Fix USB port on Wacom Intuos 5 - PTH850
If your Wacom Intuos 5 tablet is not or intermittently recognized, this is likely due to a failing solder of the USB port on the tablet motherboard.
You can open it by removing the screws and then pop it open with a flat metal tool to release each hinges. You might break some but it should be fine...
You need to assess the damage first. Check on the type of crack and the type of the soldering problem you have before doing anything. You may be able to resolder the mini USB port.
If you can't you can cut off the head of the USB cord, keep the USB A part and stripped each of the four wires of
their casings so that you have some pure metal wire to work with.
The USB port on is Wacom Intuos 5 - PTH850 is mini USB B. This is the wiring:
You can then solder the wired directly to the TVS (transient voltage suppressor). Like this:
Then plug it to a computer check that you have 5V between Vcc and Ground. Then from the back of the TVS and the Ground. If not you can bypass the TVS.
Then you can us some epoxy to hold the cables together and dig a hole in the back cover so that it will allow the cable to pass when you reassemble the two parts together.
Here is a photo of the final work:
Hope it will save your 600$ tablet. Especially in this new era of expensive electronics..gwq
