Self-diagnostic Indication

The screen monitor may automatically turn off and self-diagnostic lamps next to the power lamp may light or flash.
When something abnormal occurs with the Monitor, this function informs you of the condition of the Monitor with self-
diagnostic lamps, allowing for smooth service work.
If the self-diagnostic lamps glow or flash in red, use the following procedure before consulting the dealer where you purchased
the Monitor.

Check which lamps are lighting or flashing.
On the Self-diagnostic Report Sheet (below), check the box next to "Lights" or "Flashes" of the corresponding lamp or
lamps.

Call your dealer and tell which lamps are lighting or flashing. (Copy and fax the Self-

Note:
• If you turn on the Monitor soon after turning 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, turn off the Monitor again, wait for about 10
seconds, then turn it on again. If no self-diagnostic lamps light or flash, you can operate and use the Monitor as usual.
