Hi Frog, i just managed to repair mine.
I actually wonder what replacement board you ordered and where: on my initial search for this board i only found them offered on a Brazillian webshop and not on the known Chinese site(s), we're talking about Via Epia 20000 (the 10000, 15000 and successors are not difficult to find).
What you can do is see if the caps have a bulged top, if so, see if you can find a company or person with the right tools (!!!) to work on these multilayer boards, as replacing is not as easy as in 25 yrs+ electronics.
But then you may be good again for a handfull of pounds :)
BTW: i also heard of crazy prices (1000 euro) but that depends on which dealer: B&O charges 550,- or so for a board but if they ship the unit to another repair place that miraculously seems to double....
