Even if it's dark can you see the displayed images/text/numbers? If so, it's clear that your Lcd is not receiving one input from the Pcb, I think there's no damage yet. This should be only with the display cable and the connectors, maybe on the display terminal or on the pcb terminal. Open the unit and again refit the lcd connector (flex cable). That'll fix your problem. Recently one of my friend had the same problem after we cleared out some dust. Hope this helps. Good luck. Thanks for using FixYa.

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.

Screen is blanck can not see any of the database

If you haven't already, try to adjust the LCD Contrast by rotating the knob on the rear of the keyboard. If that doesn't help and if every thing else functions the Contrast pot is damaged or the LCD needs to be replaced. Those would be the most likely causes.

I have a Yamaha dgx 330. I was playing it at my gig when all of a sudden my sustain pedal stopped working. It was working fine right before that. I could only play fast songs after that. I also have a Dgx...

Two possibilities come to mind.

These footswitches DO go bad and require servicing (east to work on) either cable breaks someplace due to vibration and flexure or the contacts get dirty inside... simple to disassemble and clean.

The other thing is polarity. I know you said it isn't polarity, however should you be holding or not holding it down and the power glitches, the keyboard may read a NEW polarity. Often the power can be very "dirty" at venues. Also sometimes the power cord connector can become marginal causing momentary power loss... USUALLY you would notice this happening.

A bought an Yamaha DGX 640 grand a week before and the note sustain for a longer duration and overlaps with the current playing notes. I checked the sustain in the function setting and it is also showing ...

The function setting is for the PANEL sustain (Page 68 of your manual)

The other method of sustain is by footswitch or pedal option. See page 13.

If you use a footswitch, it needs to be a normally open contact type. If you plug a Roland type in, it is opposite polarity and will sustain UNLESS the pedal is pressed. Make sure nothing else is plugged in the sustain jack... headphones that are inadvertently plugged in there would sustain.
