To repair the encoder of the Icom IC-718, follow the steps below: Icom IC-718 ремонт валкодера (encoder repair)

Make sure you have the necessary tools, such as screwdrivers, tweezers, and a soldering station. Turn off the device and disconnect it from the power outlet. Open the radio cabinet. This usually involves removing a few screws or latches. Locate the encoder, which is a circular component with a shaft in the center and electrical contacts around it. Disconnect the electrical wires connected to the encoder. Take note of their location and sequence so that you can reconnect them correctly after the repair. Carefully, using tweezers, remove the encoder from the radio. Inspect the encoder for any visible damage or wear. Check if the contacts are dirty or corroded. If the contacts are dirty, clean them with isopropyl alcohol and a soft brush or cotton swab. If the contacts are corroded, you can use fine sandpaper or a copper wire to clean them. Test the operation of the encoder by rotating it in different directions. Make sure it rotates smoothly without sticking. If a replacement encoder is needed, acquire a new original encoder from the manufacturer or a compatible substitute. Install the encoder back into the radio, following the reverse sequence of the steps described above. Reconnect the electrical wires to the encoder according to their correct positions. Close the radio cabinet and secure it with screws or latches. Connect the radio to a power source and check the operation of the encoder. Ensure that it rotates smoothly and without issues. If you encounter difficulties or lack experience in repairing radio equipment, it is recommended to seek a professional service center or a qualified technician to perform the repair.
