The Yamaha AN1x Synthesizer mailing list

so friday my yamaha an1x worked fine at my buddies house for band
practice. i bring it home today, power it up and can't get any sound
out of the main outs, and the thing keeps rebooting every six seconds,
faster if i try to play any keys. I plug in a set of headphones to the
hp jack, and get about a half second of sound, between when the an1x
finishes booting up and when it crashes. That half second of sound is
pretty much normal, but as it crashes i get some nasty digital bleeps.
The more I play around, the longer the time between rebooting gets,
and as of right now i get randomly between 15 secs and a minute or two
. I still get no sound out of the main outs, and there is a loud hum
in the headphone jacks.... the hum is as loud as the signal, which
makes it almost useless... everything still works the same, as in the
knobs still do there assigned function, patch switching works, menus
work fine....

i've only had it for three weeks, and at worst have lightly bumped it
once in a while when transporting it to and from band practice. i have
noooo idea whats goign on here so any help would be greatly appreciated

Few things to try...1st, open the case and inspect the ribbon cable 
connections to the mainboard, something may have come loose. 2nd, 
try a seperate power supply - the AC adapter may have died.  3rd, 
perform a Factory Reset and see if that clears the problem.
