the blue wire is usually AC for the feature lamp bridge and looks like it is going to the filter cap negative lead which is usually a black wire. I think someone has screwed around with that wiring so I would be double checking it.

Figure out the wiring first. Test the bridges. Add the safety fuses, see pinwiki or other guides. If the bridge is bad AC side fuse will sacrifice itself instead of burning the transformer.

The ground wires are normally black. Seeing a color that usually caries AC in the same area going the filter cap is concerning. It doesn't really matter what wire colors as long as the circuit wired up right. Hard to tell from your picture what exactly is going on but it looks like one of the wire insulation has melted off so that is a pretty good sign something is wired up very wrong or a bridge is shorted.

Hopefully no permanent damage has been done but don't power it up until you are sure it is wired up right, the bridges are not shorted, and the safety fuse added.
