5. MAINTENANCE
Panel
Take care not to damage or scratch the panel. Clean with a soft
woolen or cotton towel. Use a watery solution or a mild commercial
glass-cleaning product.
Cabinet
Do not use chemical cleaning products, benzene, toluene, xylene or
other solvents. Clean with a soft cloth dampened with mild detergent
and water. Repeat with water only and wipe dry with a dry cloth.
Removing dust from the rear of the glass panel
It may be possible that dust particles have entered the display and are
stuck to the rear of the glass.
We recommend to let this cleaning procedure be done in a BARCO
service center.
However, when really necessary, you can perform the cleaning on site
if you can work in conditions that are as clean and dust-free as
possible. This is to avoid more dust entering the display when opening
it.
To remove the glass panel:
1 Switch off the display.
2 Tilt the panel.
3 Unscrew the 4 sunken screws at the rear, fixing
the glass panel and bezel.
4 Remove the bezel with glass panel.
Cleaning instructions:
- Dust, fingerprints, grease etc. can be removed by using a soft
damp cloth (a small amount of mild detergent can be used on the
cloth, NOT solvent).
- Do not apply liquid directly to the LCD surface as excess liquid
may cause damage to internal electronics.
- Take care not to touch the I-guard light sensor on the LCD panel.
