Saab SID display

Hi, I'm wondering if anyone here has attempted (and hopefully had
success with) repairing their own Saab SID display.

These System Information Displays are renowned for having segments of
the display go dead. The problem is caused by faulty connections
between a ribbon conductor that connects pads at one edge of the main
board to the (separate) display unit. My understanding is that Saab
chose to attach (and connect) the ribbon conductor to the main board
pads using some sort of conductive adhesive. Over time, the
connections become intermittent and you start losing rows and/or
columns of the segment display.

There are a myriad of fixes for this on the Internet along with
replacement SIDs for sale on places like eBay. Most of the fixes
involve applying additional pressure to the adhered connections to try
to reestablish continuity. I've tried these but those that give some
improvement don't last.

So I am wondering if anyone has tried to repair one of these
themselves and what success you've had. I was thinking of trying to
replace the existing ribbon cable with either something thicker or
something wire-based so that I could perhaps solder the connections to
the board using a low temp solder.

Any info/insight/experiences are appreciated...
