I don't know what the original problem was but here is your service manual:

Scroll down to "get manual" and click on it to download a PDF file of the service manual.

Ignore other download links for viewers etc... If you have trouble, contact me at fredy2 at aol.com with YPG in the subject line.

Read about initialization on page 61 of your user manual. This is a factory reset. There are two procedures there. If you don't have the manual download it here:

Hi here is the manual of your Yamaha

You need to down load a unzip utility program to open the zip files. You could try this link: http://www.freedownloadscenter.com/Utilities/Compression_and_Zip_File_Utilities/PKZIP__32_bit_.html

The reason they are zipped, is that this makes the files a lot smaller. Smaller files are easilier to transfer, store and to download. The unzip utility will restore the zip files back to their normal size. Hope this helps you.

I have the same problem, mine is Yamaha YPG-625. This seems to be a common problem with Yamaha keyboards. I opened the 100 screws in the back, separated the main board from the display unit which is under it if you flip the keyboard upside down, to verify if there was any loose wires, nothing of the sort.
It is so frustrating, the keyboard is working fine but it is hard to navigate because the display is not functioning. Yamaha should do a recall as this is obviously something wrong with the keyboard happenning to a lot of people

Do a factory reset. First try pressing the + and - buttons simultaneously.

Look in your user manual for a complete factory reset and do that.
