I have a yamaha DGX-620 but the screen is blue with some lines Please tell me what to do !!!!

Could be bad connection of the LCD glass to it's socket.
You need a specialist to look at that, very delicate.
If not----
Change the screen, probably the whole board with driver chip. Check with Yamaha.

Yamaha DGX 220 keyboard all E and Bb keys above middle C will not play

Try unplugging it and also remove batteries if it has any. Then plug it back in and everything should be back to factory settings. I don't know what to to beyond that.

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 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.)
