Default Ever had a bad day ... ?

And the week had been going so well ...

POS Numark dual CD DJ deck. All working, except only one channel on the Aux
input. Opened it up and the top (large) board is connected to the bottom
(large) board by two white flexis. At one end, they are in the typical
'Panasonic-style' ZIF connector with a white body and brown latch. At the
other end, they are in a non-latched white push-in connector. And of course,
they are just slightly too short to allow the two case halves with their
boards, to open apart enough to sensibly take readings. So one of the flexis
pops out of its push-in connector. So I switch off and plug it back in, and
guess what ?

Now, the hateful piece of garbage just sits there with both displays saying
"BOOT NUMARK".

I can't help but think that it is inviting me to boot it down the road to
the nearest garbage dump ... :-(

Before reinsertion of any non_ZIF socketted foil type ribbons I always
wrap some cloth reinforced tape around the end to avoid the ribbon
bending at the weak point. I wonder if the assemblers have a special
pair of parallel jaw long nose pliers for reliable insertions.
