Those are actually called 7 segment displays. Each segment is an individual LED making the number 8. It' probably a bad connection or a burnt out IC.

I supect that display is a component on a circuit card meaning all the 7 segment displays are soldered to a common board. Unlikely you could fix it yourself. Just getting to the board would be very hard by looking at my T6i. I'd send it in that way if it's not the circuit board and something else you know it's going to get fixed and not you just changing parts. I work on robots for a living and I wouldn't even attempt to repair that myself.
