tip of a knife can be used to pierce the label to give you access to the screw. The socket on the screws
is a T6 or T7 Torx. Torx drivers are similar to Hex (Allen wrench) but have a star−like tip. Torx are
available at most hardware stores (or in gift tool sets that you never really looked at).
2. Remove the three screws and gently work the case apart. Mine hung up on the rubber block that is the
base for the five white push buttons. Be patient. Some of the components in the Pronto are sensitive to
Electro Static Discharge (ESD). Make sure you are grounded before touching the inside of the unit.
Use the same precautions that you would use to change out a board in your computer.
3. Now you have access to the Printed Circuit Board (PCB). Two more screws need to be removed to
separate the PCB from the case. Be careful here, there is a flat−cable (flex cable) that attaches the
screen to the PCB. Lay the PCB and the top case out so that you can unplug the cable from the PCB.
The connector on the PCB has two semicircular tabs on either side of the cable. With moderate
pressure, slide the two tabs away from the connector until they stop (about 2mm). The cable should
easily slide out now.
4. The screen is held in place with two more screws through a plastic support bezel. Remove the bezel
and screen. There are some small hook features in the bezel that hold the screen in place so you will
need to gently pop it out.
5. Now you are ready to reverse this process and reassemble your remote with a replacement screen. Be
sure the flat−cable is well seated in the PCB connector before sliding the two semicircular tabs back in
place. Make sure the cable is out of the way of the Left and Right buttons when you reassemble the
PCB to the case. Your may need to bend it into an "S" or "W" shape. You can practice with the old
screen if you like. Be careful to not over−tighten the screws during reassembly.
Note: depending on the screen model you receive, some small cuts may need to be made in the Pronto
case to clear newly arranged components on the LCD. A single edged razor or Exacto knife can be
used to make these cuts. Be sure everything clears the case before tightening all screws!
A6−07 Why does the screen's contrast keep changing?
On all black and white models, the LCD screen's contrast will become darker as the screen warms up,
either by using the remote or by external sources such as your hand. Although this can be annoying,
you may be able to find a contrast level that is acceptable for both "cold" and "warm" states.
