Removing the Sensor
CAUTION
To reduce the risk of glass breakage which may result in minor or moderate
injury:
Do not try to pry the sensor off the LCD if you need to remove the sensor for servicing.
You may break the glass and injure yourself or others.
If you need to remove the sensor, use a razor knife or a single-edge razor blade to
carefully cut through the mounting tape.
•
Start at the top of the sensor and work down the sides.
•
Be careful not to scratch the display or the sensor.
•
Be sure to support the sensor as it comes away from the display.
•
Be sure not to knock off components as you approach the corners
Use isopropyl alcohol to remove the foam tape and adhesive residue from the back of
the sensor. Be careful not to damage any silver printing or components. Be sure to
follow solvent manufacturer's precautions and directions for use when using any
solvents. Follow manufacturer’s directions for suitable chemicals for your display.
Repeat the procedure for properly attaching the sensor to the display.
Adding a Sealing Gasket to the Bezel
1.
Place the bezel face down on an anti-static pad.
2.
Cut strips of the closed cell, compressible foam sealing gasket tape (3M 4508) to fit
the inside edges of the bezel opening to form a full perimeter seal. To ensure tight
fitting sealing joints, the gasket tape should be cut using a razor knife or single-edge
razor blade.
3.
Remove the backing material from the tape. Adhere a strip of gasket tape to each
inside edge of the bezel opening. Align one edge of the gasket to the edge of the
bezel opening. If the gasket overlaps the bezel edge, it will be visible from the front
of the display. If the gasket is spaced away from the bezel edge, you will create a gap
that can collect dust, liquids, etc.
4.
Pay close attention to the bottom edge joints. Butt the gasket tape edges to create a
tight fitting joint.
