[+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.
If the voltage of pin 32 of IC001 (A board) is more than 4V, the unit will automatically go
to standby.

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.
