I have fixed these years ago, without buying new wafers
Dismantled it quite easy, on the wafer first check/measure with a magnifying glass the lead in lead (circled in red) out tracks for breaks,
The the continual ribbon itself.
If you can see the break you can with a pin and steady hands put just the smallest dab of quality electrically conductive paint/glue across the crack you’ve found, without joining the adjacent track to it, wait for it to dry properly. https://ibb.co/BwpG8Lt
