Alignment and Adjustments

Samsung Electronics 4-1

4. Alignment and Adjustments

4-1 General Alignment Instructions

1. Usually, a color TV-VCR needs only slight
touch-up adjustment upon installation. Check
the basic characteristics such as height,
horizontal and vertical sync and focus.

2. Observe the picture for good black and white
details. There should be objectionable color
shading; if color shading is present,
demagnetize, perform purity and convergence
adjustments described below.

3. Use the specified test equipment or its
equivalent.

4. Correct impedance matching is essential.

5. Avoid overload. Excessive signal from a
sweep generator might overload the front-end
of the TV. When inserting signal markers, do
not allow the marker generator to distort test
results.

6. Connect the TV only to an AC power source
with voltage and frequency as specified on the
backcover nameplate.

7. Do not attempt to connect or disconnect any
wires while the TV is turned on. Make sure
that the power cord is disconnected before
replacing any parts.

8. To protect against shock hazard, use an
isolation transformer.

4-2 Automatic Degaussing

A degaussing coil is mounted around the
picture tube, so that external degaussing after
moving the TV should be unnecessary. But
the receiver must be properly degaussed upon
installation.

The degaussing coil operates for about 1
second after the power is switched ON. If the
set is moved or turned in a different direction,
the power should be OFF for at least 10
minutes.

If the chassis or parts of the cabinet become
magnetized, poor color purity will result. If
this happens, use an external degaussing coil.
Slowly move the degaussing coil around the
faceplate of the picture tube and the sides and
front of the receiver. Slowly withdraw the coil
to a distance of about 6 feet before turning
power OFF.

If color shading persists, perform the
following Color purity and Convergence
adjustments.

4-3 High Voltage Check

CAUTION : There is no high voltage adjustment
on this chassis. The B+ power supply should be
+135 volts (with full color- bar input and normal
picture level).

1. Connect a digital voltmeter to the second
anode of the picture tube.

2. Turn on the TV. Set the Brightness and
Contrast controls to minimum (zero beam
current).

3. Adjust the Brightness and contrast controls to
both extremes. Ensure that the high voltage
does not exceed 30 KV under any conditions.

Alignment and Adjustments

4-2 Samsung Electronics

4-5 SCREEN Adjustment

1. Input Toshiba Pattern

2. Enter “Service Mode”.(Refer to “4-8-1 Service Mode”)

3. Select “G2-Adjust”.

4. Set the values as below.

4-4 FOCUS Adjustment

1. Input a black and white signal.

2. Adjust the tuning control for the clearest picture.

3. Adjust the FOCUS control for well defined scanning lines in the center area of the screen.

5. Turn the SCREEN VR until “MRCR G B” and “MRWDG” are green and those value are about 100.
(The incorrect SCREEN Voltage may result that “MRCR G B” and “MRWDG” should be red)

Alignment and Adjustments

Samsung Electronics 4-3

4-6 E2PROM (IC902) Replacement

1. When IC902 is replaced, all adjustment data revert to the initial values.
So, all adjustment values when servicing should be readjusted.

2. After IC902 is replaced, connect the AC power supply cord.

3. Turn the power switch ON.

4. In stand-by, warm up the TV for at least 10 seconds.

5. Power on the TV.

4-7 White Balance Adjustment

■ Equipment : Color-Analyzer (CA-100)

■ Input Signal : Pattern signal (Toshiba pattern)

1. Select STANDARD from the menu.

2. Input an 100% White pattern.

3. Enter the “Service Mode”. (Refer to “4-8 Service Mode”)

4. Warm up the TV set at least for 30 minutes.

5. Input a Toshiba pattern signal.

6. Enter the “Video Adjust1”.

- Adjust “Sub Contrast” so that Y (luminance) becomes 65 ft ±3.

- Use “Red Drive” and “ Blue Drive” to adjust High-Light (x : 265, y : 265)

- Adjust “Sub Bright” so that Y (luminance) becomes 1.2ft ± 0.3.

- Use “Red Cutoff” and “Blue Cutoff” to adjust Low-Light (x : 265, y : 265).

7. Adjust CA-100 so that the final adjustment value can be fixed.

8. Use the Channel Up/Down (▲/▼) buttons to move the cursor on the adjustment modes.

9. Use the Volume +/- buttons to change the adjustment value.

- If you do not have Factory remote-control

- If you have Factory remote-control

2. After the Service Mode is entered, the initial screen is as shown in the figure below.

3. Use the Channel Up/Down buttons to move the cursor in the adjustment parameters.

Note :

- When CRT, CRT PCB, FBT, E
