Samsung Electronics
4-3 Beam Alignment
PRECAUTION
1. Input a crosshatch and dot pattern.
2. Select the “STANDARD” video mode.
3. Warm up the TV for at least 10 minutes.
4. Connect an audio oscillator to the pin jig between GT401~GT402 (located on the deflection
PCB) and GND.
5. Determine the ZERO-magnet area (using the beam-alignment CY)
6. Check the squarewave at the point where the focus is misaligned (Use an audio oscillator).
ADJUSTMENT
1. Cover the Red and Blue lenses.
2. Adjust the Green lens as shown in the figures below
3. Adjust the G-Focus until any light around the core disappears.
4. Cover the Green and Blue lenses.
5. Adjust the Red lens using the same method as with the Green lens.
6. Note: The Blue lens is not adjusted because its focus varies little (VM-coil is installed).
7. After the adjustments are completed, disconnect the jig pin connector.
