    If ypu lose power when upgrading your device sofware, you letterally fry your device firmware . The machine now is not able anymore to do post test, it won't perform startup prcedure, and it should not be able to perform normal operations.
    If you can connect the machine to same or different computer, and the amp is seen by the computer you can restart the software update and finish it, this will fix the problem.
    However it is unlikely that you can establish communication between your MC 12 and any computer if the machine is in conditions descripted above. And you cannot-home install the firmware if you cannot connect mc12 to computer, you will need to reprogram the firmware chipset.
    The only solution in your case is taking the device to a service shop and asking a firmware upgrade, they will flash your mc 12 memory with required firmware, and you should be able to use the device again, usually this is not an expensive operation.

    Also small rectify to above, your software is not stored on a chip, but on the HD, the result does not change, If the device does not boot to finish the software install you need to call a service to have The HD image restored.

There may be a secondary fuse inside the unit, if not the problem will be in the power transformer, if you are handy with a digital post back and I will give instructions on testing the transformer.

Troubles during the upgrad from V2 to V3


Hi Louna_st
There are apparaently some hardware upgrades to be done also to get the v2-v3 upgrade to work. try the following procedure to get the unit back to v2 again and at least get it operating.

To reload v2 turn off the MC-12. Hold down the four buttons in the middle column of the middle zone on the front panel and turn the MC-12 back on from the rear panel. Keep holding the buttons down until the Lexicon says 'waiting for download' on the front panel. When it is like that you should be able to reload v2.
