Normally 8 pin IC’s that run somewhat relative to the power supply is a switch that uses internal light emitting diodes and photo diodes. If all of that fails, you need to go a bit deeper and look at all the surface mounts next, including that little 8 pin IC at U3, especially.
They’re giving me an impression that someone tried to change them and they made cold solder joints. Nonetheless, it doesn’t even really look soldered in, along with C16. I don’t think the casing looks bulging on C14, it could just be the casing/shadow. Without Microsoft/RedOctane releasing schematics on how the board works, it’s safer to assume everything should be intact or it won’t power, so you should test everything.Ĭ14 and C16 look questionable to me, compared to C44.
That said, there could also be a break in a wire. There’s no harm in trying to see if it helps though. I never had an issue with continuity, personally, because the solder joints hold the wire through the board - the connections aren’t made on the surface with the adhesive. Which you have coming so you’re good there.
