+B overcurrent (OCP)
Occurs when excessive current fl ows through R5013. The increase in voltage across R5013 causes the output of Q5004 to go high, and this high
signal goes to the micro.
+B overvoltage (OVP)
IC6505 dB OVP condition and turns on Q6522. This sends a high signal to the micro and also shuts down the AC relay.
V-STOP
Occurs when an absence of the vertical defl ection pulse is detected by pin 24 of IC2801 (BY Board). Power supply will shut down when waveform
interval exceeds 2 seconds.
White Balance Failure
If the RGB levels* do not balance within 2 seconds after the power is turned on, this error will be detected by IC2801. TV will stay on, but there will be
no picture.
*(Refers to the RGB levels of the AKB detection Ref pulse that detects 1K).
Low B OCP/OVP
Occurs when set 5V is out.
Horizontal Defl ection Stopped
Occurs when either:
1) a +B overcurrent is detected (IC5007), or
2) overheating is detected (Thermistor TH5002).
