I picked up a switch off ebay that somebody else tried to repair. The unit didn’t power on.
I replaced the Pl3 usb chip as it was crooked from an attempted repair it looked like. I also added a line from a pad that was lifted to the filter. They also blew off some caps around the VCC on the opposite side of the chip. As they were decoupling caps and I didn’t have .1nf around in that form factor I just crossed my fingers.
It powered up and worked no problem, but then the USB-C would only charge one way. It looks like they also replaced the USB-C connector but they were consistent enough to mess that up as well. None of the exposed pins were actually soldered to anything, they all wiggled. Also when I plugged it in the dock it didn’t do anything, the screen stayed on and no green light, nothing on the tv.
I reworked those pins on the usb-c and now the unit charges either direction.
Now when I plug it into the doc the screen goes blank like it should but still no output to video.
I have a new USB-C coming and I ordered those caps.
Its all I can think of doing at the moment. If anyone has suggestions I would love to hear them.
