Using the parts list, identify the exact replacement. For example, “R23 – 10k ohm, 1%, 1/10W, 0402 SMD.” Order the part from an electronics distributor (Mouser, DigiKey). Carefully solder the new component (a microscope and fine-tip soldering iron are required).
Reverse the disassembly steps. Power on and test on several bands. Confirm the original problem is resolved. icom ic705 service manual
Before diving into the technical details, it is crucial to distinguish between the two primary documents available for the IC-705. Using the parts list, identify the exact replacement
Simply put: The owner’s manual tells you how to push the buttons. The service manual tells you why the button works and how to fix it when it doesn’t. Before diving into the technical details, it is
Owning the service manual is useless without proper tools. The IC-705 is not a 1970s tube rig. To work on it, you need:
If you lack these tools, even with the service manual, you will likely cause more damage than you fix.
This is one of the most valuable sections for repairs. Surface-mount components (SMDs) on the IC-705 are microscopic—0402 and 0201 sizes are common. The parts list provides:
