Set-Up Adjustments; Beam Landing; Convergence - Sony TRINITRON KV-36FS10 Service Manual

The following adjustments should be made when a
complete realignment is required or a new picture
tube is installed.
These adjustments should be performed with rated
power supply voltage unless otherwise noted.
The controls and switch should be set as follows
unless otherwise noted:
PICTURE control ................. normal
BRIGHTNESS control ......... normal

3-1. BEAM LANDING

Preparation:
•
Input a white pattern signal.
•
Face the picture tube in an East or West direction to reduce the influence of geomagnetism.
NOTE: Do not use the hand degausser because it magnetizes the CRT .
1. Input white pattern from pattern generator.
2. Loosen the deflection yoke mounting screw, and set
the purity control to the center as shown below:
3. Input green pattern from pattern generator.
4. Move the deflection yoke backward, and adjust with
the purity control so that green is in the center and
red and blue are even on both sides.
