How to change speaker yamaha keybord - Yamaha YPT400 61 Key Portable Keyboard with Touch Sensitive Keys

Check with a small speaker or amp plugged in the back. If you can hear it then the jack in the back is probably not making contact. If no sound comes out there then the Audio Amp or it's circuity in the organ is more than likely to need repair.

Don't mess with it and risk voiding your warranty. These are a servoed speaker and there is a problem with the feedback in it. Exercise your warranty immediately.

Have you tried headphones? - did it work or still silence?

what the #full Model number of this keyboard?

Hi,

You can download the complete instruction manual in PDF format by clicking this link.

• You'll require Adobe PDF Reader installed on your computer to view the manual. If it is not already installed on your computer, download it free from: http://get.adobe.com/reader/

Hope this solves your problem. Thanks for using FixYa.

If you then click on the "Resources" tab, you'll be able to download the manual. The A/C adapter you're looking for is the "Yamaha PA3B Power Adapter", which has now been discontinued. You can use an universal power adapter instead using these specifications:

Input: AC 120V, 60HZ
Output: DC 12V, 700mA
Polarity: Center Positive (+)

Hope this helps. If so, please rate. Thanks.

My keyboard yamaha psr2000,so I want parts silicone rubber keypad 61 and including electronic board,thank you.

the problem is the main output amp. It is an IC so it is better left to a tech to put it in. Just had the same problem with mine. Seems to happen when unit is left on overnight.

Depending on what you want to do...

If it's only music Mixing, you will have to plug your keyboard via audio jack to the line in of your computer. Then Audacity (free soft) can do the job.

If you want to edit midi file with your keybord you will need midi editor software like Linux-Rosegarden or if under windows try LMMS (all free soft of course).

Good luck
