Another little update, so fella from New Zealand got in touch over discord and he had taken his oled to no less then 3 repair shops after royally messing up a charge port replacement, 2 refused it and 1 charged a diagnosis fee and called it a no fix claiming it could not be fixed, here are the pics he sent me of the board:
So the board ended up in the air during the port replacement knocking off random components and crucially shields etc on the wifi area, bq area and also m92 area of the boards all effected, after two weeks in transit half way around the world I get it on my bench and its time to see what we can do
Under the scope we can see the wifi area is a mess:
And this is it once rebuilt
The components that were missing outlined, 13 around this IC, I also reballed the IC as it couldn't be trusted, most of the components were stolen from an OG switch using a spare oled board as a reference for values
Missing components around BQ
Missing components around m92
Fixed m92 area and I reflowed m92 just to make sure it was seated nicely
Same around BQ area, components replaced and reflowed, looking pretty good.
The guy sent me the new port he was trying to put on so I put that on the board and then was slightly disappointed it had a bent pin but that's just cosmetic the port is on there like a boss
Once tested I replaced the shield, shield cover, ground clip just above the port to the left, and then the two clips eaiter side of the board that hold the port shield in place taking the total components for this repair up to 22.
I wasn't 100% convinced we wouldn't find some other issues but on first test it fired into life, it took an hour and 30 mins total start to finish.
And this is why I love a switch, its not about the £50 I charged for the fix, its about the challenge and more than anything I love the responses I get from people...
