Introdução

This is a full disassembly guide for the Panasonic Lumix DMC-GH3. Make sure you have the required tools, a bit of patience, and a lot of table space.

To start the disassembly, place the camera with the lens side down and the back facing you. This camera is assembled in planar layers, so it is best to start from the back. Begin by removing the eyepiece rubber. Slide this part up and it will reveal 5 screws. Remove all of them. Be careful to keep track of the order of these screws and the thread type. Use tape to keep track of the screws.

  • You will need a JIS0 and JIS00 screwdriver and a plastic spudger for this disassembly.

It's important to recognize that this is a camera produced by a Japanese camera manufacturer. The Japanese camera industry loves using JIS (Japanese Industrial Standard) screws over traditional Phillips screws.

  • Although PH#00 will interchange with JIS#00, it is not a perfect fit. Using Phillips can cause more wear on the head of the JIS screws and cause the screws to prematurely strip. If you are in a pinch, just go ahead and use Phillips.

  • Have both JIS#00 and JIS#000 screw drivers available for this teardown. Luckily, both bits are included in the ifixit 64bit kit.

  • From here on in, it is strongly recommended to use tape to keep track of the screws as you disassemble the camera. Screws are not always uniform in length or thread type, and some are aluminum, so tape works best here.

The rear shell of the camera should now be free to slide off the rest of the camera body. Rock the rear shell of the camera from left side to the right side to aid in the removal of the rear LCD shell assembly.

Once the electronics are exposed, it is highly recommended that you remain ESD safe. ESD can fry your precious electronics, and pass thousands of volts through components only rated for a few V DC. ESD can sure ruin your day if you are not careful.

  • Use an ESD mat and wrist strap, and make sure you are grounded for the remaining of the teardown. Make sure your ESD mat is connected to the ground of a nearby outlet, and make sure your house actually has a ground. Consult an electrician if you are unsure.

  • The removal of the top assembly requires you to remove the screws under the pop-up flash unit.

Instead of the following trick with the tape, you can activate the pop-up mechanism by pushing a black plastic lever upwards. The lever is located on the bottom left corner of the viewfinder. It is a bit deep but you can see it.

Since the camera is powered off and the battery is removed, the electronically controlled pop-up flash is non-operational. Thus, continuing the repair a bit of a hassle as getting to the two screws is impossible. This means you would have to pop-up the flash before starting the entire diassembly process! This is rather silly, because the pop-up flash gets in the way when disassembling the rest of the camera and it is a delicate assembly. I discovered an easy solution. Take a piece of blue tape, fold it over and shove it between the flash assembly and the shell of the camera.

Take this doubled over piece of tape and forcefully shove it toward the back of the flash camera unit. This will trigger the pop-up flash latch release inside the camera and allow you to continue the disassembly without ever needing power! Those two little screws are the culprit! The funny thing is the previous camera, the Lumix GH2, also featured screws here, but the pop-up flash had a manual switch! I guess the designers forgot about this when they implemented an electronic flash trigger switch. Those two little screws are the culprit!

You will need a long shaft JIS screwdriver here too! I didn't have one long enough, so I cheated and used a Phillips to remove these two screws Remove the two screws from the front face of the camera as well. Remove the one screw holding in the aluminum heatsink to the remainder of the camera.

The heatsink is held in on the right hand side by two small clips. Use the spudger fo un-clip the heatsink from the camera. With the heatsink removed, the sensor block assembly is uncovered and the battery compartment is finally unobstructed. Remove the circled screw from the battery compartment. This screw secures the front grip of the camera to the camera shell.

The grip should now be free and come off the camera easily. Panasonic hid the wifi unit under the grip. This is quite clever since the grip is entirely plastic and electromagnetic waves have little trouble passing through plastic. If they buried the antenna unit further inside the camera, the performance would be greatly hindered by the other metal shelled components. The top unit should now be loose and come free from the camera.

To remove the top, you should also remove the black screw under the grip on the front of the camera, which is above the wifi unit. You can see it in the 2nd picture.

The top unit should be held on only by the flash unit cable. Disconnect this cable and the top unit is now free. If your workbench is a mess at this point you're heading in the right direction! If your workbench is a mess at this point you're heading in the right direction!

The sensor block assembly, front shell and battery compartment are all that's left of this camera. Let's start with the battery compartment. Remove the two circled screws. The battery compartment should just slide up and out of the camera shell.

Before removing the sensor block assembly, the sub frame assembly must be removed. Remove the two screws circled. This will provide full access to the sensor block assembly mount screws. Remove the two screws circled. This will provide full access to the sensor block assembly mount screws.

This is the most important step in the entire repair disassembly process. This is the sensor block unit. Do not touch any part of this assembly other than the screw mount flanges on the magnesium machined assembly. In this case, I bent up the sensor ribbon cable lightly. I didn't touch any surface or place additional force on any sensor block part. Placing pressure on any part of this unit will change the sensor characteristic and and will require re-calibration and reprogramming of the sensor EEPROM. The tools for reprogramming the sensor calibration EEPROM are not publicly available to my knowledge. It is important to only unscrew the purple-tinted screws which are circled. Do not adjust or touch the spring loaded screws on the sensor block. These screws are adjusted at time of sensor calibration in the Panasonic assembly and testing factory.

  • The plane of the sensor is calibrated to the plane of the lens elements or lens mount. Adjusting the tension on any sensor box mount screw makes the sensor and elements out of orthogonal alignment.

  • That's it! Remember to keep track of those screws!
