Alignment and Adjustments

Samsung Electronics 2-1

2. Alignment and Adjustments

2-1 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.

2-2 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.

2-3 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

2-2 Samsung Electronics

2-4 FOCUS Adjustment

1. Iput a crosshatch pattern.

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.

2-5 SCREEN Adjustment

1. Input Toshiba Pattern If a Toshiba pattern is not available, Enter “Service Mode” and select “Test pattern 2”(Toshiba pattern)

2. Enter “Service Mode”.

3. Select “G2-Adjust”.

4. Set the values as example

5. Turn the SCREEN VR until “Read Cutoff” and “Read Drive” are green. (The incorrect SCREEN Voltage may result that “Read Cutoff” and “Read Drive” should be red)

ex) IBRM = 175

WDRV = 110 CDL = 250 COLR G B = 110 110 110

2-6 White Balance Adjustment

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

2. Enter the Service Mode by pressing the remote control keys in the following sequence:

Power Off ➞ Info ➞ Menu ➞ Mute ➞ Power On

3. Initialize all set data.

4. Input a Toshiba pattern.

5. Using a probe(CA100), do the White Balance adjustments. (1) Adjust Low-Light.

- Adjust Sub Brightness to set Y.

- Adjust B Cutoff to set y.

- Adjust R Cutoff to set x.

(2) Adjust High-Light.

- Adjust Sub Contrast to set Y.

- Adjust B Drive to set y.

- Adjust R Drive to set x. (3) Check the value of Low-Light. If necessary, readjust Low-Light. (4) Check the value of High-Light. If necessary, readjust High-Light.

2-8 Factory Adjustment

1. To enter the “Service Mode”, Press the remote-control keys in this sequence :

- If you do not have Factory remote-control

- If you have Factory remote-control

2-7 When adjusting Screen Voltage and White Balance

1. Screen Voltage and White Balance are related each other. Make sure both adjustments are correct.

2. Adjust Screen Voltage before White Balance Adjustments. Make sure Screen Voltage is correct.

3. If White Balance has been readjusted, re-check Screen Voltage.

4. After adjustments are complete, check the following.

- If spots appear on the screen after pressing the Power On/Off key, readjust Screen Voltage.

- If flyback lines appear on the screen, readjust Screen Voltage.
