Re: [Ensoniq-VFX-SD] Re: SD1 won't 'recognise' keyboard...

2008-06-16 by Jonas HÃ¥kansson

Hi!
Once a long time ago my VFX SD hung up in a strange way. It was so long ago that I don't remember properly but it was something like this: I turned it on and it locked and did not start up as normal. Some kind of start up process lockup. I did not know much about electronics back then so I did not dare to open it and start to look for errors. But after some days I got tired of the situation and in desperation I turned the VFX SD on and off several of times rapidly. And guess what! When I have done that 6-7 times the software lockup was gone!! In some way the keyboard rebooted and it worked like normal again. It has never been any problem since. So switching the powerbutton on-off several of times is some kind of signal to the software to reinitialize or what do you guys think???
Best regards Jonas Hakansson Sweden.

Thanks for all your suggestions so far, especially Steve.
Here's how I stand at the moment....

All keys replaced after checking all the circuitry beneath them.
(Soldered over the connecting ribbon joints to make sure and cleaned
the board surface of crud and dust)

Still the same message - calibration error. After pressing
re-calibrate about 6 or 7 times I get the keyboard not
found/recognised message.

** If I press 'ignore' (to get the patches displayed) and then do the
're-initialize' function - it all goes dark, permanently, with disc
drive light flashing once every 5 seconds or so, until I switch it off.

Powering back up starts the whole thing over...

Should I just give up..?

Thanks,
Tom
