Hi,
I am using a TC7107A IC to run 3x 7-Segment Common Anode displays (LDS-SMHTA304RISITR). I've drawn up a rough schematic, but it's nothing that deviates much from standard recommended circuits.

The display works as expected... at first. It has no issues on startup, even if I cycle it multiple times per minute or wait 20-40 minutes between startup cycles. BUT, if I go home for the day, the next day when i power up the circuit, several segments no longer...
7 segment failing on startup.
