PROBLEM WITH THE OS UPGRADE

I PUT THE OS 2.11 ON MY MPC AND NOW MY MPC WONT TURN ALL THE WAY ON. WHEN IT CUTS ON THE SCREEN JUST STAYS GREEN. PLZ HELP

Get the JJ OS. It's not Akai supported, but hey you can't find those guys anyway. JJ OS Version 3.06 has more features than Akai's 2.1 and is free. It can be found and the following website:

I hope this solve your problem.

reset to defaults

I believe you need to hold ERASE as you turn on the machine

You need to adjust your contrast... I can't remember what it is on the AKAI os... maybe hold down shift while you turn the data wheel i think... that was a common problem people had after upgrading.... the contrast changed.

Also, do what wook jr said. The JJ OS is way better than the AKAI OS.
