[+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.)

indicated by the arrow a.

2 Using a thumb pull up the rubber cap firmly in the direc-

tion 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.
