SOURCE: Yamaha DGX-620 blank screen or screen with vertical lines

I`ve had a similar problem with a Korg that I use at the club and on gigs, I don`t know whether Yamaha use a similar method or not but when I stripped mine down, I found that the glass LCD panel is connected to the PCB via a ribbon cable which gets sandwiched between the PCB and the LCD panel when screwed up, It`s not soldered or hard wired to the PCB, It was producing intermittent connections between the uPC and the display panel where parts of letters and symbols were missing. When I removed the panel, I found that it was oxidized so I used some switch cleaner which doesn`t leave a residue (Don`t use lubricant or WD40 as this will destroy the LCD panel by penetrating between the layers of Liquid Crystal rendering it useless) and gently cleaned the contacts on both the LCD and PCB panels (Don`t spray the panel or this could penetrate) by spraying a small amount onto a tissue then gently wiping this into the nooks and crannies with a nail brush then wiping off the excess with another tissue. I`ve had no problems since, (touch wood). Please use extreme caution when working with these panels as they are dedicated to your keyboard and therefore extremely expensive to replace. If yours has an extension lead from the LCD panel to a plug on the PCB, it should be a lot easier to clean this one cable where it enters the plug on the PCB than mine was, but still use extreme care. Best of luck, Ian

SOURCE: Which midi cable or USB midi cable should I use for Yamaha DGX 520 model.

It doesn't use a USB to MIDI adapter (such as the UX-16.) It has an onboard MIDI controller and uses a standard USB A-B cable. You just need to install the driver from the CD-ROM or here, and plug it in. You can get the manual from the same page or here. Setup is on page 99.

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.
