Ensoniq VFX motherboard repair

Ensoniq VFX motherboard repair

2008-08-19 by Simon Rodwell

Hello,
My VFX is in a pretty good state but I am experiencing the keyboard calibration error a little more than I would like.  I suspect this is the split motherboard faulty connector problem and was wondering whether it was worth attempting to fix it myself.  This would require taking the keybaord to bits I know and I haven't a clue how to do this nor what kind of wire to best use to replace the faulty connector between motherboard 1 and 2 which I think are at the base of the keybaord case.
Can anyone furnish me with step by step instructions on how to effect this repair.  Haven't found anything other than very general summaries of the fix on the internet so far. I don't think I will want to attempt it unless I have some pretty detailed instructions to go on as the keyboard is worth far more to me for nostalgia than for money.
Thanks

There is a web page somewhere that gives pictures and instructions for this (Im at work now and dont have access to my home computer, if I find it later Ill forward it to you). I had the same problem with my SD1, and it was a simple fix as I recall as far as access inside. Caigs De-Oxit is good for cleaning up connectors if you choose not to hard wire the boards together.

Look here:

And if you are anywhere MK, I'll have a go for you . . . just about 
to do it on my VFX which I thought was already "fixed" but has 
started having the problem, so I took it apart and hey it's the 
standard connector blocks . . . benefits of mostly using it as a 
sound module, not a "playing" keyboard I guess!!!!

I had an old 'original' VFX that had the keyboard problem. It was funny because the dealer
that I bought it from, used in 1991, sent it back to Ensoniq for repair. Ensoniq returned the
synth to the dealer and claimed it had no problem. I took it home and again, the keyboard
failed its calibration routine.
I then took a look for my self - my solution was to merely clean the contacts on the key-
board's two circuit boards. The problem went away and never returned (I sold it several
years later).
I thought I would mention this as not everyone is handy with a soldering iron. I would
definately NOT used the alternate fix mentioned on the website: 'to push down on the
center of the keyboard until you hear the circuit boards shift.' OUCH!
