Doubt it's "a simple problem".
BY NO MEANS "try to repair " it by fitting a larger fuse, or worse, a nail/aluminum paper/etc.
Contact http://centauramp.com/index.html and ask for the schematic.
And if they won't send a copy, ask for an authorized service technician they recommend.
PS: and please do not double post, once is enough.
