Application and Installation
This LCD contact strip is a specialized component that provides the electrical interface between the radio's control circuitry and the LCD display panel. Using conductive elastomer technology, the strip allows for reliable electrical connections without requiring fragile soldered wires directly to the LCD glass. The strip contains multiple parallel conductive traces arranged to match the pin layout of the display, carrying signals for segment control, power supply, ground connections, and backlight operation.
Over time, LCD contact strips can develop problems due to contamination from dust, oils, or fingerprints, loss of elasticity that reduces contact pressure, degradation of the conductive material from age or temperature cycling, or physical damage during previous service attempts. Symptoms of a failing contact strip include missing or intermittent display segments, dim or flickering backlight, partial display operation, ghosting of characters, or complete display failure. Because the strip relies entirely on compression for electrical contact, even minor contamination or slight loss of compression can cause significant display problems.
Replacement requires complete disassembly of the radio housing to access the LCD display assembly. The radio must be powered off and all batteries removed before beginning work. The display module is typically held in place by small screws or clips that must be carefully removed. Once the mounting hardware is released, the compression holding the contact strip is relieved, allowing removal of the old strip.
Critical preparation steps include thoroughly cleaning both the LCD connector pins and the circuit board contact pads with isopropyl alcohol and a lint-free cloth or swab. All contamination must be removed to ensure proper electrical contact. The new contact strip must be positioned with extreme precision, ensuring all conductive traces align perfectly with their corresponding LCD pins and circuit board pads. Misalignment will result in incorrect or non-functional display operation.
When reassembling, mounting screws should be tightened in a cross-pattern sequence to ensure even compression distribution across the entire length of the contact strip. Torque must be sufficient to create reliable compression without over-tightening, which could damage the delicate LCD glass, crack the circuit board, or deform the contact strip. After reassembly, all display functions should be thoroughly tested, including all segments, characters, icons, and backlight operation, before completing final assembly.
This component is essential for radio service centers and technicians performing display-related repairs. Proper installation requires patience, precision, and attention to cleanliness to ensure reliable long-term display operation.
