No sound - Yamaha PSR-GX76


My son is interested in learning to play the keyboard and we just borrowed a PSR-GX76 from a family member. We plug in the power cord and turn it on. There is a orange box in middle that lights up with a picture of a keyboard on it. We get no sound out of it except when you initially turn it can hear a slight speaker noise. No matter what button you push nothing changes on the screen in the middle. No sound. When you push Demo...nothing happens. Any input would be much appreciated. My brother-in-law said he thinks this happened to him before but does not remember what key he pushed.

Thanks from an anxious-to-learn player in Oregon

Sounds like you may have connected the *wrong*
AC adapter.

The GX-76 takes a PA-3B adapter, I believe. If
you use any other adapter, you'd better know what you're doing because you can FRY the
components in your Gx-76.

Here is something you can read that should
help you choose the right adapter:
