Canon EOS Rebel T3 Main PCB Board Replacement
Introdução
Ir para o passo 1This guide shows you how to remove the main PCB board in the camera. This is useful in the event that the main PCB board is damaged and needs to be replaced, or if you need to access other parts such as the SD card board, or the imaging sensor.
When you install the new main PCB board and are reconnecting the cables, note the single round black cable that leads to the top cover. This cable connects to the right side of the board and the connector is attached to the back of the board. To reconnect it, you simply need to push the cable down into the hole on the connector.
This cable is a fiber optics cable used for the camera flash. Forgetting to reconnect this cable will likely cause the camera flash to no longer function.
The Phillips #000 screwdriver is marked as an optional tool as you can always use the JIS #000 screwdriver in its place (JIS screwdrivers won't damage Phillips head screws).
