[sdiy] Kawai SX-210 - it is NOT the battery....

[gilwein at walla.co.il]

More on my miserable Kawai SX210....

On the last 3 days I've been working on complete restoration of the battery section,
where the acid was leaking over... took all the parts in the area (two ICs, and a few transistors and resistors).
Than I copied the traces and layout to a paper (drawn it).

Than scratched the upper layer of the board so there was only the plastic left.

After that I just built the whole section using point-to-point wiring (the same way I build all my 11 guitar effects...)

Unfortunalety, as I powered up I found that the same problem/s persisted !

Again, the first problem is the dial wheel (increment) that doesn't respond,
and this occured during my last tried to repair the instrument, it has worked till than !

The other problem is that on specific presets the sound get scattered when very certain key combinations
are played, and also a few keys can playes a duller sound than what the preset is.

Any direction ?? I can post the schematics if it can help !!

Thanks in advance I *need* to repair is it's a rare wonderful sounding instrument !

Gil.
