Had a quick look round, can't find anything of use that might help, just the user manual. I'd be happy to look at it for you, see if there's anything can be done. I did find a firm offering a repair service @ £159 I think, but that'll be just a board swap if they have one. What makes you think its the transformer, assuming it is a transformer (without seeing it I hazard a guess its not, but is a choke). Can you take a pic of the board in hi res as near perpendicular as you can?
