Yamaha PSR-GX76 musical keyboard problems

I just got my musical keyboard back from storage, and now when i slam down a grouping of keys, the thing craps out on me. Like there is a short, and too much feedback through the speakers, im aware that you shouldnt be playing that way, and thats not how to handle a keyboard, but im concerned about this anyway. Any ideas?

Does it have onboard speakers?

If so, try to tighten down (fix firmly in place) the wire mesh that protects the speakers, if it's loose, it will vibrate and cause distortion in the sound.

I once had to repair a portasound which sounded really crappy when a group of keys was struck at high volume, and it would only calm down when i fixed the speaker mesh so that it didn't vibrate with loud sounds.

You may want to put some rubber or similar into the groove where the mesh edge fits in to prevent it from vibrating (i solved mine just by tightening up the mesh strips where they protrude into the housing).

If this doesn't help, then it's something else (possibly a bad or dirty connector contact or a bad solder contact).

Yamaha psr-e333. Can switch on but cannot play even the grandpiano func. Its just "yamaha" written on the display..


To start with try a master reset, whilst the instrument is off press and hold the top (highest) sounding key whilst turning on.
When the screen displays Yamaha release the top key.
If this doesn't solve the issue then it could be a number of things as the keyboard does a self check on startup and will hang if a fault is found. Check each rubber switch is not stuck down or even missing this can cause this issue. Please report back either way.

Yamaha psr-gx76 keyboard-sound comes through headphones. Does not come through speakers.


Try cleaning the headphone jack. If that doesn't help, it'll be the amplifier board and will need to go to the shop.

Yamaha PSR 510 -- one of the white keys broke out. Need HELP!


I figured it out. Once the whole 61-key section is unscrewed (I believe its just one screw at the end and it simply lifts off) you have to take a flat head screwdriver and stick it in the top edge of the key rows and twist to force the little tabs out of the slots. Be careful because this is not easy and some of the little tabs might break off - it may not be crucial for the keys to snap back in, though. The first few black keys and the tab above are all one solid piece of plastic. All of the keys are grouped in groups of 3-5 or so as one piece. White keys are layered under the black keys so you must release black key groups to access the white key groups. Once you have forced a key group lose from its snap attachment you must also free the keys from underneath to fully lift the keys off the unit. You have to BREAK the hook shapes found on the underside of the keys (they rest up against the orange rubber lining.) Take wire cutters and snap off all the tips in the key group you wish to remove. Depress a key and watch the movement underneath if you have trouble seeing what I'm talking about - you will see the hooks - think of it as the bottom of the key because that is what it is. The piece you break off should be very small - just enough to remove the hook shape enabling you to lift the keys right out. This will not cause the keyboard to be unusable. It will only make it possible to bend the key up once everything is reassembled. It is the only way I see to free the keys and gain access to the action underneath. As for that...

The action underneath is made up of a pair of rubber cups that when pushed make contact with metal sensors. These rubber cups can tear causing them to fail to pop back up to rest position. I am trying crazy glue to see if this will repair the tear. If not then I will try double-sided tape so that the plastic key will pull the rubber cup back up with it (I hope) when released. Good luck. It is a great keyboard. Very sad to see it discontinued.

This is regarding the Yamaha PSR-510.
