Yamaha Music - Recent Questions, Troubleshooting & Support


There is power from the power supply if the logo is on the screen, although it could be it isnt providing full current. Whilst the logo is displayed the machine carries out a number of checks to ensure it is working correctly. Once these checks are completed it moves to showing the voices etc. If it hangs it has found a fault and further investigation will be required.

Hi,
Since your keyboard works fine with the PC. That means the problem is with the keyboard's Speaker. Either your speaker cable or speaker itself is not working... you have to identify that whether the problem is of speaker wire or speaker.... see that whether the service manual of your gadget is available or not.. if available then purchase the same. It will help you a lot for while repairing
Hope this has helped you....
Thanks...

I have a P-95 that stopped working as well. After contacting Yamaha, they told me that the P-95 is discontinued and not supported. I decided to diagnose it myself. First, I am an electrical engineer so, I was able to dig into the problem much deeper than the average Joe. So, the P-95 is powered by a 12v DC adapter. My adapter was producing 14.5v DC which is actually fine. I found a YouTube Vid to show me how to crack the keyboard open. It is well worth you time to find this vid as there are 57 screws you have to remove. Also, the small panel on the back MUST be opened first and the 2 ribbon cables must be disconnected before your separate the halves. I was able to find a service manual on line. The P-95 and the P-85 have the same guts. You must actually download the P-85 service manual as it has block diagrams and schematics. The power section is located on the AM board and is really a simple circuit. 12 volts run thru a fixed fuse, filtered and then is "switched" by a power transistor circuit ( TR-401, TR402). How this works is as follows, when the power button is depressed, the circuit is triggered to pass 12 volts through to two (2) 5 volt regulators. One regulator is draws alot of current and is mounted on a heat sink (IC401). This powers the computer portion of the keyboard electronics. Once the main computer chip sees power, it wakes up and then sends a second trigger signal to the 12 volt power circuit telling it to "stay on" until the power button is hit again. In my case, I was able to simulate the power switch signal and saw that the 12 volt switched circuit was actually working. So, then I focused on the 5 volt regulators. I suspected that the high power regulator was possibly bad. Sure enough, the low power regulator worked fine but there was nothing coming out of the 5 volt high power regulator lead. I ordered a new power regulator (Part Number NJM7805) and received it about a week later. I removed the old part from the board and replaced it with the new power chip. I was able to test the board by applying power and then simulating the power button switch and the power supply circuit began working like a champ. Power electronics can overheat and will eventually pop. It happens. I was fortunate to find the schematic and figure out what component had failed. Here is the link to the manual I used: https://www.manualslib.com/manual/957003/Yamaha-P-85.html?page=24#manual Also, this is the AM board. The bad IC was the single transistor mounted on the left hand side of the heat sink in the picture. It was not difficult to de-solder and replace. 5330-lg-undefined-undefined-0.jpg It's a shame that Yamaha is not supporting this keyboard any longer. It would be easy enough to keep a supply of AM boards on hand for replacement. Hope this helps others keep their keyboards up and running.

I have same issue anyone have any ideas?

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.

Providing it is plugged into the correct socket on the brain it is probably a broken cable. You could try using one of the other as a tempoary measure to check this if not then either the switching in the pedal has failed or a problem with the brain unit. Try cable & factory reset

What type of headphone connector do you have? The Yamaha keyboard headphone jack is a 3.5 mm stereo jack (like on a computer headphone jack). So if the headphones have a 1/4" plug, you need a 1/4" to 3.5 mm adapter.

I hope this helps.

Tom is probably right, the carbon contact on the switch wears out. Open the case and replace the switch. Part #40 Price £ 3.95 + postage if required 19153094-25qnjy3ifepwofogsdsgnkd0-3-0.jpg

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.

I once had this problem. Turns on but no sound. I tested the fan next to the power supply and it ran rough like it was worn out. I found the fan on eBay A5010L12S and replaced the fan. The Stagepas 300 came back to life. This fan blows toward the power supply and the other fan sucks air to create a circulation of air inside the mixer.

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? https://usa.yamaha.com/support/manuals/index.html?l=en&c=keyboards&k=DGX505 Owners manual in the link.
