ADJUSTMENT INSTRUCTIONS
1. Safety Precautions
1. It is safe to adjust after using insulating transformer between the power supply line and chassis input to prevent the risk of electric shock and protect the instrument. 2. Never disconnect leads while the TV receiver is on. 3. Don't short any portion of circuits while power is on. 4. The adjustment must be done by the correct appliances. 5. Unless otherwise noted, set the line voltage to 230Vac!10%, 50Hz. 6. The adjustment of TVshould be performed after warming up for 15 minutes.
5. Screen Voltage & White Balance Adjustment
5-1. Adjustment of screen manually (Using ADJ.Remote Control)
1) Receive the PAL or SECAM(NTSC) signal into RF mode regardless of channel. 2) If you press the "ADJ"button in LINE SVC mode(IN-START button),the LINE SVC mode changes to screen adjustment mode. 3) Turn the Sreen Volume of FBT to change luminance of White signal center as shown below.(Deviation ! 1FL) 4) Press the EXIT button (Like TV/AV) to exit SVC mode. CPT & INCH 29" FLAT 25" FLAT 29" NORMAL 25" NORMAL 28" NORMAL Luminance(Manual) 6!1FL 8!1FL 5!1FL 6!1FL 8!1FL Note Single Focus
2. Test Equipment required
1. 2. 3. 4. 5. RF signal generator (with pattern generator) DC Power Supply Multimeter (volt meter) Oscilloscope Color analyzer
3.DVCO Adjustment
1) This is for adjustment of VCT38XX,crystal oscillator frequency after receiving a company Digital pattern.(PAL:EU05CH,NTSC:13CH) 2) When entering adjustment mode by pressing IN-START button,DVCO adjustment is operating automatically. (T/X doesn't operating occassionally during DVCO adjustment.)
5-2. Adjustment of white balance manually(LIne-SVC 1)
1) 2) 3) 4) Tune the TV set to receive an 100% white pattern. Adjust LOW LIght status of CUT R,CUT B at CUT G:50. Adjust HIGH LIght status of WDR R,WDR B at WDR G:380. Repeat above step 2) and 3) for the best condition each status of High Light and Low Light. White Balance Color analyzer
4. Focus Adjustment
4-1. Preparation for Adjustment
Tune the TV set to receive a digital pattern.

4-2. Adjustment Method
1) Single Focus CPT Adjust the upper Focus volume of FBT for the best focus of horizontal line A,vertical line B. 2) Double Focus CPT 1) Adjust the lower Focus volume of FBT for the best focus of vertical line B. 2) Adjust the upper Focus volume of FBT for the best focus of area A. 3) Repeat above step 1) and 2) for the best overall focus.

6. Deflection Data Adjustment (Line SVC-2)
NOTE : How to enter into the Line Service Mode with a remocon. 1.Power off. 2.Press the Red button. 3.Press the Green button. 4.Press the Yellow button. 5.Press the Cyan button. 6.Press the OK button. 7.Power On.
EW (Horizontal Width) Adjust to that a digital circle pattern looks like exact circle.
6-1. Preparation for Deflection Adjustment
1) At adjustment mode(IN-START button on remote control of adjustment),changed to LINE SVC 2 mode to adjust the deflection. 2) Press Channel UP/DOWN button for desirous function Adjustment. 3) Press Volume UP/DOWN button to adjust the data. 4) Tune the TV set to receive a Digital pattern.(PAL:05CH) NOTE : If production line doesn't the production line of LG TV,receive available deflection adjustment pattern.
Fig. 2 EP (East-west Parabolar) Adjust so that middle portion of the outermost left and right vertical line looks like parallel with vertical lines of the CPT. EC (East-west Coner) Adjust so that the vertical line at every 4 corners of the screen looks like parallel with the vertical lines of the CPT. ET (East-west Trapezium) Adjust to make the length of top horizontal line same with it of the bottom horizontal line. PIP (PIP Position) Adjust until the distance between PIP and main picture becomes about 1~2mm.
6-2. Adjustment Method
NOTE : First,adjust deflection at N50Hz,W50Hz,Z50Hz of PAL signal.Then adjust deflection at N60Hz,W60Hz,Z60Hz of NTSC signal. In case of NTSC only model,adjust deflection of N60Hz,W60Hz,Z60Hz of NTSC signal. Store the deflection adjustment data in EEPROM by using ENTER button before adjusting PIP position. 1) When adjusting a deflection,adjust N50Hz of PAL signal first and adjust a deflection at W50Hz,Z50Hz,N60Hz,W60Hz,Z60Hz of PAL signal. 2) Adjust a deflection as shown below PAL 4:3=> PAL 16:9=>PAL ZOOM=>NTSC 4:3=>NTSC 16:9=>NTSC ZOOM. 3) After finishing deflection adjustment,press the ENTER button to enter or exit in SVC mode. VL (Vertical Linearity) Adjust so that the boundary line between upper and lower half is in accord with geometric horizontal center of the CPT. VA (Vertical Amplitude) Adjust so that the circle of a digital circle pattern may be located within the effective screen of the CPT. SC (Vertical "S" Correction) Adjust so that all distance between each horizontal lines are to be the same. VS (Vertical Shift) Adjust so that the horizontal center line of a digital circle pattern is in accord with geometric horizontal center of the CPT. HS (Horizontal Shift) Adjust so that the vertical center line of a digital circle pattern is in accord with geometric vertical center of the CPT.
