STANDBY u indicator

3. STOPPING THE

STANDBY (1) INDICATOR FLASH

Turn off the power switch on the TV main unit or unplug the power cord from the outlet to stop the STANDBY (1) indicator from flashing.

4. SELF-DIAGNOSTIC SCREEN DISPLAY

For errors with symptoms such as "power sometimes shuts off" or "screen sometimes goes off" that cannot be confirmed, it is possible to bring up past occurrences of failure on the screen for confirmation.

[To Bring Up Screen Test]

In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:

Display

/ Channel 5 / Volume / Power / TV

˘

Note that this differs from entering the service mode (volume [+]).

The following screen will be displayed indicating the error count.

ERROR MENU

2 : 0 3 : N/A 4 : 0 5 : 1 8 : 0

101 : N/A

Numeral "0" means that no fault was detected. Numeral "1" means the number of a fault occurrence (1 ~ 255).

5. HANDLING OF SELF-DIAGNOSTIC SCREEN DISPLAY

Since the diagnostic 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 subsequent as shown below when the self-diagnostic screen is being displayed.

8 / -

[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 32 of IC001 (A board).

If the voltage of pin 32 of IC001 (A board) is more than 4V, the unit will automatically go to standby.

[V-PROTECT] Occurs when an absence of the vertical deflection pulse is detected by pin 13 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, but there will be 5 times LED blinking.

[HV PROTECT] Occurs when IC001 internal HV protect detects an abnormal H-Pulse (frequency) due to

improper power supply to IC001. TV cuts off high voltage power of anode CRT. No picture will be detected. eg: IC602, IC604 go faulty.

* (Refers to the RGB levels of the AKB detection Ref pulse that detects IK.)
