<DIV>The smoke test has taken out some parts.</DIV>
<DIV> </DIV>
<DIV>Possibilities ........ bad driver board, bad solenoid taking
out driver board, I don’t think it’s the power supply because it’s fairly well
protected with fuses. </DIV>
<DIV> </DIV>
<DIV>OK so is your power supply the boat anchor attached to the inside
rim? the totally black with a ribbed heat sink?? the totally black
fairly light weight slim box full of holes?? or is it the wall wort and
black brick style consisting of numerous outboard components??</DIV>
<DIV> </DIV>
<DIV>There could be a pinched wire between the rail cover and the underside of
the piano. There are few thousand other possibilities for pinched
wires. Eliminate all of them.</DIV>
<DIV> </DIV>
<DIV>A shorted key solenoid is extremely rare but it happens. Make sure
all those pesky white connectors for each key solenoid are plugged in their
proper spot on the driver boards. It’s really easy to miss a pin or get
the order wrong under there.</DIV>
<DIV> </DIV>
<DIV>Wires pinched against the driver boards or routed such that eventually the
sharp points on the circuit boards will find their way through wire insulation
is a really good way to enjoy a PianoDisc BBQ. Dress the grey cable that
goes to all the driver boards and the CPU board so that it doesn’t get pinched
between the back side of the circuit boards and anything else. This cable
carries 45 volts DC with plenty of current. It’s enough, under proper
conditions, to fill the room with a PCB bouquet. The rest of the system
runs on relatively low current voltages used to move data and perform switching
operations. I don’t remember specific voltages right now. </DIV>
<DIV> </DIV>
<DIV>Your balance between the piano and the audio needs to be balanced.
This is a function of set up. Follow the instructions for iQ level set
...... from memory (mine), using the multifunction lever on the iQ
box, push it left until it lights up the level lights (two right I think) then
press in once, start a piece playing setting the volumes on the speaker and the
piano at about half, then press the multifunction lever again. All the
lights should light up for a few flashes and go back to only the power light
being lit up. ( I know I’m really close on these instructions) The
piano may play really loud for a few seconds and then return to normal.
Lowering the overall volume for the entire system should now produce much better
control and much softer playback.</DIV>
<DIV> </DIV>
<DIV>As with working on any sensitive electronic equipment, be careful not to
short things out or pinch wires. Be especially careful when reinstalling
the rail cover and dress the wires out of the way before you press it to it’s
final position. I know it’s a pain under there but I’ve learned to use my
knee on one end while working with the other end. </DIV>
