The Yamaha AN1x Synthesizer mailing list

It looks more likely like a ribbon controller problem : play, hit it 
gently with your fingertip and listen...maybe you'll have to open your 
synth , clean and plug firmly the ribbon controller connector to fix it. 
The connectors and IC sockets are often the hidden "Achille's heel" of 
electronic devices.
For the supply unit : these wallwarts are often crap pieces of 
electronics, but mine works perfectly (at the moment, maybe 
tomorrow.??). The Yamaha unit is a bit expensive for what it is, but you 
can try any similar supply rated at 12V - 700 mA, "+" at the center of 
the connector. Don't try higher voltages, but a 1 amp supply will work 
even better.
Cheers.
