Sorry to burst your bubble but learning from those that have seen what you
are seeing is money in your pocket. You will spend thousands to get the
box back in working order. I suggest buying a rebuilt one with warrantee
from a rep. rebuilder or do the
Smitty thing.
I purchased 5 used boxes and managed to squeeze out one good rebuilt one.
To
much abuse over the years just wipes them out.
