[Dead] Sharp MX 3070 E7 A7 Error Code. Machine powers off and on now

[Doug James]

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 ?

E7 A7 error code? is this the correct code?

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

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

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 !!

Yes 1 pwb.

1 pwb, but 2 eproms. Both must be removed and moved to new board if replaced

In the MX-4070 Service manual, Page 7 - 2 SELF DIAG AND TROUBLE CODE

E7 A7 is "SSD breakdown". Might be having trouble with that awesome new mSATA!

Weak part just like the SD's.

I concur. mSATA. I've had 2 go bad on relatively new machines.

I just had to replace the mSATA card on one of these machines the other day

Before you replace anything though, remove the MFPC cover plate with the machine on, and look for the green lights. There should be two sets of four lights next to the mSATA card, and one set of four lights at the bottom of the board. If any of the lights next to the mSATA card are not on, replace the mSATA card, and if any of the lights at the bottom of the board are not on, replace the board

After replacing the Msata, the control panel won't work. At this point after inserting and playing with ribbon cables for seems like hours... lol I am blaming it on the MFPC Board. I attached a pic of the lights above Msata board. The 4 lights by the rom are all on

I really appreciate all the replies more than you know. I'm starting a new thread on this. Still having problems with this machine. I replaced the controller board and that fixed the control panel but now it won't come out of the CN mode and when we try to load firmware it say's code error.

What was your ultimate fix on this issue? Just received this code today on a 4070 and am bringing the msata and the mpf board. Is there a successful way of cloning the msata cards?

Yep, I am not sure what's involved or where to get the software but there are techs doing it.
