Step 10
The display is kept in place by the handle (shown in
Step 9
) that is
marked
yellow
, only.
Don't press the handle with too much power. It
breakes very fast.
Push the handle leftwards (relative to the image
shown here) and lift up the display by pushing it up
with a finger (use the square opening).
Be careful with the Digitizer-Cable. The shape of
the cable makes it very fragile. If you lift up the display without care you
may probably tear the cable by accident.
Step 11
The wires for the backlight-foil are located at the position mar-
ked
yellow
. There's a little notch. Pull out the wires carefully
before going to the next sub-step.
Pull out the foil.
Do not touch or bend the green circuit board. Do not open
the latches which hold the board in place.
The connection to the display can be damaged in a manner
wich cannot be fixed or corrected easily.
The
blue
markings are only interesting in Step 14 when you put
the foil back in place.
Step 12
Cut the wires of the original foil close to the soldered connection. Shorten the
connection wires of the replacement foil to a length of about 5 millimeters.
The EL-sheet will be damaged if soldered too hot or too long. Be careful!
Unisolate the wire-ends for about 2 milimeters. Tin one of the two wires; keep
the tin fluid and make the connection with the connector of the replacement foil.
The connector is made of very thin copper which will heat up very fast.
For thermal compensation use the pliers and pick the connector where it comes
out of the lamination. This ensures, that most of the soldering-heat is guided
into the pliers instead of causing harm to the foil.
Continue with the second wire the same way. Don't care about the color of these
wires - it's not needed because the foil is driven by alternating current (ac).
Use some insulating tape to protect the contacts against short circuits.
