I have some similar problems with my Mx-80 and thought I would continue the post...
sometimes when i power up I get error 90(initial communication error) and the remote wont do much or nothing then after 15 minutes lights come on the remote and it's fine for a while and then sometimes the remote conks out again
sometimes when i power up I get error 92 (endefined error) but only for a moment and then all is ok.
the error 90 can be a real pain as the remote will work partially(transport functions work but record enable wont work and time display stays on whatever time it was on when the communication failed again)
dan Zellman did a bunch of work to correct this when it happened last year but it is back.
someone said it may be noise on the ac line causing the error and I did see a bulletin from otari about that but so hard to tell if that is the cause. I dont think it is.
anyone else have this problem?
all cables and connections are good
the power supply was rebuilt
it is the first year 1986 verison but software is the latest.
the intermittent problem is such a pain to track down
as soon as a tech shows up it works!!!
any insight or ideas about what to do would be great
thanks
