Troubleshooting
If you think the monitor may be faulty, please check the following points before taking it to be repaired.

nearest Sharp authorized Service Center.
The monitor's fluorescent tubes have a limited life span.
- If the screen darkens, persistently flickers or does not light up, it may be necessary to replace the
fluorescent tube unit. Please inquire at the shop where you purchased the monitor or your nearest
Sharp authorized Service Center. (Never attempt this replacement on your own.)

again.
