Now what's weird : so i opened the beast and put it flat
(horizontally) on my table. i hit "play" but the key won't stay
locked. i have to keep my finger on it. same for rewind/forward/rec. i
dealt with it and thought i'd see if it does it again when the machine
is re-assembled and standing vertically on its feets. but the same
thing still happen.

any idea of what's going on ?

You pulled the shorting plug out of the remote jack. Page 3 in the manual.
