alignment and adjustments samsung electronics 4-1 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 pictur e and check for good black and white details. ther e must be no objectionable color shading: if color shading is pr esent, demagnetize the r eceiver . if color shading persists, r e-do purity and conver gence adjustments. note : 1. this ?. 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 r emote-contr ol model adopting k55a chassis. depending on sales location and pr oduct specifications, some of specifications her ein may be changed. 4-1-2 focus adjustment k55a contains a dynamic focus cir cuit. when cr t pcb, fbt or cr t is r eplaced, be sur e to adjust in the following sequence: dynamic focus adjustment 1. input a cr osshatch pattern. 2. select ?tandar d?fr om the menu, 3. t urn the static focus vr clockwise to set it to its maximum. 4. t urn the dynamic focus vr counter clockwise to set it to its maximum. 5. t urn the static focus vr counter clockwise slowly for the clear est center vertical line. 6. t urn the dynamic focus vr clockwise slowly for the clear est thir d line. 7. check for the focus of entire screen. if necessary, re-do adjustments 3~6. after adjustment 1 2 3
alignment and adjustments 4-2 samsung electronics 4-1-3 screen v oltage adjustment 1. input a t oshiba pattern. 2. use an oscilloscope to identify rk, bk, gk. and then adjust fbt scr een vr so that the voltage of pedestal level doesn? exceed 160v . if a t oshiba pattern is not available, cancel the blue scr een and input ?o signal?to a v in so the voltage of pedestal level doesn? exceed 175v . if an oscilloscope is not available, use a dc multi-meter in no signal (black scr een) to adjust rk, bk, gk so that the highest voltage becomes 160vp-p. 4-1-4 white balance adjustment 1. w arm up the tv set for at least 30 minutes. 2. enter the service mode by pr essing the r emote contr ol keys in the following sequence: power of f display menu mute power on 3. initialize all set data. 4. input a t oshiba pattern. 5. using a pr obe(ca100), do the white balance adjustments. (1) adjust low-light. - adjust sub brightness to set y . - adjust b cutof f to set y . - adjust r cutof f 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 , r eadjust low-light. (4) check the value of high-light. if necessary , r eadjust high-light.15
