LG Home theatre dvd repaired

The lg home theatre got damaged from excessive voltage.what I cherished about this dvd is that it uses a varistor as surge protector at the power supply and instead of creating serious damage to the power supply this varistor protect the circuit by shorting itself and break the fuse.I am always confident when this type of fault is brought to my workshop for repair.In the case of the one above I just change the burnt varistor and the fuse and it starts functioning again.
