One of my 800MK2s is displaying the error E-8709.
Let me describe the symptoms that led up to this error... The unit was randomly powering off and back by itself and would power cycle until I manually powered it off and back on myself; then it would work fine. This wasn't happening too often.
Then just the other day it was in mid-song and it frooze, no more playback, no buttons doing anything. So I turned it off and when it powered back on, it said "power on" for an unusually long time, then it gave the error E-8709.
From here, I powered it on and off and the error remained. I powered it on and off a few more times, and all was good. I was not able to play it for a very long time after this because I had to leave, so I'm not sure if it would freeze again. When I got back home, I powered it on and the error was there. I restarted it a few times and the error went away again.
It is obviously not very reliable for a gig or recording.
I'm posting here because I'm not trying to spend much money on a repair, so if this error typically leads to an expensive fix, I just want to know now before I take it to a technician.
I've searched the web, and there never seems to be the same solution to the problem. This seems to be the general consensus on the error's meaning:
E-8709 Communication error between operatin section and main section The error indication is cleared when the communication is finished.
Error code 8709 is a communication fault between the control interface (the PCB with all the switches on) and the main PCB (the motherboard in the base of the unit)
It sounds like this is a communication error between the top part of the unit and the base part, but this could mean a lot of things I think... like the ribbon cable connecting the two or the actual boards themselves.
So can someone maybe advise any troubleshooting steps or information/ideas?
Thanks.
