3.
Remove the PCB holding the LCD screen and metal shield
4.
Remove the metal shield by carefully bending the retaining lugs (see Figure 29)
5.
Very carefully flip the exposed LCD over to one side so it is off the PCB. It will still
be attached to the PCB by a short ribbon cable at one end, be extremely careful not
to damage this cable (see Figure 29).
6.
Disconnect the short ribbon cable and replace the LCD.
7.
Reassemble the LCD Assembly being careful to ensure a good contact between
LCD and PCB contacts (Lines will appear on your LCD if a bad contact is made)
8.
Reassemble your transmitter enough to test the new LCD. Do not fully reassemble
as it is likely that you may have a bad contact in the LCD (see above).
9.
If everything is working fine, clean the LCD with a soft cloth to remove finger marks
and then fully reassemble the transmitter. Reassembly is a reversal of disassembly.

with an in-built PCB and 0.1" single row receptacle connector (PCB header style) that
