the fix is easy if you, or anyone you know, can solder, you just have to replace 5 or so capacitors on the power board, you can even buy the complete kit on ebay (although buying them yourself from RS, Maplin, or Conrad here is a lot cheaper)
Or if your not brave enough just replace the power board, again, its so common that ebay is full of repaired boards
Realistically its an hours work tops, the parts should be about 10chf, but this being switzerland I wouldn't like to hazzard a guess!!
