[+B overcurrent $OCP%]

Occurs when an overcurrent on the +B(135V) line is detected by pin 32 of IC001 (A board).
If the voltage of pin 32 of IC001 (A board) is more than 4V, the unit will automatically go to
standby.

[V-PROTECT]

Occurs when an absence of the vertical deflection pulse is detected by pin 13 of IC001
(A board).

[IK $AKB%]

If the RGB levels* do not balance within 15 sec after the power is turned on, this error will be
detected by IC001 (A board). TV will stay on, but there will be 5 times LED blinking.

Occurs when IC001 internal HV protect detects an abnormal H-Pulse (frequency) due to
improper power supply to IC001. TV cuts off high voltage power of anode CRT. No picture will be
detected. eg: IC602, IC604 go faulty.

* (Refers to the RGB levels of the AKB detection Ref pulse that detects IK.)

• After removing the anode, short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield or

carbon paint on the CRT.

•

1 Turn up one side of the rubber cap in the direction

indicated by the arrow a.

2 Using a thumb pull up the rubber cap firmly in the direction

indicated by the arrow b.

3 When one side of the rubber cap is separated from the

anode button,  the anode-cap can be removed by turning
up the rubber cap and pulling it up in the direction of the
arrow c.

•

1 Do not damage the surface of anode-caps with sharp

2 Do not press the rubber too hard so as not to damage

3 Do not turn the foot of rubber over too hard.

• Please make sure the TV set is not in standing position before removing necessary CRT support located on bottom right

and left.

1) Remove the Rear Cover.
2) Unplug all interconnecting leads from the Deflection Yoke, Neck Assy, Degaussing Coils and CRT grounding strap. Remove

Chassis Assy.

3) Place the TV set with the CRT face down on a cushion (jig).

CAUTION :
1. Make sure wires are kept away from sharp

edges, heatsinks & high temperature parts.

2. Do not over pull the wires during dressing

--> avoid disconnection of wires.

3. Prevent wires from being sandwiched with

beznet's front terminal when docking chassis.

4. Prevent tie, cable from touching rear cover

or any enclosures by turning them away
from it --> to avoid rattle sound & prevent
cable tie from touching solder side of board.

Dress & control mounted wires (Lead Assy, G2 & 200V wire) on CV board if necessary : 
--> ensure wires do not get trapped during solder DIP process 
--> ensure wires do not get punched by ICT jig (modify ICT jig if applicable)

Ensure Lead Assy, G2 is kept away from leg of nearby 
conductive parts during solder DIP process
--> to ensure insulation of wire does not get melted when 
touching leg of part due to heat conduction from solder bath.
