If you're in the UK (as your email addy seems to suggest) then which
part? I've got an SDS-7 that I've repaired a couple of times. If you
want I could maybe take a look at it. Note that I'm in the north-west
of Scotland, though, so if you're in (say) Brighton then you can
probably find a friendly neighbourhood electronics geek a lot closer.
The first thing I'd do (and this applies to ∗any∗ equipment this age!)
is to open it up and reseat all the connectors and chips, and remove the
battery. Then I'd carefully inspect the tracks on the board around the
battery, especially if it shows signs of leakage. I ∗really∗ wish I'd
taken photos of the repair I did to my Korg Polysix - the battery had
started to leak and the electrolyte had eaten some nearby tracks ∗and∗
the pins on a nearby chip. It was just possible to follow the route of
the old tracks with thin wire, but that's a fiddly job and not one to be
attempted unless you're very very sure of your abilities (and even then
I wasn't totally sure, but I couldn't exactly make it work any ∗less∗,
could I?).
Lithium batteries don't tend to leak, they just fail. The NiCads used
in some equipment do leak, and as I mentioned above, the juice will rot
the tracks on the board surprisingly quickly.
