Horizontal Phase (H-PH):
Note: This adjustment centers the video on the raster. It does not move the raster.
1. Enter the Service Default Alignment Mode (SDAM) in either of the following two ways:
a. Press the following key sequence on the remote control transmitter while the set is in Standby
mode:

Base of 7320 on the CRT CBA.
Base of 7310 on the CRT CBA.
Base of 7300 on the CRT CBA.
3. From the SDAM menu, use the Menu Up/Down buttons to highlight CHROMA TRAP.
4. Using the Menu Left/Right buttons, select 0,1,2,3 CHROMA TRAP for minimum color burst.
Note: Try to adjust for minimum color burst at all three points. One register value probably will
not provide the point of minimum color burst at all three points; therefore find the register
value which provides the best possible balance between the three points.
