3. STOPPING THE STANDBY/TIMER FLASH
Turn off the power switch on the TV main unit or unplug the power cord from the outlet to stop the STANDBY/TIMER lamp from flashing.
4. SELF-DIAGNOSTIC SCREEN DISPLAY
For errors with symptoms such as "power sometimes shuts off" or "screen sometimes goes out" that cannot be confirmed, it is possible to bring up
past occurrences of failure for confirmation on the screen:
[To Bring Up Screen Test]
In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:
Screen display / Channel 5 / Sound volume – / Power ON
˘
Note that this differs from entering the service mode (sound volume + ).
Self-Diagnostic screen display:
SELF DIAGNOSTIC
2: 0 <-------------Numeral "0" means that no fault has been detected.
3: N/A 0
4: 0
5: 1 <-------------Numeral "1" means a fault has been detected one time only.
101: N/A 0
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-diagnostic 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 as shown below when the diagnostic screen is being
displayed.
Channel 8 / ENTER
[Quitting Self-diagnostic screen]
To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.

3-2. CONVERGENCE
Preparation:
• Before starting, perform FOCUS, V. LIN and V. SIZE
adjustments.
• Set BRIGHTNESS control to minimum.
• Feed in dot pattern.

If the blue dot does not converge with red and green dots, perform
the following steps:
• Move BMC magnet (a) to correct insufficient H. Static conver-
gence.
• Rotate BMC magnet (b) to correct insufficient V. Static conver-
gence.
In either case, repeat Beam Landing Adjustment.

Tilt the V. STAT magnet and adjust static convergence to open or
close the V. STAT magnet.

( 2 ) Dynamic Convergence Adjustment
Preparation:
• Before starting, perform Horizontal and Vertical Static
Convergence Adjustment.
