+B overcurrent (OCP)
Occurs when an overcurrent on the +B (135 V) line is detected by Q6303.
If Q6303 go to ON, the voltage to pin 3 of IC002 go to UP. The unit will
automatically turn off.
+B overvoltage (OVP)
Occurs when an overvoltage on the +B (135 V) line is detected by D6318.
If D6318 go to ON, then voltage to pin 6 of IC002 go to UP. The unit will
automatically turn off.
Vertical deflection failure
Occurs when an absence of the vertical deflection pulse is detected by
Q5302, Q5303, and D5303. Shut down the power supply.
White balance failure
If the RGB levels do not balance or become low level within 5 seconds. This
error will be detected by IC4301.
TV will stay on, but there will be no picture.
High voltage protector of Horizontal Deflection
Occurs when an overvoltage of horizontal pulse is detected by D5115 and
IC5201.
If the voltage of pin 1 of IC5201 goes to High, the voltage to pin 20 of IC4301
go to UP. The unit will automatically turn off.
Audio Protector
If the Audio out lines become DC.This error will be detected by Q1202,
Q1204 and Q1203.
The unit will automatically turn off.
