So after some investigation I have a burnt trace on the i/o board coming out of transistor Q5.

Is this repairable? Or must I replace the board? Either way, what could have caused this?

Recap: right VUK coil burnt, along with the wires coming out of it, and obviously the trace.

Any advice is appreciated.

Quoted from DCFAN:

Could be the transistor is blown, or the traces on the board could be melted/damaged.

Never tested a transistor before. I'll research that.

And tips on checking the board? If so, would it have to be replaced?

Update: so I removed all the connectors and pulled the i/o driver board and indeed there is a burnt trace coming out of transistor Q5.

Can a trace be repaired or do I need to replace the whole board? If so, any pointers on what could have caused this so that I can prevent a recurrence?

Thanks for the input guys. Will attempt to jump the trace.
