Re: [kawai_sx210] Re: sx-210 still being investigated!

2005-09-29 by Mark Daborn

Hi,
Since my last post, the SX-210 has sat gathering dust in a vacant room at work awaiting the
skilled hands of my electronic engineer colleague.
I have, however, paid for and downloaded the SX-210 service manual.
His eyes lit up when he saw all the circuit diagrams and functional test procedures contained within...
He has told me that due to most of the components being "off-the-shelf", it's restoration is almost a certainty.
even if the main board is beyond repair, he pointed out that with the diagrams, he could re-design me a new one
that would do the job just as well.
However, we are assuming that the copy of the EPROM we took was sound and not corrupt!
If all goes to plan, i should finally gewt to hear just what a Kawai SX-210 sounds like in the near future!

I repaired my SX210 (battery leakage) by actually cutting off ALL the
traces, ICs and other components at the leakage affected area, and
rebuilding it by making point-to-point wiring and reinstallation of
the relevant component of course.

Usually when the battery leaks, it can do harm that is not visible to
the eye, so retracing is most of the times necessary and components
at the area are recommended to be replaced even if you can't see and
corrosion on them.

The problem you describe sounds like computer board malfunctioning
which is probably due to the leakage.
