Single and Finger,is chords mode.
In Single,by press one key (eg:A) then chords A is heard,and so on.
In Finger,you must press 3 keys.Example: G-B-D,then you heard G chord. D-F#-A is D chord.
In Finger,lets say you press A chord and want to change to C chord by press one key C only,there's nothing change untill you press C-E-G.
Low, is for chords octave low.
Chords Off,no chords can be play,it mean overall full piano mode..
Single,Finger,Low, can be activate with Sync Start button.

Check with a small speaker or amp plugged in the back. If you can hear it then the jack in the back is probably not making contact. If no sound comes out there then the Audio Amp or it's circuity in the organ is more than likely to need repair.

I don't see your exact model, but there is likely a great deal of commonality with their product...

Might try that GX150 for example...

Sounds like a transformer problem or something else in the power section..maybe even a transistor....since the LED status light would be direct from DC power. Take it to a trusted audio electronic tech and get it looked at. Keep in mind that these amps are about $150-$200 used on Ebay so don't spend too much getting it fixed if it is indeed a transformer. I'd definatley get it looked at. I have a JC-77 and it rocks for clean!
