Using the soldering iron, disconnect the four wires soldered to the main board. For more information on how to solder and desolder connections, please visit this guide. Be careful when using the hot soldering iron. Move the ribbon cable out of the way as well; it is easy to burn it or yourself when using the iron.

My D80 is displaying ERR no picture is saved when I click on the button, I can hear the shutter but no picture is saved. Firm ware is up to date. I was told maybe the ACU plastic screws are broken, where do you recommend buying parts? Your instructions are clear for removing the board. Thanks for that.
