Subject: [Simmons Drums] SDS9 start up problems


Hi all, my first post to this user group, I have an SDS9 module which
has been with me since new but only recently brought out of retirement
after about 10 years of being locked away in a cardboard box. The
problem I have is that at power on the unit flashes once (all leds and
displays) and then the display flashes a single number 6 and then seems
to shut down with nothing displaying and no leds luminated.
I have replace the onboard 3.6 V battery but still the same, any ideas?
Thanks for any help,
Regards,
Trevor

Thanks Jesper, as posted back to Berk Aarts:

Yeah I know sounds kinda wierd but had to start somewhere and
replacing the battery at least gave me static memory again, have
removed the voice eproms as suggested by Steve and still no result,
have the manual and there is no reference to the number 6 as an
error, have also checked the power supply (your advice) and all is
good there as
well, the only clue I have is that by removing the Eprom from inside
on the board (SDS9 6.0)nothing happens at all at power on and
reinserting takes the system back to the fault, could it be possible
that this eprom has lost information from the lack of power over the
period of time and is causing my errors? I assume this provides all
the other sound banks and if they are missing then I guess there is
nothing to display.
Thanks again
Trevor

Thanks Steve, the PSU produced the voltages you stated and I checked
with and without the main PCB connected so as to rule out a faulty
componenet pulling the supply down under load.
I do not have a schematic and have browsed the web for a service manual
or the similar but did not come up with anything which is why I
basically joined the user group for further help.
With the system EPROM is guess I was getting hopefull.
