Question about Musical Instruments

1 Answer

Headphones don't work right.

I have a Yamha PSR 500 keybord. When i try to use headphones with the mini plug and an adaptor the volume is very diminished. I have to turn the volume up all the way to barely hear it when using the piano voice. The headphones work fine when plugged into another device(mp3 player, my computer). I'm wondering if the adaptor is the problem? Without headphones the volume level is fine and everything else on this old keyboard seems to work!

It might be that the contacts for the headphone jack is very dirty. Try using a cotton swab with a wd-40 on it to clean the inside contacts on the jack.

My Yamaha psr-500 wont turn on. When I push the on button the speakers make a popping sound and when I hold the on button down I get static through the speakers along with 3 notes one after the other


Is this on mains or battery? This keyboard must be nearly 20 years old, it's done well! If you have batteries in but are using mains power, the power adaptor could have failed and not enough juice left in batteries to work. Try new batteries and try without any.

I have a Yamaha PSRE413. on/off does not work with adaptor, but works with batteries


If you are using the correct adaptor then the most likely reason is that the socket where the adaptor plugs in has broken away from the circuit board and will need to replaced/resoldered.




if you need a socket Google : Yamaha PSR power socket ( KPA3 / PA130UK / EPA3 ) (LB30226R)


OR if you have used the wrong mains adaptor and the polarity was reversed you may have damaged the diodes / voltage regulator on the power input.

Right channel cuts out when I increase the volume


Blown or defective Headphone Amp IC or alternatively a defective Pot. Either way only AVID can fix it for you.

Outside parts and service is impossible.

The keyboard is showing sign of power input but the screen is not lighting and produces no sound


1. Try the volume

2. Your adapter may not be the proper voltage/amperage. If the adapter has ratings listed, make sure they match the keyboards ratings.

3. Try it with the headphones. If they work and the speakers don't, you've narrowed down your problem. There may be some damage or wiring problem within where the board meets the speakers, and/or before processing.

4. Try it with batteries. If that works, you need a new adapter.

Marshall MG50 DFX amp line out/headphones not working


Contrary to what's posted above, the Marshall MG series does not pass the speaker power output through the headphone jack, and inserting the headphones into the jack does not disable the speaker. The headphone amp is a separate circuit and it's input is taken before the master volume. So Jan's post is exactly right. Turn off the master volume and turn up all the other gain/volumes as high as they will go. The other issue is that the headphone jack's output does not drive low efficiency headphones well, so you need some headphones similar to Sony's MDR-V700s to hear it well. Earbuds just don't cut it.

Yamaha PSR-27; NO SOUND


If it is very old, check if the volume control could be contaminated. Make sure a voice is selected via the buttons.

Do try the headphones before anything further.

No volume at all out of speakers PSR-E203. Plugged in to AC supply. Yamaha Portatone PSR-E203 YPT-200


Make sure you use correct power supply.

Try headphones. If they work, then the switch on the headphone jack that disconnects the speakers may not be working properly and not connecting the speakers.
