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.

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→ΜΕΝUMUTE 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

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.
