Alignment and Adjustments 4. Alignment and Adjustments 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 KS4A chassis applications. 2. AC Power Supply: 220 V only 3. This service manual has been written on the basis of domestic remote-control model adopting KS4A chassis. Depending on sales location and product specifications, some of specifications herein may be changed. 4-1-2 Focus Adjustment KS4A 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. STATIC FOCUS VR H DYNAMIC FOCUS VR V NO USE After Adjustment 6. Turn the Dynamic Focus VR clockwise slowly for the clearest third line. 1 2 3 7. Check for the FOCUS of entire screen. If necessary, re-do adjustments 3~6. Samsung Electronics 4-1 Alignment and Adjustments 4-1-3 Screen Voltage Adjustment 1. Enter the Service Mode by pressing the remote control keys in the following sequence : Power Off Mute 1 8 2 Power On 2. Initialize all set data. 3. Input a Toshiba pattern. 4. Use an oscilloscope to identify RK, BK, GK. And then adjust FBT Screen VR so that the voltage of pedestal level doesn't exceed 175V. If a Toshiba pattern is not available, cancel the blue screen and input "No Signal" to AV IN so the voltage of pedestal level doesn't exceed 188V. 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 175Vp-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 -> Mute 1 8 2 Power On 3. Initialize all set data. 4. Input a Toshiba pattern. 5. Using a probe (CA100), do the White Balance adjustments. a) Adjust Low-Light. - Adjust Sub Brightness to set Y. - Adjust B Cutoff to set y. - Adjust R Cutoff to set x. b) Adjust High-Light. - Adjust Sub Contrast to set Y. - Adjust B Drive to set y. - Adjust R Drive to set x. c) Check the value of Low-Light. If necessary, readjust Low-Light. d) Check the value of High-Light. If necessary, readjust High-Light.15 4-2 Samsung Electronics Alignment and Adjustments 4-1-5 When adjusting Screen Voltage and
