    A great place to start is the Service Manual section of our forum. Motorola fails at quite a few things these days, but their service manuals are top-notch for the most part and the troubleshooting charts and theory-of-operation sections will greatly assist you in fixing these radios.

    Always suspect mechanical failures at first. Bad flex cables/grounds, corroded connectors, water damage or cracked/damaged PCBs or flex connectors. Mechanical parts are far more prone to failure than the electronics.

    Failing anything obvious with the mechanics, start by tracing the current as it comes into the radio. Check the internal fuses (very small surface-mount) and reverse-polarity protection diodes.
