Diagnosing battery versus body faults
A camera that will not power on needs systematic diagnosis before any parts are ordered. Tim checks the battery contacts in the grip for corrosion or bent pins, tests with a reference battery of known charge, and checks whether the body responds to a mains AC adapter if one is available. A camera that powers on from one battery but not another points to a battery fault. A camera that will not power on from any source points to a body-side fault, typically the DC-DC converter on the main board or a failed battery gate circuit.
Genuine batteries versus third-party packs
Modern cameras perform digital handshaking with the battery to read state-of-charge data and verify compatibility. Third-party batteries without the correct authentication chip are increasingly rejected by firmware updates, especially on Canon EOS, Nikon Z, and Sony Alpha bodies. A camera that throws an incompatible battery error with a battery that worked previously has often had a firmware update that tightened battery validation. Tim can test with genuine batteries and advise whether firmware downgrade is a viable option.
Charge port and USB-C faults
Mirrorless cameras that charge via USB-C are increasingly common, and the USB-C connector on a camera body sees heavy use. The socket can develop dry joints on the PCB pads, which causes intermittent or failed charging. Tim can diagnose and re-solder connector joints or replace the charge port assembly on supported bodies, which is usually a much cheaper repair than a full board replacement.
