Hello, I have a Yamaha PSR 630 keyboard. It poweres up and everything seems to be working ...but no sound. Even when I plug in earphones. Im looking for a repair manual or schematic.
Any advice?
Thanks!

Hi -

I had sent a reply earlier but not sure if it got posted.

Try connecting the line outputs of your PSR630 to an external amplifier such as a stereo. If you have sound, problem is probably in the PA of the keyboard.

If not, try sending some MIDI data to it. If you get sound, problem could be with the keyboard mechanism.

I have owned several of the PSR keyboard and liked them very much, very reliable.
