sd1 battery died, changed, still get low voltage message

2009-01-16 by markbreton@ymail.com

bought the battery off ebay, reads 2.97 volts.  metered the mainboard, 
power is getting to where it should. the display lights are dim, the 
buttons change presets but what tiny little bit of sound that comes 
out is the same no matter what.   it sounds like a sawtooth, doesn't 
change pitch no matter which key i hit.  the sequencer will not stay 
loaded. i read the posts and saw somewhat similar problems. do you 
think it is the main power supply or a cap that regulates it?  has 
anyone dealt with www.thesoniq.com for repairs? anyone have a 
schematic source?
thanks so much, i am glad to be a part of this group!!
