Replace, take the old unit back to the workshop and repair as required.
Worked for me for 40 years. Except it would be dump it on the bench and tell the mate to repair it.
There was a skip outside the shop when all else failed.

you will find some fittings are wired differently even if the ballasts are rated the same. Some ive seen have the tubes in parallel some in series. Some are HF and some are switch start. For every site I manage now I have 2-3 spare fittings I have already repaired and now I just swap out and rewire on my bench as Tony mentioned above. I try to keep ladder work to a minimum. If I come across a switch start I am replacing with HF. Always try to get the same ballast if possible also as it saves loads of time rather than redrill new holes replace short cables etc etc

just take your time on the jobs, its not a race.

i had a mate who treats all this jobs as a race lets just say, he made some errors
