[+B overcurrent OCP ]
Occurs when an overcurrent on the +B(135) line is detected by Q6804.
[High voltage protector of Horizontal Deflection]
If Q6804 go to ON, the voltage to the pin57 of IC4301 go to "HIGH".
The unit will automatically turn off.
Occurs when an overvoltage of horizontal pulse is detected by D6809.
If the voltage of anode D6809, Q6814 and D6808 goes to High, the voltage
to pin57 of IC4301 go to "HIGH".
The unit will automatically turn off.
The unit will automatically turn off.
Occurs when an overvoltage of horizontal pulse is detected by D6809.
If the voltage of anode D6809, Q6814 and D6808 goes to High, the voltage
to pin57 of IC4301 go to "HIGH".
The unit will automatically turn off.
[+B overvoltage OVP ]
Occurs when an overvoltage on the +B(135) line is detected by D6635 and
Q6606. If Q6606 go to ON, the voltage to pin2 of IC001 go to "HIGH". The
unit will automatically turn off.
Q6606. If Q6606 go to ON, the voltage to pin2 of IC001 go to "HIGH". The
unit will automatically turn off.
[Vertical deflection failure]
Occurs when an absence of the vertical deflection pulse is detected by
Q6808. Shut down the power supply.
Q6808. 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.
error will be detected by IC4301.
TV will stay on, but there will be no picture.
[5V/9V failure]
Occurs when 5V/9V is not supplied to Micon (IC001).
No raster will be detected or no picture.
