Self-diagnostic indication
When something abnormal occurs with the monitor, this function informs you of the condition of the monitor with
the self-diagnostic lamps, allowing for smooth service work.
If the monitor screen turns off and the self-diagnostic
lamps light or flash
If the self-diagnostic lamps light or flash in red, check the
following before consulting the dealer where you purchased
the monitor.
• If the self-diagnostic lamp 1 (upper) flashes, lamp 2
(middle) lights, and lamp 3 (lower) flashes
This may be caused by the dusty intakes on the rear. If this
happens, switch off the main power using the POWER
switch (set to “
‡
(off )”), unplug the AC power cord, then
clean the intakes by referring to the instruction on page 3.
After cleaning, switch on the monitor’s main power again.
If the self-diagnostic lamps do not go off, consult your
dealer immediately.
If the monitor screen dims a little and “TEMP. OVER”
appears (or flashes)
If “TEMP. OVER” appears or flashes at the right bottom of the
screen, check the following before consulting the dealer
where you purchased the monitor.
“TEMP. OVER” appears to warn you of internal heat buildup,
which is usually caused by accumulated dust around the
intakes or by improper installation. If the cause of the
internal heat buildup is eliminated, this indication disappears
and the screen returns to normal brightness.
• If “TEMP. OVER” flashes in yellow
This may be caused by the dusty intakes on the rear. If this
happens, switch off the main power using the POWER
switch (set to “
‡
(off )”), unplug the AC power cord, then
clean the intakes by referring to the instruction on page 3.
– After cleaning, switch on the monitor’s main power
again. If “TEMP. OVER” still flashes, this problem may
be caused by improper installation or improper
location of the monitor. In this case, consult your dealer
immediately to solve this improper installation and to
improve the circumstances around the monitor.
• If “TEMP. OVER” appears in red
“TEMP. OVER” will be shown for about two minutes,
the monitor will shut off automatically, then the self-
diagnostic lamps light in red. If this happens, switch off
the main power using the POWER switch (set to “
‡
(off )”),
unplug the AC power cord, then consult your dealer
immediately.
If the trouble still persists, follow the procedure
below:
1 Check which lamps are lit or flashing.
On the Self-diagnostic Report Sheet (below),
check the box next to “Lights” or “Flashes” of the
corresponding lamp or lamps.
• Only one lamp may light or flash, or all three lamps
may do so.
2 Switch off the POWER switch on the back of
the monitor.
3 Unplug the power cord.
4 Call your dealer and tell them which lamps
are lit or flashing. (Copy and fax the Self-
diagnostic Report Sheet below.)
NOTE
• If you switch on the main power immediately after switching it
off (or after recovering from a brief power interruption), the self-
diagnostic lamps may light (or flash), and no image may appear
on the screen. In this case, switch off the main power again, wait
for about 10 seconds, then switch it on again. If no self-diagnostic
lamps light or flash, you can operate and use the monitor as
usual.
