Service Adjustments and Calibrations
REQUIRED EQUIPMENTS / CONNECTIONS:
Oscilloscope  bigger than 5MHz: Connect to TP2 or TP35.
PROCEDURE:
1. Position a jumper between TP38 and GND (COLD).
2. Apply a COLOURBAR pattern with 100IRE level.
3. Adjust the  SUB-BRIGHT (DAC:B2) to that black level
can’t be compressed.
4. Adjust the  SUB-CONTRAST (DAC:B3) to obtain [A]
between black level and  white level on TP2 (E-board) or
TP35 (Y-board).
5. Remove the jumper on TP38
PAL SUB-COLOR  ADJUSTMENT
REQUIRED EQUIPMENTS / CONNECTIONS:
Oscilloscope: Connect to TP2 .
PREPARATION:
1. Picture Menu      DYNAMIC
2. CONTRAST       Max. or Normal
3. BRIGHT             Center or Normal
4. SHARPNESS     Center or Normal
5. COLOR              Center or Normal
PROCEDURE:
1. Position a jumper between TP38 and GND (COLD)
2. Apply a COLORBAR pattern.
3. Check if the image is on DYNAMIC mode.
4. Adjust the  SUB-BRIGHT (DAC: B2) to [A] of threshold
level to the wave form doesn’t be compressed.
5. Adjust the  SUB-COLOR (DAC: B0) to obtain [B] as
showed below.
6. Remove the jumper on TP38
[A]
NTSC SUB-TINT ADJUSTMENT
REQUIRED EQUIPMENTS / CONNECTIONS:
Oscilloscope: Connect to TP1 (E-board) or (Y-board)
PREPARATION:
1. BRIGHT                   Center or Normal
2. COLOR                    Center or Normal
3. TINT                         Center or Normal
4. CONTRAST             Max. or Normal
5. COLOR SYSTEM    AUTO or NTSC
PROCEDURE:
1. Position a jumper between TP38 and GND (COLD)
2. Apply a Rainbow pattern.
3. Adjust the  SUB-TINT (DAC: B1) to get, on TP1 or TP36
a waveform like showed below
4. On user mode, check that the TINT control move the
phase TINT more than  ±30
°
.
SUB-BRIGH  PRE-ADJUSTMENT
PREPARATION:
1. SYSTEM MODE      NTSC or Auto
2. COLOR                    Center or Normal
3. CONTRAST             Max. or Normal
4. BRIGHT                   Center or Normal
PROCEDURE:
1. Apply a standard  SUB-BRIGHT (DAC: B2) to the center
of PART 6 and  PART 7 became black.
(PART 7=Black and PART 6=Lightly Illuminated)
