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.

4-4 Other Adjustments
4-4-1 Screen Adjustment
1. Warm up the TV for at least 30 minutes.
2. Turn to the Video Mode (No Signal) using a
remote-control.
3. Connect an oscilloscope to RK,GK,BK.
4. Adjust the VR (VR501, VR531, VR561) screen
so that RK, GK, BK pulse is 20Vp-p each.
(Turn the R,G,B VR screen fully
counterclockwise in the area of each flyback
line.)
4-4-2 White Balance Adjustment
1. Select the “STANDARD” video mode.
2. Input 100% white pattern.
3. In the stand-by mode, press the remote-control
keys in the following sequence:
DISPLAY→ΜΕΝU→MUTE →Power On
4. Warm up the TV for at least 30 minutes.
5. Input a 10-step signal.
6. R-cut off, B-cut off, and G-cut off by pressing
the Volume +/- keys.
7. Adjust the low light with viewing the dark
side of the screen.
8. Select R-drive, G-drive, and B-drive by
pressing the Volume +/- keys.
9. Adjust the high light with viewing the light
side of the screen.
10. If necessary, redo adjustments 6~9.
11. Press the Menu key to exit.
4-4-3 Sub-Brightness Adjustment
1. Input a sub-brightness adjustment signal.
(TOSHIBA PATTERN)
2. In the stand-by mode, press the remote-control
keys in the following sequence :
DISPLAY→ΜΕΝU→MUTE →Power On
3. Select SBT by pressing the Volume +/- keys.
4. Adjust so that the 7th step on the right side of
the screen is not seen (Use the Volume +/-
keys).
5. Press the Menu key to exit.
4-4-4 High Voltage (31KV) Check
PRECAUTION
1. Input a lion head pattern.
2. Select “STANDARD” video mode.
3. Warm up the TV for at least 10 minutes.
4. Use a 1000:1 probe.
ADJUSTMENT
1. Connect the (+) terminal of the 1000:1 probe to
the high voltage distributor and the (-)
terminal to GND (located on the deflection
board).
2. Adjust VR471 (located on the deflection board)
so that the digital meter indicates
DC 31V ±0.1V.

Alignment and Adjustments
Samsung Electronics 4-9
4-4-5 F.S. (Fail Safe) Circuit Check
Note : The F.S. Circuit check must be performed
after servicing.
1. Turn on the TV.
2. Select the “STANDARD” video mode.
3. Short GT18, GT17 (located on the
Convergence PCB). Then, both sound and
picture disappear. (Note: Even if the shorted
terminals are removed, both sound and
picture do not appear. This proves the F.S.
circuit is working. )
4. To restore both sound and picture, turn off the
TV and reset it after about 30 seconds.
4-4-6 Static Focus Adjustment
PRECAUTION
1. Select the “STANDARD” video mode.
2. Input a crosshatch pattern.
3. Cover the lenses that are not being adjusted.
4. Connect a convergence jig and read data.
5. Adjust the lens for best focus.
(See Fig, 4-1, next page)
STATIC FOCUS (CONTINUED)
Vary the focus pack VR (Red, Blue) on the
front cabinet. Adjust the TV for best possible
focus around the center of the crosshatch
pattern, without losing overall screen balance.
Figure Crosshatch Pattern
Examine these points together.
4-4-7 Lens Focus Adjustment
PRECAUTIONS
1. Do this adjustment after the static focus
adjustment and the tilt adjustment.
2. Select the “STANDARD” video mode.
(Contrast:64, Brightness:32)
3. Input a crosshatch pattern.
ADJUSTMENT
1. Loosen the lens screws.
2. Cover the two lenses that are not being
adjusted.
3. Adjust the lens, observing the color aberration
vertically and horizontally within 3 blocks of
the center of the crosshatch pattern.
4. When the lens is turned clockwise, the color
aberration will change as follows:
Lens Color Aberration Change
R Orange - Crimson
G Blue - Red
B Purple - Green
5. Green lens adjustment:
Set the lens at the point where Blue just
changes to Red. If the color aberration is
irregular throughout the picture screen, adjust
the lens to show Red color aberration
(approximately 1~3 mm area) within a 3-block
grid around the horizontal center-line. If the
color aberration is irregular, adjust the lens as
shown in the diagram below. (Accurate
alignment of Green is important for overall
color quality.)
6. Red lens adjustment
Set the Red lens at the point where Orange
becomes Crimson.
7. Blue lens adjustment
Set the Blue lens at the point where Purple
becomes Green.
