Yes sounds like what Tony is saying. Lower YDRV board faulty. It's also recommended to replace YSUS as well.

After replaceing driver boards you may get away with soldering joints in Y sus instead of replaceing it

mike pritchard, thats interesting. Which parts dry joint?
I've only ever replaced YSUS, if you dont YDRV will fail again.
