Not booting after upgrade to latest version

I expect you updated the wrong version or it crashed before it finished updating.
The only version is v3.06. Any other will crash it permanantly.

This might work; https://usa.yamaha.com/support/faq/keyboards/1478.html

RESET / Hold these buttons or keys and power on Insert System disk. Hold POPS and power on. Display shows FIND SYSTEM and starts the loading process. Which version do I have? / Hold these buttons or keys and power on Input the following number code: 00009584 or look at Start Screen Which version is the latest? 2.46 How can I get the factory sounds back? RESET

Probably your battery packs won't hold a charge any more. See my post here

My Yamaha MM6 Synth is showing blank (white) screen when switched on. Keyboard sounds and banks are working. Everything looks nice but not showing any details on screen. Any help.....

If this is a flash upgrade to the unit be VERY careful as a failed upload can leave unit dead. They usually have pretty tight checks to prevent an error from killing the unit during the upload. For certain music products I have found that I had to upload an in between version first that was available before uploading the latest current version.

from the akai forums:


to set the os back to factory settings press and hold the erase key till the mpc has booted to the main screen.

to erase the harddisk goto either the load or save screen and then choose utility - there you will find the option to format the hdd.

you can also format the drive (or any inserted compact flash-card) from your computer thru the usb connection, but it is recommended to use the internal format because the mpc can be a little picky when you format it from the outside.

at first i would check if there is any folder or the internal memory is set to autoload and just turn that of or point it to another folder of you choice. that way you can keep the factory delivered sounds. maybe you want to use them later, even if it is just to explore the mpc. the factory sounds can be also downloaded later, but be advised that there are different iterations of the stock sounds, depending on whether your mpc shiped with a 32 or 128mb compact flash card.

also the mpc os is not on the harddrive but in the internal memory. to check the version hit mode-> pad10. latest official version is os 1.24. if your main srceen looks different than in the manual check double and triple before you do anything, because the previous owner might have installed the third party jj os which comes in different versions. some of them cost a lot of money! if you find this check the other forum here for the alternative os.

Try getting the newest version of your OS. there are quite a few programs that are compatible with a certain operating system, but you need the latest edition to get them to run.


Hope that helps!

Hi, sorry I can't solve it for you. I have the same problem with the VF-1. I flashed the unit to upgrade it. All seemed fine but when I turned it on all I got was the light powering on and a blank screen. Also how do you reset the unit without going being able to use the menu. Is there a key combination??

Hi Good day!!! what operating system you use?

It sounds like you have either a hard drive failure or have lost the internal operating system in your unit.

BE VERY careful if you have critical data as it still might be recoverable.

I would contact the factory on this one.
