Nord Electro 2 Errors E7/8

[Bytes]

Hey all,

I've recently acquired a "broken" Electro 2 from my uncle. It was initially given as broken (not dead but throwing error codes) but after a tactical drop by my brother while carrying it, it was fully fixed for a while.
Skip forwards a month and I've moved it into my new place and it seems like somewhere in transition it has regressed to its old ways. Currently it does one of three things upon power up:
1) El -> E8
2) El -> E.7 -> rd
3) El -> working for about a minute with progressively more weird effects -> loud pop in headphones -> E.8 (I think, this happens infrequently)

Weird effects start with the volume coming in and out (like you'd imagine if you put volume through an LFO), then the patch numbers go weird as you move through them, then it pops loudly and dies.

My question is: what does error code E.8 mean? I opened up and checked the ribbon connections plus looked in to re-flashing as suggested by the manual to address E7 but can't do it right now due to the Windows driver not being compatible with 64-bit Windows 10. What is the best way to handle that and what else should I be looking to do?

Cheers,
Bytes

BootPROM error codes:
E.0 Recv SysEx error (overflow or other low level error)
E.1 Recv begin error (SysEx begin message error)
E.2 Recv data error (SysEx data message error)
E.3 Recv end error (SysEx end message error)
E.4 OS erase error (can't erase OS in Flash)
E.5 OS write error (can't write OS to Flash)
E.6 No OS detected (no OS in Flash)
E.7 OS load error (OS with errors in Flash)
E.8 Flash init error (can't init Flash chip(s))
E.9 Flash unknown (unknown Flash chip(s))

Sounds like the OS flash partition is either failing or has a bad connection. Not sure if it’s soldered or if there’s a cable that might be usefully dis-/reconnected, but I’d think it’s time for service from someone technically capable of reflowing solder on an SMD board.

I’d think it’s worth it...I’ve worked with a Stage 2 for years and am now on a Stage 3, but I’m still keeping my Electro 2.

Given that it was working for a while after the drop, then it wasn't, my theory would be loose connections in the board. Shouldn't be that hard to open it up and re-seat everything. And, if that doesn't work, go ask Pablo for a tech in your area.

Cool thanks guys, I'll have a quick look at what I can prod at around the flash chips then look for someone to service it.

Out of topic but I'm always amazed at the number of very technical aspects of the boards that Analogika knows....

Indeed! Impressive it is.

Er...thanks for the flowers, but nothing particularly impressive here, as far as I'm concerned...I just happened to have the service manual in my document archive...

Hi everyone.
I hace a big problem here with my Nord Piano 4.
Turning it on display says "Piano Flash Error Init Fail [0]"
My computer does not recognize the piano via USB.
Really don´t know what to do.
Is there any combination of buttons to hard reset or something like that?
Thanks for your help
Andrés

Hello Andres, I am afraid this could be a HW fault that needs to be checked by the official/authorized Nord service (contact your country distributor to know which one is teh nearest to you)
