Do you mean there is no sound coming from your monitors? Check whether you've accidentally diverted the main-mix signal from main-out (or whatever you have your monitors plugged into). Can you get a headphone mix?Also, dumb question, check that nothing is soloed!

Because it is solid state for one.

It is also a Class D type amplifier, so the 500 watts is only a a peak rating and not very accurate, it is not an RMS rating, there is a big difference.

Class D amps chop up the music stream so it is not a continuous signal like analog signals are. It has a generalized block diagram similar to a power inverter or an AM transmitter. You ear is not likely going to notice the difference.

Watch videos on YouTube about proper setup of a mixer/amplifier. Proper level setting at the different stages of the mixer is important to balance. You don't give us a clue as to what music you are talking about... if it is from a device plugged into the tape inputs for instance, the fault is your source is NOT providing adequate line-level to those jacks and you are trying to compensate with the master level. The master level should probably be around60% up in normal operation.

What is the make and model and i'll find you an owners manual for it

Chances are there is nothing wrong with the mixer. IF you accidentally turned on Phantom power, that would cause the problem. Phantom is ONLY used with condenser mics and a few DI boxes. Turning it on can create noise unless balanced lines are used everywhere.

My Yamaha P85 had a no sound problem too. I replaced the two 100uf capacitors at locations C216 and C217 on the board where the DC power plug connects. Fixed it right up.

Order the service manual from Yamaha.

Go to the menu and the settings, language & Keyboard Touch Input. Text Input under an other setting make sure that you have the sound feedback checked. If that is checked and its still not working try restarting your device. Sound feedback is checked; no sound for keyboard or menu/app selections.
When no sound is output even though the power is turned on, check the following points. Make sure that the master volume is not set too low. Set it to an appropriate level using the slider or knob. Make sure that nothing is connected to the headphone jack on the keyboard.

Hi Phil! If you find the schematic for Yamaha GA 15 ii, please let me know as I was looking for it as well. I was playing the guitar for a long time but due to all this college stuff, I had no opportunity to play the music at all and then my friend asked why not try these out and I have paid a professional writer to do my homework. Thanks to this writing service, I have time to play guitar but now I cannot find a schematic for Yamaha GA 15 II guitar amplifier.

Do the lights come on?
Have you tried the headphone output as well as the line output(s)?
Is the volume turned up?
Do you have it plugged in with the original Yamaha AC adaptor?

seems to be a standard acoustic setup to me. If it doesn't have all the string pins in it, you'll need to get some. you simply pull out the pin, put the string in, then wind it up on the machine heads (tuners) On this one you may need to put the strings through from the inside, I'm not sure about this particular model. I like a double wrap to start on the bass strings, but that's a choice I make. You could go with nylon strings, get ball end, they're easier to use than plain. It takes a bit of know how to do plain, thy have to be wrapped just right on the pins.

If you are talking about cleaning the rubber contacts I wouldn't bother. Once they start to fail then it is best to replace them. You can do this either for the octave giving problems or best to replace complete set. Main part is VY84670R your piano has 6 octaves of these. with a shorter part at either end.
