Hi,
I bought this yesterday to mess with. There's no lights, no buzzing, nothing when it's plugged in. I'm a little too amateur to use a multimeter when it's plugged into the mains so I've not tried.
The PSU board looks burnt out. The metal shield above it was brown, as is the underside of the board. Some of it was dust, and some came off with electrical cleaner, but not all. A lot of the solder on the bottom looks discoloured too.
The top of the board is here, and the bottom is here. That large capacitor on the top (labelled 25/105/U40) has both solder joints discoloured (the other bad joints looked to be from the heatsink?) so I was wondering if I should try to replace it. The top of it wasn't domed, but the plastic above the top was (chipping the plastic off shows the metal top to be flat).
I've got a few questions:
I'm very new to this, so please be gentle.

I've got a few questions:
- Can anyone help me identify that capacitor?
- Do some of the tracks look broken? Should I try running a bit of solder along them?
- Is there a fuse on the board I should replace? Sorry for how amateur this is, but does anyone know where it is?
- Short of replacing the board, does anyone have any other suggestions to help me get started?
I'm very new to this, so please be gentle.
