Y Safety Precautions1. It is safe to adjust after using insulating transformer

between the power supply line and chassis input toprevent the risk of electric shock and protect theinstrument.

2. Never disconnect leads while the TV receiver is on.3. Don't short any portion of circuits while power is on.4. The adjustment must be done by the correct appliances.

But this is changeable in view of productivity.5. Unless otherwise noted, set the line voltage to 230Vac!10%,

50Hz.

Y Test Equipment required1. RF signal generator (with pattern generator)2. DC Power Supply3. Multimeter (volt meter)4. Oscilloscope5. Color analyzer

: RF AGC (Automatic Gain Control) Adjustment

The RF AGC was aligned at the time of manufacture foroptimum performance over a wide range condit ions.Readjustment of RF AGC should not be necessary unlessunusual local conditions exist, such as ;

1) Channel interference in a CATV system.2) Picture bending and/or color beats, which are unusually

due to excessive RF signal input when the receiver is tooclose to a transmitting tower or when the receiver isconnected to an antenna distribution system where the RFsignal has been amplified. In this case, the input signalshould be attenuated (with pad or filter) to a satisfactorylevel.

3) Picture noise caused by "broadcast noise" or weak signal.If the broadcast is "clean" and the RF signal is at least1mV (60dBu), the picture will be noise free in any area.

Adjusting RF AGC to one end of rotation will usually cause arelatively poor signal to noise ratio;Adjusting to the other end of rotation will usually cause adegradation of over load capabilities resulting in color beats oradjacent channel interference.

: Screen Voltage Adjustment

1) Input the Color Bar Pattern into Antenna jack.2) Select CutOff of SVC-3 mode.3) Turn the screen control clockwise until the Horizontal line

is visible and turn it counterclockwise until the Horizontalline is faintly visible.

: Focus Adjustment

NOTE: This adjustment should be performed after warmingup for 10 minutes.

1) Input the Color Bar Pattern into Antenna jack.2) Adjust the Focus control of FBT for best overall focus.

: VCO Adjustment

1) Input Digital Pattern into Antenna jack.2) Select A-PIF of SVC-4 mode.3) Press VOLF/G button and A-PIF will be changed 0 to 1

while the number of PIF-C is rolling.4) When PIF-C stops rolling, A-PIF will be changed 1 to 0 and

VCO adjustment is finished.

Caution : Do not press the Volume button again in A-PIF modeafter adjustment is finished.

Adjustment

1. Connect RF signal (65dB!0.5dB) and turn on the TV.2. Press OK buttons on TV set and Remote Controller at the

same time to get into SVC mode.3. Press Channel UP/DOWN button on the Remote Controller

several times to find AGC.4. Press Volume UP/DOWN button until the AGC Voltage is

the same as the Table below.5. Press OK(Y) button to memorize the data.

1. To get into SVC mode1) Press OK buttons on both TV set and Remote Control at

the same time.2) Press Yellow button to select OPTION-1, OPTION-2,

OPTION-3 or OPTION-4.3) Press PR E/D button to select an adjustment.4) Press VOL F/G button to change the data.

2. To memorize the adjusted data into EEPROM Press OK button.

3. To get out from SVC modePress TV/AV or Power button.

: Deflection Data Adjustment (Line SVC-2)

1. Preparation for Adjustment 1) Select SVC-2 Mode.2) Tune the TV set to receive Digital Pattern and set ARC

Mode to Standard.

2. Initial deflection data and average data for CPT

3. Adjustment

1) VL(Vertical Linearity) AdjustmentSelect VL adjustment mode to adjust the upper and lowervertical size to be the same for horizontal center line.

2) VS(Vertical Shift) AdjustmentAdjust the geometrical horizontal center line of the screen tobe coincided with the vertical center line of CPT.

3) VA(Vertical Amplitude) AdjustmentAdjust the upper and lower part of big circle of the receivedpattern to be placed on 6~7mm from the valid screen.

4) HS(Horizontal Shift) AdjustmentAdjust the geometrical vertical center line of the receivedscreen to be coincided with the horizontal center line of CPT.

5) SC(Vertical S Correction) AdjustmentAdjust the width of upper/center/lower grid of the receivedpattern to be the same.

: SECAM Background Color Adjustment(CT-, CF-)

1. Preparation for Adjustment Select ÒS R-YÓ or ÒS B-YÓ of SVC Mode 4.

2. AdjustmentWhile switching SECAM and PAL channels in turns, press VOLF/G key until the background color of SECAM channel to bethe same as that of PAL Pattern at S R-Y or S B-Y.

: White Balance Adjustment.(LINE SVC-1)

NOTE : This adjustment should be performed after screen voltageadjustment.

1) Tune the TV set to receive 100% white pattern.2) Select SVC-1 Mode.3) Press PR UP/DOWN key to select BG, GG, BG, GC.

Adjust BG, GG on Brightness 40!1FL and BG, GC onBrightness 4.5!0.5FL with VOLF/G key to get the color value.

4) Adjust BG, GG from the initialized data to get the color value ofX=281!8, Y=288!8.

5) R,G,B initial data and average data

: Sub Brightness Adjustment

NOTE: This adjustment should be performed after WhiteBalance adjustment.

1) Input FUBK pattern to Antenna jack.2) Select S-BRI of SVC-3 mode.3) Press VOL F/G until (a) and (b) of FUBK are distinct and

press VOL G twice more.

: OPTION Adjustment (SVC MODE:OPTION-1,OPTION-2)

NOTE: When the EEPROM has been replaced, the Optiondata should be restored as the function of individualsystem and specification.

1) Press OK buttons on both TV set and Remote Controller atthe same time to get into SVC mode.

2) Press the Yellow button several times to find OPTION-1 orOPTION-2.

3) Input the correspond OPTION data referring to Table belowwith the numeric buttons 0~9.
