Sharp Microwave oven (Walkley S10)

I have a Sharp microwave oven that has been used for a year. A faulty diode probably inside. It has suddenly started sparking inside when used. Gives burning smell. Someone may be able to fix it to make it work. It can be fixed by trained professionals or who knows what they are doing as microwave reparing needs caution and can be dangerous. Pick up only.
Needs to go by weekend,13th Jan.
