Quality scan, great manual. I solved my problem with this manual.
;
The AKAI 1720 model reel to reel tape recorder described in this Manual is quite an old unit - circa late 1960's. As a consequence, the description of the mechanical details - and adjustments thereof - is quite critical. The manual does this quite well. The schematics are also well presented and have detailed PCB overlays. Probably the only negative is that some half-tone detail has been lost from the original manual as it has been scanned in simple B&W.

Perfect source for service manuals: fast and professional transaction; high quality, perfect readable and largely scaleable PDF; complete schemes, diagrams and spare part list. Tnx a lot, cu again!!!!

I got your link from a friend and I must say that I am really satisfied with your service. Specially this B&O manual I didn't find anywhere on the web... but you could deliver it :-) . You deliver very fast and the copy is of good quality. So your webpage is bookmarked. Thanks

The price was reasonable.
The permission to download was quck.
I will use Owner-Manual.com for all my manual needs.

Definition of Pixel Defects
3. Pixel Defect Tolerances In order to qualify for repair or replacement due to pixel defects during the warranty period, a TFT LCD panel in a PHILIPS flat panel monitor must have pixel or subpixel defects exceeding the tolerances listed in the following tables.
0. General
This section explains the different types of pixel defects and defines acceptable defect levels of each type. In order to qualify for repair or replacement under warranty, the number of pixel defects on a TFT LCD panel must exceed these acceptable levels.
1. Definition of Pixels and Subpixels
A pixel, or picture element , is composed of three subpixels in the primary colors of red, green and blue. Many pixels together from an image. When all subpixels of a pixel are lit, the three colored subpixels together appear as a single white pixel. When all are dark, the three colored subpixels together appear as a single black pixel. Other combinations of lit and dark subpixels appear as single pixels of other colors.
BRIGHT DOT DEFECTS MODEL 1 lit sub pixel 2 adjacent lit sub pixels 3 adjacent lit sub pixels (one white pixel)
ACCEPTABLE LEVEL 300WN5 3 or fewer 0 0
