Unfortunately yes, my ST7000 had a major failure. The main PC board went bad.
There was no way to get it working as it decided to announce "low batteries"
and bip for ever as soon as I would try to crank it.
This happened in Grece and the repair agent in Athens found nothing wrong. I
reinstalled it and of course, same thing. I had to get a brand new PC board.
