KV-27FV310/29FV310/32FV310/36FV310
+B overcurrent (OCP)
Occurs when an overcurrent on the +B (135V) line is detected by pin 48 of IC001 (A Board). If the voltage of pin 48 of IC001 (A Board) is less than 1V
when V.SYNC is more than seven verticals in a period, the unit will automatically turn off.
+B over voltage (OVP)
Occurs when a high is felt on pin 2 of IC501 (A Board).
V-STOP
Occurs when an absence of the vertical defl ection pulse is detected by pin 31 of IC301 (A Board). Power supply will shut down when waveform interval
exceeds 2 seconds.
IK (AKB)
If the RGB levels* do not balance within 2 seconds after the power is turned on, this error will be detected by IC301 (A Board). TV will stay on, but
there will be no picture.
*(Refers to the RGB levels of the AKB detection Ref pulse that detects 1K).
Zero Cross
Check Q691 collector (GK Board) 7.5V STBY goes to 0V when the set is turned on.
9V Check
Check Q691 collector (GK Board) 7.5V STBY goes to 0V when the set is turned on.
