Re: Sharp MX 3070 E7 A7 Error Code. Machine powers off and on now

look at TT-051816_1R1. It has to do with boot failures.

I looked over the Tech Bulletin Thanks so much for that.. Really helps !! I am confused at what the SCN-MFP PWB is... Is that the entire controller board"MFPC" Thanks again for your help !!

Yep, sure is... I had to take a second look at it myself...

When I came upon this machine for the first time it was showing E7 A7 error code. I turned the machine off (Behind the front door) and the machine will start to boot up and the power down over and over. It will not boot up... I called Hytec and they thought it was the "boot-rom" card on the controller. Has anyone seen a boot-rom board go bad on a 4 month old machine ? Should I replace the whole controller or just figure out how to get the boot-rom ?
