GREEN HORIZONTAL SYMMETRICAL PIN DISTORTION ADJUSTMENT

1. Adjust GH MPIN to correct pin distorton at both edges of the centre section.

2. Use GH PIN to correct pin distortion at both edges of the screen.

3. While tracking adjust GH MPIN and GH PIN so that the PIN of vertical lines on the entire screen have no bowing.

4. If there is asymmetrical distortion after adjustments, re-adjust GH MBOW and GH SBOW while tracking.

GREEN VERTICAL 4TH ORDER DISTORTION ADJUSTMENT

1. By using GV 4 PIN, 4th-Order distortion of the horizontal lines at the top & bottom can be corrected. Since there is no 4SBO for vertical correction, there will be a slight imbalnace, but adjust the registration to eleiminate any distortion.

GV 4PIN

GREEN VERTICAL TRAPEZOID AL DISTORTION ADJUSTMENT

1. Adjust GV SSKW so that the tilt of the horizontal lines at the top and bottom of the screen are symmetrical.

2. Adjust GV MKEY so that there is no tilt for the middle section.

3. Adjust GV KEY so that there is no tilt at the top and bottom of the screen.

4. While tracking adjust GV MKEY and GV KEY, so that there is no tilt over the entire screen.

5. If the tilt is unbalanced after GV MKEY and GV KEY

have been adjusted, readjust GV SSKW.

GREEN VERTICAL WAVE (3RD-ORDER) DISTORTION ADJUSTMENT

1. Check the screen at the top & bottom, and look for any 2nd or 3rd order waveform distortion of horizontal lines. Correct with GV WAVE.

2. While tracking adjust GV WAVE and GV KEY, if here are any KEY distortion.

1. Correct the asymmetrical pin distortion at the top and bottom of the screen with GV SBOW.

GV SBOW

GREEN VERTICAL ASYMMETRICAL PIN DISTORTION ADJUSTMENT

1. Using GV MPIN adjust the pin distortion at both edges of the screen and at the centre.

2. Using GV PIN, adjust, so that the horizontal lines at the top & bottom of the screen are straight lines.

3. Adjust GV MPIN & GV PIN so that there is no curve in the horizontal lines on the entire screen.

4. After adjusting the items above, using tracking with GV SBOW. GV MPIN, and GV PIN to correct the entire screen.

GREEN AND BLUE ADJUSTMENT

1. Adjust so that the blue and green lines are on top of each other.

Note : Main registration correction should not be while ad-

justing Blue adjustment.

BEWARE : Not to change Green & Red Sub Items.

It’ s easily done by mistake.

REGISTRATION DATA WRITE

* Points to bear in mind :

There are two independent modes of pictures 4 : 3 MODE

and 16 : 9 MODE

1. Once REGISTRATION 4 : 3 has been adjusted Press "Mute" + 0 >"Data Write"

(write data in NVM)

Press "On screen disp." + 0 >"WRT 5060" Pal to NTSC

(write data Pal/Secam to NTSC) If 2 + 0 is pressed (Data copy) it is recording data from 4 : 3 to 16 : 9 mode. So it should be adjusted in 16 : 9 mode.

GREEN AND RED REGISTRATION ADJUSTMENT

1. Receive a PAL cross-hatch signal.

2. Adjust so that the red lines lay on the green lines. Adjust, using the same procedure as the GREEN SUB adjustment outline above.

Note : Main registration correction should not be while ad-

justing Red adjustment.

BEWARE : Not to change Green Sub Items It’ s easily done

by mistake.

2. Adjust REGISTRATION in 16 : 9 mode. Press "Mute" + 0 >"Data Write"

(write data in NVM)

Press "On screen disp." + 0 >"WRT 5060"Pal to NTSC

(write Pal/Secam to NTSC)

3. Once REGISTRATION has been adjusted in both modes

(4 : 3 and 16 : 9) a) With picture go into service mode b) Press TT and "autoconvergence" button in

control panel and wait for the adjusting

∗ Make sure input signal is PAL. If input signal is NTSC

and do this process, NTSC data are copied to PAL data!

5-5. AGC ADJUSTMENT

1. Receive an off-air signal.

2. Adjust the A GC VR ( IF 1001 ) so that there is no sno w noise and cross-modulation.
