    • Using the plastic opening tool, remove screen protector from front of monitor.

    There's a layer of adhesive between the screen protector and the white plastic behind it.

    The cover is glued on. So you’ll nee d quite a bit of force to bend it up. But then it’ll come lose glue point by glue point. At first I was afraid that I’ll break it.

    • Disconnect speaker from monitor for ease of access by unplugging wire.

    Thank you so much for this - and thank you to the commenter who walked through the additional screen replacement steps! I’ve never done anything like this and I managed to replace the screen myself.

    Removing the large shell ground pins on the old receptacle was the hard part. I ended up cutting the part to pieces with some snipers then pulling each of the large pins out separately with small pliers and my soldering iron, I don't think I would do it this way again as its really hard on the pcb (I got lucky but its a little risky), heating the entire connector till all the solder melts and pulling with pliers is probably safer. Alternatively heating from the screen side may work but seemed like it would be hard to get the heat on enough pins at once to work.

    • Remove the old charging port and solder the new one in place.

    • After removing the old port make sure to clean ALL the excess solder from the though holes.

    • Add a little solder to each of the 5 surface mount pads on the PCB before putting the new port on. Its a bit of a tight fit between the screen and the port so getting an iron and solder positioned correctly without blobbing or bridging is hard.

    • Place the new port on and make sure the large pins fit though the holes (the won't go all the way though)

    • Solder one of the though holes to start (if you mess up the surface pads its easier to get back off if you only have to melt one structural connection)

    • Solder the 5 surface mount pads. If the port didn't sit all the way down to the PCB you can push each pin down with the iron onto the pad and into the solder. (pre adding solder to those pads helps with this)

    • Finishing soldering the though hole pins.

    • Flip the unit over to ensure a correct fitment.

    Where do you buy a new charging port? Also, you didn't include new charging port as an item that is needed for this tutorial. Might be self-explanatory but why say "no parts required" when clearly a part is required?

    In any event, thanks for this tutorial. Much appreciated!

    The part you are looking for is a female Micro USB B-Type solder socket. I no longer have the unit available to confirm, but I'll bet you could contact Infant Optics and confirm with them. Sorry I can't be of more help!

    10118194-0001LF made by Amphenol ICC works for this, it can be found on Digikey or Mouser.

I appreciate you posting this. What kind of new charging port did you use (USB type, size, etc) and does IFIXIT sell them?

Worth pointing out that this guide shows an older version of the DXR-8 (2014 printed on the PCB) where the microUSB port uses through-hole leads to connect to the board. Mine is a few years newer and the port was surface-mounted, which requires more skill and care to replace. I ended up ordering the part myself and taking it to a repair shop for them to do the soldering.
