A broken chip is stuck in the segment and cannot be removed.: Use pliers or similar tools to pull out the broken dart tip.
If it is stuck in a hole and cannot be pulled out, you can disassemble the board and take out the segment, then use a chip remover or push it from the back of the segment as shown below.

Never try to forcefully push the segment in with a chip remover or something with a sharp tip without taking it out, as this may cause damage to the sensor sheet.
