4-1 Adjustments

4-1-1 General Alignment Instructions
Usually, a color TV needs only slight touch-up adjustment upon installation. Check the basic characteristics such as vertical size, horizontal size, and focus. Observe the picture and check for good black and white details. There must be no objectionable color shading: If color shading is present, demagnetize the receiver. If color shading persists, re-do purity and convergence adjustments. Note : 1. This 4. Alignment and Adjustments applies to K55A chassis applications. 2. AC Power Supply: 160~300V or 100~240V, 50Hz 3. This service manual has been written on the basis of domestic remote-control model adopting K55A chassis. Depending on sales location and product specifications, some of specifications herein may be changed.

4-1-2 Focus Adjustment

K55A contains a dynamic focus circuit. When CRT PCB, FBT or CRT is replaced, be sure to adjust in the following sequence: Dynamic Focus Adjustment 1. Input a crosshatch pattern. 2. Select Standard from the menu, 3. Turn the Static Focus VR clockwise to set it to its maximum. 4. Turn the Dynamic Focus VR counterclockwise to set it to its maximum. 5. Turn the Static Focus VR counterclockwise slowly for the clearest center vertical line.

After Adjustment

6. Turn the Dynamic Focus VR clockwise slowly for the clearest third line.
7. Check for the FOCUS of entire screen. If necessary, re-do adjustments 3~6.

4-1-3 Screen Voltage Adjustment
1. Input a Toshiba pattern. 2. Use an oscilloscope to identify RK, BK, GK. And then adjust FBT Screen VR so that the voltage of pedestal level doesnt exceed 160V. If a Toshiba pattern is not available, cancel the blue screen and input No Signal to AV IN so the voltage of pedestal level doesnt exceed 175V. If an oscilloscope is not available, use a DC multi-meter in No Signal (black screen) to adjust RK, BK, GK so that the highest voltage becomes 160Vp-p.
4-1-4 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 Display 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.15
4-1-5 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.
