3.1 Memory Initialization

If a service repair is undertaken where it has been required to change the MEMORY IC (IC101 and

IC10 ) the following steps should be taken to ensure correct data settings: " memory initialization":

• Unplug the power cord from the AC Power Source;

• While holding down “MENU” button and “VOLUME –“ button (front panel), plug the power cord in

the AC Power Source (wait seconds before release the buttons).

• Turn on the TV set through front panel “POWER” button or remote control.

• To certify that the initialization was success executed, it will appear the following message:

3.4 AGC Adjustment

• Apply a color bar pattern (RF Input) with 500µV signal;

• Connect a DC Voltmeter, in the AGC pin of the tuner;

• Adjust AGCT to Zero and measure the voltage (V1);

• Adjust AGCT so that the indication on the voltmeter be (V1) - 1 ± 0. V.

3.5 Stereo Adjustment

• For the adjustments, proceed according to illustration ;

• Adjust output indicated by “A” to tension equal to half of VCC plus 1V ;

• Adjust TC to an indication in the microAmpère meter of 4µA in the pin 17 of IC450;

• Apply 300Hz/Mono/ 5KHz of deviation, 50mVrms, in the pin 9 of IC450;

• Adjust SL to 500± 0mVrms in the pins 15 and 38 of IC450;

• Apply in the channel L=300Hz and in the channel R= 3k, 14% of generator Stereo modulation

DBX-NR (EIDEN BTSC );

• Change ADJ from 0 to 1. Check A1 and A2 after 1 second (if they varied);

• After 1 second returns ADJ to 0 . The stereo circuit will align automatically.

3.6 Vertical Adjustment

• Apply a circle Pattern Philips signal (RF Input)

• Using the remote control, set the MAGIC mode “ORIGINAL”

• Activate the adjustment mode display (SBL item). Ajust SBL from 0 to 1. Blanking the bottom of

the screen.

• Adjust VSH until the bottom of the pattern be aligned with the reference marks of the mechanical

center on picture tube (the central vertical line in the center of the tube).

• Adjust VS until the central line be aligned with the half bottom of the screen (the central line of the

circle pattern in the half cut of the screen)

• Return SBL from 1 to 0 value . The image could be compressed or expanded.

• Select VA item and set its value to adjust the size of the picture (proportional height and width

picture).

• If necessary readjust SC item and set its value to adjust the Linearity (acts in the top of the image)

and VA.

NOTE: The SC and VA adjustments are interdependent (they should be used together).

When the image to be decentralized in the vertical, to retouch VSH and/or VS

3.7 Horizontal Adjustment

• Apply a Circle Pattern Philips (RF Input)

• Using the remote control, set the MAGIC mode “ORIGINAL”

• Activate the adjustment mode display (HSH item). Select HSH item and set its value to adjust the

horizontal symmetry of the pattern;

• Select HP and HB items and adjust its value if necessary.

3.8 MAGIC Adjustment

• Adjustment of original magic should have been according to pattern

• Receive the color bar pattern (NTSC signal, RF input)

• Connect the oscilloscope probe to the collector of Q830 (cathode G)

• Using the remote control, set the image controls as follow:

Brightness: adjust to central position (8 Bars)

Contrast: adjust from maximum to minimum (4 Bars)

Color: adjust from minimum to maximum (5 Bars)

Sharpness: adjust from minimum to maximum (3 Bars)

Tint: adjust to the center (8 Bars)

• After the image menu preset, turn off the television and activate the service menu. Select

ORIGMAG item;

• Press “VOLUME +” button and change the value from 0 to 1. Turn off the television and the

ORIGINAL MAGIC setup will be registered.

3.9 “SCREEN ( G2 )” Adjustment

• Apply a Circle Pattern Philips at the antenna terminal (RF Input).

• Using the remote control, set the brightness control to 10 Bars of the bargraph.

• Activate the service mode and select BLKCURR item (the menu value should be 0)

• Turn the Screen Grid Potentiometer (fly back body) fully counterclockwise (minimum adjustment).

• Press the “VOLUME +” button . The register will change to 1 and vertical Deflection will be

blanked.

• Turn the Screen Grid Potentiometer slowly clockwise until the power led (stand by) turn on (if the

adjustment of the screen Grid Potentiometer is turned beyond the ideal point, the power led will be

turn off)

• Press the “VOLUME +” button, it should return the original BLKCURR value. The image will be

return and the adjustment is finished.

3.10 “FOCUS” Adjustment

• Apply a Circle Pattern Philips at the antenna terminal (RF Input).

• Using the remote control, set the Magic mode “ORIGINAL”
