Just received my Phantom 3 HDMI upgrade board. I thought I would do a quick post to show how simple this upgrade is as long as you take it slow.
First the board and cover
To get started remove the rear port cover plate, 4 1.5mm hex screws
Now the part that people should pay attention to. If you haven't worked with these type of ribbon connector before please take your time. On the opposite side of the ribbon is a little black tap. Use either a tip of razor blade or a VERY small flat head screw driver to flip these up, to the unlocked position. There are 3 tabs to unlock
Make sure all tabs are flipped completely up to the unlocked position
Disconnect the 3 ribbon cables and remove the 3 screw, the board will now be completely removed.
Install the new board but connect the large ribbon cable first, this will make thing much easier
Connect the last 2 ribbon cables and secure the board with the 3 star screws. Make sure you lock the ribbon connectors securely . They will lay completely flat.
Last step is to install the port cover plate. Line up the connectors and apply a light amount of pressure to see if it seats correctly. Don't not force it!!! Use the 4 1.5mm hex screws to secure the cover.
All done Please feel free to post any questions about the install. I would rather have people ask than damage something. But its a super easy install so you all should be fine
