Panasonic Lumix DMC-G7 Troubleshooting

The DMC-G7 is rated for 350-360 still shots per full charge. If you find the battery is performing notably worse than this…

Ensure the battery has fully charged. The original Panasonic charger will change the status LED to green when the battery has completed charging.

Consider the age of the battery. Lithium-ion batteries can only go through so many recharge – discharge cycles (approximately 500-1500 depending on various factors such as temperature, storage conditions etc.). If the battery is over 5 years old, it is possible the battery is reaching the end of its useful life and should be replaced.

When you plug in the SD card the camera does not detect it properly or does not respond at all…

Attempt to reformat the SD card using the camera’s formatting tool. To format the SD card, follow this guide.

Ensure SD card pins are clean (free of debris and gunk). Ensure slot is free of dust using compressed air (do NOT blow with mouth into the slot: moisture from breath could cause more damage.)

It is possible the SD card lock tab has been moved if the SD card has been removed and reinserted several times.

Camera randomly stops recording data to card or gives card write error…

The Panasonic Lumix G7 can only record continuous video for 30 minutes or 4GB. The video normally rolls over, automatically creating new files. If recording completely stops after 4GB or 30 minutes, reformat the memory card.

It is possible the current memory card is not fast enough. When recording 4K video, the camera can write at speeds up to 100MB/s. 4K video recording requires at least a UHS-3 memory card. Make sure the card used is at least UHS-3. Some SD cards advertise greater read/write speeds than they can actually maintain. Try using a different SD card.

Attempt to reformat the SD card using the camera’s formatting tool. To format the SD card, follow this guide.

Defective memory cards may operate at reduced transfer speeds or not accept written data at all. Try using a different SD card. If the second card works, reformat the broken card. If reformatting does not resolve the issue, replace the card.

The internal flash does not emit light when taking pictures.

The flash cannot operate until it pops up. Press the flash open button to the immediate left of the electronic viewfinder.

The flash is disabled in silent shutter mode. Go into settings and turn off silent shutter to re-enable flash operation.

The flash PCB contains two fuses. These fuses may occasionally blow. Access the PCB and use a multimeter to check for continuity on each fuse. Visit the flash fuse replacement guide to learn how to replace the fuses.

If the flash capacitor fails, it will no longer build up the energy to flash. Check the flash capacitor value using an ESR meter. Visit the flash capacitor replacement guide to learn how to check and replace the capacitor.

When flipping the power switch the camera does not boot…

The battery may be depleted. Plug your battery into a wall charger to charge up your battery.

The battery contacts could be dirty preventing the battery from making a complete connection with the camera. Clean the metal contacts using 90%+ isopropyl alcohol or blow out any dust using compressed air.

The camera may not fully reset until all components have discharged. In order to ensure that all components have discharged, a power cycle is required. To power cycle the camera: pull out the battery, flip the power switch to the on position for at least 10 seconds, flip it back to the off position and reinsert the battery before attempting to boot again.

The charger for the battery could be damaged. Ensure the status light is on when the battery is in the charger and the charger is plugged into the wall.

The camera does not connect to a wireless network, or other devices will not connect to the camera’s wireless network…

If the camera has trouble connecting to phones/tablets, ensure that the version of iOS or Android supports the corresponding application (iOS 6.0 and Android 4.0). In addition ensure that the application installed is the appropriate application for your device and is up to date.

If the camera has trouble connecting to a TV, ensure the TV supports the Digital Media Renderer function of DLNA and that the TV is in DLNA mode.

If the camera has trouble connecting to a printer, ensure the printer supports PictBridge and is compliant with DPS over IP.

If the camera has trouble connecting to an AV device, ensure that the device supports the DLNA standard and is in DLNA mode.

If the camera has trouble connecting to a Windows computer, ensure that the user account only contains alphanumeric characters and that the folder to which the files will be sent has sharing enabled. Check to see if the computer’s workgroup is set to the default of “WORKGROUP”. If the workgroup is not the default, then, in the PC connection section of the camera’s WiFi settings, change the workgroup setting to match the computer’s workgroup.
