Repair of LCD display

Display is unreadable and intermittent.
Is it the display drivers or the LCD panel itself?
Can I buy parts and repair it myself?

Intermittent Display
by: Alfred

Dear Stephen: One thing at a time. Some Displays are indeed difficult to read due to small size. 1) Changing the angle-of-sight might improve legibility. Either raise or lower your bench to
see if there is any improvement. Also, if the Display is back-lit, keep any external lighting away from the keyboard. 2) If back-lit, the Display's internal bulb may be burnt out. 3)
There may be a disconnected plug-and-jack lead to the Display.
As to DIY repairs, I've not yet tried fixing any such SERIOUS DEFECTS. It's probably far more complicated than you think, and depending on the age of your keyboard, the intrinsic value you place in it, and the cost of professional repair, you have to decide what to do. I can tell you this: Displays are generally replaced, not repaired, and the charges can be high. I wish I could be more encouraging. In any case, please post a comment as to what you decide so all of us can learn from your experience. Thank you.

LCD Problem
by: Alfred

Dear "Anonymous": Your unit is obviously very new. Yamaha released it in 2008 and I am not familiar with it. Hopefully you have the OWNER'S MANUAL. Some Yamaha models have a control for adjusting (contrast of) the Display and you should check to see if anything is mentioned about such a control. If I'm correct, please post a follow-up message in this Forum so other members can learn from your case. Also, please remember to enter your name (not "Anonymous") if
in the future you want your problems to be properly noticed and answered by members who can help. Good luck.

DGX-630 Display fault
by: Justin

I have the same problem with mine.
Over time part of the LCD display has become lighter and lighter.
Now only part of the display is visible.
The display its self is very obviously faulty.
Does anyone know who sells parts for these?
Im guessing Yamaha sell them but i cant find where.
Many thanks.

Bought this not quite three yrs ago and the light on the display has gone. The display is there but seems like the background bulb has gone. My friend also bought the same after my recommendation and the display on that is totally gone. Think there is a problem with the display on this model yamaha. I took out an extended guarantee with rimmers music where I purchased it . They will take my piano away for three weeks and repair it but I have to pay £45 courier charge. Am sure is only the bulb on mine and as I had warranty is wrong I should have to pay. Anyone know where I can purchase a bulb am sure cud fit myself. Thanx

Yamaha DGX 520 keyboard
by: Bert

The background light on my keyboard is on & can be adjusted to light or darker blue with the contrast control but no writing is displayed. Can this be a power source problem?
