My pointless and worthless repair is a 5V 3A switched mode power supply adaptor.
What happened to it was a leaky main cap, and when I plugged, unplugged then quickly plugged back the adaptor, somehow that made the PWM chip blew itself up.
The chip is OB2358AP. It cost about the same as a brand new adaptor, which is around $1.
I replaced the chip and the main leaky cap.
It's been running fine since then.
I also have another pointless and worthless repair.
A GTX 560 SE with missing components and ripped pads. Being an old DX11 card with only 1GB GDDR5, it has zero value, but I repaired it anyway.
It's also running fine in one of my computers but I don't like the blower fan design, because it fails to cool down the VCORE mosfets. One of these days I will probably 3D print a shroud for it, that will allow me to mount a standard 90mm graphics card fan which I salvaged from a dead RTX.
