I had issues with my Korg CX 3 organ at a gig a week and a half ago. When I powered it up, the LEDs just blinked at me, so I powered it off and blew it off as it being a power issue - that there wasn’t sufficient power at the outlet which the entire was using (that, or a battery type issue… i.e., I really had no clue what was wrong with it. So powered it off and played the gig without it (I play piano mostly, anyway).
When reloading to go home I had noticed something rattling & rolling around in the CX. I get it home, unload it, put it on the kb stand and power it up only to get it blinking at me again (insufficient power not an issue). I power it down, remove the top and discover what looks to be 3 small metallic cylinders encased in plastic whose broken edges (like broken glass) suggest they’ve broken off from the internal chassis somewhere, i.e. I have no clue what they are (some sort of spacers?) or where they go. Anyway, one of these cylinders was resting upon some of the internal guts/circuitry. After removing them, on a whim, I re-plugged the power cord, turned it on, and voila… no more blinking lights, and full function (albeit via headphones, haven’t tested the audio outs yet).
WTF!!? 
Until I find out what these spacer type thingies are and where they belong and their relative importance, I probably won’t use it live.
Seriously, what’s the best VSTi Hammond B3 I should look into?
