Notes: • Perform the following adjustments after completing the
Screen Voltage, High-Voltage, Focusing and X-Ray Pro-
tector adjustments.
• Ensure that CN0RD and CN00R on the S. Correction PWB
are connected to the Deflection Yoke and Main PWB.
• If the S. Correction PWB has VR503 on it, adjust the im-
age tilting by turning VR503 instead of using the remote
control cord (DY01).
1. Apply the 1080/60i size adjustment signal to INPUT A (Terminal Y
on the Component/RGB Input Card).
2. Adjust DY01 of the Service Menu to decrease the image tilting to no
more than 2 mm. If the reference point which is the vertical center
position on the left of the image (reference points) is deviated, ad-
just DM04 to correct it.
