Dead virus B, possible solution

[namnibor]

Hope you are able to sort it and be the winner in the end! If I for instance had something onviously beyond my knowhow that needed repaired on these fine instruments, I would gladly pay for an out of warranty repair, given that they would not reach an impass that would require perhaps a whole new board that Access simply no longer stocks.
I found out via a warranty I have from Korg on a still-new Radias Keyboard, that an authorized repair center on their official list is no farther than 2 miles from me and upon speaking to the repair shop on phone just to know what they work on, they told me they can work on most synths, save from items requiring mentioned brand new circuit boards when something is no longer under warranty. So, since I do not gig nor really move my synths from the rack/stand set-up in home studio and use power conditioners as a very pragmatic precaution--I do not expect to have any real big issues. Here in the USA, there's a shop up in Wisconsin called "The Synth Spa" (website of same name), that specialize in certain synths BUT I have a friend whom has used them to have any of the synths he has sold given a complete check-out and bill of health and they indeed will work on ANY brand; one just has to call or email them firstly and go from there--in case you needed to know. If the cost were to be prohibitive mailing a full virus keyboard to Access's repair division and out of warranty, would have to make a logical descision on that one. Kudos to you and people like TIMO on here that can do these open heart surgeries on their synths!!!
