OK, US=110-120 volts so that doesn't seem to be the problem. The reason for
me to ask is that Simmons was UK-based and the UK runs on 240, rest of
Europe 220-230, Japan 110 etc.
If the LED lights up (though dull) some electricity passes through, but
basically not enough. To the right, behind the mixer "card", the PSU is
located. If you are slightly experienced to looking on the inside of
electronic machines a lot of testing can be done with basic equipment. I
bought a electric current prober/tester at less than 10 USD. That fixed my
SDS-V.
1. Check the wall outlet - should be 110-120 volts in the US.
2. Check the SDS after the power switch - should still be 110-120 in on
mode and 0 in off mode. (mine was 0 in both)
3. Check the output of the PSU - should be 15 volts.
My guess is that your PSU is broken and gives a lot less. A new PSU should
cost something like 20-30 USD (fair guess).
If you're unexperienced with electronics or doesn't dare to try - check if
you can find someone who knows the basics... I'll gladly help across the net
if I can. Take it apart and finding the right places to check the power is
not hard - finding the guts to do it is harder! ;)
Good luck!
electronically yours, jesper
