简介

Use this guide to remove and replace the PCB flashboard from your Canon EOS Rebel T6i camera. The PCB flashboard should be replaced following damage or exposure to the capacitor and/or the circuit itself. This is a step-by-step guide and each step should be followed in chronological order to ensure desired results.

You will need an iFixit opening tool, a spudger, a JIS #000 screwdriver, needle-nosed tweezers, a grounding strap, and a digital multimeter to complete the removal process.

Take caution when unassembling your Canon EOS Rebel T6i device. There is potential for device damage during the unassembling process.

**CAUTION(Electric Shock): Be careful not to touch the terminals of the capacitor (black cylinder). This can cause the capacitor to discharge.

Using a metal spudger, pry the rubber grip off of the casing on the left side of the camera.
Potential for device damage: Be careful not to rip the rubber with the metal spudger.
Remove five silver 5.8 mm JIS #000 screws from underneath the grip.

步骤 5

Carefully use the plastic opening tool to pry the casing apart along the seam.
Follow the seam with the plastic tool until the back is ready to remove.
Potential for device damage: Make sure you use the grounding strip to remove the chance of discharging static electricity into the internal components.

Notice the two connections attaching the back of the camera to the motherboard.
To disconnect the white wire, pinch the wire casing and pull it directly out from the camera.
This may take a very small amount of strength; however, do not force or pry it.
To disconnect the ribbon connector, softly pull the back away from the motherboard. It should come undone with little force.
Once removed, set the back in a safe place.

翻译

步骤 7

Remove the five ribbon connectors along the bottom of the assembly using either needle nose tweezers or a plastic opening tool to flip the small flaps to the "up" position.
Use a nylon spudger to pull each ribbon connector out of its connection using the hole in the center of the ribbon.

步骤 8

Remove the button cell battery from the motherboard using a pair of tweezers.

翻译

步骤 9

Disconnect the small plastic connectors on the top left corner of the motherboard by gripping the small plastic portion of the wire and gently pulling out of the connector.
Disconnect the three ribbon connectors along the top.
Don't detach the connectors underneath or the ribbon connectors with the foam block, as these will be removed later.

步骤 10

Remove the four screws from the front of the camera. There are two screws above the lens mount and two screws inside the lens mount.
Remove the four screws from the bottom of the camera.

Using the plastic opening tool, pry the front of the casing off of the camera.
Warning: Electric Shock! Be careful not to touch the terminals of the capacitor (black cylinder). This can cause the capacitor to discharge.

翻译

步骤 12

Remove the yellow and red connections on the front near the black cylinder (capacitor).
The yellow connector will just pop out if pried from the bottom using a plastic opening tool.
The red connector will pull out of the casing with either a plastic opening tool or a thin set of tweezers.
Warning: Electric Shock! Be careful not to touch the terminals of the capacitor (black cylinder). This can cause the capacitor to discharge.

翻译

步骤 13

Remove the diopter adjustment knob next to the viewfinder using a JIS #000 screwdriver.

翻译

步骤 14

Remove the entire upper flash assembly by gently pulling it up and off the camera.
The flash assembly is sold as a single piece.

Caution: Failure to follow these steps may lead to damage or injury from electrical shock. Before removing or touching the PCB board, the capacitor needs to be checked for voltage. This device is the black cylinder on the camera.
Place a voltmeter in parallel with the capacitor. If a charge is detected, make sure the battery is removed from the device.
The positive pin is connected to the positive terminal and negative to the negative terminal. Switch the setting of the multimeter to ADC for direct current amperage.

翻译

步骤 20

The meter will fluctuate with a current until reaching zero. This process will discharge any residual charge.
Caution: Failure to discharge the capacitor may lead to electrical discharge and shock. The meter must reach zero to prevent any further damage to the camera.
