MC-049A Adjustment Spec

NTV Development Group

1.Scope

These adjustment instructions are applied to MC-049A chassis.

2. Notes

2.1. Because this is a cold chassis, it is not necessary to use an
isolation transformer.

But, operate it using a transformer between the power supply line
and chassis

input to prevent electric shock and to protect the test
instrument.

2.2. All adjustments must be done in correct sequence.

However, for the better productivity, it can be changed in
pre-permitted range.

2.3. Environment conditions : If not specified, it must be done in
following conditions.

1) temperature : 25? ? 5?

2) Humidity : 65% ? 10%



2.4. Power supply of a SET which is adjusted is (100~240V)?10% AC,
50~60Hz



2.5. If not specified, the receiver must be operated for more than 20
minutes prior to

the adjustment.

2.6. Signal : Receive the standard color signal. (65dB?1dB uV)

LG standard signal means the digital pattern 13CH(480NC)

2.7. If not specified, APC ON is APC CLEAR.

3.1. Focus voltage adjustment

3.1.1. Receive the LG standard pattern(digital pattern, 480NC, 13CH).

3.1.2. Set the picture condition on 'APC CLEAR' mode.

3.1.3. Adjust the Focus volume of FBT for the best focus of horizontal
line A,

vertical line B.







3.2. Purity & Convergence adjustment

3.2.1. Purity adjustment

(1) Preparation

(1) Receive the RED Raster Pattern for purity adjustment.(11CH)

(2) Demagnetize the CPT and Cabinet with a degaussing coil.

(2) Adjustment

(1) Pre-adjust the static convergence(STC) with 4 and 6-pole
magnet.

(2) Push the DY(deflection Yoke) all the way to the CPT pannel.

(3) Turn the purity magnet(2-pole magnet) so that the 'green'
portion of left side

and the 'blue' portion of right side have same portion.

(4) Pull the DY slowly and fix it when the whole screen become
red.

3.2.2. Convergence adjustment

(1) Preparation

(1) Receive the Cross Hatch pattern for convergence
adjustment.(09CH)

(2) Let the contrast at the adequate luminance level.

(2) Adjustment

(1) Converge the RED vertical line and BLUE vertical line in the
same line by

changing the angle between the 2 tabs of the 4 pole magnet.

(2) Converge the RED horizontal line and BLUE horizontal line in
the same line by

turning the 2 tabs of the 4 pole magnet. This time, do not
change the angle

between the 2 tabs.

(3) Converge the R, G, B vertical line in the same line by
changing the angle between

the 2 tabs of the 6 pole magnet.

(4) Converge the R, G, B horizontal line in the same line by
turning the 2 tabs of

the 6 pole magnet. This time, do not change the angle between
the 2 tabs.

3.3. Screen voltage adjustment

3.3.1. Receive the NTSC or PAL-M/N signal into RF mode ( regardless of
channel.)

3.3.2. If you press the ADJ button in LINE SVC mode (IN-START button),
the LINE SVC

mode changes to screen adjustment mode.

3.3.3. Turn the Screen volume of FBT until the horizontal line is no
longer seen

and then stop.

3.3.4. Press the TV/AV button to exit SVC mode.

3.4. White Balance Adjustment

Prior to this adjustment, screen voltage adjustment must be finished.

3.4.1. Necessary Instrument

(1). White Pattern Generator (Can generate Low/High Light pattern)

(2). White Balance meter( CRT color Analyzer,CA-100)

(3). Factory Remote control

3.4.2. Preliminary steps

(1). Tune the TV set to receive an 100% white pattern.

(2). Perform screen adjustment first.

3.4.3. Adjustment

(1). Enter into adjustment mode by "INSTART" key and select
SERVICE1 mode.

(2). Adjust the item with CH+/- Key.

(3). Adjust the data with VOL+/- Key.

(4). Adjustment Procedure

Adjust"CONTRAST" and "BRIGHT" so that the bright level is
35Ft-L.

Select B DRIVE to adjust Y coordinate in High Light and select R DRIVE

to adjust X coordinate so that the color coordinates in High Light match
the values

In Table below.

Adjust 'CONTRAST" and "BRIGHT" so that the bright level is
4.5Ft-L.

Select B CUT to adjust Y coordinate in Low Light and select R CUT

to adjust X coordinate so that the color coordinate in Low light match
the values in

Table below.

Repeat (1) ~ (4) until the color coordinates in High and Low color
satisfies the Table.

Check the adjusted color coordinates with the white balance meter

Store the W/B adjustment data in EEPROM by using ENTER button before
EXIT.

13CH)

* Note : First, adjust deflection at 50Hz of PAL signal.

Then, adjust deflection at 60Hz of NTSC signal.

Store the deflection adjustment data in EEPROM by using
ENTER button.

Press Exit button to exit SVC mode.

(1) VL (Vertical Linearity)

Adjust so that the boundary line between upper and lower half
is in accord with geometric

horizontal center of the CPT.

(2) VA (Vertical Amplitude)

Adjust so that the circle of a digital circle pattern may be
located within the effective

screen of the CPT.

(3) SC (Vertical S-Correction)

Adjust so that all distance between each horizontal lines are
to be the same.

* Recommend initial setting data.

(4) VS (Vertical Shift)

Adjust so that the horizontal center line of a digital circle
pattern is in accord with

geometric horizontal center of the CPT.

(5) HS (Horizontal Shift)

Adjust so that the vertical center line of a digital circle
pattern is in accord with

geometric vertical center of the CPT.

(6) EW (Horizontal Width)

Adjust to that a digital circle pattern looks like exact
circle.

(7) ET (East-west Trapezium)

Adjust to make the length of top horizontal line same with it
of the bottom horizontal line.

(8) EP (East-west Parabolar)

Adjust so that middle portion of the outermost left and right
vertical line looks like parallel

with vertical lines of the CPT.

(9) CRNU (Upper Coner )

Adjust until symmetrize upper coner of the screen.

(10) CRNL (Lower Coner)

Adjust until symmetrize upper coner of the screen.

(11) BOW

Adjust the left and right crooked line on upper and lower side.


(12) ANGLE

Adjust the vertical slope.

(13) CRNU6

More deatail adjust until symmetrize upper coner of the screen.

(14) CRNL6

More deatail adjust until symmetrize Lower coner of the screen.

(13) PIP H (PIP H position)
