The wire from pin 1 or 7 of CN1 on the GHL88L (left end) circuit board is open where it goes to the middle circuit board. This could be a bad cable, improperly seated cable connector, or a crack in the circuit board(s) connecting to these wires. These are the common matrix wires associated with only the C# and G keys for the left 1/3 of the keys. If more than 1/3 is dead, then the problem is likely on the middle board GHL88M that connects to the mating cable to the CN1 connector.

There are two wires dedicated to the keys for the two contacts that are used to measure velocity of the key strokes. There is a mechanical position between closing the contacts and the time is measured by the processor as velocity.

If you are the least bit worried about working on electronics you best have a service person do the repair. The keyboard has to be lifted out after removing the top and disconnecting other cables.

Yamaha DGX 220 All E and Bb keys above middle C will not play. All others OK


Just a shot in the dark but a lot of keyboards allow for splitting the keyboard in half or even in quarters to assign multiple sounds... have you tried a total reset? Or explore the manual for setting up a split keyboard. Might help.

I have ve a DGX 640. When the play the C, followed by D, the D is silent. It occurs also when I play the black key after its white neighbour.


Possibly a rubber contact switch problem.

Open up your keyboard if you feel confident about doing so.

Remove the rubber contact strip under the faulty notes and clear away any dust ( this can be a cause of the note not sounding ) Swap this rubber ( part 220 ) on attached picture with the one next door to it. If the problem has moved to the next octave then it is a worn rubber contact switch replace ( see link )

If not you will probably need to take to a repair centre as it may be more serious.

Where can i find windows 7 x 64 drivers please help mee !!!


Your Yamaha DGX 203 Portable Keyboard - USB-MIDI Driver Version 1.2.2 ie. for OS Win9x/ME.

Yahama site does not have the Win7(x64) Drivers ie. USB-MIDI for your Keyboard Model DGX-203

But you can try the USB-MIDI Driver Version 3.1.0 for Windows(R) 7/Vista/XP 64bit for Model DGX-520 @ http://usa.yamaha.com/products/musical-instruments/keyboards/digitalkeyboards/dgx_series/dgx-520/?mode=model

I can't assured you that it will works on your system. Since your Keyboard is no longer in production, I doubt Yahama will provide you with the official USB-MIDI drivers for your Keyboard even you requested for it.

I guess this is an option you can try and hope it works & good luck.

Regards.

I am not getting any sound from my Yamaha DGX 200,


From Yamaha DGX 200 Manual
  • Q-There is no sound even when the keyboard is played or when a song is being played back.
  • A-Check that nothing is connected to the PHONES/OUTPUT jack on the rear panel. When a set of headphones is plugged into this jack, no sound is output. Check the Local Control on/off. (See page 69.)
