Lexicon mx 200 preset knob frozen
If unt was dropped, look for broken PC board in the vicinity of the rotary encoder. Also look at solder connections to make sure they are sound. A little contact cleaner applied to encoder through an opening so the spray gets inside will help clean contacts. If the knob itself is hard to turn, the shaft is likely bent, and there may be damage to the encoder itself.

We bought this upright piano for our daughter to learn on but I can't seem to find any info on it. Serial number 23930. Any info would be fabulous. Thank you.
Remove the front of the piano. Remove the middle C key complete from it mounting pin. You may find the production date and its full service history written in pencil on the side of that key. A piano tuner told me this after I told him that I had removed all the keys to clean them and I was surprised to see the whole history. It said it was standard practice.

I need to know the value of the Resistor "R1" in
Let us use a bit of logic to resolve this... I have an Axiom but it would be a lot of screws to take out to get to the part... so let us think about this. The resistor value starts with a "1" and we know it is 5% tolerance (gold). we know the resistor burnt up with likely 5 volts on it... Value could be 1000 ohms, however the voltages present (12 volts max) would NOT have burned up a resistor of 1000 ohms. The USB area is mostly 5 volts and across 100 ohms is only a quarter watt... not enough to really burn up a resistor... First thing is to MEASURE that the resistor s open... in spite of being burned, it MAY still be OK... these resistors now usually either open or remain close to their value. The resistor ALSO may be a fusible resistor intended to act as a fuse... Is the resistor open or not? is it near a resistance with a "1" as the first digit? If it is not open I suspect it is not all of the problem. In that case, look for a burned circuit trace on the board. If it is open, then MEASURE the voltage across the resistor with the power applied. If you find 5 volts, then it MIGHT be a 10 ohm used to limit the USB current to 500ma. Get back to me with your findings... I have unraveled many of these things...

Yamaha P-250 Stage Piano won't boot up...
Yamaha pianos go through a self test on start up. This could indicate a problem on the main motherboard.
Try a hard reset.
Hold down top C key while turning on.
Wait for it to start up, if it still freezes its time to take it to the repair shop.
