Alignment and Adjustments
Samsung Electronics 2-3
(4) Video adjustment should be performed with the Toshiba pattern in RF video mode.
The adjustment should be the same as in step 1.
Also, the video signal uses the video port when there is no other input signal. However, the signal uses the graphic
port in PIP mode, which includes other input signals (PC, DVI, Component, etc.), Video adjustment should be performed with
Video port and Graphic port separately.
* Thus, Micom saves the W/B data separately for each memory mode of the block (See the block diagram given below) during
W/B adjustment.
