Precautions on Safety for Replacement of Backlight
• High voltage is generated in the inverter when the power is supplied to the system. To avoid an electric
shock, reconfirm that the power switch is set to OFF before starting operation.
• The fluorescent tube and high-voltage parts have high temperature immediately after the power
switch of the main unit is set to OFF. To avoid burning your hand or similar accidents, wait awhile after
turning the power to OFF, then start operation.
• High voltage may be charged to the inverter immediately after the power switch of the main unit is set
to OFF. Wait awhile after turning the power to OFF, then start operation.
• In some cases, the fluorescent tube of backlight may be damaged. Take adequate caution for injury
during operation.
