Speakers don't work Yamaha YPP-15

Hello,

This can often be as simple as the speakers being unplugged, plugged into the wrong jacks, or powered off, so don't overlook the obvious and check to be sure. Also check the volume controls in Windows or your application to see that they are turned up and not muted. When you are sure the volume is turned up, the speakers have power and are plugged in, and the speaker configuration is correctly identified in Windows (some audio hardware uses a proprietary mixer control for this job), you need to verify whether the problem is with the speakers or the sound card. Connect different known-good speakers and see whether they work. If they don't, the issue is in the sound card-possibly the configuration of the card is incorrect or the card itself is defective. The first thing to try is clearing the ESCD in the BIOS Setup. This essentially forces the plug-and-play routines to reconfigure the system, which can resolve any conflicts. If this doesn't help, try removing and reinstalling the sound card drivers. Finally, if that doesn't help, physically remove and replace the card from the system. You might try replacing it first in the same slot and then in a different slot because timing issues can sometimes exist from one slot to the next. If that doesn't work, you must try replacing the card. If the sound "card" really isn't a card but is integrated into the motherboard, first try the ESCD reset and driver re installation. Then, if that doesn't work, you have to try disabling the integrated sound and perhaps installing a replacement card.

I hope one of these solutions help.

Hi.
I don't think both speakers are damaged unless, some kind of electric failure affected them, they just must be connect in the wrong way.

You can try one of two things. You can pull the fuse to the radio and leave it out for about 15 minutes to allow the radio to reset. Hopefully this is the case. If you don't know where your fuses are, you can also do what's called a dead battery reset. You disconnect the negative side of your vehicles battery and leave off for at least 15 minutes. This will reset all the computers too. If this doesn't work, just remember that the radio is 10 years old and if wasn't taken care of properly will malfunction at some point. Good Luck

Have you looked at the manual?

The NEW thing doesn't work.

Does the subwoofer work for setup? That would certify the hardware and speaker definitions are ok.

The PC has the responsibility for defining and sending out something between headphone and full-blown 7.1 though the HDMI. Check your PC sound controls and the "Information on HDMI" section of the manual.

For the radio mode, probably the only analog stereo source you have, read up on the STRAIGHT decoding mode and Sound Field programs.

Speakers don't connect to inputs. Have you looked at the manual?

Consider the speakers as major contributors to the 'sound'.

All sound is generated digitally and the pedal doesn't modify the sound, it just sustains the generator. This is a strange problem and best suggestion iis to find another unit and compare... it may be a characteristic of the design. There isn't anything that you can do to change this. It could be there is a bad ground inside the unit or the digital data is corrupt in the processor. The fact that it is on a particular set of notes is strange...I just checked on my Yamaha piano that is essentially the same electronics and I notice that on one octave above the middle when one strikes F# and G they "ring out". Now this MIGHT be due to the characteristics of the speakers. Those particular notes seem to clash more. I don't have other speakers on mine and unfortunately you did not mention what brand model you have attached. Consumer grade speakers like fancy stereo speakers do NOT do well on these instruments. One has touse pro grade speakers AND use proper interconnecting cables. The speakers, powered type, must be powered from the SAME receptacle as the piano to avoid ground loops.

Try headphones... possibly the switch contacts on the headphone jack which disconnect the speaker when headpones are plugged in. If you can hear via the headphones, check the switch contacts. Also look for a loose cable.

Contacts can oxidize when idle for a long time.

Sounds like the receiver needs a proper burial.

Try Fm radio with stereo mode to see if you can get 2 speakers to light up.

Hope this helps.

Computer sound. Check if speakers are working at another computer.. If so check that speakers mini jack are connected in right socket.(a dot with 3 brackets at 2 sides.) , should be a green socket fitted in a green female socket.. Still no sound install drivers and software that comes with motherboard, usually work 99%. There?s specific files needed for functionality depending on sound software that windows doesn?t have. If still no sound go to control panel, system,, hardware, device manager, sound video game controllers and uninstall all sound drivers. Reboot and let windows pickup up onboard sound and install drivers auto. if still no sound reinstall windows, make sure you?re not selecting new or format your hard drive, Ask someone that has done it before. This solves usually all my problems. If still no sound buy a separate souncard, they are cheap and use the disk that?s supplied.

check all speakers wires andcheck test mode. every thing ok, may be input wiring problem ,check every thing after that internalcircuit may be problem..
