简介
This guide will show step by step how to replace the PCB flashboard following damage or exposure to the capacitor and/or the circuit itself.
-
-
Remove all visible exterior screws:
-
Two 6.84 mm J000 screws on the right side
-
Six 5.33 mm J000 screws
-
Two 5.33 mm J000 screws on either side of the viewfinder

-
To disconnect the white wire, pinch the wire casing and pull directly out from the camera. It will take a very small amount of elbow grease. 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.
-
-
-
To remove the Ribbon connectors that have a locking mechanism, identify the flap on the ribbon connector. Use either needle nose tweezers, or a plastic wedge to flip the small flap to the "up" position.
-
Once the flap is up, use the plastic spudger to pull the ribbon connector out of the connection using the hole in the center of the ribbon.
-
Remove the button cell battery from the motherboard.
-
-
-
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.
-
Go ahead and disconnect all of the ribbon connectors along the top that you can get to. Don't worry about the connectors underneath or the ribbon connectors with the foam block, as these will be removed later.
-
-
-
Now that you have removed the flash assembly, it is time to remove the motherboard.
-
First, the three remaining ribbon connectors should be gently disconnected. They are both located on the upper right side of the motherboard.
-
The foam on second ribbon connector must be pulled back to remove it. Do this gently as to not damage the connector or the foam. There is a small switch under the foam that must be flipped up before the connector can be removed.

Warning - Failure to follow steps may lead in 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 battery is removed from the device.
-
Furthermore, The positive pin is connected to the positive terminal and negative to the negative terminal. Then switch the setting of the multi meter to ADC for direct current amperage. .

-
Caution - Using a magnetic tipped screw driver may cause damage to the board. ordinary bits are preferred. There are 3 screws that must be removed in order to disconnect the board.
-
Furthermore, there are several ribbon connectors that need to be removed. Marked in red.
-
Remove the four wire connectors on the front.
-
Remove the two wire connectors on the back.
