SERVICE ADJUSTMENTS
> As for the test points and respective volume adjusting positions, refer to the "ALIGNMENT LOCATION" on the schematic diagram and the SERVICE ADJUSTMENT in the given herein.
EF & POWER PC BOARD CIRCUIT
’OWER SUPPLY
SUB power voltage (12V DC) Adjust the 12V ADJ VR to obtain 12V DC between TP-96 (+ side of C618) and TP-E( J, ).
Bl voltage (148V DC)
Adjust the Bl ADJ VR to obtain 148V DC between
TP-91 end TP-E( *.).
SUB COLOUR & P/S SUB COLOUR deceive e SECAM (System SW: SECAM) colour bar ignal.
ЧлЬ the standard button and set the Video control to he standard petition.
Adjust the SUB COLOUR VR to obtain natural colour
tensity.
deceive a PAL (System SW: AUTO) colour bar signal. Adjust the P/S SUB COLOUR VR to obtain natural colour density.
Mo. 50123)
 SUB BRIGHT & SUB CONTRAST
1.	Push the standard button and set the Video control to the standard position.
2.	Adjust the SUB BRIGHT VR and SUB CONTRAST VR until an ideal picture is obtained.
	V. CENTER
The screen can be scrolled upward or downward by chansing over the V. CENTER switch.
	H. SIZE & PIN CORRECTION
1.	Adjust the PIN CORRECTION VR to obtain the least deformation of the screen,
2.	Adjust the H. SIZE VR to move the screen horizontally and obtain the optimum screen with the whole image.
 FOCUS
Adjust the FOCUS VR for best overall definition and picture detail at normal brightness and contrast

SIGNAL PC BOARD CIRCUIT
 NOISE (RFA.G.C. Delay)
This control is set at the factory and rarely requires adjustment If a snowly picture appears on a medium- to weak-signal station, adjust the NOISE VR.
1. Tum NOISE VR fully couterclockwise (or clockwise) to obtain maximum noise in picture.
2. Slowly tum NOISE VR clockwise (or counterclockwise) until snow or noise in picture disappears.
• NOTE
Check operation on strong channels. If overloading occurs (bending, poor 'colour, loss of colour sync, etc.) make compromise adjustment
 CHROMA CIRCUIT
• PAL
1.	Receive a PAL colour bar signal (System SW: AUTO) and set the oscilloscope at the X Y mode and then connect CH-I (X-axis) to TP-49 and CH-2 (Y-axis) to TP-48 respectively.
2.	Short the^_C312 capacitor with a jumper wire and connect pin (24) and pin (26) of IC201 with 8.2 resistor. See Lissajous' Fig. (A),
3.	Adjust the P/S SUB COLOUR VR so that the figure is not saturated.
4.	Adjust the DL AMP VR (R338) so that the figure is altered to (B) from (A).
5.	Adjust the DL P TRANSF (T302) so that the figure is altered to (C) from (B).
6.	Repeat adjustments 4, and 5, more than twice,
7.	Remove tlie shorted Jumper wire and 8.2 k£2 resistor from pin (24) and pin (26) of IC201.
8.	Then adjust the T301ATRANSF (T301A: Burst cleaning) so that the figure is minimized to (E) from (D).
WHITE BALANCE ADJUSTMENT (Black and White Tracking)
1.	Display a monochrome pattern.
2.	Set the RED and GREEN DRIVE VRs for their mechanical center.
3.	Turn the RED, GREEN and BLUE CUT-OFF VRs and the SCREEN VR fully counterclockwise.
4.	Display a horizontal line. (Select the CUT-OFF SER- VICE SWITCH from N to S and a HORIZONTAL LINE will appear.)
5.	Turn SCREEN VR slowly clockwise until a very faint horizontal line appears.
6.	Turn the CUT-OFF VR of the color which has appeared first, clockwise by about 10° and then adjust the SCREEN VR again $0 that the color may shine faintly.
7.	Turn the other color CUT-OFF VRs slowly clockwise until a reasonable white line appears.
8.	Return the monochrome pattern. (When returning a monochrome pattern select the CUT-OFF SERVICE SWITCH from S to N and a monochrome pattern will appear.)
9.	Adjust the RED and GREEN DRIVE VRs for best white highlights.
• HORIZONTAL LINE
HOW TO USE THE CUT-OFF SERVICE SWITCH
 VERTICAL HEIGHT & LINEARITY
1.	Set colour bar generator to crosshatch or a pattern with which symmetry can be checked.
2.	Reduce the vertical size with the VERTICAL HEIGHT VR.
3.	Adjust the vertical symmetry with the VERTICAL LINEARITY VR.
4.	Readjust the VERTICAL HEIGHT so that the picture extends to normal size.
 H. CENTER
1.	The screen can be scrolled leftward or rightward by adjusting the H. CENTER VR.
PERI MODULE CIRCUIT	•
 PERI SUB BRIGHT & SUB CONTRAST -
While connecting PERI input in the AV TERMINAL Board.
1.	Push the standard button and set the Video control to the standard position.	~ ....
2.	Then align ihe PERI SUB BRIGHT VR & SUB CONTRAST VR until an ideal Picture is obtained.
 PERI B. CUT OFF & R. CUT OFF
While connecting PERI Input, adjust the BLUE CUT OFF VR AND RED CUT OFF VR In th* FERI circuit until • best White picture Is obtained. r.
