I did and everything lines up, but if I rehome my T axis lining up my scribe marks it does give me absolute data different than what my original is supposed to be

What are the steps to remaster?

Hey guys hoping someone might know what I have going on here.
We have dual arm MA3120 robots with a DX200 controller. R1 has seemed to lost its repeatability, parts that we have been running consistently for years with no issues. This started about two weeks ago after we lost power over the weekend (dont know if that has something to do with it, pm was just done 2 months ago) Some welds are off up to 3/8" but not all welds are off.
Things that have been confirmed (Fixtures, TCP, Second home position, concrete floor lags and all hardware, breakaway, torch, wirebreak, belt tension)
The welds in question seem to come back into the joint by spinning -T axis about 3000 pulse counts
We had a tech in and said that nothing from the eye test seems to be wrong without tearing the arm apart. The machine seems to be repeatable now, just not to our original programmed points.
Is there something that I am missing here or other things we could try to prove what might be wrong. Yaskawa customer service seems to think the T axis motor might be going bad, but robots are only 5 years old running 1 shift of production.
