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 SVC key and then press the /M key. b.Data reset : Press 0 KEY and then OK key. c.Adjustment mode cancellation : Press the /M key.

3) Reset the data in convergence adjustment mode,quit the mode. Adjustment Mode : Press the �SVC� key and then /M key. Data reset : Press the �5� key and then OK key. Adjustment mode cancellation :Press the /M key. 4) Display only the Green raster using lens covers to block Red and Blue.

2. PAL Mode Deflection adjustment
Do not adjust VS ,HS ,VL ,A-ANG ,A-BOW ,SC ,V-ASP in PAL MODE. At SVC mode,press the YELLOW 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 fifth 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. 6) ET(East-west Trapezium) Adjust to make the width of top horizontal line same with it of the bottom horizontal line.

High Voltage Regulation Adjustment
Digital Multi-Meter(DMM)

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

3. Adjustment
1) Connect �+� terminal(Red) of DMM to the P416A of the Deflection PCB, [+] and the �-� terminal(Black) to the P416B,[-]. 2) Adjust VR401 so that the voltage of multimeter to be below voltage. Model except for German model: 21.6 ! 0.1V. German Model: 20.5!0.1V.

CUT-OFF Adjustment
1) Adjustment must be operated in a dark room(simple dark room). 2) Turn the screen volume to the left so that the screen voltage to be MIN. (Entering the horizontal mode when the screen voltage is high may occur the horizontal burning of PRT.)

1.Preliminary steps

2.Adjustment.
1) Press the �SVC�key and then press the key. on the remote controller for adjustment to display horizontal line. (Even though it enter into the Adjustment mode,the horizontal line might not be seen according to the position of Screen Volume.) 2) Adjust Screen Volume (R/G/B) in Focus Pack until brightness of red/blue/green horizontal line is hardly seen. (At the moment,brightness of red,blue or green horizontal line should be equal to one another.) 3) Exit the adjustment mode by pressing the key.

Fifth Vertical Line

7) A-ANG(AFC Angle) Vertical slope adjustment 8) A-BOW(AFC BOW) Vertical get bending adjustment 9) U-C(Upper Corner Pincushion) Upper part pin cushion adjustment 10) L-C(Lower Corner Pincushion) Lower part pin cushion adjustment 11) U-VL(Upper Vertical Linearity) Adjust vertical linearity of upper screen

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.
