I will post a picture of the connector set up for 230/240v. (if some one knows of a post covering this already please post a link) also you can do a voltage check and see what voltage you are getting to your G.I.s circuit with a multi meter. set the meter to A.C. and test across J115 pin 3 and pin 12 (this is just one of the several G.I. Circuits and it is located next to the G.I. fuses)
the manual says 6.8 volts so if it is higher than this the mains voltage jumpers are probably set to a voltage lower than 230v.

I would be happy to repair the G.I. section on your driver board if you need it done.
