The probe transformer is easy to damage. It's sensitive to physical shock. When you can't balance out the DC on low ranges, it's very likely that the Hall sensor has been damaged somehow. Can't be fixed AFAIK.

I bought three P6042s over the last few years and all of them had cable failures. Tektronix did a lousy job on the strain relief where the cable enters the enclosure. I just shortened the cables to get rid of the faulty sections. None of the transformers were broken, but maybe I was just lucky three times...

p.s. I paid about $200 on average for each of these

The problem is that the transformer is very fragile and is almost invariably the broken part. It is also unrepairable.
Spare transformers, if they are good, could in theory help revive a "for parts" unit into a "for use" unit!
Have you seen the prices for P6042s lately on eBay?
