> Two thoughts... first, that you can't perform a Factory reset and patch names are garbled implies your AN1x needs a new battery. See an authorized Yamaha service center in your vicinity - you can probably locate one from a Yamaha website. An OS update won't solve that issue.

There are some tips in the list archives and the Files section for disassembling an AN1x, not a hard feat by any stretch if you've the time and inclination.

Just to add to what Jon has said, it's also my experience (as an electronics engineer in an earlier life!) that and socketed integrated circuits as well as connectors can come loose over time due to a phenomenon called "thermal creep". If a circuit gets warm and thus heats up and cools down as you turn it on and off then the expansion and contraction due to the heating/cooling can slowly work chips out of their sockets over the course of months and years. I've even had extreme cases on boards that consumed a lot of power (and thus dissipate a lot of heat) where if I had turned a board upside down then the chips would have fallen out! This obviously doesn't apply to soldered components, but typically things like OS ROMs are socketed. So if you have strange behaviour you can't explain then it is always worth giving socket chips a firm press. I'm not saying it' the cause of your problem, but if you're clutching at straws......
Sometimes connections also oxidise over time as well depending on the material that they are made of, so taking out and reseating connectors is also worth doing.
If you don't get a reply from Yamaha, then please let me know. I have a few contacts in Yamaha UK who may possibly help shed some light on the mystery.
