARNING: BEFORE SERVICING THIS CHASSIS, READ THE �X-RAY RADIATION PRECAUTION�, �SAFETY PRECAUTION� AND �PRODUCT SAFETY NOTICE� ON PAGE 3 OF SERVICE MANUAL.
(SET-UP ADJUSTMENT FOR FLAT TUBE)
s The following adjustments should be made when a complete realignment is required or a new picture tube is installed. Perform the adjustments in order as follows : 1. Color Purity 2. Convergence 3. White Balance Note: The PURITY/CONVERGENCE MAGNET assembly and rubber wedges need mechanical positioning. Refer to figure 1. COLOR PURITY ADUSTMENT (1)Let the screen face in the installing direction or toward the east (when it is to be moved), bring up the service mode screen after demagnetizing (front, left, right, and top) with the degaussing coil, receive white signals by pressing the [TV/VIDEO] button, and then the receiver should be operated for more than 40 minutes. (2)Perform rough adjustment of the central convergence with the P/C magnet according to the adjustment item. (3)Receive built-in green signals, loosen set screws on the deflection yoke, remove rubber wedges, and shift the deflection yoke to toward front. (4)Move alternately the two 2-pole magnets of the P/C magnets so that the green raster can come to the center of the screen. Figure 1.

(5)Receive built-in red and blue signals, check that there is no inclination of the single color raster toward one side, and if each color tilts to a great extent, make adjustment with the 2-pole magnet so that the 3 colors will come to the center evenly. Shift deflection yoke (6)Receive the green raster, shift the deflection yoke from a foremost position (hitting against the picture tube) to a backward position horizontally, stop the deflection yoke at a position where it begins to become a green raster, and perform accurate marking on the picture tube. (7)Shift the deflection yoke further backward, and perform accurate marking at a position where the green raster begins to being luck. (8)Fix the deflection yoke at a position 60% forward within the range marked in items (6) and (7) above. CONVERGENCE ADJUSTMENTS s CENTER CONVERGENCE: (1)Receive the white crosshatch or dot pattern from the service signal generator. (2)Use the 2 pieces of main 4-pole magnets of P/C magnets, change the open angle, and align the red and blue vertical lines on the screen center. (3)Freeze the open angle of the main 4-pole magnets, turn them simultaneously, and align the horizontal lines. (4)Take the same steps for items (2) and (3) above and align red/blue with green on the screen center using two 6-pole magnets.
