[sdiy] Boss DR110 system noise

[Dave Magnuson]

It's quite possible that one of the VCAs for the hats, cymbal or snare is 
stuck "open".    The build quality of DR-110s is rather low... I see cold 
solder joints and cracked traces all the time.   So I'd look at the 
OH/CH/CY/SN sections for a bad solder joint first.   Do you have a scope?

Reply off-list if you need a schematic, and I can email it to you.

I have a Dr-110 that was working fine up until recently, one day I turned it 
on and the noise component (snare/clap) is continuosly sounding, other than 
this the machine works fine, but this problem makes it unusable. What 
component is it likely to be? Dodgy ribbon cable? Dead diode? Transistor 
gone kaput? Has anyone else experienced this or know what the solution could 
be? TIA
