For part relacement, If you are not sure.
Give me the number on the side of 7 segments led.
I expect, the courant(I) On led is a little bit to High.
Most of the time, To have a good light
the manufacturer recommanded to use it a the maximum courant(20mA).
But it is possible to use it at 10mA or 15mA, and the life should be better.
In this case, it is needed to change the resistor in Serie with.
