Tonight I performed a minor surgical procedure on my AN1x :)
For a long time, knob #4 has been loose, to the point where I had to stuff
paper bit into the knob just so it can depress. It got so bad that even the
slightest vibration made the value go schizo from 0 to 127...not good.
Also, in an unrelated malady, the ribbon controller had a tendency to be
hyper-sensitive.
So I flipped it upside-down, got out the powerscrew (which I highly
recommend unless you want carpal tunnel syndrome REAL badly), unscrewed the
whopping 33 screws on the underside, and popped the bottom metal lif off -
Yamaha did a very good job in making this as non user-serviceable as
possible :)
If you have any broken keys, be prepared to dismantle everything to replace
them. Actually I've seen worse (Ensoniq ASR-10, for one). To Yamaha's
defense, the thing had zero dust or dirt inside after 2 1/2 years of service.
Man, I wish I had a digital camera so I can show you folks...there's lots
of wire spaghetti, there's even these bendable rubber-insulated wires whose
sole purpose is to clamp down bunches of wires.
The mainboard (with the battery) is clearly seen towards the right. There's
two screws by the side where they fasten into the keyboard assembly. The
mainboard section lifts off, but there's lots and lots of wires that limit
its movement. I had to unfasten the aftertouch "AFT" cable and unscrew the
mini-board where the keyboard wires attach to (4 screws).
Now I can get at the knob assembly. There's two "card strips" (like small
versions of PCI cards in your computer of which 4 knob pots are attached to
per card. One was tight, the other loose. I was contemplating gluing one
down when I decided to go further and unscrew the metal plate that's below
the knob pots.
I was able to free the knob section, and - hello, what's this? A small hex
nut has come loose below the knob 4 pot! So I screwed it on back tightly,
as well as the other 7. That's what's been plaguing me all these years!
As for the ribbon controller, the ribbon ∗cable∗ connector seemed to be
loose, so I pushed it down.
Then I put all the wires and screws back where they belong, and I had a
good-as-new synth...
