SELF DIAGNOSTIC

Numeral "0" means that no fault was detected.

Numeral "1" means the number of a fault occurrence (1~255).

STANDBY/indicator

– 5 –

Since the diagnosis results displayed on the screen are not automatically cleared, always check the self-diagnostic screen
during repairs. When you have completed the repairs, clear the result display to "0".

Unless the result display is cleared to "0", the self-diagnosis function will not be able to detect subsequent faults after
completion of the repairs.

[Clearing the result display]
To clear the result display to "0", press buttons on the remote commander sequentially when the self-diagnostic screen is
displayed, as shown below:

Channel [8]

/ "0"

[Quitting Self-diagnostic screen]
To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.

[+B overcurrent OCP ]

Occurs when an overcurrent on the +B (135V) line is detected by pin 97 of IC001
(A Board). If the voltage of pin 97 of IC001 (A Board) is less than 1V when V.SYNC is
more than HV, the unit will automatically go to standby.

[I-Port]

Occurs when an absence of the vertical deflection pulse is detected by pin 116 of
IC001 (A Board).

[IK $AKB%]

If the RGB levels* do not balance within 15 sec after the power is turned on, this error
will be detected by IC001 (A Board). TV will stay on, and indicalor will start to Blink 5
times.

[HV Protect]

Occurs when IC001 internal HV protect detects an abnormal. H-Pulse (frequency) due
to unproper power supply to IC001. TV cuts off high voltage power of anode CRT. No
picture will be detected eg IC607, IC604 go faulty.

* (Refers to the RGB levels of the AKB detection Ref pulse that detects 1K)
