Geometry Adjustments:
Notes:
1. The following Geometry adjustments were performed with a Sencore VG91 Universal Video
Generator.
2. Set the VG91 Generator as follows: STD TV Ch. 3, RF-IF Range set to HI, RF-IF Level set to
NORMAL (1), Video Pattern = Raster, R-G-B raster controls OFF, crosshatch or center cross pattern
as required.
3. Connect the RF output of the generator to the Television Antenna Input, and adjust the VG91 level to
remove any snow from the raster.
Vertical Shift (VSH):
1. Enter the Service Alignment Mode (SAM) by pressing the following key sequence on the remote
control transmitter:
0-6-2-5-9-6-Status
Do not allow the display to time out between entries while keying the sequence.
2. From the top level SAM menu, use the Menu Up/Down keys to highlight the Geometry sub menu.
3. Use the Menu Left/Right keys to enter the Geometry sub menu.
4. In the Geometry sub-menu, use the Menu Up/Down buttons to select VAM.
5. Input a center cross pattern to the antenna/cable input terminal.
6. Using the Menu Left/Right keys, adjust VSH so that the horizontal bar is properly centered, top to
bottom.
7. If other Geometry adjustments are needed, proceed to the necessary adjustment using the Menu
Up/Down buttons.
8. Upon completion of Geometry adjustments, press the Menu button to return to the top level SAM
menu.
Vertical Amplitude (VAM):
1. Enter the Service Alignment Mode (SAM) by pressing the following key sequence on the remote
control transmitter:
0-6-2-5-9-6-Status
Do not allow the display to time out between entries while keying the sequence.
2. From the top level SAM menu, use the Menu Up/Down keys to highlight the Geometry sub menu.
3. Use the Menu Left/Right keys to enter the Geometry sub menu.
4. In the Geometry sub-menu, use the Menu Up/Down buttons to select VAM.
5. Input a crosshatch pattern to the antenna/cable input terminal.
