Deflection Adjustment
1) NTSC mode should be adjusted after adjusting PAL mode. 2) NTSC adjustment should be done in STANDARD mode of picture after receiving 13CH signal or MULTI 48CH signal,and PAL adjustment should be done in STANDARD mode of picture after receiving EU05 CH. 3) Reset the data in convergence adjustment mode,quit the mode. Adjustment Mode : Press the IN_START key and then �0� key. Data reset : Press the �0� key. Adjustment mode cancellation :Press the ENTER key. 4) Display only the Green raster using lens covers to block Red and Blue.

1. Preliminary steps 2. Adjustment
1) Operate adjustment about Red,Green,Blue centering magnet. 2) SGS-THOMSON Convergence assy Adjust until the center of blue signal is shifted up to 40mm left from that of green signal and center of red signal is shifted up to 40mm right from that of green signal with turning the centering magnet. 3) After adjustment, re-adjust convergence data and exit the adjusting mode. a.Adjustment mode:Press the IN_START key. b.Data reset : Press 0 KEY. c.Adjustment mode cancellation : Press the Enter key.

High Voltage Regulation Adjustment
Digital Multi-Meter(DMM)

Do not adjust V-LIN, S-COR, A-BOW, A-ANG, UCPIN, LCPIN, V-ASP, V-SCR in PAL MODE. At SVC mode, press the �0� key get into the deflection adjustment mode. 1) VS (Vertical Shift) Adjust until the geometric vertical center line is accord with the vertical center line of screen JIG in EU 05 CH by pressing the VOLUME F ,G key. 2) VA (Vertical Amplitude) Adjust until sixth vertical line from upper and lower center of the screen is accord with the last point of the frame. 3) HS (Horizontal Shift) Adjust until the geometric horizontal center line is accord with the horizontal center line of screen JIG. 4) EW (East-west Width) Adjust until the outermost left and right vertical line of the screen is accord with the last point of the frame. 5) EP (East-west Parabola) Adjust so that middle portion of the outermost left and right vertical line looks like parallel with vertical lines of the PRT.

1. Test Equipment 2. Preparation for Adjustment.
Select picture mode to �DYNAMIC� in no signal input.

3. Adjustment
1) Press the IN_START key and then press �1� key.(HV ADS) 2) Connect �+� terminal(Red) of DMM to the P415 of the Deflection PCB, [+] and the �-�terminal(Black) to the P416,[-]. 3) Adjust VR401 so that the voltage of multimeter to be below voltage. Voltage : 21.7 ! 0.1V. 4) Exit the adjustment mode by pressing the enter key
