2-2 Explanation of Landing Compensation Circuit
2-2-1 Definition
Landing in the display media using CRT means operation that beam occurred at the electronic gun passes
through a constant hole and arrives to the light emitting object. The more accurate this is, the more even
unified brightness of the whole of screen is uniform. However, landing becomes loose since there is devia-
tion of manufacturing process in the CRT itself and various inside/outside factors.
- Effect of earth magnetic field
There is a magnetic line of force proceeding from South to North in the earth, called as earth magnetic field.
CRT emits light by electron from an electronic gun and direction of this electron becomes reverse direction
of current. Force (F) applies to electron moved by current (I) of the earth magnetic field and the CPT.
Electronic beam fails to arrive a proper position due to this force, which must constantly arrive at the fixed
position of a shadow mask.
- Effect of ambient temperature
Beam flying to a constant position fails to arrive to the light emitting object by distortion of a mask since
thermal expansion shrinkage of the shadow mask made of metal is different from the side where the light
emitting object is attached depending on temperature.
- Effect of operation time and beam force
Immediately after TV turns on, temperature inside of the CRT rapidly increases by electronic beam and
thereby thermal expansion proceeds in the shadow mask. This proceeds for about 2 hours and accordingly
landing varies. Such a level of change differs depending on the strength of beam shone on the screen
together with time. The stronger strength of the beam is, namely the brighter the screen is, the severer
change of landing is.
The CRT used in the ZEUS is OMEGA CRT of a complete flat32" HD-class with an injection degree of max-
imum 120' independently developed and produced by the SDI. It was manufactured in the most minimum
width in the world in comparison with the same size to reduce depth of the set.
Such configuration gives a bad effect on the landing surface and thus landing at the 4 point within the CRT
becomes distorted even by a small ambient effect and purity error (change of color purity: other color)
occurs.

** The above tables show direction of actual effect and a reverse direction of it for Landing Data
(direction of microscope). **
The earth magnetic field sensor and the temperature sensor are attached for measuring direction and
strength of the current earth magnetic field and temperature of set. Since effect on the above table must be
compensated, force in the reverse direction must be made.
The following figure shows that coil for landing compensation and coil for TILT compensation are attached
on the rear side of CRT to compensate for it. 4 round coils (coil for landing compensation) is used to com-
pensate for error in the corner where landing error mostly occurs. The TILT coil adjusts degree of the
whole of screen.

Reference Information
2-2-3 Operation of Circuit
- Explanation of Operation
Operation of the landing compensation circuit is controlled by a sub-micom within module. Operation of
the sub-micom for the actual landing compensation is perceived and controlled. It receives values of the
earth magnetic field sensor (SEN01) and temperature sensor (DM01) via the A/D port of the sub-micom
and then perceives the current status and outputs compensation value in the PWM form. Direct driving of
the landing compensation coil is done at the LA6510 power drive OP AMP. Standard operation voltage of
the AMP is made by divided voltage of R028, R029 and applied to the (+) 1N of the OP AMP. The PWM
type of control data that is output from the MICOM is smoothed by the RC integrated circuit and becomes
analog voltage with a constant level. It is applied to the reverse amplitude circuit composed of a power
drive OP AMP via a TR and resistance. In this case, amplitude level is determined by the whole output
impedance and feedback resistance of circuits connected to the (-) 1N terminal of the OP AMP. The LA6510
VSENSE PORT is used for limiting current and can limit the max current value using resistance value
between VOUT terminals. The output flows through the LC coil and creates magnetic field. Position of
electronic beam is compensated by the magnetic field. DC R (voltage at both ends of the LC coil measured
by DVM as direct current resistance component) of the LC coil is about 100 ohm.
Details of explanation are deleted since operation of the tilt coil operates even in general TV.
- Inspection of Operation
Operation inspection after set repair is as follows:
1) Is the output terminal (red, gray, blue, black) of coil at the aging mode within 9 +/- 300mV?
2) Does other color occur when removing the PCB Front Connector(CN905A) from the Main Chassis?
3) Does other color occur when touching magnetic object near the earth magnetic field Sensor Module?
Where all answers for the above questions are Yes, they show that the Landing compensation circuit
properly operates for the set.
2-2-4. Related OSD Matters
Two matters are related each other in the factory mode.
Factory mode -> TL, BL, TR and BR value are value of the area that user (service man) can vary.
It is better not use these values unless purity error occurs (where, TL, BL, TR, BR represents TOP LEFT,
BOTTOM LEFT, TOP RIGHT and BOTTOM LIGHT, respectively).
Factory mode -> There are TL, BL, TR, BR and SENCE LRR types in the ITC. They must not be changed.
There is information about CRT and the circuit part for compensating it. However, in replacing EEPROM
or main chassis, change of it is needed but the value of sense REF must not be changed.
(The sense REF is used to compensate for sensor unique omission and is line adjustment value that reads
center value of sensor in the 0-earth magnetic field and stores it at the EEPROM. Since the 0-earth magnetic
field cannot be made in the field, this item shall not be changed. If changing it and thus purity error occurs,
the EEPROM must be replaced according to the following cautions)
Samsung Electronics 2-5
Reference Information
2-2-5 Cautions in troubleshooting
Check item prior to repair
1) Is the +- output terminal (Red, Gray, Blue, Black) of a coil in the Aging Mode within 0 +/- 300mV?
2) Does other color occur when removing the PCB front connector from the main chassis?
3) Does other color occur when touching approaching magnetic object around the earth magnetic field
Sensor Module?
If all answers for above questions is Yes, it means landing compensation circuits properly operates for the
set.
1) Cautions in replacement of parts and E2PROM in earth magnetic field
You should replace an E2PROM within the main chassis and the main chassis in the following orders if
necessary:
Where set operation is possible
a) Memorize values of TL, BL, TR and BR from the Factory Mode -> TIC. Sense REF values should not be
changed at any case (If pressing + - key, current values of the earth magnetic field becomes standard
value and emergent operation is done by it).
b) Replace parts.
c) Change it into TL, BL, TR and BR memorized from the Factory Mode -> TIC. Sense REF values should
not be changed at any case (In this case, initial value is 115, 125).
d) Inspect operation status.
e) If there is no abnormality in the operation inspection but other color occurs, change and adjust
four value(TR, BL, TR, BR) from the Factory Mode ->User so that there is no purity error.
Where set operation is not possible
a) Replace parts.
b) Change should not be done at any case in the Factory Mode -> TIC mode.
(In this case, initial value is 115, 125).
c) Inspect operation status.
d) If there is no abnormality in the operation inspection but other color occurs depending on ambient
conditions, change and adjust 4 values from the Factory Mode User so that there is no purity error.

2) Cautions in De-Gaussing
1. ADG (Auto Degaussing)
- There is no problem since set itself operates in the Degaussing operation of set itself under the Purity
Off Mode.
However, the set normally operates when performing Power On after Off for 30 minutes after removing
power.
2. HDG (Hand Degaussing)
- If desiring to operate the compulsory Degaussing mode, you should set "Aging Mode" for operation.
3. AGING MODE
- A strong magnetic field occurred in the HDE-GAUSSING affects on sensor in the earth magnetic field
and as a result, a strong magnetic field occurs from the LC coil. It is not good for sense operation and
DE-GAUSSING of the earth magnetic field. Be sure to perform semsing and DE-GAUSSING magnetic

Usually, a color TV needs only slight touch-up adjustment upon installation. Check the basic
characteristics such as vertical size, horizontal size, and focus. Observe the picture and check for
good black and white details. There must be no objectionable color shading: If color shading is

The PWM duty which is outputed from HVQ01 is variable according to Beam current of high voltage.
In case high voltage goes up (or down) due to change of Beam Current, PWM duty will be decreased
(or increased).
This pulse which is inputed to QH406 Gate(FBT) will be turn on between source and drain,
and IC current of QH405 will be flow to primary of storage trans (TD402S) and then will be charge energy
in primary of storage trans during trace period .
This energy is variable according to pluse duty, and will be inducted to secondary of TD402S.
The inducted energy will be added to basic high voltage generation pulse in FBT (T444S).
As a result, high voltage will be regulated by this method.

Note2. HOLD-DOWN OR SAFETY CIRCUIT INFORMATION : 29", 34"
The high voltage hold-down circuit prevent TV from damage caused by abnormal high voltage.
The high voltage hold-down circuit is implemented by detecting the variation of Heater voltage because
heater voltage varies with the variation of high voltage.
When the input voltage (A-Point) of QX01's RESET IC is higher than 4.5V, MICOM #3 port is turned to
"HIGH" then power-off follows.
So to speak, if MICOM #3 port becomes "HIGH", MICOM #1 port is controlled (from "HIGH" to " LOW")
and power-off is implememted.
